Weed Control 101

Weeds come in all shapes and sizes and they are here to stay. They detract from your lawn and landscape areas and some weeds like crabgrass and bermuda even have the potential to take over. Knowing that weeds are found everywhere and move by wind, birds and mowers plus your next door neighbors’ lawn is a disaster is there really any hope of keeping the weeds at bay? The simple answer is yes. The reality is that one must approach weed control from numerous angles.

First of all, I like to evaluate the current condition of the landscape that I am trying to keep looking nice. Are the desirable grasses and plants healthy and are they receiving appropriate water and fertilizer? Do they receive the right amount of sunlight and are the soils suitable for growing healthy plants? Are lawns mowed at the proper height with sharp blades and trees and shrubs pruned properly? Poor cultural practices can foil good intentions. Secondly, I inventory the existing weeds and properly identify them. Proper identification is crucial as well as knowing their life cycle. Not all weeds are created equal and unfortunately there is not one weed control product that controls all weeds in all situations.

Once I know my site and potential threats I develop a plan. Culturally, I want to be sure the lawn is being mowed regularly at the proper height. Low mowing heights favor weeds as more light can penetrate the canopy favoring weed germination. Sprinklers and timersshould be checked for coverage and adequate timing. Fertilization should be done regularly to supply good nutrition. Good sanitation means that new soils or plants brought in should be from a reputable source and free of visible weeds. You could easily add new weed problems unintentionally. Finally, weeds should not be allowed to go to seed as one plant can reproduce rapidly left unchecked.

Prevention is the preferred approach to weed control as compared to eradication. I would include a pre emergent herbicide program to prevent weed invasion of annual weeds such as crabgrass and spurge. Proper rates and timing are critical to the success when using a pre emergent. They do not stop seeds from germinating, but do keep seeds from becoming a new plant through root or shoot inhibition. They do not control existing weeds so timing must be prior to the seeds germinating. Other weeds may already be established or are perennials. Proper identification of the unwanted weed will be essential and help determine which selective post emergent herbicide to choose. Generally speaking there are broadleaf weed, grassy weed, and sedge control products. The products vary in their effectiveness on specific weeds within each grouping. Like weeds, not all herbicides are equal.

Landscapes using good cultural methods plus an effective herbicide program can really keep lawn and flowerbed weeds reasonably in check. If you have more questions about managing weeds check out our website at Fresno.WeedManUSA.com or call 559-266-1624 or check us on Facebook.

Three Ways to Save 30% or More on Your Water Usage This Year

Okay, so we are experiencing a drought. Our rainy season is not over so there is still some hope, but either way we should be doing all that we can to conserve water. It is precious. I want to propose that we can easily save 30 to 50% on our water usage and still have a green healthy lawn and landscape. I know some of you have made up your mind that you are just going to let the lawn go dry which is a big mistake for countless reasons. (Cost to replace, loss of benefits of turf such as cooling, filtering, noise abatement, home value, aesthetics). It should not be all or nothing. There are great solutions below.

Damaged riser

First I would start with the sprinklers. Today there are much more efficient heads that will in themselves save 20-30% by providing more uniform coverage and a slower precipitation rate greatly reducing runoff. Toro and Hunter offer some really good upgrades to your old and inefficient heads. Along with this we always recommend regularly checking your system for leaks, coverage, plugged nozzles and the like which offers additional water savings.

Secondly I would replace or enhance the traditional sprinkler control box to make it a “smarter” clock. There are smart clocks with a weather station or with satellite input that can self-adjust to the weather outside and adjust daily to the needs of the landscape. A cheaper alternative is adding a device that feeds a normal controller historical data and adjusts daily and seasonally so you are not watering the same day after day throughout the spring, summer, and fall regardless of the demand. These steps can easily save 30% or more, too.

Irritrol Climate Logic

Finally I would strongly consider the use of quality long-term soil surfactants in the landscape. They will increase the water use efficiency 30% or more by improving water movement into the soil and distribution in the profile. Runoff will be greatly reduced and the soil’s ability to hold more water will significantly increase as well. Assuming there is adequate coverage, localized dry spots will disappear and the plants will find more water throughout the root zone. One treatment can enhance water management up to 4 months. Imagine saving 20-50% on your water bill and doing your part in water conservation and still having a great lawn and healthy plants!

Water is indeed very precious and so is your outdoor landscape. Taking on one, two, or all three of these steps will save water and your investment.

