2020 SEASONAL WATERING GUIDE

 

Practical guidelines for seasonal watering of lawns & turfgrass for 2020 

"GENERALLY, ONE SHOULD  WATER TURFGRASS DEEPLY & INFREQUENTLY"
Responding to climate conditions and plant stress to determine exact watering needs, understanding that sprinklers are to be use as a supplementary source only.


SPRINKLERS SHOULD BE A SUPPLEMENTARY SOURCE ONLY FOR WATERING LAWNS. During periods of heavy rainfall, automatic sprinkler systems should be turned off (temporarily) or the program adjusted to water "around the weather/rain". WIND is a factor also and watering should be avoided during high winds of 20mph or higher. 

Being diligent in monitoring the weather when choosing exactly when to water your lawn makes all the difference. Over-watering leads to weed problems and a shallow root system, while under-watering stresses the turfgrass and promotes an underdeveloped canopy. See our annual watering guide below to help water correctly throughout the year.


This model is based on "Rotor-Type" sprinklers 20 min = approx. ¼” of water. If you have "spray-heads" (sprinklers that do not rotate) then reduce these times by half. Optimal watering start times: 2am to 6am, concluding by 9 or 10am at the latest during the normal growing season.
___________________________________________________________________________

SPRING 70°~80° (March ~ May) 1/2" of water/wk, one water session/wk
(March & April delay start times until temperatures are above 40°)

Example: when no rain is present
All Turfgrasses: ~ 40min x 1/wk @ 6am = 1/2"/wk

EARLY SUMMER 85°~95° (June ~ July) 1" of water/wk divided into 2 or 3 watering sessions/wk.

Example: when no rain is present
Warm-season grasses (Bermuda/Zoysia): ~40min x 2/wk @ 5am = 1”/wk 
Cool-season grasses (Fescue): ~25min x 3/wk @ 6am = 1”/wk (disease warning)

LATE SUMMER 95°~110° (July ~ Aug) 1½” of water/wk divided into multiple watering sessions/wk.

Example: when no rain is present
Warm-season grasses (Bermuda/Zoysia): ~40min x 3 @ 5am = 1½”/wk, 
Cool-season grasses (Fescue): ~12min x 2/day Everyday @ 6am & 3pm = ~2”/wk

* FALL 70°~95° (Sept ~ Oct) 1” of water/wk divided into 2 watering sessions/wk.

Example: when no rain is present
All Turfgrasses: ~40min x 2/wk @ 5am = 1”/wk
* Fescue: (If Seeded) 
                 12min x 2 ED @ 6am & 3pm = 2”/wk - 1st 10 days after seeding (~Sept 1st)
                 20min x 1/day @ 7am =  1¾”/wk - next 10 days
                 35min e/o day @7am = 1½”/wk - next 10 days
                 40min x 2/wk @ 7am = 1”/wk - throughout Oct until the end of the season

November – Sprinkler systems OFF before & during freezing conditions

Top 5 Things You Can Do To Insure Good Weed Control

Top 5 Things You Can Do To Insure Good Weed Control:

1. Watering-in treatments correctly as advised on the E-Doorhanger sent to you after each treatment. Watering too little, too much or waiting too long can all compromise the weed control results. Waiting on rainfall is not recommended. Rainfall can wash away weed spray & fertilizer or worse, force the pre-emergent too deep into the rootzone of the turfgrass which can cause turf damage. Gentle irrigation is much preferred to unpredictable rainfall.

When irrigated correctly, the pre-emergent can get to the exact depth required and then dries and bonds to the soil creating a weed prevention barrier – this is how it’s done.

2. Avoid mowing with dirty/weedy mowers. Even lawn mowing services can bring in unwanted weeds. The best way is to use your own mower and don’t mow weeds with it, keep it clean & uncontaminated.

3. Turf must be healthy enough to pose natural competition to weeds. Be sure it’s not being suppressed by: Grubs/insects, lack of sunlight, soil compaction, soil infertility, poor drainage, soil movement.

4. Take what measures you can to reduce high weed pressure from surrounding areas.

5. Avoid over watering (includes rainfall) which prematurely washes away & dilutes the weed preventing active ingredients in the pre-emergent. Over watering causes weed problems like “Nut-Sedge” & “Crabgrass” & other hard to kill weeds. See our season-long water guide

Top 5 Reasons Why Your Lawn Might Be Thinning Out

  

Top 5 Reasons Why Your Lawn Might Be Thinning Out:  

You almost assuredly have at least one, if not multiple of the following things acting on your lawn.

1. Shade/Tree suppression of turfgrass – all grasses need at least some sunlight and good airflow to be healthy. Trees rob grasses of water, nutrients & sunlight.

2. Grubs - eating the root system of your grass.

3. Winter Kill - root system too shallow or not enough turf canopy cover to protect from extreme freeze (this one mainly applies to Bermuda grass).

4. Soil Infertility – A pH imbalance or lacking key nutrients like Nitrogen, Phosphorus & Potassium or other micro nutrients. We can take a soil sample and do a soil test.

