Thanks for the help. Im growing a little of everything to start my garden outside in may. I have about 7 trays. And no power outside unles we use a extenion cord. And again using 7 trays i think i would need to plug in would need to plug in 7 cords. Thx


The seed starting mix that I had doesn't say anything about fertilizer. it just says 100% organic.
And I am still currently waiting on some 4 o'clocks, zinnia, and Dahlia. I have had some zinnia and 4 o'clocks sprout already, but I have yet to see any dahlia seedlings...


You can try transplanting it into fresh potting mix and plant it with the affected part of the stem below the soil level in the new mix. Sometimes it works, sometimes not. Then reduce the watering. The peroxide spray 1:10 can't hurt, might help.

Another reason to hold back would be if your last average frost date is still in the future. Just because the weather's warm now, does not mean the warmth is here to stay. We had temps in the 80's at the beginning of the week. Yesterday the high was 45 and the hilltowns had night temps in the twenties. Planting out early would have been disaster, unless the gardener had a way to protect the plants from a hard freeze. You're in a warmer zone, so you may be good to go.
Those guidelines for what to start when are intended to help the gardener have a healthy plant of an appropriate size at the safe plant-out date, usually the last average frost date.

A common mis-perception. ;) Not only can the use of bottom heat post-germination cause leggyness but it also retards root development. In fact it can even "cook" (kill) young roots. So you would be sacrificing root development - which is the most important form of growth at this stage - for top growth.
With seedlings, slow top growth is what you are after. That's why professional growers in greenhouses work very hard to maintain air temps of 65 degrees max.

I have no answer as we're in different climates, but am interested in any others answers. Is it appropriate for me to ask similar question here, or start new thread? Im in low desert and already in high 80's. Got yellow bells from seed in plastic cups now 2 inches tall. Is it time to plant in the ground? thanks.

First; Your broccoli is just fine. New Broccoli leaves are green, Mature leaves do have a grayish cast due to a fine fuzzy coating on the leaves. Wet the top of the leaf a bit and you will see the green.
I'm assuming the fertilizer is water soluable. If that's the case then yes you can fertilize everything sparingly, including the peppers, but use the fertilizer at half or even 1/4 strength and do it after you water. Fertilizing a dry plant can cause root burn

I concur with Keriann; that kind of problem among multiple flats has got to mean that either you had a fungus in your flats or starting mix to begin with OR that you've somehow gone from sucessful seed-starter to causing damping off conditions since last year. Since you said you'd started seeds successfully before, it seems unlikely that you'd suddenly start over-watering or using techniques likely to cause damping off, unless you've changed your setup or location somehow. So if everything else is the same as years past, you gotta have had unsterile mix or containers. And sorry to say, no amount of No Damp or anything else is going to fix a systemic problem like that. I'm afraid your only alternative (as I see it) is dumping everything, sterilizing everything and starting again. Might get fresh mix too, just to be safe.

No one can give you a definitive answer to that. The maximum number of plants would depend on the plants, and how big their mature size will be. For instance half a dozen lobelia would take the same room as 1 petunia or Impatien.
5 is a good number if you are planting only Petunias or Impatiens, but then it would depend on the size of the basket. You can plant things closer in a hanging basket than you would in the ground.

Here is a good start on reading about leggy seedlings for you.

Here is a link that might be useful: Leggy seedlings discussions

I see on your other post on the Tomato forum that we are talking about tomatoes. They are quite leggy per your pic posted there. Tomatoes benefit from deep transplanting ASAP. Bury them right up to just below the leaves and then provide more, closer light or they will just get leggy again.

Funny thread. My biggest oops was last year's first time seed starting under lights. Everything was in the basement. I was pretty sure my set-up was good. But, why oh why, were my seedlings not taking off. Well, I finally discovered the outlets (except two) in our basement are all connected to the main light switch. So, when I checked on them, lights on. Back upstairs, lights off. The only thing that saved them was my boys' new xbox game that they kept sneaking downstairs to play!
Ali, that's hilarious! Frustrating, I'm sure.
