How to Grow and Care Sea Urchin Cactus: A Complete Guide

Hello and welcome to Brainy Gardener! Today it is all about how to grow and care for Sea Urchin Cactus plants. The Echinopsis, commonly known as Sea Urchin Plant, is a species of cactus with brightly colored flowers. It is native to various regions of South America, where it gets its name from the spiny, urchin-like protrusions on the surface of many of its species. It is also sometimes called “Hedgehog Cactus” for similar reasons. The flowers are typically tall, showy, and vary wildly in color.

Summary
The Sea Urchin Plant, also know as Echinopsis, is a species of cactus with brightly colored flowers. The flowers are typically tall, showy, and vary wildly in color. They are often quite large, strikingly so, and are borne on small stalks. These gorgeous flowers set this genus apart from all the others and are also the primary reason why this plant is so highly valued among gardeners. Many species within this genus are perfect indoors plants, even as desktop plants.
1. Light and Location
Like many other succulents, Sea Urchin appreciate strong light. They appreciate a little bit of shade, but they need at least six hours of sun each day, as long as you acclimate the plant gradually to direct sunlight. A sunny windowsill will do nicely. You can even move the container outdoors if you want, but only if the nights aren’t too cold.
2. Watering and Fertilizer
Sea Urchin need to be watered in a fast-draining potting mix. In fact, you should only water them when the soil feels dry to the touch. A good way to tell if it’s time to water is to stick your finger in the soil. If it feels cool and moist, you can wait a little longer before watering. In general, a balanced fertilizer every two to four weeks in the growing season is optimal.
3. Temperature and Humidity
Most species of Sea Urchin Cactus grow best in warmer temperatures. Therefore, try to grow them in a location where the temperature will remain consistently between 65 and 80 degrees Fahrenheit. They can tolerate temperatures as low as 40 degrees Fahrenheit in winter but don’t let it get below freezing. These cacti prefer dry environments. Too much moisture can become a problem, but it rarely gets to that level.
5. Propagating Sea Urchin
Sea urchin cacti can be propagated by both offsets or cuttings. Offsets are the easiest way to propagate and likely will be the method you use most often. New offsets develop at the base of a mature plant and can easily be broken off or cut with a sharp blade. Offsets will root in the soil in three weeks if kept warm.

6. Potting and Repotting
When potting or repotting Sea Urchin Cactus, it’s important to use a soil mix that drains well. A cactus mix or an equal parts mix of potting soil, sand, and perlite should work well. It’s also essential to ensure the pot has a drainage hole, as these plants don’t like to sit in water. Sea Urchin Cactus usually needs repotting every 2 to 3 years or when the pot becomes too crowded for the plants to grow correctly.
7. Toxicity
Sea Urchin cacti are generally Non-Toxic to humans and animals.
8. Pests or Diseases
Sea Urchin Cacti are hardy plants. Generally these are disease and pest-resistant. Mealybugs and red spiders can appear sometimes. However, these instances are uncommon.

The information from Brainy Gardner was just the information I needed to grow cactus. I have had a hard time growing catus in the past, but with this information, I think I can grow them.
