Gardening

How do I know whether my tomatoes are unhealthy?

How do I prevent the bottom rot on tomatoes in a pot? Is adding eggshells helpful?

Is it true that pouring a little watered milk on a tomato plant is a good idea?

And do you suggest growing marigolds with tomatoes?

Sorry if you already answered these questions, but I think these problems trouble beginning gardeners.

Our lot is maybe 53 feet by 150 including our house. We have a driveway that is too narrow to use, but there is an oleander to the side of it. I have hesitated to plant vegetables near that oleander because oleanders are poisonous. But I am keeping some other kinds of plants there. It is very sunny and ideal for growing flowers.

As I understand it, you grow flowers not far from your tomatoes and other vegetables. I think that is so important for attracting bees.
