green garden

Not sure about you, but summer felt pretty short this year. You may not be ready to turn towards fall but autumn does officially arrive on September 22. Your garden may even take a little bit of time to also show signs of the turning season but this newsletter is here to help you prepare for it with information about general garden care and fruit tree tips. Mayor Franklin, along with other mayors and Governor Inslee, proclaimed September 2022 as Puget Sound Starts Here month. Throughout the month, the City of Everett will use social media to highlight how to strengthen stewardship of our shared watershed and encourage all to take action to improve the health of Puget Sound. There are so many easy ways that you can be a part of the solution to water pollution.

Garden cleanup

Congratulations – you made it through another garden growing season! It’s time to relax, enjoy the vegetable harvest, think about next year’s garden, and maybe order some new seeds.
 
But wait! Things are still happening out there. Many weeds germinate and grow all winter long in the Pacific Northwest. Mulching unused beds with leaves, compost, or wood chips will help keep them at bay and keep your soil in place during heavy rains. Watching and eliminating weeds is a year-round endeavor here. Pulling weeds from wet soil is very satisfying!

Keep watch for pests, too. Slugs and snails can be found under boards, pots, in wood piles, and anywhere there is some protection. Look for them and their eggs (pearly, opalescent, round beads in clumps) and destroy them.
 
Plants die back in the fall, fruit falls from trees, leaves pile up. It’s nice to leave seed pods on plants for the birds, but don’t leave diseased plants in the garden. Collect them, along with fallen fruit that may harbor insect pests, and dispose of them in your yard waste bin. Don’t put diseased plants or materials that may shelter insects in your backyard compost, since it doesn’t heat up enough to kill pests or disease. Leaves from your trees (and your neighbors’) make excellent mulch in garden beds. Don’t leave them on your lawn, though, where they can form a thick mat that can kill grass. You can cut back spent perennial plants but you can also leave cleanup until spring. Leaves covering the crowns of plants provide protection from frost and sturdy stems provide overwintering homes for pollinators and other beneficial insects. Remove spent plants from the vegetable garden to lessen opportunities for diseases and pests to overwinter. This is especially important for plants that are known to be susceptible to disease, such as tomatoes and potatoes (late blight is a universal problem here).
 
Roots are still growing, even if the above-ground plant is not, and they need room to grow. Avoid compacting the soil by walking on garden beds or driving on lawn areas.
 
Lawns benefit from a last clean-up mowing when they have stopped or slowed their growth in November. If you fertilize in the fall, use a slow-release fertilizer that will release nutrients gradually over the winter. Don’t overdo fertilizers or they may simply run off and add to stream pollution. Always follow instructions on the bag and avoid “weed and feed” products, which are not effective, especially  in fall and winter.
 
Take a regular walk around your yard and garden to look for problems and enjoy the seasonal landscape. Then go inside, relax, and order those seeds for next year.

usual suspects

Fruit tree pests

If your apples and pears hosted some unwelcome visitors this year, it would be a good idea to do a few things to prevent their coming back next year.
Apple scab and pear scab are fungal diseases that are encouraged by wet and warm springs like we had this year. You might have noticed watery looking spots that later turned dark on the leaves. The leaves might have been distorted. As the fruit matured, it would have been misshapen and had brown, roughened or corky spots which might have developed deep cracks. On pear, symptoms can also appear on the twigs.
The scab fungus spores overwinter in fallen tree debris. To keep scab from returning next year, rake and destroy (do not compost) fallen leaves or cover them with soil. You can also apply nitrogen to the fallen leaves to enhance decomposition.
Other unwelcome visitors are the apple maggot and the codling moth. You might have harvested apples and pears that had a tunnel in them, perhaps a rotten looking core. In many cases the entire fruit is ruined and can’t be eaten.
The females of the apple maggot and codling moth lay eggs on the young apples and the larvae eat their way into the fruit. The apple maggot doesn’t infect pears, but the codling moth does.
The larvae eat and grow inside the fruit, tunnel their way out of it and then pupate on the ground beneath the tree during the winter months.
 
Cleaning up all dropped fruit, leaves and tree debris off the ground and destroying infested fruit will help curtail these pests. Never compost the infected fruit. Another helpful action is to wrap the tree trunk with corrugated cardboard or burlap to trap migrating larvae. Then check inside the wrap every so often and remove any cocoons you find and destroy them.
WSU Extension Hortsense has great advice on how to deal with these problems and others you may encounter in your garden.

stormwater and you
rain garden

Surface water management: Why should we care?

