Before I left last week I hand pollinated six or seven female flowers that had appeared on my muskmelon vines. All appeared to take and started getting larger and pointing downward. That was a good start. When I got back from holidays, only one appeared to be growing. It's somewhere between the size of a golf ball and tennis ball.
My muskmelons are a hybrid known as Sugar Cube. These are small sweet melons with shorter vines which are great for container growing. But my main reason for picking this one was it's tolerance to certain diseases. I've had problems with melons in the past so I figured I'd go with something mildew and wilt tolerant for a change. So far so good.
