Congratulations on your new lawn!
Here is what to expect after hydroseeding. You will notice the green color fades away within a few days. In a week to ten days you should see small, fine grass sprouts forming. Weeds may also be taking advantage of the fertile conditions, but don't worry about the weeds, they will choke out after the grass gains ground. Keep to the watering schedule. Within four weeks or 7cm of growth you will need to start mowing. Use shape blades to prevent damage while mowing. Read the following for more details.....
You can create the ideal growing conditions for your new lawn by sticking to the following care instructions:
Allow the GreenPatch mixture to dry for 12-24 hours. Water to keep moist. Watering too much is just as bad as not watering at all. So just keep everything moist not soaked. Depending on the season and temperature, you may have to water more frequently, 15-20 minute intervals 2-3 times a day during the germination period. The point here is to not let the mulch DRY OUT or the germinated seed will die. There are great number of timer watering heads out there at your locale hardware centers. Or better yet have an automatic sprinkler system installed prior. Either way plan ahead for your watering strategy. Don't water just before nightfall, this will introduce root diseases and molds. Regardless of the time, keep consistent in your watering and remember to water more often in hot weather and less often in cool weather to keep the area moist. After you see growth, usually in the first 10-14 days, water only once a day for a good 25-30 minutes to train the roots to go deep for their water. Then by your first mowing in 3-4 weeks water once or twice a week for 30 minutes, according to temperature.
How watering influences root disease (This is for after the germination period in the 4-5 week range) Excess watering can lead to root diseases. Staying wet in the root zone invites Pythium or other water logged diseases to attack the roots, weakening the plant. So its important to allow the soil to dry out between the irrigation cycles. Pay attention to stress from an overly dry lawn.
The initial mow should occur around the 3rd week after hydroseeding or when the grass reaches about 7cm ( 2- 3/4")in height. Be very careful during the first mowing, the fine grass can pull out of the ground by your lawnmower wheels if the ground is too wet. Do a test area first . Mowing and mowing often is important in the initial stages of the lawn’s development by helping the plant to grow outward by expanding its root zone consequently filling in any bare areas. Cut your lawn with a sharp blade. A sharp blade prevents the grass from tearing or being pulled out by the roots. Set your mower height to a higher setting, at least a 6-7cm tall, specially during the mid summer hot period, and leave the short clippings on the lawn for nutrient rich compost. If for some reason you couldn't cut your grass for awhile and it grows very tall you should consider bagging the long grass clippings. The heavier/longer clippings are slower to compost causing a thick build up of unwanted thatch. Grass height heading into winter should be short enough so not layover under snow weight which promotes snow mold. But don't scalp short, which will stress the plant. Ideally leave the height around 2 1/2 " / 6-7 cm.
Safety First - Please wear all Personal Protective Equipment; Eye protection, Gloves, and Footwear
The initial GreenPatch spray includes fertilizer so there is no need to fertilize within the first 4 weeks of your lawns development. After this initial 4-week period, you should fertilize your lawn with a slow release fertilizer. Follow the fertilizer manufacturer’s guidelines for proper application. If you have no time, or don't feel comfortable then let GreenPatch do it for you! The average cool grass cultivars in our growing zone require only 3-4 lbs of N a year. Give us a call for more information.
The GreenPatch spray mixture is weed free. However, topsoil is not. All soil contains weed seeds, which will take advantage of the new fertile conditions. Weeds germinate quicker than grass seed, but do not be concerned they will be choked out as the grass fills in. The few that might remain can be controlled and eliminated as part of your normal lawn maintenance. Ideally during your soil preparation the use of glyphosates or round up is the best method of pre-control. Do not use any strong weed control in the first 5-8 weeks.
Please Note: As of January 1, 2015 the Manitoba Government has prohibited the use of pesticides for weed control on residential lawns.
GreenPatch Hydroseeding warrants that high quality certified ingredients are used for the hydroseeding process. If the lawn does not establish properly, for up to 30 days of application, because of product or workmanship, those portions of the lawn that are not growing will be re-seeded FREE ! This is enough time for the turf to establish under normal (weather) growing conditions. Any problems must be brought to our attention within this time period so feel free to call. Greenpatch is not responsible for mechanical damage like heavy equipment or excessive foot traffic, weed competition , acts of nature, vandalism, diseases or drought , torrential rains, or other related weather conditions. If a wash out happens within the first few day we can come back to re-spray for 1/2 the cost. It is the customers responsibility to provide proper care.
Be sure to water and maintain your new lawn as directed. If the lawn is not maintained and watered as directed, the Warranty is void. This Warranty does not cover a lawn that is washed out because of heavy rain fall or burned because of over fertilizing, using the wrong fertilizer or the improper use of chemicals to kill weeds.
