Generally in most circumstances Nara Native Turf will perform fantastically, but sometimes, pH, soil type and other problems can arise and cause a lawn to thin out. With Nara remedying a problem like this is far easier than most lawn types.
Nara is a Zoysia macrantha has a natural habitat near sand dunes, which means it is used to being covered by sand (although it does also naturally occur in heavier soils as well). For this reason it responds extremely well to top dressing, often better than other grass types. Compared to japonica type stolons, the stolons of macrantha have less shoots at the base of the stolon and are generally found higher up, this gives it an advantage when top dressed.
When top-dressing Nara use a mix that is high in organics, with little sand or sandy loam added. Do not use a straight sandy loam mix, as a mix with higher organics will benefit the lawn for years to come. The best time to top-dress is in spring, but summer or early autumn would also be OK. We would advise that you do not top-dress in mid to late autumn or at any time through winter.
1. Spread the top dressing so the tips of the leaves just poke through, some leaves should be seen. Generally this would be a depth of 7mm to 12mm of top dressing, depending of the thickness of the lawn. For 100 square meters you will require 0.7of a cubic meter for a 7mm thickness and for a thickness of 12mm, you will require 1.2 cubic metres of organic top dressing material.
2. Rake it in with the back of a rake or a level-lawn.
3. It is also recommended to use a slow release fertiliser at the same time - depending on the time of year we suggest either our Summer/Autumn blend or our Spring blend slow release fertilisers (Click here for more information on fertilising)
4. It is recommended to water every second day for the first week after top dressing, then after that twice per week until the lawn looks lush again. It may take between 2 and 4 weeks for the lawn to look great again.
2 years ago this process was carried out on a Nara Native lawn that was in extremely poor soil, and it came back looking amazing and still looks amazing today.
So if you ever find your lawn not responding to general maintenance the way it should, try this simple trick that will keep your lawn looking great for years to come and you will be thankful you did.
