Planting Techniques 🌳

The best time to plant is in early spring or fall, allowing the tree to establish itself. When planting, ensure the depth matches that of the nursery container to support healthy root development.

Watering Requirements πŸ’§

After planting, give your tree a deep watering to help it settle in. During dry spells, maintain a weekly watering schedule to keep the soil consistently moist.

Fertilizing Schedule 🌾

Fertilize in early spring with a balanced fertilizer to kickstart growth. Opt for a slow-release, balanced NPK formula to provide nutrients over time.
