First year with a garden. I've tried the square foot gardening method and have a very crammed garden😁. I've produce a few cucumbers and a few more are growing but most of my leaves are dying. Burn yellow with holes. I've found a few earwigs and have thousands of centipedes in my yard. Although I haven't noticed any centipedes in the garden. I haven't used any chemicals and have sprayed neem oil in the garden. It's been hot and sunny in northwest Indiana for a few weeks now and I try to water every few day unless we get rain. Any advice will be great.
