Sustainable Gardening

Sustainable Gardening

At Capital Gardens we stock a wide range of products for sustainable gardening. We aim to stock the largest selection of Organic and Sustainable gardening products in or around London, and our selection is growing all the time.

At Capital Gardens we are environmentalists, but we are also pragmatists. We believe in striving for using organic products in our gardens wherever possible, but understand that living as we do in an urban environment, balances of nature can get skewed. So to keep our plants safe and beautiful, we may need to step in from time to time with man-made products.  However, the good news is there are many products available that are naturally derived, chemical-free or biodegradable, that have a reduced impact on the environment compared to others.  We have collected these less harmful products together to form our sustainable gardening range.

As part of our commitment to sustainability, we also produce regular blog posts on organic and sustainable topics. Our aim is to provide helpful, relevant advice and inspiration for implementing organic and sustainable practices in your garden. Whether beginner or expert, we hope that you will find it a useful ongoing resource. Come and visit one of our stores to find the full range of sustainable and organic gardening products we offer.
