It is tolerant of various weather conditions and can survive in temperatures ranging from -20°C to 40°C. The plant can be propagated using stem cuttings or seeds. Ensure that the cutting is dry before planting to reduce the risk of rotting. The plant does well in well-draining soils and requires a minimum of eight hours of sunlight daily.
Watering Needs
Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow is a drought-resistant plant, which means that it has low water needs. The plant requires watering only when the soil is completely dry. Overwatering can cause root rot and harm the plant. Ensure that you use a well-draining soil mix and a pot with sufficient drainage holes to prevent waterlogging.
Fertilization
Fertilizing Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow can be done once a month during the growing season, which is typically from the end of spring to the beginning of fall. A balanced fertilizer with an NPK ratio of 10-10-10 or 5-10-5 is recommended. Do not fertilize the plant during the dormant season.
Pruning
Pruning Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow is usually not necessary. However, if you notice any dead or damaged stems, you can remove them by cutting them close to the base of the stem using a sharp, clean pair of scissors or pruning shears.

Propagation of Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow
The propagation of Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow can be done through various methods. The most common methods include vegetative propagation and seed propagation.
Vegetative Propagation
Vegetative propagation is the most common method used for propagating Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow. This method involves taking stem cuttings from the mother plant and rooting them to form a new plant. The stem cuttings should be taken in the spring or summer when the plant is actively growing. The cuttings should be left to dry for several days before planting to allow the cut surface to heal over. Once the cuttings have healed, they can be planted directly in soil or in a well-draining potting mix.
Seed Propagation
Seed propagation is another method used for propagating Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow. This method involves collecting ripe fruit from the mother plant and removing the seeds. The seeds can be sown directly in soil or in a well-draining potting mix. It is best to plant the seeds in the spring after the last frost has passed. The seeds should be lightly covered with soil and kept moist until they germinate. Germination can take anywhere from one to four weeks.
Disease Management
Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow is generally a resilient plant, but it can be susceptible to some diseases.
Bacterial Soft Rot: This disease is caused by bacteria in the Pectobacterium and Dickeya genera. The symptoms of this disease are soft and watery tissue, which may develop a foul odor. The best management technique is to remove and destroy infected plants. Proper irrigation practices can also help to decrease the chances of infection.
Crown Gall: This is a bacterial disease caused by the bacterium Agrobacterium tumefaciens. It causes the development of galls or tumors on the stem. The best management strategy is to remove infected plants; fungicides are not effective against crown gall.
Root Rot: Root rot is caused by fungi and oomycetes that grow in soil. It can cause the rotting of the roots, which can lead to the death of the plant. This disease thrives in wet soil, so proper drainage is crucial to prevent infection. Additionally, avoid overwatering the plant.
Pest Management
Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow can be attacked by some pests. The following are some of the common pests that might affect the plant and suggestions for management.
Opuntia Stem Borer: This pest is a moth with larvae that bore into the stem. To manage this pest, you can prune the affected stems and destroy them. Biological control using nematodes can also be effective.
Spider Mites: These pests are tiny and can cause significant damage to the plant. Symptoms include the presence of spider webs and yellowing of the leaves. To manage spider mites, you can use insecticidal soaps or oils, or release predatory mites to control their population.
Opuntia Cactus Beetle: This pest is a beetle with larvae that feed on the stems of the plant. Pruning and destroying the affected stems is the best management technique. Pesticides can also be applied but should be used sparingly to avoid damage to beneficial insects.
Regular monitoring of the plant and maintaining good cultural practices can help prevent most diseases and pests from affecting Opuntia missouriensis DC. var. trichophora Engelm. & Bigelow.
