Perennial Plants for Container Gardening
Prickly Pear (Opuntia spp.)is a cactus that’s easily propagated by setting a piece of it in the soil. It’s known for the fiesta of brightly colored flowers that appear in summer and goes well with Ice Plant (Delosperma spp.), a smaller, but equally tough succulent that forms a thick groundcover and sports daisy-like flowers.
Tips for Overwintering Perennials in Pots
Depending on rainfall you may need to water your pots into the winter months, or until the soil freezes. This means that as long as temperatures are consistently above 32 degrees F, you’ll want to check occasionally to make sure the soil isn’t dry. Feel the soil with your fingers, if the top two inches of soil feels dry to the touch, you should give the plant some water. Also, you do not want to apply fertilizer during the winter when the plants are dormant. When new growth starts emerging in the spring, you may resume routine watering and fertilization.
The soil in your planters can become compacted and depleted of nutrients over time. It’s a good idea to remove the plants from the pot every three years to replace the soil. Doing this in the spring will get them off to a good start. This is also the perfect time to divide plants if they seem overcrowded. Use the plant divisions to create new planter combinations or share with plant-loving friends and family!
