I grew only Mammoths last year. I sowed them in 9oz cups about the first of April. They germinate quickly and are a lot like tomatoes. They can't handle any frost, so you may want to wait a bit more. When they start growing, they take off quickly. I dig a deep hole and plant them with just the top leaves showing. This helps them form more roots along the stems, just like tomatoes. The taller ones need the support more than the short, multiheaded varieties.

I'll be sowing mine tomorrow using this same method again. I have a nice variety this year including some red ones.

Thank you token,
I will look for several different kinds this week.
I think I may like the shorter ones.

I WS sunflowers this year before I figured out that some things should actually be spring sown. I had a bunch of sprouts that quickly outgrew their containers. So, I actually planted some out very early. Last weekend they survived (with flying colors) 26 degree temps two days in a row. Since they do sprout so quickly, I wouldn't hesitate to start some early. My two cents. I am growing some "Evening Sun", "Mammoth", "Teddy Bear" and "Dwarf Sunspot." All of the sprouts haven't been bothered by the freezing temps for a few nights--to my surprise. You could also consider using 2 liter soda bottles as cloches.

I didn't sow mine today. I'm still waffling back and forth between direct planting and sowing in containers. I've got more squirrels this year than ever and they're doing some major damage to the gardens.

Ive seen them handle some light frost.. anything hard and they are gone.. I sow them around now, I just plant them near may 1st.. thats not my last frost date, but I usually do not recieve anything too heavy, but if you do, just cover it , anything will do, sheets, a few pieces of newspaper, or save your top of the milk jugs and cover with that.

Just keep the frost off, they can handle cooler temps fine...

Lots of good advice here,thank you,I think I will sow them in soda bottles,now,I can always bring theminto the garage if it gets to cool at night,we have had some really beautiful weather this week,60-70-and 80.
I have lots of sprouts, finally,:0)
I sowed some Delphiniumes two weeks ago,kept them in the garage, with a cardboard on top, I read they needed dark and cool to germinate, looked at them today, and yeaaaaaaaaaa,a few sprouts, I was so surprised,I though they needed cold strat., but it has been to warm, so I guess not.
I am still waiting for my Ech.nothing yet.
Tomorrow, I will sow my sunflowers,after I make a mad dash to Home Depot to get them,I just LOVE,Home Depot, gon't you guys.

The Tithonia - mexican sunflower - will not handle any frost at all. The Mammoth and Black oil sunflower handle a light frost okay. They are also very easy to direct sow and sometimes reseed themselves. Cutworms, slugs and critters like sunflowers - so sometimes I protect them with cups.

2 years ago my mammoth sunflowers grew in the middle of a perennial bed and they were HUGE (10-11 feet). I wasn't thinking, they were towering over the perennials. Now I grow them in a "tall bed". The birds, squirrels, and chipmunks love the seeds!
