Mould problem

I've sown some Delphiniums in a pot covered with Vermiculite (sp) about a week ago & on checking yesterday a very fine mould has appeared, its covering the surface & today its got thicker, its plain white, any ideas what it could be? I've used the same compost/vermiculite (fresh) on all the other seeds I've sown & nothing has appear on them :confused:

hi Helen,dont know for sure but maybe if its just the single pot and all others are ok.could be that that certain pot had some kind of bacteria in it.are the pots new?

 

Yes the pots are new & I always disinfect even new pots with Armillatox, its very odd, the only thing I can think of is that the seeds were "off"

Mildews;these fungal diseases attack stressed plants,those that have become dry at the roots,stagnant air conditions.Avoid overcrowding and keep consistantly watered,devours affected leaves and shoots from the outside.Downy mildew is more serous,can penatrate the leaves and eventually kill the plant.
Grey Mould(botritis)another fungal disease,which thrives in cool damp conditions,covers leaves and stems.improve airflow,drier conditions,remove affected parts.Hope this heps.

 

I would also move them away from other pots

 

Watering in with Cheshunt Compound will help,its an old fungus preventative but works well.

 

I to used Chestnut Compound last year when my seedling were suffering from dampening off it worked well I was pleased with the results
