Permaculture planting involves growing multiple crops together, creating a diverse ecosystem that benefits all plants involved.

These companion plants provide nutrients, attract pollinators, and serve as natural pest repellents, creating a thriving environment for your sugar apple tree to grow.

Chop-and-drop is a permaculture technique that involves cutting down nutrient-rich plants and using them as mulch around your sugar apple tree.

This practice provides an organic source of nutrients for your tree, while also helping to suppress weeds and conserve soil moisture.

By incorporating chop-and-drop into your gardening practices, you can create a sustainable and efficient system for growing healthy sugar apple trees.
