Here's Your Annual Landscape Maintenance Plan
 

February/March

Aerate and top dress your lawn.  Use an aerator that cuts and removes a plug of soil which it places on the soil surface.  The machines can be rented or the service purchased.  Apply one half -inch of compost after the aeration.  The compost penetrates the aeration holes to bring organic material into the root zone.

It is too early to fertilize.  Wait until real grass has been mowed twice.

Apply a pre-emergent herbicide to reduce summer weeds from germinating.  This is especially important if you were bothered by sandburs and/or crabgrass. Halt, Dimension, Crabgrass Preventer, Amaze and XL are good herbicides for the job.  Note that a second application should be applied in mid-June.

To be ready for the hot weather when it arrives, call in your irrigation contractor to check out and repair your system.  Make sure the rain sensor is working and all leaks are repaired.  Have him/her instruct you how to change the watering amounts if necessary.

Have your mower sharpened and the engine tuned up.  Mow in March to keep the lawn weeds in check.

 

April

 

Mowing starts in earnest this month.  Mow St. Augustine at 3 inches tall, Bermuda at 1.5 inches, zoysia at 2 inches tall and buffalo grass at 5 inches.  Mow frequently enough that only one-third of the grass blade is removed at every mowing.  Once per week is usually sufficient.

After you have mowed real lawn two times, it is time to fertilize the lawn.  Use slow release lawn fertilizer.  The first number is the percentage of nitrogen.  Apply one pound of nitrogen per 1,000 square feet.  If the fertilizer has a 19-5-9 formula, that means about 5 pounds of fertilizer per 1,000 square feet.  The bag will tell you what rate to set the spreader to achieve the pounds of nitrogen.

Chlorotic (yellow) grass is a common symptom of St. Augustine grass.  It appears in spring when the soil is too cool for the roots to pick up iron. Chlorosis will address itself with time and a change in weather or you can apply an iron chelate product by hose-end sprayer.

May

 

Rely on the weekly watering recommendation provided by SAWS and posted weekly by email to determine how much water to apply each week. Sign up on their website even if you are not a SAWS customer.  The recommendation is based on San Antonio’s actual weather conditions and proven by over 15 years of use.

The winter weeds are trying to go to seed before the heat kills them.  Keep the lawn mowed every week to reduce production of the weed seeds for next winter.

 

June

 

Make your second application of pre-emergent herbicide to prevent sandburs

It is time to apply a soil insecticide if your lawn was attacked by grubs last year.  The same insecticide will also control chinch bugs.

 

July

 

Watering is the key.  Apply the published recommendation each week.  For especially hot areas such as along the sidewalk that seem to dry out, give them a little extra water by handheld hose.

 

August

 

Chinch bugs will make your lawn look moth eaten.  The damage usually appears on the hottest part of the lawn.  The lawn drying out will cause a similar symptom.  Hand water the spots every day for 2 or 3 days.  If the area does not green-up it is probably caused by chinch bugs.  Apply a soil insecticide.

 

September

 

Apply a pre-emergent herbicide to prevent winter weeds.  Check the label to make sure the weeds you had last year in your yard are on the label.  Rescue grass, bedstraw, dandelions, thistle, henbit and annual bluegrass are common

Discontinue watering in the evening and let the lawn go a little dry in order to prevent brown patch fungus.  If it appears anyway apply a treatment of a labeled soil fungicide.

The lawn has switched to its autumn growth mode so it is time to apply a winterizer fertilizer.  Again, apply one pound of nitrogen per 1,000 square feet.  The fertilizer will be utilized by the lawn for winter hardiness and a fast green-up in the spring.

 

November, December, January

 

Switch to a winter irrigation regime.  Water every 3 weeks if it does not rain from now until May.

You should only have to mow every few weeks to control winter weeds.

Drought Stage Information
 

Current Drought Stage - Year-round conservation measures

 

Trinity Glen Rose District Moves from STAGE 2 Drought Restrictions to Year-Round Conservation Measures

 

After considering several factors along with the rising levels in the Trinity Aquifer monitoring wells due to recent near-record rains, the Trinity Glen Rose Groundwater Conservation District (TGR) board of directors decided to move its drought stage from STAGE 2 to year-round water conservation measures in compliance with the District’s drought contingency plan.

 

“After seeing the our well levels jump due to the constant rainfall we’ve seen over the last couple of weeks, the board decided to go ahead and lift the STAGE 2 restrictions at our board meeting today rather than wait until the next meeting,” said TGR Board Chairman Joe duMenil. “With more rain in the forecast, we’re confident that the other agencies will be moving out of STAGE 2 in the near term. Despite the plentiful rain, we have seen some sprinkler systems running recently. So we want to encourage home and business owners to turn off their automatic sprinkler systems so we don’t waste water during this wet period.”

