Enjoy salads all summer long and into fall by planting leafy greens such as lettuce, arugula, Swiss chard, radicchio, and bok choy in July and August. Many of these greens prefer a bit of shade in the hot summer months.

Battling powdery mildew? It's very common here in the PNW, but you can control it. Read more here.

Be sure you are harvesting your fruits and veggies regularly! Summer edibles will produce more if picked at least 2-3 times per week.

If you notice your leafy greens have "bolted" (put up a flower stalk with flowers) you can either pull the plant or leave the flowers for pollinators. Some leafy greens, such as arugula, will reseed themselves this way and you will have fresh plants for early fall!





Summer is a good time to fertilize your actively growing houseplants. Apply a fertilizer formulated specifically for indoor plants. Be sure to follow the directions on the product label for best results.

In summer, lawns need approximately 1" of irrigation per week to stay green and healthy!

Even if your lawn is dormant right now, you should still water about once a month to keep it from dying back completely. Also, try to stay off of dormant lawns as much as possible.
