Give your Petunias a boost with Thompson & Morgan's Petunia flower fertiliser. Specifically formulated, the granules in the Thompson and Morgan petunia fertiliser are specially coated so when they are added to soils and composts they absorb moisture. The moisture breaks down the coating and gently allows the release of fertiliser over several months. This provides a constant controlled supply of nutrients to your flowers throughout the season, avoiding wastage and leaching by oversupply. Easy and quick to use, this fertiliser is suitable for beginner and experienced growers alike. All you need is one quick application to feed your petunias all season - perfect for low maintenance, hassle free gardening! How to use To be used as a compost additive when potting up young begonia plants. Mix with compost/soil at the application rate of 1 teaspoon (approx. 3g) for every litre of compost. When planting in borders add 2 teaspoons of fertiliser per planting hole. T&M Petunia Fertiliser; suppli
