Trouble

I have been eating tomatoes and cucumbers for quite a while now.. and they are great. I was watering every other day. When the weather got hot I had to go to every day. I would come home and find the cucumber wilted. The tomato wilted too, although to a lesser degree. Today I came home and the cuke was wilted after a single day. I decided that the soil was compacted and the water was running down the inside of the bag. I water until the space above the dirt in the bag fills with water. By that time the water is running out the opening in the bottom where the plant stems emerge. Anyway, I climbed up and the soil was very hard and compact. I worked it over with a metal probe, loosening. I then added a little fresh soil to the top. Hopefully that solves the problem.
