The distribution agreement aims to increase the number of outlets where Growing Success Organics products can be sold. In addition, the distribution agreement marks a strategic move by William Sinclair to broaden the range of "premium and environmentally sensitive" products it supplies to its customers.
The Growing Success Organics product range includes chemicals for the control of slugs,?rodents, weeds and insects and specialist gardening products. Growing Success Organics uses the 'Children and Pet Safe' symbol.
William Sinclair retail managing director Danny Adamson said: "William Sinclair and Growing Success Organics have very similar company philosophies in that we are both committed to providing customers with leading, high-quality premium brands while being conscious of the need to minimise the environmental impact of our activities.
"By applying our own efficient customer service processes to the sale of the Growing Success Organics products, we look forward to broadening the customer base and ensuring levels of customer service that are second to none.
Monro Horticulture MD Graeme Jennings said: "Working with William Sinclair was the obvious choice for us at Monro, as we believe the Growing Success Organics products are fully complementary to the William Sinclair product range.
"We are absolutely delighted at this opportunity, which will undoubtedly open doors for us, and be good for both our existing customers as well as giving us the chance to reach many new ones."
