Are there other plants I can use to replace squash in my Three Sisters garden? Some kind of colorful flower perhaps?
Yes, you can substitute other plants for squash. For instance, use other varieties of squash, like zucchini. Grow pumpkins, cucumbers, or melons (just allow more growing space). As for flowers, choose anything you like--this is your garden so feel free to let your imagination soar!

My squash plants (I have 4 that are in two separate containers) appear healthy except that the squash grow to about an inch or two and then start to rot before they fully form. It begins at the end not attached to the plant. I live in east Tennessee and it has been extremely hot and humid. What am I doing wrong? (The same thing happened last year)

Why is our squash warty looking even though it is small and hasn't been on the vine very long?
This is just due to scarring. If you have had a lot of wind lately, the scarring will become more visible. It is still perfectly safe to eat.
How can you tell the difference between male and female flowers on squash plants? Someone told me it has to do with the points on the end of the flower. Some have 4 and some have 5. Which is male and which is female? Also. which one will give squash? I have been picking my flowers, as I make a batter and then fry them in the batter. My whole family likes them this way, but I would also like to leave some on the plant to get squash. . . but don't know which flowers to leave on. Can you answer my question? I really would appreciate any information you can give me.
