mould

[crannman]

hi all got some white fluffy mould on seedtray the trays are planted with flower seeds the greenhouse ih heated no seeds have come up yet any ideas

[bearded bloke]

Are they in compost ? if so check the back of the bag as some MPC contain ingredients that can produce a harmless mould.Similar to ........

[crannman]

yes they are in compost and read instructions on compost bag and no mention of mould some trays have it others dont all in samd compost

[rustylady]

The compost is probably a bit overwet, and not enough ventilation.

What seeds are you trying to germinate?

There's a white mould appearing in my propogator, I planted stuff in it over two weeks ago and lettuce is the only thing that came up yet. The spring onions, red onions and leeks haven't done anything.

[bearded bloke]

Darwin,I'm not sure but I think the alliums take longer to germinate than lettuce,check your seed packets it normally says on the back

[bearded bloke]

Not a very good picture I'm afraid,but I found this mouldy twig in a bag of MPC this afternoon while potting up ....................

What temperature is the propagator set at? Onions germinate best at 18ºC/65ºF. At that temperature they should germinate in approximately 10 days. At lower temperatures it will take longer and you may find the germination rate is much lower as well.

Good point AP ^^,I never gave temperature a thought as mine is fixed

[Darwin.]

It's not a snazzy one, just a tray with a plastic cover I got in the garden centre so I can't set a temperature. It's as warm as the conservatory and at this time of year that can be very cold.

[Aberdeenplotter]

Just so I have got this right, this is just a tray with a plastic cover? It is not a heated propagator?

[Darwin.]

Not heated.

It says propagator on the box though

[Aberdeenplotter]

Ok, here's the deal. Pop your propagator into the airing cupboard, but check every day and take it out as soon as you see signs of growth and then put it into full light. Cold wet compost and mould kind of go together.

It was grand last year but I planted things out about a month or 6 weeks earlier this year. I'll give that a go, cheers.

I have a second smaller one that I planted peas in and they're doing well.

I though most folks had non electric ones, the electric ones cost a fortune don't they?

[Aberdeenplotter]

one second hand on fleabay at the moment. heated seed tray | eBay. cover is cracked but they are really cheap. Have a go if it's of interest.
