How To Grow Ranunculus. Soaking, Presprouting, Planting, Covering, Harvest // Northlawn Flower Farm

- Here's how to grow ranunculus. Your growing zone and particular growing situation will dictate when your ranunculus should be planted. Zones 7 and higher or those with high tunnels can plant them out in fall. However, those in colder zones with no greenhouses should plant in very early spring. I am in 6b and do not have a high tunnel. I find that planting them out approx. 4-6 weeks before my last frost date and protecting them with a low tunnel made of wire hoops and frost cloth works best for me. Don't plant them outside until you are sure the ground won't freeze. Experience is the best teacher - especially when it comes to ranunculus. Everything that I'm sharing with you today is from trial and error on this particular land and in this zone. You will need to adapt to see what works best for you. You can find links to other grower's in other zones at the end of this tutorial.
In my zone corms should be planted out approximately 4-6 weeks before the last frost. Before planting I soak and presprout to give them a head start. This should be done 2 weeks before planting out.
When you purchase ranunculus corms they will be shipped to you in a dry dormant state. The corms can be stored dry and at room temperature for several months. No special treatments is necessary. Plan to start the soaking and presprouting process two weeks before you plan to plant them out in the garden.
Place the corms in a bucket of room temperature water and soak them for 4 hours. The water temperature should never exceed 55 degrees F. I place mine in old daffodil bags so they are easy to lift out of the bucket. Change the water every hour to avoid the build up of bacteria. You can also use a fish pump to arrate the water or leave a gentle stream of water running in the bucket for the 4 hours. I find simply dumping the water every hour works just fine.
Once the corms are soaked it is time to presprout them. Presprouting will result in blooms about 3 weeks earlier and will help us weed out any "dud" corms. Fill a planting tray that has no holes with lightly moisten high quality potting mix to the depth of about 1-2 inches. It is VERY important that the soil is not wet, just lightly moistened. Place the corms with the tuberous fingers pointing down in the medium. They can be placed very close together. We will not be growing them in this tray - just presprouting them. Cover the corms with a light layer of lightly moistened soil. Once again - not wet - just lightly moistened.
At this point some people will tell you to cover the tray with a dome. I personally found this problematic so I do not cover the tray at all - however, find what works best for you. Place the tray in area that stays dark and cool. The ideal temperature is 50 degrees. The soil should stay slightly moist during this time. Never wet, and not bone dry. Leave the tray in this cool dark area for approx. 2 weeks. Check them every day or so for any signs of rot and discard any corms that are moldy or rotten immediately.
Once about 2 weeks have passed you will see that the corms have developed roots and have begun to sprout. This is the right time to plant them out in the garden. Once again try to correlate your presprout with the time you want them to go out into the garden so that you are not trying to hold over corms that are ready to go outside.
Ranunculus need full sun and well draining soil. The plants can take cold ground and cold temperatures, but the corms should never be allowed to freeze. Before planting, incorporate a good 2-3 inches of compost to the bed. Plant the corms 2 inches deep and about 9 inches apart. I have head some growers push the spacing to 6 inches apart, however, I have never personally tried this.
Next I hoop and cover my plants with a frost cloth. I use Agribon 30 and metal hoops that are bent by a local farmer. I use metal staples to secure the cloth to the ground.
Ranunculus open in the day and close at night. Harvest Ranunculus after they have opened and closed a few times, generally 3 days. If the center bud feels hard, wait, and check it the next day. It should feel squishy like a marshmallow. Harvest in the early morning. You can cut them more open, they will just have a shorter vase life. You can expect a vase life of 10 days.
Once the weather warms up you will see the Ranunculs start to go dormant. Don't worry, this is normal. Ranunculus do not like long hot days and will stop producing when temperatures are consistently in the 70s.

This is the 5th video I watch about this subject and you are the first one talking about the storage (temp. and humidity) during sprouting. Thanks so much for this short precise video.
This is by far the most detailed and informative explanation of ranunculus I have found on TH-cam. Thank you.
Do you save corms or buy new each year? And keep up the awesome videos 🥰.learning a lot from you!
TY! I have watched 7 vids & you are the first and only one that has mentioned that the flower closes up in the evenings and opens back up during the day. 👍🏻
Thanks for the encouragement, Danielle! I have some pre-spouted corms in the ground now (Zone 9b in Southern CA.) and I hope that at least a few come up in the Spring. :--) I appreciate your comments about being patient with ourselves.
These are such beautiful flowers!!
