The two GroGreen Feed & Shine products have been developed and refined through several years of plant nursery trials in the UK. From 2017-2019 they were tested thoroughly against conventional chemical applications and, where possible, other similar product performance in replicated pot plant trials.

Whilst the GroGreen product range is manufactured in the UK, the novel products have been developed by the Danish company E. Marker A/S that develops and manufactures environmentally friendly and ecologically sustainable product ranges for turf, amenity and retail horticulture.
The GroGreen Feed & Shine Roses products has had increasing sales in several Scandinavian countries over the last few years and the newly introduced GroGreen Feed & Shine Buxus is now also in popular demand since its launch in 2019.
