Everything you need to know

How it arrives

Our Soil Improver (also known as soil conditioner) is available in small bags, large bulk bags, or full-pallet sizing. All orders are shipped on a pallet via our trusted courier network, with delivery to the kerbside or the nearest safe, accessible drop-off point. 

When you select the bulk-bag option, the pallet is offloaded using a tail-lift and moved with a pallet truck. Because of this, delivery requires a firm, level surface. If access to your property is difficult or uncertain, please contact us on 01243 781730 before placing your order so we can advise on the best delivery option. 

Once dispatched, we’ll send you tracking information. For large orders, deliveries may be split across multiple pallets depending on weight and amount.

Our soils and composts are independently certified and tested, so you know exactly what you're putting in your garden.

FAQs

This depends on your goal! If you want to improve the growth of your plants, enjoy more blossoms on your flowers, and provide your garden with additional nutrition, then you should use compost.

However, if you want to reduce weed development, manage run-off and keep soil moist, then it’s mulch that you need.

We recommend using enough compost to blend with the existing soil in your garden at approximately a 20-30% ratio. This will ensure there is enough compost for your plants to get all of the nutrients they need, whilst not being the only soil in the mix!

Remember, Earth Cycle organic composts are soil additions and have been created to mix with the topsoil already in your garden. For more information on how much compost you’ll need for a particular project, get in touch with our team on 01243 781730 – we’re happy to help! Alternatively, if you’re buying bulk compost for delivery, then why not use the help of our Bulk Bag Calculator for a quick and easy calculation.

We recommend that somebody is present when the delivery arrives, but we can still deliver if you are not in.

Our drivers are highly skilled and will determine the best accessible place to leave your order. Should you not be present when your order arrives, but you have particular instructions of where to leave your delivery then please let us know.

Please note that we cannot accept any liability for the theft of unattended deliveries.
