Cultivation Methods
Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña is a plant that thrives in well-drained soil, high temperatures, and abundant sunlight. It is best grown outdoors, in a garden, or in a container on a balcony or patio. To cultivate this plant, start by selecting a site with full sun exposure and well-draining soil. Prepare the soil by digging holes slightly deeper and wider than the root ball of the plant. Mix in compost or other organic matter to improve soil quality. After transplanting the seedlings, keep the soil moist but not wet. Water newly transplanted seedlings twice a week until they establish themselves and start to grow. After that, the plant requires less frequent watering.Watering Needs
Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña requires moderate watering during the growing period. This plant thrives in well-draining soil, so it is crucial not to overwater. Water the plant deeply once or twice a week. When watering, ensure that the soil is well-draining and the water reaches the roots. Avoid wetting the leaves. If there is water standing in the pot after watering, drain it off to prevent waterlogging.Fertilization
Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña requires occasional fertilization to promote healthy growth. Once a month, apply a slow-release fertilizer to the soil around the base of the plant. Nitrogen-rich fertilizers can encourage the growth of leaves, but they may interfere with flower and fruit development. Therefore, it is best to use a fertilizer with balanced nutrients.Pruning
Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña requires minimal pruning. The plant has a natural shrubby shape and does not require much shaping or pruning.

Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña can be propagated through several methods, including seed propagation, stem cutting propagation, and root division propagation.
Seed Propagation
Seeds of Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña can be sown directly into the soil or started indoors. For indoor sowing, the seeds can be planted in seed trays or pots filled with well-draining soil, kept moist, and placed in a warm and bright area. Germination can take place within 2 to 4 weeks. After plants have developed enough leaves, they can be transplanted to the desired location.
Stem Cutting Propagation
Stem cutting propagation is a reliable method for Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña. Cuttings can be taken during the growing season, usually in spring or early summer. Cuttings should be about 10 to 15 cm long and be taken from healthy plants. Remove any leaves from the lower half of the cutting and dip the cut end in rooting hormone powder. Plant the cutting in a well-draining potting mix and keep it moist. Within a few weeks, roots should start to develop, and the cutting will begin to grow.
Root Division Propagation
Dicoma anomala Sond. subsp. gerrardii (Harv. ex F.C.Wilson) S.Ortíz & Rodr.Oubiña can be propagated through root division, which is best done in spring or early fall. This method involves digging up the plant and separating the roots into multiple sections, each containing a portion of the stem and some roots. Replant each section into a well-draining soil mix and water it well. Keep the new plants moist and in bright light, but avoid direct sunlight until the plant has fully established itself.
Disease Management:
Dicoma anomala Sond. subsp. gerrardii is a hardy plant that is not usually affected by many diseases. However, the plant may still be susceptible to some fungal and bacterial diseases such as leaf spot, powdery mildew, and rust.
To manage these diseases, it is essential to keep the plant healthy and well-maintained. This can be achieved through proper watering, fertilization, and pruning. Additionally, using a fungicide or bactericide may be necessary if the disease has already affected the plant. Regularly inspecting the plant for any signs of disease is also crucial in preventing the spread of the disease.
Pest Management:
Dicoma anomala Sond. subsp. gerrardii is a relatively pest-resistant plant, but it can still be affected by some pests such as aphids, spider mites, and thrips.
To manage these pests, it is important to keep the plant healthy and stress-free. This can be achieved by regularly inspecting the plant and removing any damaged or diseased leaves. Additionally, using insecticidal soap or neem oil can help in controlling aphids, spider mites, and thrips. Using sticky traps can also help to monitor and control the population of pests.
It is important to note that chemical-based pesticides should be used as a last resort because they can harm beneficial insects and degrade the quality of the soil. Additionally, some pests have become resistant to some pesticides; therefore, it is vital to choose the right pesticide for the pest that is being controlled.
