Customer FAQ

Are Alsoils+ the most trusted supplier of compost and soil conditioner in the area?

Our experts have been servicing domestic and trade customers in Hampshire for over 35 years with the highest quality products, leaving you safe in the knowledge that we can cater for your needs.

Can I apply soil improver or manure during winter?

Yes. Winter is an excellent time to apply well-rotted manure or soil improver. These materials break down slowly in colder conditions, enriching the soil structure and nutrient content in time for spring planting. Apply during frost-free periods and dig in where possible for best results.

Is bark mulch still effective when applied in winter?

Absolutely. Bark mulch acts as a protective layer, helping to insulate soil, retain moisture, and reduce weed growth over the winter. It’s particularly useful for shielding roots from frost and preventing surface compaction caused by heavy rain.

Will winter products benefit vegetable patches and allotments?

Yes. Digging in manure or soil improver during the dormant season helps replenish nutrients and improve soil condition ahead of spring sowing. Bark mulch can also be used to protect overwintering crops or suppress weeds in unused areas of the plot.

Can I use these products in wet or frosty conditions

While these products are designed for winter use, it’s best to avoid spreading them when the ground is frozen or waterlogged. Aim for a dry, frost-free window to ensure even application and effective incorporation into the soil.

How much coverage do I get from a bulk bag?

One 750-litre bulk bag typically covers around 10–12m² at a depth of 5–7.5cm. Coverage can vary depending on the product and how it’s applied—for example, mulch spread as a surface layer will go further than manure dug into soil.

I ordered a delivery of mulch for my front garden from Alsoils and on delivery the driver had a tricky manouvre and caught caught the edge of our newly laid metal edging on the drive. Accidents happen. The measure of a company is how they react. The driver was apologetic, took responsibility, and briefed the office. When I called them I was passed to Matt (Director) and he took was apologetic and they offered to pay for the damage caused. No quibble at all. We're so happy with the product, and the aftercare we received from this company, that I have just ordered another delivery of their mulch for the back garden. Top product and great customer service. Highly recommended

Excellent selection of products on the website, ordering process was simple, communication great throughout and delivery was fast. The driver was helpful and courteous ensuring the 2 bulk bags were delivered to where I wanted them. The product (lawn topsoil) was of impressive quality and easy to rake out over the existing lawn and now the seed is taking well thanks to the quality. Will use again as well as recommend to others.
