We planted using X’s cut in landscape fabric too, but we overwatered and our tomatoes seem to have root rot. We are hoping to harvest soon, but the plants are very damaged. Next year we will leave more room for air at the base of the plants and water much less!
I would stick my finger in the cuts. While other parts of the garden were dry an inch down...the soil under the fabric was nice and moist. I watered the melons very little.