Management of your surface water means understanding where rain and irrigation water goes when it leaves your property. It takes only 1 inch of rainfall on a 1,500 square foot roof to generate 1,000 gallons of runoff. Other impermeable surfaces such as driveways, sidewalks, sheds, patios, and decks should also be considered for measuring runoff. With a rainfall average of 32 inches a year, that would be enough water to fill 581 rain barrels.
Water runoff picks up pollutants from our property left by our tires, oil drips, garbage overflow, pet waste, fertilizers, etc. This runoff flows into our streams, and untreated, directly into the Puget Sound. Our lawns and gardens work as natural filters. The best way to protect the Sound is to keep that water on our property.
So how do we keep that water on our property? First, check all irrigation systems to be sure they are working properly, only watering gardens and lawn and only when needed. You can help moderate rain water by using any one or combination of the following “rainscaping” ideas:

  • Applying mulch and compost
  • Including berms, trench drains, or swales
  • Protecting dripline and drainage outlets
  • Checking gutters and downspouts
  • Using lawn alternatives
  • Installing permeable paving options
  • Planting native trees and shrubs
  • Using rain barrels and cisterns
  • Building a rain garden
  • Adding retaining walls and terraces

Snohomish County has a great guide to get you started on your DIY stormwater property management.

PSSH

September is Puget Sound Starts Here month

It takes just three small changes to keep pollution out of our creeks, lakes, rivers and Puget Sound. Our small actions add up to a BIG difference for Puget Sound, the Salish Sea and marine life!
 
When it rains, pollution from cars wash into storm drains, and then straight into local streams, lakes, rivers, and Puget Sound. Pollutants like oil, car wash soaps and chemicals, and bits of tire dust are bad for water quality and harm people and wildlife, like salmon and orcas, that depend on clean water to survive.

TIRE MAINTENANCE: Proper tire maintenance will extend the life of your tires and save you money.

  • Keep tires properly inflated so that they will wear down more slowly. Check your tire pressure once per month, either with your own pressure gauge or at a gas station air pump. You can find the recommended tire pressure in your owner’s manual, stamped on the tire itself, or on a sticker inside the driver’s side door.
  • Get your tire alignment checked and rotate tires according to the manufacturer’s instructions. Proper alignment and regular rotation prevent uneven wear on your tires, reducing the amount of tire particles that wear off as you drive.
  • Car tires have many chemicals that help protect them from damage. As we drive, the tires wear down, leaving tiny bits of tire behind on our roads. The chemicals in the tire bits are toxic to fish. When it rains, the runoff picks up the tire bits and carries them down storm drains and into our waterways.
Scientists recently discovered an ingredient in tires called 6PPD-Q. It’s used to preserve tire rubber, but when it reacts with ozone in the air, it transforms into a new chemical that’s highly toxic to coho salmon. Taking care of your tires is the best thing drivers can do to reduce wear and prevent tire pollution.

CAR WASHING
  • Take your car to a commercial car wash. Commercial car washes, both tunnels and bays, are required to treat their dirty wash water.
  • If using a commercial car wash isn’t an option, wash your car in a grassy area. The grass and soil will soak up the wash water, preventing it from running down the street into a storm drain.
  • When you wash your car, the rinse water contains harmful pollutants like oil, grease, heavy metals and soaps. If you wash your car on the street or in your driveway, the pollutants run on the street and into the storm drain, and then flow untreated into our local creeks, lakes, rivers and Puget Sound. That’s why in Everett it’s illegal to let that soapy water enter a storm drain.
 DON'T DRIP AND DRIVE
  • Take these steps to maintain the health of your vehicle and the environment:
  • Check your vehicle for leaks regularly and get them fixed promptly. Learn how to diagnose or fix a leak.
  • Always dispose of used motor oil properly by bringing it to your local auto shop for recycling. Call or visit 1-800-RECYCLE to find a location near you.
  • Use ground cloths or drip pans if you find a leak or are doing engine work. Clean up spills immediately.
  • Even a small oil leak can have a big impact on your car and our creeks, lakes, rivers, and Puget Sound. Every drop on your driveway means a shorter lifespan for your car. Plus, oil and other petroleum products are toxic to people, wildlife, and plants.
