When diluted in water it creates a rich brown plant food that contains all the energy and nutrients to encourage great crops of not just tomatoes, but sweet peppers and aubergines too. Most summer veg will be in the bags for several weeks, so you’ll need to feed them. Add controlled-release feed before you plant by mixing it into the compost where you have cut holes, or add a liquid feed twice a week once the first fruits have formed. Follow the dosage and frequency advice on the bottle. Can also be used for courgette, potato, pepper and aubergine. For pepper and aubergine. Only feed when plants are actively growing, and first feeding not before two weeks after planting. Cautions Before testing, we send four secret shoppers to buy all our grow bags in garden centres, DIY stores or online. They buy two of each, making a total of eight of each brand, to see if there is any variation in the quality of each bag. It is perfect for feeding gro-bags, giant planters and tomatoes growing in the ground and is also ideal for all flowering and fruiting plants. This includes all fruiting vegetables (aubergines, peppers, cucumbers), ornamentals and all pot plants and because the nutrient balance is high in potash, this rich plant food is also recommended to encourage decorative plants into stronger and richer flowering and higher yields of other tasty fruit and vegetables.
