September Tips for nw gardeners


It's Fall Sale time! Spruce up your garden with newly-arrived trees, shrubs, and perennials now that the weather is cooling and rain is on the way!

Perennials add color and texture to the garden for years, and many are great at attracting pollinators! Try these 7 plants to bring pollinators to your garden.

Beginning in late August through mid-October, you can lift and separate spring-flowering perennials and bulbs, and plant more! Our selection of spring- and summer-flowering bulbs is in now.





There's still plenty of time to plant fall/winter veggie starts. Plant lettuce and other greens for continual harvest through the first frost. Broccoli, Brussels sprouts & cauliflower can be planted now to overwinter for spring harvest! Learn more about fall planting.

Battling powdery mildew? Although it is very common here in the Pacific Northwest, you can keep it under control. Read Controlling Powdery Mildew on the blog for more info.



Don't mow still-dormant sections of lawn. If you are mowing green lawns, use a mid-high-to-high setting. 

Start fertilizing your lawn in early September.

Now is a good time to sharpen mower blades and tune up equipment.


Houseplant Spotlight: Succulents

Succulents are some of the most easy-going plants around and come in an amazing variety of shapes and looks. Plant in a cacti/succulent mix in a pot with drainage holes, let dry out between waterings and place in a spot with bright sunlight.
