When to harvest the Savor (charentais type) melons

To determine ripeness, examine the smallish, long-stemmed leaf attached to the vine at the same point as the fruit. At ripeness, this leaf is pale, and the fruit has a slight yellow tinge. Orange fruit rind color indicates overripeness. Johnny's Selected Seeds

None of the leaves I see are "smallish"

Charentais melons typically take 70-90 days to mature. Some companies that sell the plant recommend only allowing three melons to grow on each vine at one time to get the best fruit. Once you pick the mature fruit, the vines will produce more.

Most of the melons will only grow to the size of a softball, or about 2 pounds. Look at the color of the rind to determine if yours are ripe. They’ll take on a yellowish hue at maturity. (I threw my first ripe melon away, thinking it was rotten!) Also note that you need to remove Charentais melons from the vine – if you wait until they drop, the fruit will be overripe. Learn 2 Grow
