It is recommended to use a balanced liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20 every two weeks during the growing season, i.e., spring and summer.
Avoid over-fertilizing the plant, which can cause the leaves to turn yellow and drop. It is recommended to follow the package instructions for the appropriate amount of fertilizer to use.
Pruning
Psychotria chalconeura (K.Schum.) E.M.A.Petit var. montana E.M.A.Petit plants require minimal pruning, but it can help to maintain a neat and tidy appearance. Regularly remove dead or damaged leaves, flowers, and stems to promote new growth and prevent the spread of disease.
Pruning can also help to control the size of the plant and promote flowering. Use sharp and sterile pruning shears to make clean cuts, and avoid cutting more than 1/3 of the plant at once.
Propagation of Psychotria chalconeura var. montana
Psychotria chalconeura var. montana, commonly known as mountain squirrel-seed, is a flowering plant species in the Rubiaceae family that is native to Bolivia, Ecuador, and Peru. It is a small tree that can grow up to 4 meters tall and has attractive yellowish-green leaves and reddish-orange fruits. If you want to grow this plant in your garden, you can propagate it through several methods, including seed, cuttings, and air layering.
Seed propagation
The easiest way to propagate Psychotria chalconeura var. montana is through seed. You can collect the seeds from ripe fruits and sow them directly in seed trays filled with well-draining soil. Cover the seeds lightly with soil, water them gently, and place the tray in a warm, bright location. Keep the soil moist but not wet, and the seeds should germinate within 3-4 weeks. Once the seedlings are big enough to handle, you can transplant them to individual pots filled with a suitable potting mix.
Cuttings propagation
Another way to propagate Psychotria chalconeura var. montana is through cuttings. Take stem cuttings from a healthy plant in the spring or summer when the plant is actively growing. Choose a stem that has at least two nodes and remove the leaves from the bottom half of the stem. Dip the cut end of the stem in rooting hormone and plant it in a pot filled with well-draining soil. Water the cutting lightly, cover the pot with a plastic bag, and place it in a bright, warm location. The cutting should root within 4-6 weeks. Once the cutting has rooted, you can transplant it to a bigger pot.
Air layering propagation
Air layering is a propagation method that involves inducing a stem to produce roots while it is still attached to the parent plant. This method is suitable for woody plants like Psychotria chalconeura var. montana. Choose a healthy stem that is about 1 cm thick and make a small incision on the stem about 10 cm from the tip. Wrap the incision with damp sphagnum moss and cover it with plastic wrap. Secure the plastic wrap in place with twine or a rubber band. Keep the moss moist, and roots will develop within a few weeks. Once the roots are well-established, cut the stem below the roots and plant it in a pot filled with a suitable potting mix.
Disease Management
Psychotria chalconeura (K.Schum.) E.M.A.Petit var. montana E.M.A.Petit is relatively resistant to diseases. However, if not cared for properly, the plant may experience some problems. Here are some of the most common diseases that may affect the plant, and how to manage them:
Leaf Spot Disease
Leaf spot disease is caused by the fungus, Cercospora. Symptoms of the disease include the appearance of small, dark circular spots on the plant's leaves. The spots may coalesce, causing the leaves to become yellow and, in severe cases, leading to defoliation.
To manage leaf spot disease, remove and destroy infected plant debris and fallen leaves. Do not overwater the plant as this will create a favorable environment for the fungus. Fungicides may also be applied to prevent further spread of the disease.
Root Rot
Root rot is caused by the fungus, Phytophthora. Overwatering or poorly drained soil can increase the likelihood of root rot. Symptoms of the disease include yellowing leaves, wilting, and stunted growth.
To manage root rot, improve soil drainage to prevent waterlogging, and avoid watering the plant excessively. Remove and destroy infected plant debris and fallen leaves. Fungicides can also be applied to prevent further spread of the disease.
Pest Management
Psychotria chalconeura (K.Schum.) E.M.A.Petit var. montana E.M.A.Petit is also relatively resistant to pests. However, the plant may be attacked by various insect pests such as:
Aphids
Aphids are tiny insects that suck sap from the plant's leaves, causing them to become yellow and distorted. To manage aphids, use a sharp stream of water to dislodge them from the plant or apply insecticidal soap.
Spider Mites
The presence of spider mites is characterized by the appearance of yellow speckling on the plant's leaves. These tiny pests also spin webs on the plant. To manage spider mites, use a sharp stream of water to dislodge them from the plant or apply an insecticidal soap. Alternately, predatory mites can be introduced to control populations.
Whiteflies
Whiteflies are tiny white insects that suck sap from the plant. They cause leaves to yellow and stunt plant growth. To manage whiteflies, apply insecticidal soap or use a vacuum cleaner to suck them from the plant.
When managing pests or diseases, always use the least toxic method as a first resort. This helps to minimize harm to the plant and the environment. Regular monitoring of the plant, encouraging proper air circulation, and maintaining good soil drainage can also help to prevent pests and diseases.
