  1. Check all newly planted material for water every day.
  2. Check pots, containers and hanging baskets often as they dry out quickly and need more water.
  3. Apply mulch as needed to help conserve moisture.
  4. Make arrangements for someone to water if leaving for more than 2 days, especially with new plants.
  5. 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.

      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.
