How to grow mondo grass between pavers

A green groundcover growing between pavers lends an impeccably manicured look. With this technique, you can lay on lawn, sand or soil, and there’s no need for major excavation. If laying on an established lawn, simply remove the top layer of turf with a shovel, then level and pack down the soil beneath.

Tools and materials

Safety gear

Mini roller and tray


Rubber mallet


Gardening trowel

Watering can

Spirit level

Tile cleaner

Concrete pavers 400mm x 400mm x 40mm

Clear matt paver sealer

Spacers 184mm x 400mm (x 2) – we cut ours from pine offcuts

Metal spikes or pegs

Builder’s string

Quick set concrete (one 20kg bag for six pavers)

Road base (half a 20L bag for six pavers)

Top soil or compost (one 25L bag for six pavers)

Mondo grass (one large tray surrounds six pavers)

Before you start

Ensure the surface is flat, even and solid before setting out the pavers, which are raised off the ground to allow for the planting

1. Clean and seal the pavers

Use tile cleaner on the top of the pavers, washing away the residue. Apply a natural-look sealer using a mini roller, working quickly to apply two coats, then leave to dry for a couple of hours.

Tip: Sealing pavers before laying keeps them looking cleaner for longer.

2. Position the pavers

Rake the space to create a flat, even surface. Then position the pavers, spacing them using the 184mm-wide timber offcuts. At the corners of the setup, use a mallet to tap metal pegs into the ground, leaving them to protrude by 50mm, then run string around the pegs.

3. Mix and lay the base

Wearing a mask, fill a bucket to just over half with quick set concrete then fill the rest with road base, combining with a trowel. Reposition a spacer next to the first paver, remove paver, then trowel concrete mix over the square to create a level base 20mm high.

4. Lay the first paver

Use a watering can to saturate the concrete mix then work quickly to position the first paver, agitating it slightly onto the base to sit evenly. Check that it’s flat using a spirit level, tapping into position with a rubber mallet and checking for square against the string.

5. Check and lay the rest of the pavers

Set the pavers, one at a time, positioning spacers either side as the formwork for trowelling on the concrete mix. Use a spirit level to check each paver is level with the adjacent pavers, tapping into position. Leave the concrete to cure for at least two hours.

6. Plant the mondo grass

Wearing gardening gloves, use a trowel to create a 20mm-deep layer of top soil or compost between the pavers. Make holes for the mondo grass and plant them out evenly, adding more soil as needed. Water well and keep moist till established.
