Crust and germination

Post  milaneyjane on 5/17/2011, 9:32 pm

I have the dreaded "crust" that some have commented having in their MM. I think mine is due to a certain box stores idea of compost that I ammended my boxes with this year. Evil or Very Mad It looked great in the bag all moist but dried out really crusty. Underneath the crust it looks great. So the problem now comes in with seed germination of my carrots-which is about 9 squares worth and a few other seeds. Not so good. I would have expected my seeds to start to germinate by now a little better than they are. I think it is because the seeds are continually drying out in the top crust. Starting yesterday I have been using a misting hose and thoroughly wetting the soil every morning and night since it has been breezy. I debated covering with plastic but I am afraid I would fry the seeds now that it is warm out. Any suggestions?

Stick with it. They'll show. If Mother Nature can't destroy seeds with this spring's weather, you certainly can't. I bet they poke up in a few days. Just keep keeping them moist.

Happy Gardening!

How long have you had your seeds in? Some of them take a while. Since you're having trouble with crusting, what you're doing with the misting is very good. They'll continue to need that until the roots get down under there.

Finding a good compost that you know for sure has no peat moss in it, and mixing it into each square as you can (or the whole bed once you've pulled everything out of it), will help break up the crust. The crust is likely caused by peat moss that was added to the peat moss you bought.

Depending how much peat moss was in that compost, you may have a nutrient deficiency. Until you are able to add more compost throughout, you may need to side-dress with worm castings or fish emulsion, or supplement with compost tea or possibly fertilizer.

Just watch the growth of your plants. You'll probably know if they need it. Smile

Your germination times sound pretty normal to me, especially since it's not that warm right now in Michigan. Even down here, my first round of carrots took a while. Not quite that long, but we had a warm end to winter. flower

I was talking to a neighbor about the crust the other day. He explained that beans will sometimes "break their necks" when they try to pop out. He suggested planting radishes in-between or along side. They will sprout earlier, and make cracks in the crust so the carrots (beans) can pop out normally.
