Gardening Knowledge
Hand-written, practical guidance from the gardens we care for across the Chilterns. Start with the question in front of you, then make the next move with confidence.
Start with the real question
What needs attention in your garden right now?
Pick the closest concern and we will take you to a focused group of local guides. You can then search or browse without losing the thread.
Welcome to our Gardening Knowledge library
Welcome to our Gardening Knowledge section, tailored specifically for residents in the Chilterns and surrounding areas of Oxfordshire, Berkshire, Buckinghamshire, and Bedfordshire. Take your time exploring these seasonal articles, hand-written by our expert local gardeners. We created this resource to answer our clients' most frequent garden maintenance questions, and we update it regularly to keep your outdoor spaces thriving.
How CGM knowledge works
Keep the standard answer free. Add the garden-specific answer when it matters.
Our public articles remain complete, useful and searchable. The extra value is not a shortened version behind a paywall; it is the interpretation that depends on a real garden, its history and the result you are trying to achieve.
Use the five-minute assessment for a responsible starting route, or choose a Garden Analysis Report when conditions need inspecting.
Take the assessmentClient access is where property-specific notes, seasonal priorities, plant relationships and previous work can stay connected to the garden.
Client accessWhere a recommendation depends on soil, drainage, pests, plant health, safety or structural work, CGM will not present a generic article as a definitive diagnosis.
