Lawn Care


Organic fertilizers such as Milorganite and Medina Growin Green are excellent fertilizers that feed plants and soil and are the best choice during hot, dry periods.

Lay new Sod

Lay new sod anytime, and Bermuda seed anytime this month.

Fix Yellow Spots

Apply organic Nature’s Blend, or conventional Hi Yield Iron Plus to yellow spots in lawn.


Mow as required. Keep St. Augustine cut to about 3”, Bermuda at 1”– 2”.

Feed your houseplants to keep them healthy and looking their best. Hasta Gro works wonders. So does Plant Tone. And Worm Castings provide an amazing boost for houseplants too!

Houseplants that are happy & healthy will produce baby plants that are easily removed and transplanted to another container. A great way to increase your collection and share with your friends.

Water-wise Gardening


Mulch all landscape areas with at least 2-4 inches of shredded mulch.

Adjust Mowing

Cut your grass higher so it will not dry out as quickly.

Trimming & Cleanup

Trim overgrown plants with excessive foliage so they use less water.
Remove old or unsightly plants you plan to get rid of anyway.
Repot root bound patio plants.

Adjust Irrigation System

Use your irrigation system or sprinklers once a week. You can water anytime before 10:00am or after 6:00pm. Use the Cycle Soak Method found on our website. Be sure not to let water run off onto the streets and sidewalks.


Top dress lawns with Nature Blend.
Use organic fertilizers to keep plants healthy.


Install drip irrigation around your foundation and plants for slow soaking and less water waste.

You can water anytime with a hand held hose, soaker hose or drip irrigation hose provided it is equipped with a positive shut off nozzle.

  1. Just had a great visit in your garden center on Airline. Your employee WYatt was most helpful with ALL my questions and very informative with products to use . Thanks again

  2. I loved your blog and thanks for publishing this!! I am really happy to come across this exceptionally well written content regarding July garden tips . Thanks for sharing and look for more in future!!

  3. What can we do for our Valencia orange we bought from you this Spring where some leaves on the ends of the branches are curling?

    1. Hi Ann – this is most likely a watering issue. A young citrus tree will need a good soaking 2-3 times per week. Keep it mulched well (2-3″ deep) to help retain moisture and to keep grass from growing up to it. If the leaves are also discolored, it would be good to bring us a sample so we can investigate further.

    2. Ann, James Gill here, and I want to add, if the orange tree is planted with the top of the rootball any lower than the surrounding ground, and especially if there was any soil placed on top of the rootball, you need to carefully replant higher. Not saying this is for sure your problem, but it is very common to plant too deep. There should be nothing but an inch of mulch on top of the rootball next to the trunk, and 2″-3″ farther away from the trunk. As Jesse said, do not let the grass grow up to the trunk, keep a 3 ft. minimum area clear of grass and just mulched. And with no rain and very hot temperatures, new plants will need water more than one day a week through the first summer.

  4. I know someone who has a rabbit and says the rabbit poop is great for fertilizing and does not need to be composted. What are your thoughts on this for veggie gardens – both in-ground and raised beds. Thanks!

  5. Thank you for sharing. All your garden tips are very helpful especially during these hot summer days. I’m always looking for new ideas. Thanks again

    1. Hi Jeanette – a light pruning up to shape, or cutting off spent bloom pods would be fine. Just make sure you trim up from the bottom, not down from the top.
