While the dill will protect the tomatoes and peppers, be prepared to transplant if the dill gets too big and tall..,
or find someone with a wheelbarrow full of cukes for pickling.
Also, the dill makes for an interesting condiment for cream cheese and many appetizers.
Call it gardening multi-tasking !!
I have a LOT of cucumbers coming in....I bought some dill seed which I am going to sow in a day or two.
