Tree & Shrub Planting Composts
- When planting trees and shrubs, particularly high value container grown and bare root stock, it is recommended that a suitable tree and shrub planting compost is incorporated into the planting pit.
- Excavate a hole of suitable size, as set out in the Contract Bill of Quantities.

- Depending on soil type, manufacturers instructions and details as set in the Contract Bill of Quantities, thoroughly mix the appropriate amounts of compost into the excavated soil.
- Carefully plant the tree or shrub into the hole and back-fill the mixed soil and compost. Firm down well.
How to Accurately Check the Correct Incorporation of Tree and Shrub Planting Compost
- Precise details of the product name, specification, quantity required for each planting pit and pit size, should be clearly stated in the Bill of Quantities.
- Physically measure the pit size - depth and diameter/section, after excavation and before planting.
- Physically check the incorporation ratio of soil to compost. Remember to check the compost size bag - ie. 75, 80 or 100 litre.
- If any doubt, obtain proof of quantity and size of bags ordered and delivered.
- Checks can be made after planting, by removing the tree or shrub and carefully excavating the back-fill onto a polythene sheet. If it was not possible to confirm the incorporated amount, send a number of samples for independent analysis.
- Any shortfall should be rectified at the contractors expense.
