I’m thinking we should plant dill on the side of the big trellis bed where we have no eggplants . . . once we get the cucumbers in . . . which will happen maybe at the end of the month to anticipate the snap peas dying and making room on the trellis. DIll and cucumbers are good companions, we have the room, and it’s great eastern swallowtail butterfly habitat!
sounds great Ansley!
