The channel launched in partnership with teleshopping company JML in March and is extending its weekly broadcasting hours from five to 70.
From 8 April, Home & Garden Plus will be available from 0800-1800 daily on Sky Channel 642/Freesat 809.
Popular selling lines so far include fruit, and potatoes. The channel will expand its range to TV viewers to include bedding plants, bulbs, grow your own fruit and vegetables and garden hardware.
Managing director and lead presenter Andy Hodgson and horticulture expert Peter McDermott both appear as presenters on the daily Home Garden Plus TV hours.
Hodgson said: "It’s great news that customers love our unique brand of gardening banter from our shed."
"Clearly, our free tips and low price offers are catching the imagination of everyone with a garden, patio or yard. Now it's recommended we eat seven portions of fruit and veg a day, we decided to open seven days a week."
