Ive got a heated propagator.I am a little unsure of what stage after the seeds have germinated do I open the vents,or do I remove the lids,and how long do I leave the seedlings on heat for?Any advise please!

You should take them out of the heated propagator as soon as most of the seedlings have emerged from the compost or they will get leggy. I usually put another propagator lid over them for a few more days just as a bit of added protection.


Thankyou for your advise,my dwarf Dahlia seedlings are alive and now out of propagator!
