- Growing edible plants in pots is easy and convenient but from time to time they will need some maintenance. Josh has three pots growing in a sunny position on his back deck that need attention. Subscribe 🔔 ab.co/GA-subscribe
First is a large pot of mixed herbs; it’s handy having a range of herbs on hand and it looks great, but inevitably some plants will dominate others over time. In this case, it’s the oregano.
Josh has already cut back the spreading oregano, and the sage and thyme have bounced back a little, but for a better long-term outcome, he will rejuvenate the whole pot and remove some of the oregano.
He digs out most of the oregano roots - these can be potted up if wanted to create new plants for friends. The sage is cut back a little and a layer of decomposed topsoil is removed so it can be replaced with fresh potting mix, plus compost and a few handfuls of pelletised manure.
As he replants, Josh then adds some extra seedlings for variety: purple and tricolour sage, winter savory and common thyme.
Finally, the mix is mulched well and the pot is watered well.
Another pot has been home to a lemongrass plant for many years. It’s been growing well but has spread to fill the whole pot, so there is probably very little potting mix left around its roots.
He chops the foliage back to reduce stress on the roots and divides the clump, removing clumps of outer roots that can be potted up separately. He trims the roots a little, teases them out and repots the main clump with fresh potting mix. A handful of pelletised manure and mulch follow, then a thorough watering.
The largest pot is home to a makrut lime, which looks great as well as providing leaves for cooking. However, repotting a small tree of this size is a bit daunting. Instead, Josh gives it a light prune each year to keep it in check, and he removes some of the soil from the top of the pot to make room for fresh potting mix. The fresh mix will have better structure, improving drainage, and fertiliser is added for extra nutrients. Some of the surface roots are lost in this process but this is a mild root prune, encouraging the plant to create new roots.
Finally, the pot is mulched and watered in with liquid kelp to reduce shock.

What brand of potting mix? Is that Eucalyptus mulch?
Can you do the same thing with a dwarf mandarine as you did with your lime?
What do you do with the old tired soil? How can it be reused and replenished?
Maybe add it compost mix?
Or add lots of organic matter to it.
You mix with your new stuff if you really want it to go further & last. Also I recommend keeping the cut herbs instead of covering them with the old soil in a bucket.