A Few Thoughts on Water Conservation

Kris Horvath

Let’s all pray for rain in the valley and abundant snow in the Sierras in the upcoming weeks. Water is a precious commodity that we can’t afford to waste and can’t live without. I don’t claim to be fount of all knowledge on irrigation, but I can recommend a few things one can do to be more efficient in the use of their irrigation water in the landscape. I love lawns and so I am not inclined to always jump at the idea of removing turf from the family landscape. Actually, I would be looking for ways to keep my lawn and landscape healthy with the properamount of water at the proper interval to encourage deep irrigation and deep healthy roots.

Three areas come to mind and one of them is planting the correct plant material for the right soil, exposure, climate, etc. Beyond that, I think one is crazy not to look into smart clocks (irrigation controllers) and more precision delivery from the newer emitters. You can make your controllers “smarter” with these clocks that take into account the soil texture, zip code, daily temperature, rainfall, slope, plant material and so on. The addition of a local mini weather station or internet-based weather input will allow the amount of time needed to run each valve to be adjusted up or down each cycle. This will go a long way to increasing efficiency (possibly 30-40%) over the common method of turning the clock on in March and turning it off in late October with no regard as to the actual needs of the plants.

Finally, there is the choice of irrigation emitters themselves. There are nozzles like the MP Rotators and Precision Series Nozzles that are much more efficient in both their uniformity of coverage and the rate of delivery. With a larger droplet size and slower rate of delivery one can greatly increase the uniformity and significantly reduce the chance of runoff.  

Check with your local irrigation supply house and see what advances have been made in the past few years or call Aqua Man Irrigation Solutions at 559-475-7777. Upgrades will pay for themselves in your water bill, your plant’s health, and conserve water. It’s the smart thing to do.

Crabgrass Prevention Now!

I really r..e..a..l..y don’t like crabgrass. Crabgrass is a pesky annual grassy weed that loves irrigated lawns here in the Central Valley. It gets really large and very apparent in lawns by mid-summer, but by then it is much more difficult to control. Left unchecked, crabgrass can rapidly take over a nice lawn in a matter of a few years.

Here’s the problem. You will not find an effective product for controlling existing crabgrass or dallisgrass on your store or nursery shelf. MSMA, found in Weed Hoe and Trimec Plus, is no longer available to homeowners and was the only product that actually worked on the removal of unwanted crabgrass unlike the products offered now. There are several products now on the market for homeowners for post-control of crabgrass and all contain quinclorac. I have not had good success at all in the Central Valley of California getting any significant control using these. Maybe you will be lucky and make one of them work, but my guess is that they won’t and you will be out both the time and expense you have invested.

Prevention is the key to crabgrass management especially without a reliable product for managing actively growing crabgrass plants. Ideally, a pre emergent herbicide should be applied at the proper rate prior to Valentine’s Day. There are a number of products out there (some better), but unless they are applied before seed germination at the right rate and uniformly the results could be less than desirable. Weed Man actually applies three applications to ensure better results.

What is the future for crabgrass control? There are some products in development for professional use only. As of today, there are very limited options even for the professional. New products are not as user-friendly as they are specific for warm or cool season grasses and not both. A sharp knife works well, too unless you have hundreds or thousands of plants.

Why risk your lawn to crabgrass invasion when the cheapest and most effective solution is prevention with pre emergent herbicides. A pre emergent must be applied before seeds start to germinate. Correct timing and rates of a quality pre emergent ensure great results. Have your lawn treated either by yourself or a professional before Valentine’s Day.

Please Turn Down the Water

We are settling in to our cool, damp days of winter here in the Central Valley. This means that plants will not require much if any supplemental watering from our irrigation system. Our demand for water is in the 5-10% range of what is needed to hydrate our lawns and other plantings in the peak summer months. With a normal rain shower here and there the sprinklers could even be turned off until February or March. The exceptions may be the newly planted annuals, and even they won’t need much water in winter months.

Water is precious and we certainly don’t need to waste it. Too much water can increase disease incidence on the lawn and accelerate root rots in trees and shrubs. Saturated lawns also get rutted up with heavy mowers crossing it. Weeds, of course, will love the abundance of water. A bermudagrass lawn will certainly do fine with no irrigation until you water in your preemergent crabgrass control products in February.

Here is the bottom line. Only water as needed. If you are willing to turn off your water, do so and then watch for dry spots following long periods of no rain and above normal temperatures.  If you don’t do that, then please reduce your water to one day a week and cut that to 50% or less than normal.

