Phosphates are vital in helping root development and the quick establishment of young and recently moved plants. Vegetables, especially peas, potatoes, onions and root crops benefit from them and a regular dressing encourages the vigour and colour of outdoor bulbs and flowers. Phosphates also encourage the early maturing of fruit. ?
Superphosphate may be applied all the year round as a base dressing before sowing or planting. Sprinkle it evenly over the whole area 70g / sq m (2oz per square yard) and work into the top 10cm (4 inches) of soil with a fork or hoe. As a top dressing to established plants, sprinkle over the whole area covered by the branch spread of established bushes, trees and shrubs 70g / sq m (2oz per square yard). Hoe or rake in and, if dry, water in for maximum benefit. Do not apply as a heap at the base of the stem and shake off any that lodges on the foliage.
