If the soil is too wet, the plant's roots can become damaged and lead to root rot. On the other hand, if the soil is too dry, the leaves might start to wilt, drop, or turn brown.
Fertilization of Savastana nashii Bickn.
Savastana nashii Bickn. does not require a lot of fertilization. In the growing season, the plant can be fed with a granular balanced fertilizer every two weeks. However, it's important not to over-fertilize as it can lead to excess foliage growth and a decrease in flower production.
A diluted liquid fertilizer can also be sprayed on the leaves during the growing season to provide an instant nutrient boost.
Pruning techniques for Savastana nashii Bickn.
Pruning is not necessary for Savastana nashii Bickn. However, it can be beneficial for controlling the plant's shape and size, and for removing any dead or damaged branches.
The best time to prune Nashia is in late spring or early summer when the plant has finished flowering. Pruning should be done with clean and sharp tools to prevent any damage or tearing of the stems.
To maintain the plant's natural shape, trim back the tips of the stems, removing about one-third of the plant's growth annually.
Propagation methods for Savastana nashii Bickn.
Savastana nashii Bickn. is a rare and endangered plant species that hails from the eastern Himalayas. Due to its rareness, the propagation of this plant is essential to maintain its numbers. This plant can be propagated through various methods such as:
Seed propagation
The most commonly used method to propagate Savastana nashii Bickn. is through seed. The seeds should be collected during the fruiting season when they are mature. The seeds should be sown in well-draining soil that has been amended with organic matter. The seeds require a temperature of around 20-25°C for germination, and it can take around 20-25 days for the seeds to germinate.
Vegetative propagation
Savastana nashii Bickn. can also be propagated through vegetative methods such as stem cuttings. Select healthy stems from the parent plant and cut them into 5-8 cm long pieces. The cuttings should be planted in well-draining soil that has been amended with organic matter. Keep the soil moist, and it can take around 15-20 days for the cuttings to root.
Air layering propagation
Air layering is another method of propagation that can be used for Savastana nashii Bickn. To perform this method, select a healthy stem on the parent plant, remove the leaves on the lower side of the stem, and make a one-inch-long cut on the stem's bark. Apply some rooting hormone on the wounded portion of the stem and wrap it with moist sphagnum moss. Wrap the moss with a plastic sheet to maintain a moist environment around the moss. After 30-35 days, the roots will develop, and the cutting can be separated from the parent plant and planted in well-draining soil.
