Weeds Forming Thick Mats
When you see a dense mat of foliage—like creeping buttercup or ground ivy—blocking soil airflow, root suffocation and waterlogging become real threats. Those mats also trap leaf debris and moisture, inviting fungal diseases like powdery mildew.
I counteract this by raking or lightly tilling the soil surface monthly, lifting that smothering carpet. Once the soil can breathe again, beneficial organisms repopulate, and your vegetables can access both air and water freely!
