Ecofective Gardening Organic Tomato Feed Concentrate 1. 5 Litre Ecofective organic tomato feed is a high quality natural based feed, with the added bonus of DELTA+, which contains bio-stimulants to increase nutrient uptake by the plant. A universal feed for both indoor and outdoor plants, this formula is perfect to use under cover to feed tomato plants, but can also be used to feed pepper, chilli and herb plants. It makes up to 50 watering cans and promotes strong, healthy fruit and encourages abundant, vibrant tomatoes. The natural based ingredients mean it is safe to use around children, pets and beneficial insects including bees. Proven to be highly effective, the same formulation is currently used by many professional growers and landscapers across the UK and Europe.
