Erigeron - still so tiny

Kmeh · May 2020

Evening

I have grown some erigeron glaucus from seeds. This is my 2nd attempt and I got 1/3 of those sown to germinate - not great conversion but I will take it.

They were planted at the beginning of april and are still a measly 1-3 cm. They've been inside in a lovely warm spot. I transplanted them into larger pots today but they seemed to have very little root system to them.

Anyone out there have any tips on erigeron?

Many thanks

What kind of soil mix are you using? Lots of people recommend a very gritty, poor mix (as they grow in gravel, paving etc). But I put some into a high manure mix and they romped away happliy. Maybe try a slightly richer soil.

I understand they have a difficult germination rate, much easier to propagate by division (nick a bit from a friend).

You've probably moved them on too soon as well. If they weren't filling the pot with their root system, there's no point potting into bigger pots. Better to wait

@fire I started them off in 2/3 seedling compost mix, 1/3 perlite. It's been fine for most things but admittedly erigeron do seem to be a different beast of a seed.

@fairygirl - I was wondering whether they may have used up of the nutrients, plus I had 3 in a 5 x 5 cm pod - so thought maybe they needed more room. The lack of large roots clearly shows not the case, right?

The new pots are 1/5 grit but perhaps in should have done more? At 1-3 cm are they too small to put outside?

If they had no real root system, it's always better to wait a while until they do.
I wouldn't put anything that size outside. Other people may have a different view though - it's not a plant I've ever grown from seed.
It's completely different if something seeds in situ of course.
