Here's an image and more information from Floridata. I guess it is also called Malvaviscus penduliflorus. I'm going to experiment with sowing the seeds when I get a chance and post my results.

My newbie mistakes last year were big ones! I felt like an idiot! I did the sowing flats for some seeds, none survived that, still dont know why. But I used a 4" deep round plastic tray w/ potting soil to plant moonflowers. No drainage holes, and only 2" of soil!!!! They actually popped up great, grew to about 3 in tall, then died!! Gee...could it be because of the lack of room for their roots?? LOL!! I had 7 butterfly weed and 5 magnus purple coneflowers survive. Planted them in styrofone cups, once again no drainage, must've been lucky. I also didn't harden them off. So I was REALLY lucky.

One thing I have learned (not a newbie but always learning better ways to be successful)I always wet my soil completely before I set the seed. I do this because it seems the soil has a tendency to soak up the water in certain areas and not the entire surface. If you start iwth wet, not dripping soil I think you have a better chance of keeping it moist. I use the started trays with the little net wrapped plugs, I soak them good, place the seed, cover it with the lid and when they start to sprout I remove the lid and let them go. This year I did sweet peas, climbing blackeyed susan, impatence, asters, bach buttons, marigolds, cosmos, they all did fine, they are in the ground already. Drainage is key! Set them in the shade for a few hours a few days or week before planting them out. They burn easily and dry out fast when placed outside so keep an eye on them.


They are under a "natural Light" fluorescent bulb, 48" long, with my other seedlings. My husband said that he thought that I had the light too close. It was less than four inches from the morning glories. The other seedlings are all so much shorter that I was hesitant to move the light up much higher.
I have now. I just hope that they are able to repair themselves, if that is what the problem was. The new leaves are continuing to grow well.
Also, I had the light on for 14-16 hours a day. Is that too much time for the flower's needs. The veggies are all very happy.
Thanks!

I am zone 4 and my soil temp was 69 this morning! I have my sun flowers in already, some direct sown some prestarted in the house! Sunflowers are an annual but often reseed themself so I KNOW that a chilly soil does not harm the seed, it will just not grow until the soil warms up! I say plant them...when the soil is right temp they will show you!!!

You can absolutely start sunflowers now. We grow a couple acres of multiple varieties of sunflowers. We direct sow the first seeds in mid April (not this year because of the unusually cold temps) and continue every two weeks through the beginning of Sept. Our fields have rows covered in landscape plastic so it gives us a couple extra weeks on either end of the growing season.

Lately I've been having my moonflowers sprout the next day (I nick, soak in a cup of water for a few hrs, then do paper towel/baggie method)... but I have the paper towel/baggies all sitting on a seedling heating mat. Personally, I have found the paper towel/baggie method to work with everything except tiny seeds - I don't use it for papyrus, vaccinium, or basil - too difficult to remove the tiny little rooted seeds from the paper towel! For those I just scatter them on top of damp peat and put that container (usu. a small yogurt container with slits cut in the bottom w/scissors), and put that into a baggie for humidity.

Could this be sunscorching?
Yes. That and the effects of the severe light/temp change. Just like we humans. :-)
It affects the most established plants the most because there is more there to get ~shocked~ ;). If not too badly damaged they will recover but baby them, a little misting (feels good on a sunburn), keep them inside or under cover until they do and no feeding.

That sounds right to me, too. Actually the other marigolds are turning purple, too. The seed leaves for both the 2 foot and 6 inch marigolds are purple withthe larger ones more affected. The zinnias are completely fine though-- but then again, they are not dealing withthe seed leaves thing. Does that put stress on plants? Also how do I keep them covered if they are in a 72 cell tray with others being hardened off?

It's true. The division size depends on how big the old clump is. I usually go for cutting in half but you can do thirds or even fourths on really big 3' wide clumps.
It is best done when the plant is dormant, use a very sharp knife to slice vertically down through the plant, root ball and all. Re-plant the divisions and water well.

And yet another cold start captured by the bad guys not yet controlled by a warming soil. You may replant but I would use some potting medium in the hole when you do. By the time you are ready your soil biology will have ballanced itself and will very likely take care of the problem. I have a lot of early start friends in the same boat. They are starting over just like you. Cold soil very often presents this problem. Not much good goes on until the ground temperature is at fifty degrees. It gets better from there on as your soil warms.
Remember the only consistancy in gardening is the very inconsistancy of it all. Being a late starter this year may not be all that bad.


I have wisteria seeds that came from the pods on the VINE. I'm not sure what you mean? Wisteria is a vine but with constant pruning of the vines it can be trained as a tree. It will still produce vines that will have to be pruned to maintain that tree shape. But it is still a vine. Or are you thinking of another plant? I haven't come across a vine spelled wYsteria instead of wIsteria. If there is another type of plant/vine w/that name Id be curious to know.

Maybe for some, others should be ok. I started a lot indoors earlier but couldn't do them all. What I am doing now for some is planting them in covered things outside and watching them like a hawk. When they germinate, I take the covers off and either mist or bottom water because I cut slits in the bottom of the containers (McDonals's covered salad dishes). Then I will only have to transplant on cloudy days and not have to worry about hardening them off at least.
Many I wanted to just sow where they are to bloom, I started a thread about that. I can't start and transplant everything like I said above. Despite 3 days of heavy rain last week, the sun has baked the surface of the soil.

The ones I am starting in containers outside, I put in a shady spot until they germinate, then move into a sheltered spot where they will get a lot of sun but not cook in it all day. Later they can go in full sun. I will transplant the seedlings into little plastic cups with a slit cut in the bottom, put in some pans I got at the dollar store, you could use dishpans but I couldn't find any cheap enough.
Then I will put them where I want them. I feel I have a little better control that way rather than planting directly in the ground for some things.
I am just kind of winging it. I got some shop lights for other things like propagating cuttings later and some seeds. But there is a limited amount of things you can grow that way unless you have shop lights all over the place.
I found out the hard way, they get leggy if you use an east window. The ones I started in south windows are doing a little better, but I have to keep turning them.

In certain plants, what we think of as seeds are really fruits with several seeds inside. When these are small and hard, it's impractical to get the seperate seeds apart before planting. The common garden beet is a fine example. When you plant beets, you should really thin them after germination even if you have spaced the seed, because you mostly get multiple plants from each "seed".

There are plants that produce polyembrionic seeds with more than one seedling per seed - citrus commonly do this. It may happen more often than you would guess, often the dominant seedling takes over and the weaker dies off. But I couldn't begin to guess the frequency in which cerinthe seeds are polyembrionic, my education doesn't extend nearly that far :)
Some time back, someone posted very clear photographs of a polyembrionic hellebore seed with more than one surviving seedling, very interesting.


I had to pinch a few bad leaves myself, they were just not looking good,on about 5 plants out of 100 (I start them for myself, firends,family and neighbors)!!So.....I pinched them a few weeks ago and the plants are doing fine still, they did not show excess growth due to the pinching, nor get stunted. They are keeping up with all the rest just missing a few leaves!So......I am assuming when a leaf looks bad, no matter where on the plant, pinch it!
AND yes...save those seeds for next year! Seeds can last MANY years! Hence the heirlooms!
Happy to report..after pinching, tomatoes are still looking great. Like rdubow, mine don't show any excess growth or stunting. Very healthy, and anxious to go in the ground. I'll be planting soon...