Good morning ,
It’s Spring... thanks for sharing 🌷
#1 fan from Pittsburgh
Thank you so much! Your video really helped me. My corms are sprouted and now growing in my garden! I didn't lose at all so far knock on wood. Thank you again!
Thanks! I followed your recipe except I planted each bulb in their own small pot. Placed them in a dark, cold room and all 20 of them are sprouting.
Wow! Great job, this is the absolute best video I have ever watched on ranunculus! Of all the ones I have watched, none of them have mentioned that the blooms open and close, or that they will stop blooming around 70ﾟ!?! I presprouted mine too early! I started presprouting them mid January. And although I'm sure my temperatures have been warm enough, I didn't have my cutflower bed finished! They're already starting to bloom really small blooms in the trays on really short stems...
You are too kind friend! I wish I would have said it's usually about 3 days of opening and closing. Hank Onings has some really interesting charts on them. I can't figure out how to link them, but anyone is welcome to DM me on Instagram and I can send some screenshots on season extension as well.
@@NorthlawnFlowerFarm Oh OK! Awesome ty!
Thank you so much!! This has helped s much
I am in zone 8b and my Ranunculus have sprouted. I will be planting them out today or tomorrow. It's my first time with this process you have just mentioned.
Thank you so much. 😊
These flowers are so beautiful and small great too.
Thank you for the heads up! I’m in zone 9B and this’ll be the first time I grow these! Can’t wait. Thank you!
Very good and detailed ‘how-to’ video - thanks a lot for sharing!
And the best advice I’ve heard “just about getting out there and doing it”. Works perfectly in many situations!
very helpful, especially the tip about moisture.
Thank you for sweetly pointing us to the growing information for our zones. I’m in 8b/9a and most of my favorite gardeners are in much lower zones. I still love watching and learning (of course!), but it is nice to have information that is accurate for our climate, too. 💗💗
Same here! Thanks for sharing more information. I live in 9b and am always looking for other channels who can help me in my zone.
Me 2 ! 😊
Me too…9b - Coachella Valley, Palm Springs - my question is whether they will return next spring. Do I need to do anything special with the corms over the long hot summer? Also, in my particular area we have not seen a frost for probably the last 10 years or so, whereas it used to be a regular thing. Does that make a difference to the corms? Should I refrigerate them?
I have the utmost admiration for those who have to cope with harsh winter climes - yet still manage to have exquisite gardens. Luckily - here in New Zealand, the majority of us live in temperate zones (except the deep south and the mountainous regions). Currently my ranunculus corms are in the fridge (along with the anenome, tulip and hyacinth bulbs). We have to trick them into thinking it's winter. My daffodil, freesia, muscari and Dutch Iris bulbs are in the ground and already popping their shoots up. I'll be planting the refrigerated bulbs in early May (late autumn here). Your vlogs are just choc-full of fantastic information Danielle. Thank you so much for taking the time to educate us all - your fellow flower lovers.
Your video gave me confidence! Thank you for all the details including putting them in the ground!
Happy spring Danielle! Excellent growing tips! Unfortunately when I purchased the ranunculus plant last year the squirrels love eating the buds!
I love these flowers 🌸! ❤️🇨🇦
very helpful
Great video! Trying ranunculus for the first time in 7b. I planted in November after soaking but didn’t pre-sprout. I’ll do that next year for sure. Mine were unprotected despite 20 degree nights and are close to blooming now! They are tough!
As always quality content from you and awesome you shared other resources. QUESTION - do you dig these up in the Fall like Dahlias?
I love your videos. Thank you. I planted 475 ranunculus in a special bed I prepared. Planted in the fall and had a great crop growing well, going into this past winter. Then…either mice or squirrels ate ALL my corms! How in the world do I prevent that? I didn’t realize rodents even liked these corms!
This video was a huge help for me. Thank you so much!
Thank you so much for this video. Concise and relevant information on ranunculus is impossible to find until now. I appreciate your generosity in providing links to other gardeners in zones closer to my own. This is my second year trying ranunculus and hopefully I will get a bloom this time. Just one flower would mean success to me. I have 4 corms that have leaves...out of 20 I purchased from local big box hardware store/garden center. I garden in 6a/5b in New York. Happy spring when it actually arrives ☘
Very good information! I have watched several other videos and yours makes it clear what I have done wrong. Thank you, Pam Smith
Before sow the crom.. i usually put some fungicide on the crom.. the percentage of growth will slightly higher..
