Opuntia Humifusa Care
Size & Growth
This clump-forming cactus species is a low-growing perennial, typically growing up to 6” – 12” inches tall and 12” – 18” inches wide.
Like most other species of its genus, Opuntia features round-to-oval, flattened, and fleshy stems or pads.
The pads are green with a purple tinge and are covered with tiny reddish-brown pointed bristles, called glochids, and hair-like spines.
Flowering and Fragrance
Opuntia compressa produces striking bright yellow flowers in late spring to early summer – from May to July – at the ends of the green pads.
The flowers are large and waxy and have bushy clumps of yellow stamens in the center.
They sometimes also feature a red center.
Flowering is followed by the production of bright red fruits, which remain on the plant until the following spring.
Light & Temperature
Opuntia thrives in full sun, but can tolerate partial shade and even harsh winters.
Opuntia plants contain unique antifreeze chemicals in their cells, which makes it frost hardy to USDA hardiness zones 4b to 10b.
Watering and Feeding
Just like all other species of the cactus family, humifusa opuntia requires a low amount of water and becomes highly drought tolerant, once established.
Make sure to not overwater as the opuntia because it prefers dry soil.
Let the soil dry out between waterings in winter because if the roots will rot if they remain wet in winters.
Opuntia prickly pear cactus does not need fertilizer when it is planted outdoors.
However, it may need to be fed with a well-balanced fertilizer when grown indoors.
If the color of your indoor plant is turning from bright green to pale green and it doesn’t flower, it means your Opuntia needs fertilizer.
Soil & Transplanting
While the plant prefers sandy or gravelly soil, it can easily tolerate almost any type of soil as long as it is well-draining.
When repotting, let the soil get completely dry before taking out the plant.
Throw away the old soil and treat the cuts with a fungicide before planting it in the new pot.
Do not water plants for a few days after repotting to avoid the risk of root rot.
Grooming and Maintenance
Humifusa is an easy-to-grow and very low maintenance plant.

How To Propagate Opuntia Compressa
Opuntia prickly pear is propagated from both seeds and cuttings.
However, starting new plants from cuttings or pads is faster and easier than growing from seeds.
For collecting seeds, choose the mature fruits which are reddish-brown in color.
Let the seeds air dry for a few hours.
While the seeds could be stored, it is best to sow them in the ground, immediately after collection.
The seeds take a long time to germinate – in most cases, seedlings do not emerge until the next spring.
For propagating through cuttings, all you have to do is to break off a pad from the joint, let it dry (until its wounds heal), and simply stick in the prepared ground and it will form roots quite quickly.
Make sure the soil is dry and just like with transplanting, do not water the new cuttings until they begin to grow; watering before it can cause root rot.
