Tippy- sorry, I hadn’t logged on for a few days. The good news about Crimson Sweet is that it is much more forgiving than Orange Glo in terms of when it can be picked. It has a considerably longer window that it is good. If you err on it, I’d try to err on the side of giving it too much time rather than too little. That is because once it gets ripe, it will stay at peak or near peak condition for as much as 10 days or even 2 weeks! While I’ve already said I’m not sure counting days is a viable method, if other signs indicate ripeness then yes, I think 100 days is about right…at least it is for me down here in KY/TN. Someone is likely to remind us that the official harvest time for CS is 85 days and certainly a CS may be ripe in 85 days. But it also may not, and since it holds its ripeness quite a while, I think you’d have a good chance at 100 days. But again, the whole day counting makes me nervous because there are so many things that can change the length of time it takes a melon to ripen. I’ve had them ripe in about 85 and in 105.
BTW, in my experience you should not count the days you started the seeds in doors, or at least only give those days “partial credit”. No matter how big you get them inside or how early you start them, in my experience the clock really doesn’t start until they are planted outside, in the sun.
As usual, I wish there were better ways to tell folks how to know when to pick a melon. As you are finding out it is tricky, but you are learning and over time you’ll be able to spot a ripe melon, but even then you won’t be able to tell someone else how to do so. ha! Good luck!
