When it comes to the actual nitty gritty of getting the seeds in – the depth at which they are seeded and whether they are covered or not can make it or break it for success with germination. Here are a few notes from our experience:
THING #1 before you even start this procedure:
– Make SURE your seeding trays have water drainage holes!! –
- The rule of thumb for seeding is: sow the seed twice the depth as the seed width.
- Sow seeds in rows so the seedlings are organized once they germinate.
- Avoid seeding thickly, sow moderately so the seedlings have adequate space to grow
- Rule of thumb for covering is: any seed the size of a Salvia or a Pansy seed and larger should be lightly covered with vermiculite (our choice) or the same fine seeding soil to keep them moist. We actually keep a salvia seed taped on our seeder as a visual guideline for covering seed.
- A Salvia seed and a Pansy seed are pictured in the accompanying photo – Pansies are the smaller seed & require less covering, so cover lightly; and as seeds get larger, they need more covering material.
- Keep everything moderately moist – too wet or too dry both affect germination. If they are too wet, they will rot – that’s why it is so important that your seed tray has drainage holes and if they are too dry, they dry out and cannot germinate.
