Prune
- Continue removing faded flowers from annuals and perennials to encourage new blooms.
- Faded blooms and seedpods from crape myrtles to promote additional blooming.
- Rule of thumb for fall pruning is no more than 1/3. Wait until January for heavy cutbacks.
Lawns
Apply organic Nature's Blend or Peat Moss for lawns, or conventional F-Stop granules as a preventative to brown patch fungus, which shows up as temperatures drop during fall and winter months.
Watch: Brown Patch Fungus
Apply organic Nature's Blend, Peat Moss or conventional Hi Yield Iron Plus to yellowing lawns.
Apply Nature’s Blend, Peat Moss, or Scotts Disease Ex to lawns prone to Take All Patch Fungus.
Continue to water deeply every 1 to 2 weeks if little rainfall.
Wait to apply fall fertilizer until October!
Water
- Check all newly planted material for water every day.
- Check pots, containers and hanging baskets often as they dry out quickly and need more water.
- Apply mulch as needed to help conserve moisture.
- Make arrangements for someone to water if leaving for more than 2 days, especially with new plants.
- Follow City Guidelines.

Weed Control
Spray only growing weeds with Captain Jacks Deadweed Brew or Horticultural Vinegar. These products kill all vegetation; so protect plants from drift or over spray.
Apply organic Corn Gluten meal, or Weed and Grass Stopper with Dimension in the fall and spring to prevent seeds from sprouting. It will not control already growing weeds.
Weed B Gon or Image can be applied once we cool down into the 80’s temps. An organic option is Captain Jack’s Lawn Weed Brew.

They are one of the best sources we have to pollinate our fruits, vegetables, flowers, and shrubs.
Lisa says
We put down the Medina growing green as well as back to nature right before all the rain started. Do we need to re fertilize?
James Gill says
Both of those products are organic and slow release, so some nutrient is likely still in the soil. But I would still apply a fertilizer for fall, maybe around October 1st.