I am learning so much from your videos, rewatching your tours from last year and loving them.

You are my favorite flower farmer that I follow. Your explanations are clear and easy to follow. How long do you leave the cover on the tunnel? Thank you!
Love that you have links to certain zones! Our 4a is tough gardening here in Upper Peninsula Michigan..... but I am going to give it a try! 🌺🌼🌸
Watched this morning and planted mine for pre sprouting tonight!! Debating if my soil was a little to wet 👎🏻👎🏻👎🏻
Such a great tutorial! I had never heard of this flower before I saw one of your previous videos. They're absolutely beautiful!!! Do you then lift the rhizomes in the fall and store or do you consider them annual? I live in Michigan, zone 5b.
I love the stand you had your arrangement on. So beautiful. I plan to try ranunculus next season. They are such a lovely flower 🌸
thank-you Danielle for sharing your knowledge - you are always so generous :-) I am very hesitant to "experiment" with these because they are so expensive here in Canada (18$CAN for 5 corms), the "some loss is expected" is tough, despite their beauty!
My ranunculus corms were sent to me with my glad corms!!!! So they are ready to go out but it is very warm here now in 5b. I am hoping that they will still grow because they sprouted beautifully. Any tips for me please????
Hi, what do you do with your corms after the flowering season is done? Do you dig them up and replant them next season (after storing)? Thank you.
Yes indeed. First day of spring and it was freezing here too. I don't mind the cold but a strong north wind was too much. I tried weeding for an hour but came in frozen and decided that an afternoon beside the log fire was a better idea. Hopefully the Artic blast will pass in a few days and we can get back into the garden. I love the colour of those Ranunculus and the pre sprouting is definitely working, they looked lovely and plump before planting out.
I am such a rookie when it comes to ranunculus! I pre-sprouted 170 too early I think? I was so paranoid about mold and mildew that they dried out. UGH! Hopefully some will survive so I don't give up permanently. Thanks for your videos! They are SO very helpful.
Just about to plant out sprouted corms in patio pots today, first time trying! Thank you for the confidence boost video!
I did the same today and my first try too. I was amazed how those little corms grew so many roots. Good luck to us!
@@betsymaltby6788 Awww yes! Good luck to us and our beautiful flowers!
You are a wealth of information AND guidance.
Great video!
Thanks so much for the info for other zones! I really appreciate it. My first attempt at growing ran in s was a dismal failure. This year 18 of 25 corms have sprouted and are happily stretching their legs. Now, thanks for your zone 3-4 link, I will be able to have my first tannic, (hopefully).
Very helpful tutorial! We’re going to grow them for the first time this season. We’re in zone 5b. After they’re done producing do you treat them as an annual or can they be dug up and saved for the next growing season?
Hi there! I treat them as an annual, but you can certainly let the foliage die back and dig and store them! I believe I have seen Dahlia May Flower Farm share about this on Instagram. You might get some more info from her! Also if I remember correctly she is zone 5 as well!
@@NorthlawnFlowerFarm thank you!
I'm trying them for the first time too! Good luck to us both.🌸
I'm super glad I've found your channel, your videos are so helpful. I'm from the UK so things are slightly different weather wise etc but I find the majority of the information so helpful. Especially because this is my first year flower farming ☺️
One thing I never see discussed is when to dig up your corms to save. I don’t know that many ppl do save them, maybe that is why? Once the heat kicks in and they finish flowering is like a bulb where there need the foliage to die back to feed the corm?
Thanks!
Thank you for this! I'm so excited to grow these in the near future!!! My friend successfully overwinters ranunculus in a low tunnel here in 6b (Mt. Joy, PA)!!! You might want to try it?! Obviously more work, but such reward with early blooms.
Thank you so much for letting me know! Is her low tunnel plastic?
I live in the same area! I would like to know what to do for success here too!
I’m in a zone 9 and have always just thrown the dry corms in the ground in October and they have been successful. Last year I presoaked and was not as happy. This year I’ll personal and prescription half and just toss the other 1/2 in the ground and see what happens.
I love your honesty
Thank you so much.
Uh oh... think I probably messed my first ones up. Put them under the grow lights on a heat mat 🥺 Guess I will fix that and see what happens 😅
I have a box of 200 coming this week...I’m so excited. This video came just at the right time!! Thanks 😊
where do you buy your cromes from!?🤔 I appreciate your time!!‼🙏😇🤠
Thanks for this clear explanation Danielle :) What happens once they've finished blooming? Do you harvest the corms for the next season?
