Botanical Name: Cucumis melo
Days to Maturity: 80–90 days
Native: Africa, Asia, Austraila, West Pacific Islands
Hardiness: Frost-sensitive annual
Plant Dimensions: 3'–6' vines
Variety Information: 'Ha Ogen' is a Galia (also called Gallicum) type of melon, with vigorous vines producing approximately six, very sweet and juicy 5", 3–5 pound melons with smooth yellow skin, green sutures, and no netting. The flesh is pale green with a salmon-colored ring around the seed cavity. Galia types are resistant to splitting during wet weather and "slip" off the vine like muskmelons (what we usually call cantaloupes).
When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°–90°F.
When to Start Inside: Recommended for short-season areas. 2 to 4 weeks before transplanting within 2 weeks after your average last frost date. Sow into biodegradable pots that can be directly planted in the ground; roots are sensitive to disturbance.
Days to Emerge: 5–10 days
Seed Depth: ¼"
Seed Spacing: 2–3 seeds per mound
Row Spacing: 4'–6' apart
Thinning: Thin to 1 plant per mound
Harvesting: Harvesting at the right time is very important with melons. Commercial growers harvest before melons are ripe, forcing them to ripen off the vine, but the last few days of ripening on the vine put a lot of sugars into the melon; so melons taste significantly better when vine ripened. How do you know when 'Ha Ogen' melons are ripe? A ripe melon will have a pleasant, fruity aroma at the blossom end; and a crack will form on the stem right near the point of attachment (this is called the "slip stage"). In a few days, the melon will detach from the vine with little effort and pressure. If it is somewhat difficult to detach the fruit from the vine, the melon is not ready yet. Do not allow to over-ripen.
