Lawn Care

Fertilize when the grass is actively growing.

Treat organically with Medina Growin’ Green or Milorganite. Organic lawn food is best for long-term root and soil health.

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.

For both post & preemergent weed control use Bonide WeedBeater Complete granules.

Water lawn 2 days prior to application.

If you treat for weeds, wait 3 weeks before you fertilize.

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 and then refrain from watering for 7 to 14 days 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