After the plant dies out yes, harvest, dry them and store
@@locusttreegarden1560 Thank you :)
I would have loved to have gotten a look at the ranunculus plants in the bed! People always show the beautiful flowers but not their growth habit. I put mine in the ground a couple weeks back, but we’ve had a lot of heat. Not sure what will happen 🤷🏼♀️
Hi there! I wrote an article on Ranunculus for Longfield Gardens recently. You can see my seedling bed at the end of the article - www.longfield-gardens.com/article/10-Tips-for-Growing-Ranunculus
I hope that helps!
Hi Danielle
I just watched this video again to avoid another ranunculus massacre this year. I have been pre-sprouting mine in my unheated zone 6b garage under a frost cloth for about a week. Definitely seeing signs of life! Should they be hardened off before planting outside? Also, could I put them in pots for another week or so before planting them out. I worry that the weather in SE Michigan might get too cold without a hoop house. Thank you!
Perfect timing, thank you!! My presprouted corms are ready for planting! 🤗🌸🤗🌸🤗
I am in zone 7A. Do you think it’s necessary to cover them with the frost cloth here?
Hi there friend! Are temperatures dipping below freezing at night? If so I would cover. AG 30 will give you 6 degrees more. It shouldn't cost but $8 or so for 20 feet.
@@NorthlawnFlowerFarm thank you!!
Hi and happy spring. This is one of my favorite flowers but have always heard they are challenging to grow. You inspired me to give it a try!! But you skipped over people in Z5 😆
@@MEFROMCHI Hi there! Zone 5 should be able to follow my zone 6 instructions. Thanks!
This might be a dumb question, but do you pull the frost cloth back during the day (while it’s still cold out)when the temperatures are say in the 40’s or 50’s or do you leave them covered? I know I’m commenting on this in July. I’m just curious for next year. By the way, I’m in 6b also.
Good luck to me!
What county are you in? I'm in Bedford. I've been watching lots of your videos, but didn't realize you were a fellow PA inhabitant.
For presprout in the tray, we don't need sunlight at all? In areas with no frost in winter, can we plant them directly in the soil?
Bonjour,
Proposez-vous des bouquets, des compositions florales durant l'hiver ?... ou bien avez-vous une période qui démarre au printemps jusqu'à l'automne ?...
Je suis en zone 7b, en France, et en ce moment, en plein hiver, nous avons dans notre petit jardin, de superbes CAMELIAS en fleurs... en avez-vous dans votre jardin ?
Plus tard, dans la saison, aurez-vous des rhododendrons ou des azalées ?
Je trouve passionnant et magnifique votre jardin de fleurs coupées, dans un vrai jardin des 4 saisons, accompagné d'arbustes et de vivaces permanentes. C'est un vrai bonheur de voir votre jardin, toutes les semaines, et au gré des saisons... mais j'ai le sentiment que votre jardin offre peu de floraison durant l'hiver. Pouvez-vous nous en parler un peu ?... de votre choix de végétaux selon les saisons ? les périodes ?
Quels sont vos arbustes installés au jardin, pour offrir un beau cadre à vos fleurs annuelles ?
Merci+++
Bises,
Avez-vous comme votre amie Katie, des eucalyptus pour leurs feuillages ? (vu dans une ancienne vidéo)
Can’t we just plant them directly in the soil? They won’t sprout that way?
GREAT video on this
FIRST DAY OF SPRING!!!
🌱🌱🌱🌱🌱🌱🌱🌱🌱🌱
Haha! If you see spring, send her my way!!
@@NorthlawnFlowerFarm
I know, right!!
I sure will !!!
It's a sparse Spring over here in Texas too!!
I really appreciate you sharing what zone you are in and recommending the viewer referring to the links you've shared for growers in other zones! ⭐⭐⭐
Yes 👍
I am in South east England is there a comparable zone in America I can relate to?
Thank you for this video. I am in zone 7b and planted in pots a few months back. They have beautiful green sprouts now for at least 2 months but no blooms. Do you think I should feed?
I planted ranunculus for the first time and they are beautiful! What do you do with them once they are done. I’m in zone 9b, and we had a few days in the 70s in early April, and they stopped blooming.
I'm in 6b also! South Central PA. I made the mistake of ordering pre sprouted tubers from someone this fall, thinking that I can plant them this fall!! Didn't do my research!! What would you recommend that I do with them? Shall I put them up and store in a cool place, or plant it and hope for the best? I was also wondering if they would go back to dormancy if I didn't plant them.
