A single application of Rootgrow will support a plant for its entire lifetime.
How do mycorrhizal fungi benefit plants?
In its simplest sense mycorrhizal fungi do everything plant roots do, just better.
When new plants are planted with Rootgrow it takes only 2-4 weeks under normal conditions for these fungi to start benefiting plants. In that time they attach themselves to the plant's root system and grow out rapidly into the soil, searching for nutrients and water. They essentially become part of the plant's own root system.
The benefits to plants are; Better nutrient uptake. These fungi are so much thinner and finer than the plant's own roots they can therefore find nutrients in the soil far more efficiently than the plant's own coarse roots. They are especially good at finding nutrients responsible for flowering and fruiting such as Phosphorus and Potassium. As they can explore a much greater amount of soil than the plant's own roots they are also far more likely to find trace elements and the rare nutrients that all plants need to grow well.
Mycorrhizal fungi are an essential part of a plant's ability to combat drought. Leaves and stems have developed mechanisms to combat drought such as silver leaves, waxy leaves and hairy leaves but these adaptations on their own aren't enough if the plant doesn't have its friendly fungal partner on its roots.
Mycorrhizal fungi hold onto water in soils like a sponge.
Establishment in difficult soils
Mycorrhizal fungi will enable plants to establish and thrive even in difficult soils. In poor sandy soils the mycorrhizal fungi will be able to find scarce nutrients and hold onto water. In clay soils these fungi will be able to unlock nutrients from the soil acting like a clay breaker.
How much do I need?
As a quick guideline, the amount of rootgrow needed usually works out to approximately 10% of the value of the plants purchased. i.e. spend £100 on plants and you will need 1x 360gram pouch to treat all of them.
For grass seed, you will approximately require 10 to 15 per cent of the volume (i.e. a 2.5kg bag of grass would required 250g-375g of rootgrow)
Available in a variety of sizes.
The 360g GEL variant is designed to treat bare rooted plants ONLY. Use on plants such as hedging, fruit canes, roses and trees.
It is a two step process, mixing sachet of powder to create the gel and then add rootgrow and dip roots into solution. One pouch will treat up to 150 bare root whips.
