Lawn Care

Apply Medina Growin’ Green or Milorganite to your lawn. Water in well approximately 30 minutes per area to begin working. These feed the soil and your lawn.

Conventionally, use a fast release (Gill Lawn & Garden 13-1-3) or slow release fertilizer (Green Diamond Supreme 21-7-14). These must be watered in order to not burn the grass.

Prevent broad leaf weeds.

Use: Weed and Grass Preventer with Dimension

Plant new grass.

Lay new sod or Bermuda seed anytime this month – plan to make time for watering!

Follow city watering guidelines.

Continue watering established lawns if we don’t have rain.

Indoor Plants

Warm temps allow you to take your indoor plants outdoors for some fresh air. Just be sure to keep them protected from the sun. Shady patios are perfect for a short stay. Wash off the dust and bring them back in nice and clean.

    When watering during periods of windy dry conditions, it’s important to water slow and deep. Be sure to watch the spray of your sprinkler and adjust accordingly with the wind

    Water all plants well after planting and regularly through the first year. Plants will begin to use more water as they grow and bloom. Outdoor potted plants dry out quickly as do hanging baskets and small annuals.


    Apply mulch around trees, flowerbeds and vegetable gardens to reduce weeds and help retain moisture. We like cypress, hardwood and pinestraw mulch. These reduce weeds well and will not float away.

    1. The gusty wind broke the newest citrus tree I planted 6 months ago. About 60% of the branches and leaves are gone. If I continue watering it do you think it will grow back or should I scrap it and buy another one and start over?

      1. I have personally seen a young citrus tree backed over by a truck, the tires did not hit it but it snapped off about 12″ above the ground with no limbs left. Saw it again 2 years later and it is a nice little tree with fruit on it.