Horticulturally, why the soaking and pre-sprouting step (apart from detecting any dead ones and how many of those do you really get?). If you presprout, then put them out into relatively cold soil, they'll check anyway, so I don't get the part about them flowering earlier. Honestly, it's a bit of a mystery. I don't presprout glads, daffodils or anything else... Have you tried at least dividing the little corms - maybe you'd get two shoots from some of them? Everyone seems to do this so I must be missing something..😅
Tomorrow (April 6) will be two weeks since I soaked and planted my corms. I've kept them in my cool dark basement and kept them moist but I'm seeing nothing above the dirt. Should I dig one out to see if it has grown any roots?
Do you dig them out once the temperature gets higher than 70s?
Help please! I soaked my corms and put them in soil + cool dark room like suggested. I think I under watered them, and they are shrivelled and haven’t sprouted. Can I re soak them and start the process again? Or should I continue watering them?
Thank you so much! You are a pleasure to watch, as you explain everything in such easy to follow steps. I can't wait to begin our flower farm next year!
The instructions for my Romance Maritime ranunculus say to soak for 12 hours (instructions from Fluer Farm). Is this a misprint?
It's zone 7b and I messed up. I have already espoused my corms... can I expect them to die or can I plant them in containers and leave in a well lit unheated sun room???
How do I know what color it is before the flowers appear?
And does the plant adapt to high temperatures?
Because I live in the countries of the East
Hi Danielle!🌸do you save corms from year to year like a dahlia tuber?
Hi Linda! I have never tried, but you certainly can! I will try to add another link in the description about this. I know Dahlia May Flower Farm (zone 5 I believe) digs and stores hers.
@@NorthlawnFlowerFarm Thanks!💕
Question, I am gardening in zone 7 (Philadelphia), can i leave the corms in the soil?
I presoaked the corms but forgot to check on them for ten days. The soil and the corms have dried up. Can they still be saved?
Love you dear from pakistan Thank you for the best taeching vedio Luv u
I have ranunculus plants that I purchased in bloom. I am in zone 6 b also and wondering what I should do when they are done blooming for the season. Should I take them out of dirt, cut them down, clean them off and store them in a dark location?
Do you have a video of how/when they need to be dug back up after blooming?
What month are you planting these? Thx
Thank u for sharing! Hope this can work on Brazil.
If ranunculus are bought for Spring planting, but should be planted in the fall in your zone, can they be successfully stored until the proper planting time in fall? If so, do you have any guidance?
Do you plant them outside in March ?
Just got these beauties as a gift. Can't wait until I can plant them.
I'm in Central Florida so our humidity is outrageous lol. I appreciate your information 🌱
does anyone know what will happen if i planted ranunculus over a month ago in zone 9? i just read the info she included in the description and it said to plant in the fall. oops.
Hi there! Are you on Instagram? The Hobby Home is in 9b and has some great info on succession planting in your climate.
So what month are you planting out in the garden? I'm zone 6b as well. I also do low tunnels as well.
Thank you. But 55F doesn't sound like room temperature to me! Re: soaking water temperature. What should it be?
Do you water in after planting the pre-sprouted corms?
Great video! I will never disparage buttercups again! (Buttercups are essentially wild ranunculus-I think…?). I had great success this spring with the corms I planted; my question is whether they will return next spring. I live in zone 9b-Palm Springs-Do I need to do anything special with the corms over the long hot summer? Also, in my particular area we have not seen a frost for probably the last 10 years or so, whereas it used to be a regular thing. Does that make a difference to the corms? Should I refrigerate them?
Good information about sprouting mold watch
جميل جداً تشبة وردة الجوري 👌🏻😃
Would you keep the frost cover on all spring? When is a good time to take it off?
Hi there! I'm only using the frost cloth for temps that dip below freezing. I'll pull it back otherwise.
Hi Danielle!! Can I cut back laggy ranuculus?
In zone 6b, if you plant how you did, when do the flowers bloom?
I’ve loved these flowers for years and have never been able to find a source until now.(Eden Brothers in NC) I had no idea they were so fragile and finicky. I believe my zone is 5 (Mid-Coast of Maine) I’m terrified of killing them before I even get them in the ground. Do I dig them up before a fall freeze?
I live in texas 8b zone. What can i do ? Please help, lol!
I’m totally loving all your videos. I’m sucked in,
Should be seeding or sleeping
