How to grow gardenia

When to plant gardenia

Plant this broadleaf evergreen in spring or early fall, when the soil is warm enough for root growth but the plant is not under summer heat stress. Extension guidance favors these two windows over mid-winter for broadleaf evergreens, with early fall allowing roots to establish before the ground freezes.

Gardenia is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