 

Year-round conservation measures include: 

1. The TGRGCD strongly encourages homeowners, homebuilders and/or developers, exempt and non-exempt well users to incorporate the conservation practices as outlined in the City Of San Antonio’s Ordinance #100322 where standards became effective January 2006. Specifically, the incorporation of the following best management practices:

       a. Rain Sensors- rain sensors should be installed and maintained on all irrigation systems equipped with automatic               irrigation controls;

       b. Xeriscape Option- Homebuilders and/or developers subdividing lots and/or constructing new single family           

           residential homes should offer a xeriscape option in any series of landscaping options offered to prospective     

           home buyers;

       c. Model Homes- Homebuilders and/or developers who construct model homes for a designated subdivision 

           should have at least one model home per subdivision landscaped according to a xeriscape design; and

       d. Rain Water Harvesting Systems- Homebuilders, developers, and homeowners should consider the installation of 

           rain harvesting systems. Rain harvesting systems can reduce reliance on common water supplies with a low cost 

           investment.

 

2. Waste is prohibited at all times. Allowing groundwater to run off into a gutter, ditch, or drain or failing to repair a controllable leak is considered waste.

 

3. Users of groundwater should use common sense and best practices to avoid water waste, practice water conservation and minimize use of groundwater for non-essential purposes.

 

4. Landscape watering with groundwater using an irrigation system, soaker hose, or sprinkler should follow guidelines in accordance with times and days as described below.

 

5. Hand watering with groundwater using a hand-held hose, drip irrigation or bucket is encouraged any time and any day.

 

6. Using groundwater for washing impervious cover such as parking lots, driveways, streets or sidewalks is discouraged and should be done responsibly to avoid runoff.

 

7. The use of commercial vehicle wash facilities that recycle water is encouraged.

 

8. Reduce groundwater consumption by any means available.

Rainwater Harvesting
 

Safety First!

Safety is always a must when working with power tools. So, we strongly recommend you wear a pair of safety glasses or some sort of eye protection during this project.

  • Tank Depot- (all size barrels); 2620 SE Loop 410, San Antonio, TX 782223 Phone - (210) 648-3866

  • Tanks A Lot - 7403 West Loop 1604, San Antonio, TX 78249; Phone - 210-393-2225

  • Son Beverage Co.; 6896 Fairgrounds Pkwy, San Antonio, TX 78229; Phone - 210-733-7761

  • Barrels by Joel - Phone # 210-717-6850 or 210-488-8025

  • Home Depot/Lowes - small barrels

  • Many on-line resources - Watch out for shipping costs!​​

 

Here are the materials you will need: 

  • A ¾” brass faucet (hose bibb)

  • 2” male PVC connectors & electrical Nut

  • Tube of silicone (bathtub)

  • Barrel​

Here are the tools you will need:

  • A battery-powered or  corded drill – 3/8 to ½ HP

  • Paddle (spade) bit, 15/16”  and 2 3/8” hole saw

  • Set of hole saws or a jigsaw  to make a 6” hole in the top

Step 1 - Drill a hole in the top of the barrel for rainwater to flow into.

Mark a spot in the top of the barrel. It doesn’t have to be the middle. Use a 6” hole saw to cut it out. Or using the bottom of a one-gallon plastic pot, mark a circle around the bottom of the pot.  Drill a ¼” hole on one side of the circle and saw the circle out.  Saw to the outside line you drew with the plastic pot.

Step 2 - Drill the overflow hole.

Using the pot as a depth gauge, mark and drill the overflow hole just beneath the depth of the pot. Use the 2 3/8” hole saw.  

Step 3 - Drill a hole for the hose bibb. 

About 3 inches up from the bottom of the barrel, drill a 15/16” hole for the 3/4” hose bibb. 

Step 4 - Install the hose bibb. 

Put a little silicone around the threads on the hose bibb, push down and screw it in.  It will be sealed when you finish. Be sure to point the hose bibb to the side for better access. About 3 inches up from the bottom of the barrel, drill a 15/16” hole for the 3/4” hose bibb. 

Step 5 - Install the overflow. 

Insert the 2” adapter with the male threads through the hole. Thread the 2” electrical nut on adapter inside of the barrel.

Step 6 - Screening out debris.

Place mosquito screen in bottom of pot & add rocks (about 2-3 inches deep) and place it in the top of the barrel.  This is the filter to keep out the large stuff off the roof. 

Step 7 - Connect your rain barrel to the downspout.

Place your rain barrel in a location where it will capture rain running off of the roof. Or, you can attach a diversion to your existing downspout that will direct water into the barrel.

Other Considerations

  • Level your barrel

  • Elevating barrels provides room for watering cans and increases gravity flow

  • If linking barrels together, place an overflow pipe on last barrel

  • Pond Pumps and transfer pumps can be used to increase flow

  • Consider placement of faucet if you live in a windy area

  • If you have children, consider anchoring your barrel to your home

Connecting two or more barrels together is easy!

1.If you want to hook two or more barrels together, use the overflow hole as the hookup between the barrels.​

2.Use a piece of 2” PVC pipe with a male-threaded connector glued to the end and screw it into the female fitting on the inside of the first barrel.  Do the same thing on the other end of the pipe and on the next barrel until all the barrels are hooked up.

3.If you do the same setup on the bottom of all the barrels, the water will empty out of all the  barrels at the same time.  PLUS, you only need one hose bibb in one barrel.
