Light Requirements
Synalissa melambola thrives well under bright but filtered light conditions as it is native to the understory of tropical rainforests. However, direct sunlight can scorch the delicate foliage, leading to permanent damage or death of the plant. It can also be grown under artificial light, but it should receive at least 14 hours of light per day for optimal growth.
Temperature Requirements
The ideal temperature for growing Synalissa melambola is between 18 to 24 degrees Celsius. Temperatures below 15 degrees Celsius can lead to stunted growth, while temperatures above 28 degrees Celsius can cause the leaves to wilt and turn yellow. It is crucial to keep the temperature consistent as sudden fluctuations can shock the plant.
Soil Requirements
Synalissa melambola prefers well-draining, porous, and loamy soils with a pH between 6 to 7.5. It requires high levels of organic matter, which can be achieved by adding compost or leaf mold to the soil. It does not tolerate waterlogged conditions, so it is essential to keep the soil moist but not water-soaked. The plant is susceptible to root rot, which can quickly spread to the rest of the plant if the soil is poorly drained.
Cultivation of Synalissa melambola Tuck.
The Synalissa melambola Tuck., commonly known as Smooth Waxy Shadow Lichen, is a species of lichen that grows on trees, rocks, and soil. It is easy to cultivate and grow, making it ideal for both beginners and experts in lichen gardening.
The ideal location for cultivating Synalissa melambola Tuck. is an area with partial to complete shade and moderate levels of humidity. The lichen does not require direct sunlight, but it prefers an area with good air circulation.
The lichen can grow on a variety of substrates, including trees, rocks, and soil, but it prefers a clean surface free from pollutants and pesticides.
Watering Needs of Synalissa melambola Tuck.
The watering needs of Synalissa melambola Tuck. are minimal, as it obtains all the moisture it needs from the environment. Rainwater and morning dew are sufficient to keep the lichen hydrated; thus, manual watering is unnecessary.
Watering should be avoided when cultivating Synalissa melambola Tuck. since excess moisture may cause it to rot or develop fungal infections. If the area where the lichen grows is prone to drought, minimal misting may help to revive it.
Fertilization of Synalissa melambola Tuck.
Synalissa melambola Tuck. does not require fertilization, and adding fertilizers may be detrimental to its growth and health. If the lichen grows on a tree, it obtains the required minerals and nutrients from the tree barks. In contrast, lichens that grow on rocks or soil obtain these needs from the environment through the process of photosynthesis.
Pruning of Synalissa melambola Tuck.
Pruning is unnecessary when cultivating Synalissa melambola Tuck. The lichen is self-sufficient and does not require any maintenance practices. If any debris or pollutants settle on top of the lichen, gently brushing it off with a soft brush or blowing it away will suffice.
Propagation of Synalissa melambola Tuck.
Propagation of Synalissa melambola Tuck. can be done through two main methods: seed propagation and vegetative propagation.
Seed Propagation
Seeds of Synalissa melambola Tuck. can be collected from mature fruits. The seeds should be cleaned and stratified at 4°C for 60 to 90 days. After stratification, the seeds can be sown in a well-draining seedling mix and covered lightly with soil. The seedlings should be kept moist and placed in a warm, bright location. Germination should occur within 14 to 21 days.
Vegetative Propagation
Vegetative propagation of Synalissa melambola Tuck. can be done through stem cuttings or division.
Stem cuttings: Take stem cuttings from a mature plant in the spring or summer. Cut a section of stem that is 7-10 cm long and remove the lower leaves. Dip the cut end of the stem in rooting hormone and insert it into a well-draining rooting mix. Cover the pot or container with a clear plastic bag or dome to maintain humidity. Place the container in indirect light and keep the soil moist. The roots should form within 2 to 4 weeks.
Division: Synalissa melambola Tuck. can be propagated through division in the spring before new growth emerges. Carefully remove the plant from its container and gently separate the roots into sections. Each section should have roots and at least one stem. Plant each section in a well-draining mix and keep the soil moist. Place the container in indirect light and the roots should establish within a few weeks.
Disease Management
Synalissa melambola Tuck. is susceptible to various diseases, including foliar diseases such as powdery mildew and leaf spot, and root diseases such as root rot. Powdery mildew can be identified as a white, powdery substance on the leaves, while leaf spot shows as brown or black spots on the leaves. Root rot can be identified by the decay of the roots, often leading to wilting or stunted growth.
To manage these diseases, cultural practices such as proper watering and sanitation are crucial. Watering should be done in the morning to allow the foliage to dry during the day. Infected leaves and debris should be removed and destroyed. Fungicides can also be used to control the diseases, but their effectiveness can be limited if the cultural practices are not in place.
Pest Management
Synalissa melambola Tuck. is also prone to attacks by pests such as spider mites and scales. Spider mites are tiny and suck sap from leaves, causing yellowing and leaf drop. Scales, on the other hand, are small insects that attach themselves to the plant and suck sap, causing stunted growth and leaf yellowing.
To manage these pests, natural predators such as ladybugs and lacewings can be introduced to the garden. Oil sprays can also be effective in controlling spider mites and scales. Additionally, practicing good sanitation by removing infested plant parts and debris can also help in controlling the pests.
