Propagation Methods
The following are the most commonly used propagation methods for Geophila repens:
Propagation via Seeds
Seeds are collected from the plant after the fruit has ripened. The seeds are then cleaned, dried, and stored in a cool, dry place until they are ready to be planted.
To initiate germination, the seeds are soaked in water for 24 hours before planting. The seeds are then planted in a well-draining soil mixture at a depth of about 1/4 inch. The soil should be kept moist but not waterlogged. Germination typically occurs within 2-3 weeks.
Propagation via Division
Geophila repens can also be propagated through division. This method is typically used to propagate mature plants that have become too large or dense.
To propagate via division, the plant is carefully dug up and the roots are gently separated into smaller clumps. Each clump should have several stems and a good root system. The clumps are then replanted in a well-draining soil mixture, ensuring that the top of the root ball is level with the soil surface. Water the plant thoroughly after planting.
Division can be carried out in the spring or fall.
Propagation via Stem Cuttings
Stem cuttings can be used to propagate Geophila repens. This method is typically used to propagate young plants.
To propagate via stem cuttings, take a stem cutting that is at least 4 inches long and has a few leaves. Remove the bottom leaves and dip the cut end in rooting hormone. The cutting is then planted in a well-draining soil mixture and kept moist but not waterlogged. The cutting should root within 3-4 weeks.
Disease Management
Geophila repens is generally a healthy plant but like any other, it can be affected by some diseases.
Fungal Diseases
Fungal infections can cause significant damage to Geophila repens. Leaf and stem spots, root rot, and powdery mildew are some of the most common fungal diseases that affect the plant. To manage fungal diseases, the affected parts should be removed and destroyed immediately, and avoid overhead watering. The plant should also be kept in well-drained soil and provided with proper air circulation.
Viral Diseases
Viral diseases are not very common in Geophila repens. They can cause mottled leaves, stunted growth, and distorted foliage. It is essential to keep the plant healthy and stress-free to prevent viral infections, as there is no cure once infected.
Pest Management
Root-Knot Nematodes
One of the most common pests that affect Geophila repens is the root-knot nematodes. They are microscopic worms that live in the soil and result in yellow, stunted plants. To manage nematodes, it is essential to keep the soil moist, but not waterlogged. It is advisable to plant other crops that can break the soil, inhibit nematode reproduction, and reduce their population.
Aphids
Aphids can also attack Geophila repens, causing yellowing, stunted growth, and leaf deformation. To manage aphids, the plant can be sprayed with insecticidal soap or neem oil. Using companion plants that attract beneficial insects can control aphids.
Spider mites
Spider mites can also affect Geophila repens, especially in dry conditions. Planting in well-drained soil, adequate watering, and increasing the humidity around the plant can deter spider mites from the area. Treatment can involve using insecticidal soap or neem oil.
