I put some daylily seeds in the fridge for two weeks, then I put them in a zip lock bag for about 4 weeks, in my widow, faces nw. Well anyway I have my seedlings in some 3" pots. I'm having trouble keeping them alive, because I don't know if I'm overwatering them or underwatering, and don't know when to plant them outside.

You should post your problem on the daylily forum.

Sorry I cannot offer any other advise.

A north-west window in the fall probably does not give enough light.
I would move them to a south window or else use fluorescent lighting if you can.

How large are your seedlings? If possible, you are going to want to get them planted fairly soon so they can get established before winter. Or were you planning on over-wintering them indoors? Don't know enough about day lilies to know if that's possible.

Are your seedlings large enough to put outdoors for some sunlight? You'll want to introduce them gradually...

seedlings are about 4-5 inches tall. They get enough light, I just don't know if how to water them. I know that sounds stupid, but I'm afraid I might be overwatering them.

My limited experienced with daylilies is that they are pretty hardy. I never water the ones I have in my yard, even in period of drought. However, mine are all pretty well established, so don't know too much about seedlings. Have you checked on the daylily forum?

At that size, I'd think they'd be ready to go outside soon. Are you planning on getting them in the ground before next spring? If so, I'd get them acclimated to the outdoors fairly soon--they will need time to get settled in the ground before our first frost/freeze.

Rosey, all this advice is good. Daylilies are indeed pretty hardy. I WS some daylily seeds two years ago and they've spent the succeeding time since in pots 'cause I was lazy and couldn't decide where to put them in the ground. Last winter I just sunk the pots in the ground to over-winter them and out of 10, I lost only two over the MA winter. I'll probably plant some in the ground this fall, and leave some in their pots (sunk in the ground again.)

I'm very experienced at watching seedlings die inside, especially from overwatering. Once thing that might help is using a sedling mix that does NOT hold a lot of water. In other words, one that drains freely.

Maybe you wnat to start seeds in something a little more "chunky" and less fibrous. The Container Gardening forum has some threaqds that explain at length why a container may dorwn your roots if it encourages water to "perch" in the lower few inches of the pot.

Too much water means no air, which means dead or inhibited roots. I think I have seen that a lot in my seedling trays.

They speak well of "pine bark fines", sized around 1/8th" ... like 1/10" up to maybe 3/8", but not many bigger than 1/4". Coco-Puff size. Mixed with just a little Perlite and peat moss.

I'm not sure if small containers also were supposed to include finely-shredded pine bark.

What baffled me was they suggested no more than 1 part in 6-7 peat moss. It sounded like really chunky mix.

Now I think the "around 1/8th" rule for pine bark chunks may have applied to coarser outdoor soils.
I shouldn't re-interpret what they were saying in the "Container Grdening" forum, I have no experience that way (excpet for killing lots of seedlings in shallow cells and fibrous, wet, peaty mixes.

My Soil

I'll give two recipes. I usually make big batches.

3 parts pine bark fines
1 part sphagnum peat (not reed or sedge peat)
1-2 parts perlite
garden lime
controlled release fertilizer
micro-nutrient powder (substitute: small amount of good, composted manure

Big batch:

3 cu ft pine bark fines (1 big bag)
5 gallons peat
5 gallons perlite
1 cup lime (you can add more to small portion if needed)
2 cups CRF
1/2 cup micro-nutrient powder or 1 gal composted manure

Small batch:

3 gallons pine bark
1/2 gallon peat
1/2 gallon perlite
handful lime (careful)
1/4 cup CRF
1 tsp micro-nutrient powder or a dash of manure ;o)

Thanks, everyone for your information on my daylilies, but they did not make it. I have enough seeds to try the way you all have suggested so I'll try again.
