I`m having problems with mold on my compost with non emergence of seedling and damping off, even after careful cleaning of all my trays. I was wondering if the blue copper sulphate sold on ebay is the same as the one that used to be available for the problem? I have quite a few expensive petunia seeds to sow and I don`t want to loose any more.

I just found an old thread from last year when I had the same problem. I meant to microwave the compost this year but for got all about it.  |

I found that microwaving made no difference. I have a high rate of non germination this year again too. Don't have any mold and have followed all instructions too. So disheartening.

I used to dust my sweetpea seeds with Murphys Copper Fungicide but I don't think you can get it now. There is liquid copper fungicide I think but haven't checked it out as I've only just saw this
You can also check out Bordeaux Mixture.

Could somebody explain to me what "damping off" is ?

Could somebody explain to me what "damping off" is ? Its a fungal disease which causes newly emergent seedlings to wilt and die off. usually caused by overwet compost or unsterilised compost etc. You can't cure it but easy to prevent.

Hmm.. I wonder if I am suffering from this ? I've planted 70+ pots with onion seeds in ,and not a single one has germinated !

What sort of compost were you using roofgardener ? Was it reasonably fresh or had it been stored since last year? Try sowing your seeds on top of the compost and covering with vermiculite also onion seeds are large enough that you can space them out a bit. ps the correct terminology is to SOW seeds and PLANT bulbs and plants. Yes I know I'm an old pedant  |

Yes I know I'm an old pedant ROFL.. I shall bear that in mind sweetpea  Hmm.. the compost was new. Well, new in January anyway. I sowed them one or two to each seedling plantpot (small 1" pots). However, the seeds WHERE at least three years old... possibly 4 years... so perhaps I should start again with new seeds ? I think I've got some vermiculite... I'll give your suggestion a whirl. Thanks for that

Thanks for that Seeds vary in their viability as some you can keep for years and others really need to be sown fresh. Also how they are kept can greatly influence their viability. When you see seed packets displayed out in the blazing sun for instance, give them a miss. Sweetpea seeds may be stored in a domestic freezer and still give good germination rates up to 7 years as long as they were fresh to begin with on the other hand Parsnip seeds will have a poor germination rate after the first year. Other factors come in to play as well eg depth of sowing and exposure to light so it pays to which seeds require what. this might help: link

The seed viability chart in your link suggests that Onion seeds are only viable for a year, which explains my problems perfectly ! Thanks for that sweetpea

I hold on to my seeds for years Roofy , sometimes they germinate and some times they don't. I've even had failures one year and success the next with seeds from the very same packet  I bought several packets of the same stock seeds from ebay in 2009 ( the year is on the front as they were free with garden news ) so far every year , except last year for some reason they have germinated from both sealed packets ore opened packets. I sowed seed from the last packet and guess what they have germinated well . Thats 11 YEAR OLD SEED Do you need any onion or veg seed ? I have several packets of onions, all in date that I`m not using if you`d like them. Bedford champion and red one ( for salad or bulb ) plus spring onions. Just PM me your address. |

Not all my seeds are damping off . I have to admit the fresh seeds seem to be thriving even the lobelias. Anyway this morning someone very kindly sent me the solution in the post ( you know who your are) The banned substance  Sowing tomorrow again and I will post an update . |
