When to Plant

The best time is in the autumn, ideally in September or October before the ground becomes too wet and cold. Plug plants can be transplanted in May and June; however, they will often require more watering and nearby weed control if planted at this time of the year.

Planting Tips

  • Ideally use plug plants that are six months to a year old.
  • Make sure the roots of the plug plant can be seen at the bottom of the pot before planting out. 
  • Before planting, strim/cut the area and remove the cuttings. Another option is to dig out a small patch of turf with a spade, turn it upside down and return it to the hole. This exposes the soil and kills the grass.
  • Dig a hole the same size and depth as the plug.
  • Invert the pot and gently tap and squeeze it to remove the plant and insert it into the dugout hole.
  • Put the soil back around the plant and firm well with your hands or a foot.
  • Water in the plug plant.
  • Mark the location of the plant plug with a garden cane or similar. This will allow you to easily find the plant again for watering and checking progress.
  • For more than one plug: plant in clumps of 2-5 plants per sq m.
  • Seed is also best sown in the autumn as the ground is damp and they will have little competition from other plants/weeds.

Plug Plant Aftercare

  • If planting in May and June regular watering will be needed for six weeks after planting, particularly if the weather is dry, as drought is the commonest cause of plug plant failure. 
  • Keep the grass short around the plants for the first year after planting out.  This reduces competition and helps the plant plugs establish better.
  • If you start to see slug damage, you may need to use slug control – try to use animal friendly methods.
  • Avoid grazing the meadow for about six weeks after planting out plug plants, and a bit longer if on thin soils and/ or slopes.
  • Once the plug plants are established, manage your meadow as a hay meadow or pasture. 

Managing Your Garden/Meadow

Your garden/meadow won’t need a lot of care and attention once it’s established. A bit of regular maintenance should be all that’s required. This includes:

  • Regularly removing thistles, docks, tree seedlings and any grasses that look like they are taking over the patch
  • You may want to ‘top-up’ your meadow in its first years of life, sowing more seeds to fill any bare patches
  • From September until the grass stops growing:
    • Mow the meadow regularly to a height of 2-4cm, otherwise the seedlings will be shaded out.
  • In early spring:
    • Start mowing but stop in mid April to allow the wildflowers to grow (bearing in mind that many species take a couple of years before they flower).
  • Late Aug to mid-September:
    • Mow the meadow once to a height of 5cm. Leave the cuttings for a day or two to allow any wildflower seeds to be shed and then rake the cuttings off and compost them. By mowing later in the season you’ll be giving late-flowering plants the chance to set seed – and providing pollinators with an extended supply of nectar and pollen rich plants.
    • As an alternative to cutting in late summer you can leave the patch over winter before cutting in early spring. Your meadow’s dead stems will provide excellent insect hibernation spaces over winter
  • In the second and subsequent years, mow whenever the vegetation grows to 10-15cm tall but don’t cut it shorter than 5cm and stop mowing between mid-April and mid-July (or September). Always rake the cuttings off, but after the summer cut leave the clippings for a day or two before raking them off. Never add fertiliser, as this will help the grasses to out-compete the wildflowers.
  • After a few years, once the wildflowers are fairly established, following the summer-cut you could try leaving part of the meadow uncut until early spring, so that birds can feed on the seed heads and insects can hibernate in the long grass.
