Got Moss?

Getting alot of calls concerning the amount of moss currently present in the lawns in early 2019. Why do I have so much moss? Do I need lime? What should we do?

1. Moss needs surface moisture to thrive. The amount of rainfall during January and February 2019 is pretty staggering compared to normal. We also haven't had very many "frozen soil weeks this winter. Moss will show up in low light, poorly draining soil areas. Until the surface can dry out for extended periods = more than a day or too, moss will continue to dominate the above environment.

2. Lime - the only time lime will generally be needed to change the soil ph to discourage moss and encourage turf is where moss is actively growing in full sun conditions during dry weather. 99% of the moss we see now are low light, poorly draining areas.

3. What can we do? Once the deluge of rain stops and soil surface can dry, there are herbicides that can effectively control moss without harming turf. If those are used during the wet, cool conditions we have now, new moss will regrow rapidly to replace killed moss. Therefore, that would be wasting the herbicide and not making an improvement in the moss control.

Let us know in ealry April if you have significant moss areas that need addressing. Remember, moss is basically a symptom of wet soil surface. Improving drainage and providing more sunlight are key to long term successful control of moss. Improved drainage + increase sun + moss control herbicide are the combinations needed to reduce moss invasion!

Wild Violet control 2019

For many years controlling wild violets in residential Turfgrass has been extremely difficult. The reason control is so difficult  is the underground structure is very Woody in nature and extremely difficult for herbicides to basically finish the control. Even herbicides like Roundup, that advertise "killing plant's roots in all" , very often would take multiple applications and still not completely destroy the underground tuber. About 10 years ago, there was a herbicide called Confront, that was pretty effective in controlling violets with about two applications. That herbicide was removed from residential use and it's only allowed on golf courses. Another herbicide, Imprelis was briefly released and did an amazing job controlling violets. However, it also controlled evergreens and other fully mature trees. It was completely removed from the market. In 2019, there is a new herbicide on the market, called Sure Power. The university trials have shown excellent control of wild violets and ground ivy without damaging trees. However, it can do substantial damage to cool season grasses if it is applied when the air temperatures exceed 70 degrees. Therefore, we will be applying this herbicide to cool season lawns from early February until the temperatures prevent us from doing so. This herbicide cannot be mixed with other products such as fertilizer. We are providing this application AT NO CHARGE to our customers that take the full cool season package. It will not be offered as a standalone service to non customers or customers that do not take a complete package. We are determined to end the frustration of customers who have had wild Violet issues for years. It is extremely important for existing customers to contact our office by email or phone by January 31st to get on the list! Looking forward to a great 2019!
