What Type Of Soil Is Needed To Fill A Raised Bed.
Raised beds for general planting are best filled with half loam soil and then topped off with John Innes number 3 mixed with half spent mushroom compost and a bucketful of well rotted manure per square metre
This will make a good airy mix, quite dark in colour which will absorb the sun’s rays and heat up quickly as well as holding moisture whilst being well drained. Its a good idea to make sure the soil/compost has a few earthworms as they will help to aerate the soil.
If using straight loam (top soil) make sure it is from a reliable source as it may contain perennial weed etc which might cause problems later.
For raised beds that are being created for plants that require acidic soil they will require a large amount of well rotted manure or well rotted leaf mould to help create a acid soil conditions these plants require.
