If you don't have much time or don't have a green thumb try growing sunflowers. They area very easy to grow and fast growing. This one is in an old cast iron pot on my porch. They come in a large variety of colors. I purchased my seeds from eBay. I also put in some broken pieces of vintage pottery for drainage and color.

This is my first year to plant sunflowers in containers. When cold weather sets in what should I do?

Is your variety an annual or perennial? If it's an annual, just pull it up in the fall, and start fresh in the spring (or, you can leave the seed heads for the birds to eat over the winter). I've never had perennial sunflowers, but for our other perennial plants, I cut them back in the fall/early winter. If you're in a very cold area, you might want to pull the container inside, or put it in some other sheltered spot.
If you're not sure what kind you have, take a look at this article, it has some helpful information. Best of luck!
If it's a perennial sunflower, plant it in the ground, it will survive better. Plants in pots do not always survive, they freeze easier and get colder in cold and wind. Good luck. :)
I planted my seeds and they immediately started growing. It says "trim" at 4". I don't know what "trim" means.
Next, where do the sunflowers bloom. All I have right now is really tall green plants, but no blooms. I'm so lost.

Trim? I have a package of seeds and on the back of mine it says "thin" when they are 5 inches.... They will not bloom until they are full grown. depending on the type, they could be 12 inches to 12 feet tall. They must have full sun to grown, and can not be in a crowed pot.
These are too close together. You need to cut back the ones that arent as big to let the big ones flower
Does anyone have an idea how a sunflower can grow stronger and faster? Please help. We have very strong heavy rains here.

I bought sunflowers at a nursery and they were beautiful. However, they have already died. What did I do wrong?
I planted sunflower seeds in a pot on August 12 and watered it. Now it is August 15 and I tried to dig them up to see if it is already sprouted and it is! But now there's a very, very strong heavy rain. I know that a sunflower needs to be under the sun to grow. What should I do? Does it die? Or what? Please help.
Sunflowers need rain to grow too. If you think they will be flooded and the seeds washed away, just move the pot to a protected area until the rains have passed.

I am going to grow sunflowers in an old wash tub. Do I need to put some holes in the bottom of tub for drainage? Does it need to have rocks in the bottom as well?

Yes, drill some holes in the bottom of tub for drainage. And as for the rocks, they aren't necessary. (03/31/2010)
I've never tried them in containers, but I don't see why they wouldn't do ok! They don't root very deep, so any container 10 or more inches deep should be fine! The lady in the above article was using an old washtub, with drain holes in the bottom. I think it'd be an even better idea to have something underneath the container to catch/hold the water, so it can wick up through the soil if the soil becomes dry.
If you're using a big container and don't want it to be so heavy you can't move it, use empty pop or water bottles (with lids on!) in the bottom. The dirt will filter down through/around them, so it'll still wick up moisture from your drain-pan, but the pot won't weigh a ton, like it would with rocks in the bottom! I've done this in a huge pot, and it works well so far--2 or 3 years. Good luck! (Oh! Make sure your sunflowers have stakes if they're going to be exposed to a lot of wind!) (04/01/2010)
