In the past few years this product has become so popular some gardeners simply couldn't image being without it! The high phosphate level along with various vital micronutrients, effectively stimulates root growth so it sees widespread usage as a transplant solution. Although roses and strawberries are specifically targeted, raspberries respond rambunctiously too. In fact, most container plants, fruiting shrubs and perennials will be revitalized by it. To boost blossom and fruit production, mix 15g per 5 liters of water and apply as a foliar feed every 2 weeks or so. 5 to 7 applications per season are recommended. 'Rose and Strawberry' works well on it's own, but mixing with Liquid Fish makes really high octane plant fuel.
