Using organic mulch, such as leaves, straw, or wood chips, around your atemoya tree can help promote healthy growth and fruit production.

Chop-and-drop is a permaculture technique that involves cutting down nutrient-rich plants and using them as mulch around your atemoya tree. This helps return nutrients to the soil and supports a thriving environment for your tree.

Some popular companion plants for atemoya trees include pigeon pea, cassava, and Mexican sunflower.

These plants can provide nitrogen-fixing benefits and act as a natural mulch when incorporated into a chop-and-drop system.

3. Organic Natural Scraps

Another effective method to provide additional nutrients to your atemoya tree is by using organic natural scraps, such as kitchen waste and compost.

Composting fruit peels, vegetable scraps, and other organic materials creates nutrient-rich compost that can be added to your tree’s planting site, improving soil fertility and promoting tree growth.
