Water in well (approximately 30 minutes per area).

Eliminate broadleaf weeds

Treat with Ortho Weed B Gon for Southern Lawns for broadleaf weeds, Image for grassy weeds and sticker burrs.

Water lawn 2 days prior to application.

Water

Only water every 7 to 14 days if we don’t get rain.
Water deeply (1”per area.)
It’s best to water in the morning. This helps to reduce problems with fungus.

Set your sprinkler:

For best lawn health in clay soil, sprinklers should be run for short times but repeated several times in the same morning, so water can soak in before more water is added. Water deep to train roots to go deep.

Pro Tips for Houseplants

  • If your houseplant looks unhappy, think location first. It may need to be moved to a different spot with different lighting.
  • Keep them away from the AC vents (they like humidity and the AC dries them out)
  • General rule for watering; water well then re-water once the soil feels dry to the touch
  • Spring is time to start fertilizing your houseplants. Your plants will love organic Hasta Gro
  • If they are getting too big for their pots, bump up to a slightly larger pot. Watch video

Water

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.

Mulch

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.
