Fertilizer requirements: Dissotis thollonii Cogn. ex Büttner var. thollonii benefits from regular fertilization to encourage healthy growth and flowering. A balanced, slow-release fertilizer can be applied in the spring and summer months. Be careful not to over-fertilize as this can lead to excessive vegetative growth and reduced flowering.
Cultivation methods
Dissotis thollonii Cogn. ex Büttner var. thollonii is generally grown as an ornamental plant. It can be grown in soil or in containers.
It is a tropical plant and therefore prefers a warm and humid environment. It can be kept indoors in areas with colder climates but should be positioned near a bright, sunny window.
When planting, it is recommended to use well-draining soil and to incorporate organic matter such as compost into the soil to retain moisture. Dissotis thollonii Cogn. ex Büttner var. thollonii should be planted at the same depth it was previously growing at and then watered immediately.
Watering needs
Dissotis thollonii Cogn. ex Büttner var. thollonii requires regular watering to remain healthy. During the growing season (spring and summer), the plant should be watered regularly, ensuring the soil remains moist at all times but not waterlogged.
In winter, watering should be less frequent, with the soil being allowed to dry out slightly between waterings. However, the plant should not be allowed to dry out completely as this may cause damage to the plant.
Fertilization
Fertilization is recommended during the growing season to ensure healthy plant growth. Fertilizer should be applied every two weeks or according to package instructions.
A balanced fertilizer with a ratio of 10-10-10 is recommended for Dissotis thollonii Cogn. ex Büttner var. thollonii. If using a liquid fertilizer, it should be diluted to half strength before application.
Pruning
Pruning should be carried out to maintain the shape and size of the plant. It is recommended to prune immediately after flowering in the summer. Dissotis thollonii Cogn. ex Büttner var. thollonii can be pruned heavily, and this will encourage new growth and a bushier, more compact form.
Deadheading spent flowers will also encourage more blooms and prolong the flowering period. Any weak or damaged stems should be removed promptly to prevent disease or pest infestations.
Propagation of Dissotis thollonii Cogn. ex Büttner var. thollonii
Dissotis thollonii Cogn. ex Büttner var. thollonii is a perennial plant that belongs to the Melastomataceae family. The best way to propagate the plant is through stem cuttings or division.
Stem Cuttings
Stem cuttings are a popular propagation method for Dissotis thollonii Cogn. ex Büttner var. thollonii because the plant roots easily from stem cuttings. The best time to take stem cuttings is during the spring when the plant is actively growing.
Make sure to choose a healthy stem that is free from disease and pests. Using a clean and sharp pair of shears, cut a 6-inch-long stem from the parent plant just below a leaf node. Remove the leaves from the lower half of the stem and dip the cut end into rooting hormone.
Then, plant the stem cutting into a pot filled with well-draining soil. Water the soil lightly and place the pot in a warm and bright location. Keep the soil moist and within a few weeks, roots should begin to grow from the base of the stem cutting.
Division
An alternative propagation method for Dissotis thollonii Cogn. ex Büttner var. thollonii is division. To propagate the plant through division, you need to carefully divide the parent plant into smaller sections.
First, choose a healthy and mature plant and dig up the entire plant carefully. Gently remove the soil from the root system and use a sharp and clean knife to divide the roots into several sections. Make sure that each section has plenty of roots and a good amount of foliage.
Then, plant each section into a separate pot filled with well-draining soil. Water the soil lightly and place the pots in a warm and bright location. Keep the soil moist and within a few weeks, new growth should begin to appear on the divisions.
Propagation of Dissotis thollonii Cogn. ex Büttner var. thollonii is relatively easy and can be done by home gardeners who want to add this beautiful plant to their collection.

Common Diseases
Dissotis thollonii is also susceptible to various diseases, including leaf spots and powdery mildew. Leaf spots are dark, circular lesions that can appear on the plant's leaves. They are often caused by fungi and can be managed by removing infected leaves and ensuring good air circulation around the plant.
Powdery mildew is a fungal disease that manifests as a white, powdery coating on the plant's leaves. It can inhibit photosynthesis and cause stunted growth. To manage powdery mildew, you can use a fungicide, or simply remove infected leaves. In addition, making sure the plant has good air circulation and is not excessively watered can help prevent powdery mildew from developing.
Conclusion
Overall, managing pests and diseases for Dissotis thollonii Cogn. ex Büttner var. thollonii requires vigilance and prompt action. By monitoring your plant for signs of pests and diseases and acting quickly to manage these problems, you can help ensure that your plant remains healthy and thriving.
