How to Grow Moss in Cracks Between Patio Stones


Growing moss in the cracks between patio stones is a great way to add natural beauty and greenery to your outdoor living space. Moss grows easily in the shady, damp conditions found between patio stones and helps prevent weeds from sprouting up. With a little effort, you can have a lush carpet of moss that transforms your patio into an inviting garden retreat.

Choosing the Right Location

The first step is choosing the right spot on your patio for growing moss. Here are some tips:

  • Moss thrives in shady areas that get minimal direct sunlight. North or east-facing walls work well.

  • The area should have good air circulation to prevent mold or mildew buildup.

  • Damp conditions are a must! Moss needs a constant source of moisture to survive. Areas that collect rainwater runoff are ideal.

  • Avoid high-traffic zones where moss may get trampled underfoot.

Pick an area with deep cracks between the stones where moss can take root. Flat stones with tight mortar won’t work as well.

Preparing the Space

Proper preparation helps ensure your moss will establish itself:

  • Remove any existing weeds, dirt, or debris from between the stones using a hoe, brush, or pressure washer.

  • Widen and deepen the cracks with a chisel to give the moss more space to grow. Aim for at least 1-2 inches deep.

  • Fill the cracks halfway with a 50/50 mixture of sand and compost. This gives the moss an optimal growing medium.

  • Level and firm the mixture gently with a trowel. Don’t compact it too tightly.

  • Water thoroughly until you see water pooling in the cracks. This moistens the soil prior to planting.

Planting the Moss

Now comes the fun part – planting the moss!

  • Purchase mood moss from your local nursery or garden center. Opt for varieties suited to shade like thyme moss or angel hair moss.

  • Gently remove clumps of moss from the container, keeping roots intact. Break apart any matted sections.

  • Press moss firmly into the cracks you prepared. Spread it out to cover all the gaps between stones.

  • Water moss deeply after planting. Mist frequently to keep it consistently damp.

  • Add more sand/compost mixture if you need to raise the level of cracks after planting.

Caring for Your Moss

With the right care, your new moss garden will thrive:

  • Water moss every 1-2 days with a gentle spray bottle. More frequent in hot, dry weather.

  • Mist moss daily to boost humidity.

  • Remove fallen leaves and debris promptly.

  • Apply liquid fertilizer monthly during growing season. Moss thrives on phosphorus.

  • Pluck out any sprouting weeds when they first appear.

  • Trim back patches of overgrown moss with shears or scissors.

  • In winter, reduce watering frequency and stop fertilizing.

Troubleshooting Issues

If your moss starts turning brown or patchy, try these troubleshooting tips:

  • Improve air circulation with a small fan if the area is too shady/humid.

  • Water more frequently if the moss is drying out. Or reduce watering if soggy.

  • Apply fungicide if mold appears. Remove affected patches.

  • Scratch up compacted moss with a brush to encourage new growth.

  • Transplant new moss into bare spots.

With proper location selection, planting, care and maintenance, you’ll be enjoying a lush emerald moss patio in no time! Be patient, moss grows slowly but the effect is well worth it.
