After germination, transplant them to a larger pot or the ground.
The plant can also be propagated vegetatively by stem cuttings, which should be taken from healthy plants with strong roots and leaves. These cuttings should be planted in a well-drained and moist potting mix and watered regularly until they establish roots.
Watering Needs for Arachis hagenbeckii Harms
Hagenbeck's groundnut requires regular watering to grow well. However, overwatering can cause the roots to rot, so it's essential to strike a balance between the two.
When planting the plant, ensure the soil is moist while avoiding waterlogging. Watering should be done regularly during the dry season, at least twice a week, and in the rainy season, reduce the frequency but don't stop watering altogether.
It is essential to check the soil's moisture content regularly by digging a small hole and feeling the soil. If the topsoil feels moist, then the plant does not need water. If it feels dry, then it's time to water the plant.
Fertilization of Arachis hagenbeckii Harms
Arachis hagenbeckii Harms requires a good supply of nutrients to produce healthy growth. The application of fertilizers can help maintain a healthy and vigorous plant.
The best way to fertilize the plant is by applying organic fertilizers such as compost, manure, or leaf mold. These materials should be applied during the planting stage and periodically after that.
You can also apply inorganic fertilizers such as nitrogen, phosphorus, and potassium in the ratio of 4:2:3. The application should be done every two weeks until the plant reaches maturity.
Pruning of Arachis hagenbeckii Harms
Pruning is essential to maintain the shape, size, and overall health of the plant. It involves removing dead, diseased, or damaged parts of the plant.
The best time to prune the plant is during the dry season when its growth slows down. You should use a sharp and sterile pruning tool to avoid damaging the plant.
During pruning, remove any dead or diseased stems, yellowing leaves, and broken branches. You can also shape the plant by cutting the side branches or twigs to achieve the desired shape.
After pruning, it is essential to apply a fungicide to the plant to protect it from fungal infections.
Propagation of Arachis hagenbeckii Harms
The propagation of Arachis hagenbeckii Harms, also known as Hagenbeck's earth-pea, can be done through various methods such as:
Seed Propagation
Seeds of the Arachis hagenbeckii Harms can be collected from mature plants. The seeds should be collected when the pod is mature and starts to dry out, turning brownish-black in color. The collected seeds should be stored in a cool and dark place in order to maintain their viability.
To propagate using seeds, use a well-draining soil mix. Plant the seeds at a depth of 2-3 cm. Keep the soil moist and in indirect sunlight. The seeds have a germination rate of 60%.
Cuttings Propagation
Arachis hagenbeckii Harms can also be propagated through cuttings. Cut a stem of a mature plant and dip it into rooting hormone powder. Then, plant the cutting in a well-draining soil mix and keep it moist in indirect sunlight. The rooting time of the cutting is between 2-3 weeks.
Division Propagation
Another method of propagation is by dividing clumps of the plant. This method can be done during the early spring or late fall when the plant is not actively growing. Gently dig out the clump and divide the plant into sections. Replant these sections into individual pots or directly into the ground.
Propagation of Arachis hagenbeckii Harms can be easily done using any of the above methods, as long as proper care and attention is given to the newly propagated plants.
