Rootgrow – licensed by the Royal Horticultural Society was £9.99 now £8.99
This is the first and currently the only plant or soil treatment to be licensed by The Royal Horticultural Society. RHS Gardeners find plants treated with Rootgrow Have superior plant establishment with better natural vigour Overcome re-plant problems more successfully Have better developed root systems Are better able to cope with conditions of drought A single application of Rootgrow will support a plant for its entire lifetime. “At RHS Garden Wisley, we use rootgrow mycorrhizal fungi when planting trees and shrubs and we are now starting to use it when planting perennials. For me, using rootgrow mycorrhizal fungi has become one of the most important ingredients to ensure planting success” Colin Crosbie – Curator RHS Garden Wisley How do mycorrhizal (pronounced my-cor-y-zal) 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. Drought tolerance 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
