Prepping Plants for the Greenhouse: Inspect, Prune, and Debug

Space Reality Check

Plants grow larger indoors. Allocate room for winter crops and spring seedlings.

Select Wisely

Keep only healthy, valuable, hard-to-replace, or winter-blooming plants.

Pest Patrol

• Check under young leaves and stem tips for aphids (color-matched).
• Whitefly? Discard plant.
• Aphids: blast with water, then horticultural oil/soap. Treat twice before moving in.

Prune Now

Reduces size, reveals hidden pests, stimulates vigorous growth. Skip winter-bloomers (may remove buds).

Know Their Needs

Many prefer cool temps with bright light—greenhouse perfection.
