Planting Tips for July

When planting indoors in July, ensure your plants receive adequate light—preferably near south-facing windows or under grow lights.

Keep humidity levels high for tropical perennials like ferns and peace lilies.

Propagation and Care

Regularly check for pests and remove any dead or yellowing leaves to promote healthy growth. Rotate plants periodically to ensure even light exposure.
