Q.growing luffa sponges
Hello I just came across this info on growing luffas. My plants are about 45 days old, is it too late to take off the bottom 4 branches? I have gourds growing and some of the vines are 10 long.
2nd question. I have a young sugar apple tree and found out I have to pollinate it. I have males but the females are too small.

My research says it's fine to cut the primary vine in May or June, so I'm sure this is fine.
I'm sending links to two articles that will be helpful:
