Overview

Beds and Borders Topsoil is a sandy loam, screened to 20mm and blended with organic compost, so the fertility is already in the bag rather than something you buy and dig in separately. It is friable and low in stones, so it spreads and levels easily, and the organic fraction holds moisture while the sand keeps it draining. You can plant into it the day it arrives. It suits flower beds, shrub and perennial borders, raised beds and large containers. In a planted bed it is worth the extra over a plain screened topsoil for a number of reasons.

Why Professionals & Homeowners Choose Beds and Borders Topsoil

Six reasons this grade earns its price in a planted border:

  • The compost is blended right through it, so a new border does not need a separate bag of conditioner in its first season.
  • A sandy loam drains freely while the organic fraction holds water, which is the awkward combination border planting actually wants.
  • Low stone content and a friable crumb, meaning it breaks up in the hand rather than coming out in clods.
  • Screening at 20mm is coarser than our 10mm grades, so it is right for planting, wrong for direct-sowing fine seed, and you should expect the odd stone.
  • The nutrients come out slowly as the organic fraction breaks down over roughly two years, rather than a fertiliser that washes through in the first wet fortnight.
  • One 850kg bag fills a decent border in a single delivery, instead of forty small bags off a garden centre pallet.

Beds and Borders Topsoil Applications

A fertile, free-draining loam is the standard border soil and it grows the standard border plants well. Japanese anemone (Anemone x hybrida), masterwort (Astrantia major), lady's mantle (Alchemilla mollis) and shrub roses all take to it, and so does general mixed planting once you have given the bed some depth. The exception is the acid-loving family. Camellia, pieris, rhododendron and blueberry (Vaccinium corymbosum) want a pH of roughly 5 to 5.5, which this soil is not, and they belong in Ericaceous Topsoil. It is also too rich for a wildflower meadow, where poor ground is the whole point, and too coarse to sow fine seed into.

  • New borders and flower beds, mixed into the top 150 to 200mm of ground you have loosened first.
  • Restoring an old border that has dropped, at 75 to 150mm over what is already there.
  • Filling raised beds, where 250 to 300mm gives ornamentals and most vegetables the depth they want.
  • Patio pots and large planters, where the compost fraction stops it drying out.
  • Shrub and perennial planting, mixed with what you dug out, so the roots spread into the surrounding soil instead of staying in the hole.

Beds and Borders Topsoil Maintenance

Beds and Borders Topsoil arrives with enough fertility for its first growing season, so the job in year one is just watering rather than feeding. A sandy loam drains fast, so a new border on it wants checking every few days in a dry spell, well before the clay bed next to it needs anything. From the second year an annual mulch keeps it working well: 5 to 7.5cm of composted bark or well-rotted organic matter over damp ground you have weeded first, in autumn or mid-spring, then left alone for the worms. Expect the surface to settle after the first heavy watering, which is what the extra ten per cent in your order is for. Imported soil always brings some weed seed with it, so hoe the seedlings off through the first season rather than digging them back in.

Purchasing Tips

Work the order out before you buy; length times width times depth in metres gives you cubic metres. An 850kg bag holds roughly 0.6 to 0.7 cubic metres, so it covers about 4 to 4.5m2 at 150mm and fills a 1.8m by 0.9m raised bed to 300mm with a bit left over. Add ten per cent to any project to account for settlement. The bag weighs 850kg and gets dropped at the kerb, so work out how you are moving it before it. You cannot judge a soil from a photograph, so read the description for the texture and the screen size.

Beds and Borders Topsoil FAQs

What is Beds and Borders Topsoil made of?

Beds and Borders Topsoil is a blend of natural sand, silt and clay screened to 20mm and mixed with organic compost. The compost fraction is what carries the fertility and most of the water holding.

How deep should Beds and Borders Topsoil be laid in a border?

Beds and Borders Topsoil wants 150 to 200mm in a new bed and 75 to 150mm when you are topping up an existing border. Allow 250 to 300mm in a raised bed. Break up the ground beneath it first, or the roots will stop where the new soil stops.

Can you grow vegetables in Beds and Borders Topsoil?

Beds and Borders Topsoil will grow vegetables, and it is sold for productive borders and raised beds as well as flowers. Where a bed is mainly for food, our Vegetable Topsoil is the grade stated and tested for home growing, and it is screened finer at 10mm.

What is the difference between Beds and Borders Topsoil and Landscaping Topsoil?

Beds and Borders Topsoil carries the heavier compost fraction and is aimed at planted beds, borders and containers. Landscaping Topsoil is the general purpose grade for turfing, tree planting and whole-plot renovation.
