Spring Plant Care FAQ

When should I start fertilizing plants in spring?

Restart fertilizer when you see active new growth. Use a diluted dose first, then increase only if the plant responds well.

Should every plant be repotted in spring?

No. Repot plants that are root-bound, drying too quickly, unstable, or sitting in depleted soil. Healthy plants can often wait.

How do I move plants into brighter spring light?

Increase exposure gradually over one to two weeks so leaves do not scorch after low winter light.
