The weather is starting to change, but it has been mostly sunny and dry — and we’re not out of the woods yet. Our water supply remains below normal for this time of year. While upcoming fall storms will help, we need consistent rainfall to fully refill our reservoirs.
With shorter days and cooler temperatures, plants and soil aren’t drying out as quickly, and plants generally need less water now. But the ground is still dry, and some plants may still be stressed from the summer heat. New plantings will continue to need a little extra care.
Until the anticipated fall rains return in full, it’s important to use water wisely — for both people and fish. If you’re still watering your plants, here’s how you can make the most of every drop as we head into a new season:
Smart watering tips for September
- Water early or late in the day. Water before 9 am or after 7 pm. If you water during the hottest part of the day, the sun will make the water disappear faster and the plants’ roots won’t absorb as much moisture.
- Water deeply, but not frequently. Instead of giving your plants a little water every day, give them a deep soak once a week (about 1/2 inch). This encourages deeper root growth and healthier plants.
- Mulch to keep moisture. Think of mulch (like arborist woodchips) as a blanket for your soil. It keeps water in, keeps the roots cool, and helps stop weeds from growing. Add or replenish a 2-4-inch layer of mulch on bare soil.
- Check soil moisture before watering. Before you water, stick a tool like a screwdriver in the soil. Does it move through it easily? Then your plants don’t need more water. Watering too much can actually hurt your plants! Let the soil dry out between waterings.
Fall is the best time to plant
If you’re thinking of planting new trees, shrubs, or perennials, fall is the best time to do it. The soil is still warm, the sun is less intense, and the seasonal rains (once they start) do most of the watering for you.
Planting now means healthier, more established landscapes next summer — and greater water savings.
Every drop still counts
We’re all in this together. Until the rain returns in earnest, each gallon you save helps keep water in our rivers and lakes to sustain salmon, wildlife, and forests.
