Weeds, Leaf Loss, and Fall Planting

September is a significant transition month from hot summer to milder fall, which allows us to take advantage of another prime planting season. The air is cooling down, but the soil is still warm, creating the perfect conditions to encourage root growth before next summer hits. This month, our garden gurus are getting questions about weeds, leaf loss, and putting in new plants.


For weeds, continue to pull the young ones before they start to develop seed heads. Dispose of them in the green waste bin, not in your compost. Check that your mulch is still deep enough to stop the sun from reaching the soil. Three inches is typically a good depth.

For weeds in the lawn, we recommend keeping the lawn a little taller. Tall lawn shades soil, depriving weed seeds of light, and weed seeds can’t germinate in the dark. And tall lawn keeps irrigation in longer, encouraging a healthy root zone and strong green blades of grass.

Please bring in a sample or picture of the weeds you have to our experts in the stores. They will help identify the weed and recommend the best strategies for control.

Leaf Loss

Trees are having yellowing and dropping leaves a bit sooner than usual. Check that your irrigation is at the furthest reaches of the branches, the drip edge, and that there are enough drip emitters. The ideal spacing for drip emitters is one for every 12 inches on the ground at the drip edge.

Water restrictions often do not apply to drip, and may be run every day of the week, any hour. Check with your water provider for more information: Be Water Smart.

Typically fertilizing is not needed for landscape plants this time of year. If the plants are hungry, please stick to organic for a sustained fertilizer that won’t burn or stress your plants.

Fall Planting

Fall is the perfect time to put in new plants, and our garden gurus are here to help you find the right ones. The options are endless: bulbs, veggies, cool-season annuals, trees & shrubs, and more. As temperatures drop and the soil stays warm, new plants have time to develop larger root zones before next summer. Fall planting allows tender young trunks to get stronger, and for canopies to grow as protection for those trunks.

Our gurus remind us that sticking to drip, using mulch, and fertilizing with organics will help keep our plants healthy, successful, and beautiful—no matter what time of year we are in.
