If we plan to use drip irrigation in the future, lay it out before planting, then plant the seedlings next to the emitters. Trying to snake a soaker around full-grown squash and tomato plants was not the best practice.
Consider setting up some kind of small rain barrel or cistern or any kind of bucket-with-a-hose-fitting-on-the-bottom to feed drip lines. We can’t collect much rainwater without a roof and gutters, but we can fill a container from the hose and let it drain out slowly through drip lines to plants that like even moisture, like tomatoes.
