You can use a slow-release fertilizer or a liquid fertilizer every two to three weeks. However, be careful not to overfertilize, as this can harm the plant.
Pruning
Cassia comosa (E.Mey.) Vogel var. lanata Steyaert does not require much pruning, but you can remove any dead or damaged branches to keep the plant in good health. You can also shape the plant by removing any long or straggly branches. Prune the plant in the fall or winter, after the blooming season has ended.
Propagation of Cassia comosa (E.Mey.) Vogel var. lanata Steyaert
Cassia comosa (E.Mey.) Vogel var. lanata Steyaert can be propagated by different methods such as seed, cuttings, budding, and grafting, among others. The choice of propagation method may depend on various factors such as the availability of materials, equipment, and expertise, as well as the desired number of plants, their quality, and genetic variability.
Seed propagation
One of the most common ways to propagate Cassia comosa (E.Mey.) Vogel var. lanata Steyaert is through the use of seeds. Seeds can be obtained from mature fruits that are collected from the mother plant and dried in the sun until they split open. The seeds are then separated from the fruit, cleaned, and stored in a cool, dry place until they are ready to be sown.
The optimal time for sowing seeds is during the rainy season, when the soil is moist and warm, and there is enough light for germination. The seeds can be sown directly in the field or in containers filled with a mixture of loam and sand or any other suitable potting mix. The seeds should be covered with a thin layer of soil and watered regularly to provide the necessary moisture for germination.
Cutting propagation
Cutting propagation is another method that can be used to propagate Cassia comosa (E.Mey.) Vogel var. lanata Steyaert. It involves taking a stem cutting from the mother plant and planting it in a well-prepared rooting medium such as sand, vermiculite, or a mixture of peat and perlite.
The cutting should be about 10-15 cm long and should be taken from a healthy, disease-free stem. The leaves on the lower part of the cutting should be removed, and the remaining leaves should be pruned to reduce transpiration. The cutting should be placed in the rooting medium up to half of its length and watered regularly to keep the soil moist. The cutting should take root in a few weeks and can be transplanted to a larger container or directly in the field.
Budding and grafting
Budding and grafting are advanced propagation techniques that involve joining two plants together to create a new plant. They are typically used for Cassia comosa (E.Mey.) Vogel var. lanata Steyaert when a desirable cultivar needs to be propagated or when the plant is difficult to root from cuttings or seeds.
In budding, a bud from the mother plant is inserted into a notch or T-shaped cut made in the stem of a stock plant. The bud is then wrapped with a plastic strip or tape to hold it in place until it grows and forms a new shoot.
In grafting, a scion from the mother plant is joined with a rootstock of another closely related species such as Cassia spectabilis. The two plants are aligned and secured with a grafting tape until they grow together into a single plant.
Both budding and grafting require specialized skills and equipment and are usually done by experienced growers or horticulturists.

Common Diseases
Root rot: Root rot is a common fungal disease that affects the roots of many plants, including woolly senna. This disease occurs when the soil is saturated with water for an extended period, which leads to poor drainage and root damage. Symptoms of root rot include yellowing leaves, wilting, and stunted growth. To manage root rot, it is essential to avoid overwatering the plant and maintain proper drainage. Additionally, you can treat the plant with a fungicide to control the spread of the disease.
Leaf spot: Leaf spot is a fungal disease that affects the leaves of the woolly senna. The disease is characterized by the appearance of small, dark spots on the leaves, which can coalesce and cause the leaves to drop prematurely. To manage leaf spot, prune and dispose of infected leaves, avoid overhead watering, and apply a fungicide to control the spread of the disease.
Common Pests
Spider mites: Spider mites are one of the most common pests that affect woolly senna. These tiny pests are difficult to detect but can cause significant damage to the plant by sucking the sap out of the leaves. Symptoms of spider mite infestation include yellowing leaves, webbing, and stunted growth. To manage spider mite infestation, spray the plant with a high-pressure water jet to knock off the mites, and apply an acaricide to control the spread of the pest.
Mealybugs: Mealybugs are another common pest that affects woolly senna. These pests are characterized by their cotton-like appearance and can infest the leaves, stems, and flowers of the plant. Symptoms of mealybug infestation include leaf drop, stunted growth, and distorted leaves. To manage mealybug infestation, prune and dispose of infected plant parts, apply rubbing alcohol to the infected areas, or spray the plant with insecticidal soap.
