Wilt Infects Tomatoes after First Year in Raised Bed

by Bill
(Webester MA)

I have 3 raised bed planters (4' W - 16' L - 12" D)with a drip irrigation system. The drip irrigation is placed a good 12" from the base of each plant & we water daily at 4am for 15-min. In year 1 we had TREMENDOUS success. But each year after that not so good. Just when everything looks good the yellow & brown spots appear and in a week or two the plants are toast. Is there anything I can add to the soil? Please keep in mind we have dogs.

"OR"

Do I just stop planting tomatoes for a couple of years?
