Feeding With Fertilizer

Houseplants tend to do quite well if they live in a warm place with enough light. But being trapped in a pot means they don’t have an endless supply of nutrients to drink up.

As a plant parent, you have to make sure that your baby has enough to eat. Regular fertilizing will keep your houseplants healthy, beautiful, and growing!

When To Feed

Avoid fertilizing houseplants in the winter. Most varieties aren’t in an active stage of growth in the colder months, and feeding them can lead to a weak and leggy plant, yellow burn marks on the leaves, or worse.
