The Granular Programme
Quick, easy and effective - thatch reducing - no scarifying
This programme has 4 fertiliser applications during the summer and, optionally, two during the winter. Each taking about 10 to 15 minutes. Optional Extras can be added to the programme as explained in the "Details" tab.

The quantities for the Summer and Winter programmes are itemised below.
Summer (April to September)
1/. Croquet Lawn Spring/Autumn 6 10 14 + 3MgO BIOGRAN Granular fertiliser
2/. Croquet Lawn Summer 12 0 12 + 3 MgO 50% Slow release Organic Base
Half lawn 2 x 15kg of each fertiliser = 4 bags
Full size lawn 4 x 15kg of each fertiliser = 8 bags
Bowling Green 6 x 15kg of each fertiliser = 12 bags
Winter (October to March)
Winter Fertiliser & Moss Control with Iron 3 5 10 + 8%FE
Half lawn 2 x 15kg = 4 bags
Full size lawn 4 x 15kg = 8 bags
Bowling Green 6 x 15kg = 12 bags
Soil Conditioner W 20kg bags Two treatments are usually necessary ie Spring and Autumn and can be applied using a fertiliser spreader with a wider port setting.
Half lawn - 15kg per treatment
Full size lawn - 30kg per treatment
Bowling Green - 45 kg per treatment
Soluble Iron 25kg Moss and Fungal Disease control One bag is enough to treat a croquet lawn five times. Dilution; 5kg of crystals diluted in 50 litres of water covers one croquet lawn. For moss apply Spring and Autumn. Affected areas can be sprayed using a knapsack sprayer or a fine rose watering can.
Diluting soluble iron is quick and easy.
I use a 1 litre scoop and a paint paddle which costs £3.91 at Screwfix. Add Soluble Iron to half a bucket of cold water. Stir with the paddle for 1 minute and pour off.
DELIVERY allow 10 to 14 days (can be more at busy times) by FedX or pallet
PAYMENT Goods are supplied on credit to registered Croquet Clubs and CA members. Payment is due within 14 days of delivery by cheque or bank transfer.
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 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.
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.
Optional winter feeds.
If your lawns are used during the winter, it is a good idea to fertilise with a low input of 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.
Soil Conditioner is essential on some alkaline lawns to clean the soil and help produce a superb, smooth playing surface. If you would like to know more about the beneficial effects of this product, please phone me.
Moss produces spores twice a year so should be treated in Spring and Autumn to kill the moss and prevent new spores ripening. Moss doesn’t have a vascular system and the roots have no function except to hold onto the ground, so re-growth is caused by spores in the soil not from roots. The winter feed mentioned above will reduce the moss to some extent but is not as strong as soluble Iron. The grade of iron that I supply dissolves well even in very cold water, is widely used by professionals and works really well. One bag is enough to treat the whole lawn five times so is very cost effective, there are cheaper alternatives but Iron comes in many grades and some can be hard to dissolve and very damaging to sprayers. At the dilution that I recommend it will blacken moss and I usually leave it and let the grass grow through, that way the surface isn’t disrupted. However, you can rake lightly but try not to disturb the rootzone.
Be careful to wash your sprayer out very thoroughly so that no iron is left in the pipes or pump as it will re-crystalise and potentially ruin the sprayer. For spot treatment, a watering can and fine rose can be used.
This video shows how soluble iron can be mixed with water quickly and easily using a paint paddle (£3.91 from Screw fix).

Delivery costs are calculated in the cart. Delivery of up to 8 bags costs less if delivered by FedX to a home address. In this case the bags are boxed for easy handling.
9 bags 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.
There is no restriction on the use of Iron as a turf "hardener" or "green-up" tonic. At higher concentrations pesticide certification is required.
