I think my 25 pounders take about 55 days. I'm recording as we speak. Wrote down when I pollinated the first one and it took on May 11. That melon is now 8 inches by 4 inches and might be ripe by the 4th of July.

Yours should be about 45 days I'd guess. How big are they now? Are you sure they're set? Usually only about 10% set. The rest get about an inch long and quit growing.

I was going to say 6 weeks. That's about what mine were in the past, let's say I live in Z5, which would be a little cooler, so your's might be a bit faster.

First off, let me start off by expressing a bit of outrage and jealousy about anyone who is fussing about watermelon fertilization on May 22.... I planted my "just-sprouted" watermeon seeds in the garden a day or two ago.

That said, I looked up my garden records from last year for "Yellow Doll" watermelon, which yields watermelons about the same size as Sugar Baby... I noted on August 12 that the melons were ping-pong ball size so that's when I assumed pollination was successsful, then the first ripe melon was picked Sept. 16, or 5 weeks later.

Mid July to Early August
