Vitax Q4 + is based on the original all purpose fertiliser Q4. Vitax Q4+ has the added benefit of mycorrhizal fungi, helpful bacteria and a range of biostimulants to encourage root growth and help plants to establish. Q4+ contains vital plant foods for planting roses, trees and shrubs and is suitable for use in own mix compost as the mycorrhizal fungi increase nutrient uptake.
For Roses – apply at 140 g/m2 prior to planting or for established roses apply as a top dressing in late March and again in late June. Try to apply when the soil is moist or water gently and hoe in.
