Cut back perennials that have finished blooming. They’ll look neater and many will surprise you with a second bloom when prevented from setting seed the first time.
Keep picking your vegetable gardens. By picking, you are preventing your plants from going to seed so they keep producing. If you have more vegetables than you can use, offer it to friends or call a local food pantry and ask for their drop-off days.
Replant this month for a more bountiful fall crop: green beans, peas, cucumbers, carrots, kohlrabi, summer squash, early sweet corn, green onions. Water seeded areas by hand daily until the new plants are up and a couple of inches tall. Cover the newly planted seeds with row covers to help keep them cooler and out of pecking range of birds. You can take the row covers off when the plants are several inches tall.
