By providing the correct growth conditions, you can ensure that your Aspidoglossum dissimile plant will grow and thrive beautifully.
Cultivation of Aspidoglossum dissimile
Aspidoglossum dissimile is a terrestrial orchid that can be grown in pots or directly in the ground. It prefers a well-drained soil mix that is rich in organic matter, such as sphagnum moss, orchid bark, and perlite.
Watering Needs
A. dissimile prefers consistently moist but not waterlogged soil. It's essential to avoid letting the soil dry out completely, as this can lead to stunted growth or death. During the growing season, it's best to water the plant about once a week or when the top inch of soil feels dry to the touch. Increase the frequency of watering during hot and dry periods, while decreasing it during the dormant season.
Fertilization
It is necessary to fertilize A. dissimile due to its high nutrient requirements. Using a balanced fertilizer with a nitrogen-phosphorus-potassium (NPK) ratio of 20-20-20 is recommended. Apply to the soil once a month during the growing season. During the winter, reduce fertilization to once every two months. Reduce the amount of fertilizer in half for plants in poor light conditions to avoid overfertilization.
Pruning
A. dissimile does not require frequent pruning, but pruning unsightly or damaged leaves and roots is necessary. Ensure that the pruning tools are sanitized to avoid the spread of diseases. After cutting damaged parts off, apply an antifungal powder on the wound. The ideal time for pruning is during the growing season. Dispose of the pruned parts safely.
