FAQs

Do I need a trellis for Bitter Melon?

Yes—vertical support improves airflow, keeps fruits clean and straight, and simplifies harvesting. A sturdy 5–7 ft trellis or fence works well.

Can I grow Bitter Melon in cooler climates?

Start seeds indoors 3–4 weeks before the last frost and transplant once nights stay warm. Using black mulch and row cover helps early growth.

When should I harvest?

Pick at 6–10 inches while fruits are firm and uniformly green. Overripe fruits turn yellow and develop stronger bitterness.

How many plants do I need?

Two to three plants usually supply a household when grown on a trellis, with staggered harvests over the season.
