Eco Tree & Shrub Organic Compost questions
Q. How does phosphoric acid in compost helps trees grow better?
Some trees and shrubs prefer a more acidic soil. Our Tree & Shrub is made to order and we create this by adding in acid. This will lower the soil’s pH value to encourage young trees and shrubs to establish.
Q. How long does it take to make organic compost?
Local garden offcuts are processed and matured for up to 12 weeks. The oxygen levels and temperate have to be optimal to create the perfect environment for the material to breakdown. Our dedicated team go through stringent quality protocols and conduct daily checks as per PAS100 protocol.
Q. How much compost will I need for garden project?
To work out the volume of the area you are working with, you will need to use the formula length(m) x width(m) x depth(m). The answer will give you the cubic meterage of your chosen area. We’d recommend a depth of 5cm. Alternatively, use our free volume calculator.
