Feeds, Weeds, & Fungicides

Fertiliser & weedkiller

Fertiliser is used to improve the growth, health, yields, and flowering of plants. Plants grown in pots and containers require more regular feeding than plants in the ground. A good selection of organic and non-organic, feeds, weeds, and fungicides can be found at The Secret Garden. Please read the instructions on all products carefully before use.

Bone meal is a natural fertiliser. Plants can absorb the nutrients from bonemeal efficiently due to longer periods of release in the soil. Packed with Nitrogen to support healthy growth, Calcium for strength, and Phosphorus for a healthy root system. Bonemeal is perfect for feeding trees, shrubs, hedging, and even root veg such as potatoes. Add 135g of bonemeal to the bottom of the planting hole for new trees and shrubs. Alternatively, scatter 135g to every square metre around the border and lightly fork over the soil avoiding roots.

Growmore contains the three major nutrients for healthy plant growth in equal balance. This pelleted formula is easy to use and less attractive to foxes unlike Bonemeal or Fish, Blood, and Bone.

Home-made Garden Fertilisers

Believe it or not, you can make good fertiliser at home. Most leafy green plants can be harvested to make fertiliser but some plants make better fertiliser than others. Nettles and Compfrey make good fertilisers. You can steep the leaves in water to make a tea fertiliser. Once strained, this fertiliser will keep for around a year. You will need a well-sealed container for these as they do smell unpleasant.

Wood ash from fire pits and wood-burning stoves is also highly nutritious and easy to obtain. Worm castings and wormery tea is also good.

We encourage customers to remove weeds by hand as much as possible. Mulching in around plants with bark or strulch will help suppress weeds. Cardboard can be placed on bare soil on the allotment to prevent weeds. Most weedkillers are not good for the environment. A choice of glyphosate and glyphosate-free sprays and concentrates can be found in The Secret Garden centre.

Garden Fungicides

The Secret Garden centre has a selection of fungicides that will treat the common fungal infections in your garden such as black spots, powdery mildew, and rust. You can reduce the spread of fungal infections by removing affected leaves from around the base of the plant and the plant itself. The leaves should be disposed of in your general waste bin but not your compost bin. Affected stems can be pruned out as well. Keep plants well watered in hot weather and increase airflow around the plant by ensuring they are not planted too closely together and regular pruning of excess growth. Frequent sterilisation of your garden tools will also prevent the spread of fungal infections.
