HOW TO GROW GRAPES SUCCESSFULLY
Showcasing an RLF Crop Nutrition Program
The grape colour changing period is the key period in which to increase fruit weight, sugar content and promote fruit maturity. The colour conversion of grapes is essentially the formation and accumulation of anthocyanins in the skin – nitrogen can inhibit the formation of anthocyanins, whilst phosphorus and potassium can promote them.

Therefore, at this time it is necessary to control the application of nitrogen fertiliser and increase the application of both phosphorus and potassium. RLF has the speciality products to help growers achieve this and the following highlights a trial of RLF products on grape.

Conditions were observed on 13th April – the first fertilisation for the two fields with the same degree of growth.
The trial vines were applied with RLF PowerPK, and the Control vines used other brands of colour-changing products.

The conditions as observed on 24th April – the second fertilisation day.

The conditions observed on 29th April found that the colour conversion effect
of the RLF-treated grapes was faster and more uniform.

The conditions observed on 29th April found that the colour conversion effect of the RLF-treated grapes had completely changed colour, and could be picked and put on the market for sale.

RLF Power PK has a high content of both phosphorus and potassium. The bioactive factors work together to effectively resist the effects of bad weather and well and truly meet the demand of the vines for both these important nutrients.

It gives high-efficiency supplementation of the nutrition required for the flowering and fruit swelling stage. It improves the fruit setting rate, promotes fruit swelling, adds colour, promotes early maturity and significantly improves crop yield and quality.
