Ordering Information
How To Grow – Plant from autumn through to late spring in a sunny but sheltered spot with well manured free draining soil. Strawberry runners should be planted every 45cm (18”) in rows spaced at 75cm (30”) apart. At the time of despatch, plants will be semi dormant and may have very little foliage; this is completely normal. Please plant as soon as possible upon arrival, this will revitalise the plants and new growth will start to appear. When planting, spread out the roots and place them in the soil at a level where the crown of the plant is just above the surface. Alternatively, they can be grown in growbags (10 plants per bag), or in hanging baskets or containers.

More Information – Fresh dug strawberry plants are available from late October to December. Coldstored strawberry plants are available from January to late June. The prices listed are for quantities per thousand, if you wish to place a smaller order please get in contact with a member of the team.
