Sow Indoors

Can be sown indoors March-April

Sow seeds thinly on the surface of moist fluffy compost (do not cover with more than 5mm of soil as they need light to germinate)
Place on a warm windowsill and cover with a propogator lid or polythene bag until germination occurs. Germination can be erratic transpiring between 10-90 days…be patient :0)
Plant out in clumps once all risk of frost has passed. * Be sure to harden off indoor raised seedlings first

What Does Hardening Off Mean?
Plants raised indoors or in a greenhouse environment, need to be acclimatised to cooler temperatures and increased air movement for about two to three weeks before they are planted outdoors permanently. This is a ‘toughening up’ practice to prepare the plants for their new environment.

How to Harden Off
Place your plants out for a couple of hours in a shady part of the garden. The next day, leave them out again for two hours, but this time allow the plants an hour of direct sunshine in the morning. Gradually continue to increase the length of time the plants are in direct sunshine over the course of roughly two weeks.

Sow direct

Can Be sown Directly outdoors April-May

Sow seeds onto a prepared soil in a sunny spot which has been raked to a fine tilth
Rake the seeds gently into the soil, but do not cover with more than 5mm of soil, we need the light for a succesful germination

Sun and Water requirements

Cloud Grass likes a full sun or partial shade position. Water regularly, more so during periods of drought.

Will Cloud Grass Self Seed?

Oh Yes! Cloud grass will self seed freely, throwing up new shoots the following spring! To avoid this, simply remove the seedheads or simply pull out the new shoots the following spring- *unlike other grasses cloud grass has a very shallow root system and is therefore quite easy to manage.
