Since I can’t get out and about. I thought I’d share my way of dealing with lobelia seeds. I often read the problems associated with lobelia, yet I find it one of the easiest to grow. Having said that, many of my methods were learnt through trial and error.
1. Surface sow the seed onto moist compost in 4 or 5 rows and mist to adhere to seed to the compost. Here I’ve used the half size seed trays but you can use any size you wish. Put into a carrier bag and using the handles, loosely tie so as not to let any moisture escape. Put into a warm light room/greenhouse and check at least once a day. Water using a fine spray bottle. Once germination has started remove from bag and position in a bright place, away from direct sunlight – direct sun will burn young seedlings.
2. The seedlings should look something like this after a few weeks.
3. When the seedlings reach this size they’re ready to be split and put into individual pots/modules.
4. Using a ruler for example, run it along the edge and underneath – very similar to loosening a cake from its tin.
5. Using the ruler, use it to cut each row.
6. It should look like this once it is separated.
7. I find the ruler comes in handy when lifting from the tray.
8. Gently split into little clumps – they are very robust, so do not worry.
9. And pot on, into cells.
10. Then finally water from below – here a poundshop cat litter tray does the bizz………and transfer to a warm greenhouse for them to grow on.
After a few weeks the roots should have took and the plant will have grown in size. This is the time to transfer the trays to a non heated place until its time for hardening off, which usually lasts for 2 weeks. Once the risk of frosts and nasty weather has passed they’ll be ready for planting in your favorite places. And don’t forget, for great displays feed regularly – just like us, they need food to maintain their looks throughout the season.
So, if you fancy giving Lobelia a go – this is a great method and one which works for me. Happy gardening. 🙂
