I have never grown Hosta before.I have some H. 'dream queen' and my question is when i plant it in the fall how do i pick a good place?Right now the days short & sun's not blazing but when picking out a spot i have to remember we have blazing hot summers and haven't had enough rain in years.So when picking out a place should i go with sunny place now but that will be partly shaded in summer?How much sun can they take in the summer and what's their preference as to soil drainage,quick draining,dry quickly or do they need to have a water source a little longer?We are still having temp's in the high 70's during the day!! We usually don't get cold until Jan.-Feb.if planted now they should be well established in time just in case we do get any cold weather.

JoJo, go ahead and plant where there will be complete shade. Even if it says sun tolerant it can not take our heat. They need as much shade as possible. Remember to water regular.

Susan, thanks so much.I learned the hard way they really are a good shade plant.I had put a couple things in the wheelbarrow for a rock garden i'm putting together or i guess it's just coming together as i get new plants,rocks,driftwood etc... anyway i didn't notice my loving helpful hubby had put a pot of Hosta in also.I left it at the rock garden & i notice that the leaves are yellow.

Will the plant be ok? I'm hoping it's just sunburned and will recover!!! I have about 5 that all have what i guess is a flower bud growing out of the middle.

Are these plants good to use as a tree line bed.I am wanting to get the different ones with the different colors & sizes and plant them accordingly. They aren't easy to find around here in the garden centers but i haven't really been looking,but i will start.

Don't worry about moving it now, it needs to settle in for winter. Mine are all yellow also at this point and it's just the cooler temperatures at night.
I do have problems finding nice Hostas around here, I have been doing mail orders for a few years and I know of some good companies. I posted pictures under my recommendations. Like I said choose sun tolerant Hostas and if you want to avoid some headaches get slug tolerant when ever possible. If you have something delicate that gets munched a lot you can always put it into a nice colorful pot and just sit it in the bed that way.
Yes you can plant them under trees as long as the tree roots are not in the way. I have a raised bed under the tree and that helps, Birch trees have awful roots.
