Growing From Seeds

Plant the Seeds- Plant the seeds to a depth of 1-2 inches in the soil, and if you plant multiple seeds, maintain a gap of 3-4 inches apart to ensure each seed gets enough space to grow properly.
Proper Watering- Once seeds are planted, water them just enough to maintain moist soil, but avoid waterlogging until seeds germinate. Once germination begins, water the seedlings regularly, especially when the climate is dry.
Transplant the Seedlings- Observe the growth of seedlings, and if you feel that they are strong enough to tolerate the shock of transplant, shift them gently to a large container or directly in the garden. However, make sure the garden has ample space for the tree to expand because it grows to a large size.

- Water the plant moderately and deeply when it is in the process of getting established. Always protect the plant from frost.
Growing From Cuttings

- Select a healthy and disease-free semi-hardwood part.
- Dip the cutting in rooting hormone to enhance the development of the root.

- Handle the planting process carefully to ensure successful establishment and to prevent damage.

Solution- Make sure the plant gets balanced light and regular feeding to provide essential nutrients.
Brown Patches
Symptoms- The discolored patches on the leaves show that there is some problem with the plant.
Reason- It is caused by fungal or bacteria infection.
