Currently growing from seed collected from melon purchased last year. Got a late start(beginning of July) so planted seed directly in the ground(raised bed) and drip irrigation. Zone 7B, 5100 ft above sea level, humidity typically 5-15%. They were slow starters but have really taken off in the last 2-3 weeks. I have several melons bigger than my fist. I see multiple others coming along…..melon growth rate appears fast…..almost feel like I can see perceivable growth every day.
