Seaweed
SEAWEED solutions like Maxicrop and Vitax liquid seaweed can help prevent and cure nutrient deficiencies in most plants – often they can be applied as a foliar feed, sprayed onto the leaves and taken up by the leaves. Heavy use of liquid feed in grow bag tomatoes can prevent magnesium uptake by the plants, and nutrients can be locked out by deep rooting plants in high pH soils. A foliar feed of liquid seaweed will rectify both. Popular fertilisers, like Tomorite and Empathy, are now available with added seaweed extract, so you have the benefits of seaweed at the same time as a fertiliser application.
