How much does mulching a garden cost?

Our borders are looking tired and I've been told mulching them would help. What do gardeners typically charge for this? is it priced by the bag or by the area?

"Applying a mulch such as compost, pulverised pine needles or leaf mould is certainly beneficial to any soil. Price depends how many sqm the borders are. I personally wouldn't use bark as the natural bacteria it attracts tends to rob nutrients from the soil. I certainly wouldn't recommend applying a weed fabric on cultivated borders either as that's not what it is intended for. It's intended to go under gravel areas, driveways, and to protect drainage pipes. I'd be aiming for a layer if roughly 3 inches applied directly onto the soil across the whole border to make any noticeable difference in weed suppression, moisture retention and soil conditioning."

"a bulk bag would be 500 litres and at typical depth of 2-3 inches this would cover 8 sq.m approx and cost £85 from your nearest builders merchant. But its light and easy to spread typically with some prep and laying a weed membrane - a couple of hours work @ £30/hour would cover a sizeable area. I would charge for the job if given exact size of area."

"Mulching is normally priced according to the size of the area rather than simply by the bag. I would first measure the borders to calculate how much mulch is required, then add the cost of materials, delivery and labour.

As a rough guide, a small garden mulching job may be around £110–£200 including materials and labour, with larger areas costing more. I would normally inspect or ask for photos and measurements before giving an accurate fixed quote."

"Garden mulching is usually priced based on the size of the area, plus the cost of the mulch needed. The price can vary depending on the type of mulch, how much preparation the borders need and how accessible the garden is.
For a small area, it may be charged as a minimum job, while larger borders are normally priced by the square metre. I’d recommend getting the area measured and then getting a quote that includes the mulch and labour."

"we charge by the area, as it will include materials & labour to do the job.
or sometimes the customer will supply materials and then just be charged labour to do the job.
hope this helps. thankyou!

"You would be looking at approximately £20 per square meter supplied and laid."
