Fertilisers - Granular and Liquid
These fertilisers are used in the Annual Programmes.
Quick, easy and effective - thatch reducing - no scarifying
Here you can buy fertilisers as required rather than a complete programme. Useful if you need to top up or just buy part of a programme.
For the best results, please use as recommended. It is important to use the Spring and Autumn Biogran for thatch breakdown and either granular or liquid summer fertilisers from May until August.
Tailor made fertilisers
These fertilisers are not "off the shelf". They are made specifically to my analysis for you and the quantities of nutrient in the bag can be changed to suit your lawns. For example, a bag of the Summer fertiliser has 12% Nitrogen, if you want stronger growth during the summer, this can be changed to 14% and if you want less growth, to 10%. This means that you can control the nutrition levels very easily. I would leave the Spring/Autumn as it is and alter the summer fetiliser which is effective in the main playing season. You can make this selection when ordering.
How the fertiliser works
The granular fertilisers are all 1mm-2mm mini granules. The Spring/Autumn Biogran fertiliser contains a broad spectrum of bacteria and mycorrhizal fungi which encourage the breakdown of thatch into usable nutrients within the root zone. Results across many croquet clubs show that thatch is reduced by about 30% per annum until an ideal level of 5 to 8mm is reached. At this point the breakdown of thatch equals the production of thatch and therefore stays in balance. This system is in line with the Sports Turf Research Institute article "Do Not Disturb" and eliminates the need to remove thatch mechanically by scarification which is damaging to fine grasses.
Magnesium oxide is also included in the fertiliser to promote photosynthesis and plant health. The Mycorrhizae attach to the grassroots and grow long invisible hyphae into the surrounding soil. As a result of photosynthesis, the grass provides a constant supply of carbohydrates to the fungi. In exchange, the fungi provide minerals and moisture to the grass. It is a partnership made in heaven because the fungal hyphae are much longer and finer than the roots and have a much higher absorptive capacity.
The Summer granular fertiliser has an organic base and releases nutrients over an eight week period. The fertiliser is converted into usable nutrition for the plants by bacterial action. When favourable growing conditions exist (warm and moist), the bacteria are more active thus providing increased nutrients in sympathy with plant demand. The slow release is accomplished by incorporating longer, more complex molecules which take bacteria longer to break down.
The summer liquid fertilisers contain Humates which are derived from humus and promote an active soil biology, helping thatch breakdown and healthy growth.
I prefer to apply fertiliser late in the day as morning dew will help to dissipate the granules. If possible apply before rain is expected. Do not apply fertiliser if the grass is stressed (drought). The fertiliser is not toxic to humans, pets or wildlife and the croquet lawn can be used immediately after application.
If your lawns are used during the winter, it is a good idea to fertilise with a low input of Granular Nitrogen in November and February. Using too much nitrogen will damage the grass. The reason is that the plant cells are like balloons. Nitrogen causes the cell to expand but the cell wall requires photosynthesis to thicken. When daylight is in short supply, too much nitrogen will cause the cells to burst thus damaging the plant and inviting disease and fungal attack. The granular winter feed that I recommend has low nitrogen but 8% iron which hardens the grass and helps to control moss. In winter, Liquid Fertiliser is lower cost and should be sprayed in Oct, Nov, Feb and Mar.
Delivery costs are calculated in the cart. Delivery of up to 8 items costs less if delivered by FedX to a home address. In this case any bags are boxed for easy handling.
9 items or more are delivered by pallet, usually to the Club. When the pallet reaches your local hub, the carrier will contact you to arrange a convenient day for delivery. You can also ask for the driver to phone half an hour before arrival.
