Fertilization for Globulea canescens Haw.
Globulea canescens Haw. does not require fertilizer to grow. In fertile soils, it can lead to extra growth and reduced flowering. However, if the soil is nutrient deficient, using a slow-release or a balanced fertilizer will offer enough nutrients to avoid plant deficiencies. Apply the fertilizer in early spring to promote optimal growth.
Pruning for Globulea canescens Haw.
Globulea canescens Haw. does not require pruning. However, trimming away dead or faded flowers will encourage the plant to produce new blooms. Removing any leggy or straggly growth will maintain plant shape. Prune in late winter or early spring when the plant is still in dormancy.

The lower leaves should be removed from the cutting, and the cutting should be dipped in a rooting hormone. The cutting should be planted in a well-draining potting mix, and the soil should be moist. The pot should be placed in a warm, sunny location, and the cuttings should be watered regularly.
Division
Globulea canescens Haw. can also be propagated through division. This method is used to propagate mature plants that have grown too large for their current container. To propagate through division, the plant should be removed from its container, and the root ball should be separated into two or more sections.
Each section should have at least one stem and a healthy root system. The sections should be planted in a well-draining potting mix, and the soil should be moist. The pot should be placed in a warm, sunny location, and the newly divided plants should be watered regularly.

The best way to manage spider mites is by using insecticidal soaps or neem oil to spray the affected plants regularly.
The other pest that affects the Globulea canescens Haw is the whitefly. This pest weakens the plant by sucking the juices, which results in the yellowing of leaves. Severe infestations can cause the leaves to drop, leading to plant death. To manage whitefly infestations, use sticky traps or insecticidal soap applications.
Common Diseases
Globulea canescens Haw is also prone to a few diseases that could affect its growth and productivity. One susceptible disease is root rot. This disease thrives in overly wet soil conditions, causing roots to rot and eventually kill the plant. The best way to prevent root rot is by planting the shrub in a well-draining soil and avoiding overwatering the plant.
Another significant disease that Globulea canescens Haw is prone to is powdery mildew. This disease causes a white powdery substance to appear on leaves, which can make the plant unattractive and reduce its vitality. The best way to manage powdery mildew is to prune affected plant parts, improving air circulation, and use of fungicide applications.
Overall, management of pests and diseases for Globulea canescens Haw requires proper care, prompt identification of pests, and timely intervention. By observing health practices, gardeners can grow healthy and thriving Globulea canescens Haw shrubs.
