Challenges of Hydroseeding under trees.

2014-05-14 09.54.27

We have no problem dragging our hose anywhere we need to go to get hydro seed where it needs to be. But there are some areas where grass just does not belong. You would not want to grow a lawn under your deck right? Not only would it be very difficult to mow but it would never get the sunlight it needs to survive. As a rule of thumb for growing a lawn if the lawn is not getting at least 3-4 hours of filtered sunlight it may be a better option to consider a better shade tolerant ground cover.

Always Green uses grass varieties that do very well in both sun and shade. We always tell our customers that our hydro seed will grow just fine in shadier areas but over time it will thin out if there is not enough sunlight. Areas that stay wet and not dry out will start to grow moss and may become more dominant than the lawn.  The only way to correct this is to thin out the trees to let more light through. Not only are there challenges with light but there is also many tree roots under ground competing with the grass roots. Your tree roots are stealing the moisture and nutrients that your lawn needs. Not only that but sometimes if it does not rain heavy enough the raindrops get caught in the canopy of the trees and never make it to the ground. Since a shaded lawn does not photosynthesize as a lawn in full sun it is not using as many nutrients so your tress are getting fed more. You can actually over feed a lawn in the shade as it can’t utilize the nutrients as quickly.

During the establishment phase there is a higher risk of erosion under trees. We use enough tacking agent to keep the hydro seed in place without washing away under most extreme rainfall conditions. Anytime you take on additional water running off flat surfaces, downspouts and water shed off of trees all bets are off. There is really no problem with a heavy rain drops falling straight down on a hydro seeded area with little to no problems. Once the rain gets collected in a tree canopy the raindrop size changes to much larger drops and come down at a more forceful rate causing certain erosion leading to spotty results. When this happens re-seeding will most likely be needed.

So if your going to hydro seed around a tree canopy make sure your getting enough sunlight for the lawn to survive. Moss is usually a good indicator there is not enough light. Have your soil pH tested, ideally it should be right around 6.5 ideally. Thin out the trees as much as possible to let more light through. Plan on over seeding  yearly with a shade tolerant seed. Be sure your lawn is getting the right amount of water using rain gauges and do not over fertilize. Understand the potential of erosion if the lawn does not get established before torrential rains.



2018 Spring Update

As of April 15th temperatures still struggle to climb for optimal germination. We have started hydro seeding with a reminder to our customers to be patient with slow germination due to the cool soil temps.
At this time we have not started any lawn renovations or new lawn construction due to inclement weather and the availability of dry topsoil. We are hoping the second half of April conditions will improve so we can get some work done. For the first half of April we have been spraying new lawns for customers that have had new septic systems installed and projects where suitable soil was prepared for us.
Always Green is a Hydro Seeding Specialist which means we only install new lawns. 90% of our work is applying hydro seed to your bare soil that was prepared by you or another contractor. 10% of our work is full lawn renovations or new lawn construction.
At this time we are only offering hydro seeding for your prepared soil. We are fully booked up this spring for the small percentage of renovation and new lawn construction work we offer.
Always Green is owner operated and our priority is to be available within a 1-3 day notice to deliver and apply hydro seed to your prepared site. You would prepare your site the same way as if you were rolling out sod with special attention to the top 1-2″ of soil being soft and loose. You should be able to poke your index finger in the soil and cover your first knuckle with ease. This will assure good seed too soil contact and an even application.
Another common question we need to clarify is (our hydro seed) needs to be applied to bare soil. It is not good practice to apply hydroseed on top of an existing lawn unless it is very sparse and there will still be good seed to soil contact.
Please call if you have any questions. I return most calls by the same evening except on holidays weekends.

Spring Soil Temperatures

With the warmer weather this February we may have an early start this spring. Hydro seeding may begin as early as the middle of March.

We ask our customers to be patient with germination in the spring while the soil temperature come back up into the 50’s. Grass seed needs soil temperature to be at least 50° for germination to start. Here is a soil temperature map for our region.

Quality does not come cheap

You are standing in front of the grass seed shelf and looking confused. There is a big difference in price. If there ever was truth to the statement “you get what you pay for” it is certainly true when buying grass seed. Cheap seed often is contaminated with seeds from the tough to control grassy weeds because they are growing in the field alongside the good grass plants when the farmer harvests the grass seed. The grass seed farmer has to decide whether to go to the extra expense of getting rid of these weeds or to sell his seed for less because of the weed seed contamination. 

Always Green pays our supplier top dollar to get weed-free seed. The better grass seed varieties also cost more because those in the know, like professional turf managers, are willing to pay more to get better varieties because they will have fewer problems. Cheap seed is going to cost you more in the long run: difficult to control weeds and grass varieties that struggle to produce a top rate lawn.

We use only the top performers on the NTEP trials. Aside from just grass seed we only use 100% wood fiber hydraulic mulch which is far superior than paper. Our fertilizer has a polyon coating making it last longer and perform better, used by prestigious golf courses. Moisture retainers will help keep your seedbed wet longer, herbicides will keep weeds away while your new lawn is growing in. These are just a few examples of why you just do not choose any company to hydroseed your dream lawn. 

Always Green has been specializing in Hydroseeding for the past 13 years. We have built our reputation on research & development and customer satisfaction.