5. Soil Compaction – we have mostly clay soil here in our area and it gets hard as a brick & roots cannot penetrate, core aeration & top dressing with “Rich-Mix” top soil will introduce organic matter, loosening the soil allowing it to breath.

Sifi Treatment Update


We Are Appling Our Fall Lawn Treatment Of The Sifi Program (Liquid & Dry)

Warm Season Grass (Bermuda/Zoysia):
- This treatment contains pre-emergent & weed killer to control winter & early spring weeds.
- When activated correctly, this treatment will provide weed control for 6 months. To the extent that this treatment is activated correctly, will determine the effectiveness of the weed control provided.

Cool Season Grass (Fescue):
- Received our signature slow release fertilizer with weed control.
- Any areas (that we were made aware of) that have been recently seeded already before this point, have not been treated in such a way as to prevent germination.
- It may not be possible to over-seed Fescue beyond this point until this time next year.  Please communicate with us (before Sept.) if you plan to over-seed your Fescue so we can postpone future pre-emergent applications to allow for Fescue seed germination.
- Your next treatment will be next spring approx. February.

Watering Instructions: (Based on “Rotor-Type” sprinklers 20 min = approx. ~ ¼” of water. Reduce to half that for “Spray-Heads” or “mister-type” sprinklers)
- WAIT ~24 hrs. before watering to allow the weed killer to stick & kill weeds (2hr rain fast warranty).
- THEN, water lawn to activate the pre-emergent. (wait no longer than 10 days, the sooner the better).
- Gentle irrigation is highly recommended to unpredictable rainfall for the best possible results.
- Water .50” (~40 minutes) per area with “Rotating” sprinklers (half that “20min” for stationary sprinklers).         
- Regular watering thereafter. CLICK HERE to see our complete seasonal watering guide to help you water correctly throughout the year.

Mowing: Avoid mowing until after watering in this treatment. Always use a sharp blade. Avoid excessive clippings. Do not reduce cut height of Bermuda grass, but rather allow a dense turf canopy to protect the grass roots during winter.

Sifi Treatment Update

We Are Applying Our Sifi Round #4 Treatment (Dry)

Warm Season Grass (Bermuda/Zoysia) & Cool Season Grass (Fescue):
- This treatment contains a dry fertilizer with key nutrients like Potassium & Phosphorus and is safe for Bermuda, Zoysia & Fescue grasses.  
- We also spot sprayed any lingering weeds you may have, but we can only spray what we can see. If your lawn was freshly mowed, some weeds may not have been seen/sprayed.  Some temporary turf discoloration may occur – this is normal and to be expected.  
- Your next treatment will be approx. Sept. If Fescue seeding is to be done at all this Fall (Sept.) we need to know by the end of August so we can avoid spraying pre-emergent in those areas prior to seeding.

Reduce to half that for “stationary” or “mister-type” sprinklers)
- WAIT ~24 hrs. before watering to allow the weed killer to stick & kill weeds (2hr rain fast warranty).
- THEN, water in to activate the fertilizer (wait no longer than 48 hrs). Gentle irrigation is highly recommended to unpredictable rainfall for the best possible results.
- Water .50” (~40 minutes) per area with “Rotating” sprinklers (half that “20min” for stationary sprinklers).
- Regular watering thereafter.
CLICK HERE to see our watering guide. It will help coach you on how to water throughout the year.

MOWING: 
Do not mow until this treatment has been thoroughly watered in and dried.

Sifi Treatment Update

We Are Applying Our Sifi Round #3 Treatment (Liquid& Dry)

Warm Season Grass (Bermuda/Zoysia) & Cool Season Grass (Fescue):
- This treatment is safe for Bermuda, Zoysia & Fescue grasses.
- This treatment contains weed control and fertilizer.
- No Fertilizer was applied to any Fescue grass, because Fescue is fertilized at a different time, in the fall.
- Weed killer results “might” be slower (up to 1 month) in cooler temperatures below 65°
- Minor discoloration may occur but will be removed with mowing of new growth.
- You have weed insurance, so call our WEED HOTLINE (405) 707-3054 anytime to report weeds or lawn problems throughout the year (no charge).  This helps us stay informed about your lawn.
- You get 1 free Q/A site visit consultation each year, so use it. Call John (owner) to look over your awn if you have questions or issues and let’s fix it.
- Your next treatment will be approx. July/Aug. If Fescue seeding is to be done at all this Fall (Sept.) we need to know by July 4th so we can avoid spraying pre-emergent in those areas prior to seeding.

Reduce to half that for “stationary” or “mister-type” sprinklers)
- WAIT ~48 hrs. before watering to allow the weed killer to stick & kill weeds.
- THEN, water in to activate the fertilizer (wait no longer than 48 hrs). Gentle irrigation is highly recommended to unpredictable rainfall for the best possible results.
- Water .50” (~40 minutes) per area with “Rotating” sprinklers (half that “20min” for stationary sprinklers).         
- Minimal to no watering thereafter depending on weather, wind & rainfall. Once the treatment is activated avoid any soil disruption.

- CLICK HERE to see our watering guide. It will help coach you on how to water throughout the year.

MOWING: 
Do not scalp/bag Bermuda/Zoysia grass beyond this point as it may compromise the fertilizer longevity.
