We're passionate about our gardening here at Harrod Horticultural and we encounter the same pests, diseases and general gardening problems that afflict kitchen gardens, vegetable patches, allotments and borders - not to mention raised beds, pots and containers - across the country.

We're also lucky enough to have two very knowledgable horticulturists on board to help out with advice and hopefully provide answers to those frustrating problems you can't solve yourself. Both Martin and Julian have qualifications in horticulture and it's this initial grounding, combined with their experiences 'in the field' - literally - which helps them provide the in-depth answers you can see below.   
 
They'd both love to hear from you - just click on their respective pictures below to send them an e-mail - but before you do, we'd thoroughly recommend you browse through the ever-growing list of advice they've already imparted below. You might find the answer to a problem just like yours! Click here to contact Martin, our resident Horticulturist and Master Composter, with your gardening queries