Let’s pray for a wet winter and tons of snow in the mountains.

To Seed, or Not to Overseed, That is the Question

It’s hard to believe, but cold weather and dormant bermuda lawns are right around the corner. The lawn will lose its color and turn a light tan color as the frost kicks in. Is that good or bad?

The real question is whether or not to overseed the lawn to mask this brown look. Obviously if you hate the look of a dormant lawn you would lean towards overseeding to have a green lawn year-round, but here are a few reasons not to overseed. It’s nice to have a few months off from mowing. Secondly, bermuda will not have to compete next spring and early summer with an aggressive ryegrass lawn for space. Bermuda will green up faster and fill in quicker without ryegrass. The use of pre-emergents will help reduce invasion of winter annual weeds to help keep a uniformly clean, brown lawn and need to go down September-October.

Overseeding your lawn in early October can give you a beautiful, green lawn this winter. It is especially a smart option when facing a mixed stand lawn or patch stand of grasses. This will help hide and even the uniformity of the lawn. As the trees grow larger and produce more shade, the bermuda lawns start thinning out and the ryegrass can provide some much needed cover in those areas. On the negative side, overseeding results in mowing the lawn for 3-4 months a year that could have been avoided had you not seeded. Once you start the overseeding process it is difficult to stop in future years as portions of the ryegrass will remain from the previous season through seed or just persistence. The non-overseeded year will often be a mostly brown lawn with numerous clumps of rye. Also, as stated above, the bermuda stand itself may be thinned somewhat due to the persistent and aggressive nature of ryegrass.

If the scales tip in favor of overseeding your lawn, you must then choose the right seed. Without going into all the various improved varieties and their features I will sum it all up by saying DO NOT OVERSEED WITH ANNUAL RYEGRASS. It is a low quality grass used in erosion control and pastures. It grows quickly, its coarse textured, yellow-green in color, and prone to winter diseases. Perennial ryegrass vastly excels annual rye in all categories. Be sure to buy a clean, high quality seed without weedy grass contaminants. Please check the seed bag tags. 

As for me, I overseed my common bermuda front lawn for the neighbors, but I also love that clean, dormant hybrid bermuda in the back that gives me a break for 4 months.

30 Days to a Better Lawn in 2014

Step outside and take a good look at your lawn. Do you see bare spots or patches of undesirable looking grasses and weeds? Maybe your kids’ activities, your dog’s constant pacing in the same path day after day, or your parking the car on the front lawn has caused the lawn to thin out due to wear and compaction. It’s true that the 19 straight days of temperatures exceeding 100 degrees certainly did not help our cool-season lawns either. The lawns are beat and just looking for some tender care.

Cooler temperatures are just around the corner. What is left of the lawn will perk up and appreciate the cool nights and shorter, milder days. Crabgrass will stop germinating by mid to late September. Thirty days from now life will be great!

What needs to be done in the next 30 days to have a better lawn for next year? Get ready because this is where you come into the mix. Check for unwanted grasses. Patches of Bermuda or dallisgrass are hard to kill and should be sprayed 2-3 times in the starting early September. Dense sections of crabgrass or bentgrass are fairly easy to kill and could wait until the middle of September to spray. If you think the lawn looks bad now just wait to see what it looks like in a few weeks!

Here’s the good news. Oct 1-10 is a great time to reseed all those problem areas. I would strongly recommend scalping down the areas to be reseeded prior to seeding followed by a fall lawn aeration to loosen the soil and encourage better root development. Areas could then be raked or dethatched mechanically to make a proper seed bed. Select a quality grass to match your existing lawn and follow suggested seeding directions. Generally tall fescue and ryegrass go down around 7-10 lbs/1000 sq ft. Next apply a ¼ inch of clean humus or compost to cover the seed to keep in the warmth and moisture to insure good germination. Apply a starter fertilizer like 10-20-10 at 10 lbs/1000. Water 2-3 times a day lightly to keep the mulch and seed moist for the first 7-14 days.

Here is what you don’t want to do. 1). Nothing. Your lawn will be no better next year and likely worse. 2). Sprinkle some seed over the bare spots and hope for the best. This is not much better than option 1. 3). Buy the cheapest seed you can find like annual ryegrass. This will result in the ugliest lawn on your block. Annual rye never really greens up, it grows very fast and often clumpy, and it does not match any grasses in your lawn. and it often gets riddled with disease in the winter months.

The window of opportunity is here. Now get outside and take the actions needed for a better lawn in 2014!
