I've mulched and water daily, but am looking for alternatives as I think they're still getting too much hot sun in July and August (Zone 6b)

Also, are there any varieties which are more resistant to to full-day, hot sun?

Hello,
Couple questions:
What kind of clematis do you have?
How much sun does it get and why do you think it is too much sun?

I usually have another plant in front of it, I have many of mine planted at the base of roses and shrubs.

Apologies for the much delayed response. I just saw your message. My clems face south and they get full sun (9-10 hours a day). They seem to be doing much better now that the temps have cooled a bit and I'm paying more attention to them - one of them has actually rebloomed. I have 4: Miss Bateman, Elsa Spaeth, Piilu, Gillian.

I seem to be dealing with severely crispy leaves each summer. This summer was also extremely hot with very little rain. I know better for next summer (daily watering necessary), but I'm wondering if some varieties do better in full sun than others.

Clematises shouldn't require daily watering. Where do you live? Put down a 3" layer of mulch to keep the soil evenly moist.

SE Mass. I'll be revamping next spring and will follow your suggestion. TY.

First of all, I completely agree with Arlene - no need for daily watering. Your clematises are from large flowered group. From my experience they almost all getting crispy leaves in the summer. I have mature Nelly Moser in full sun. The roots are between azalea bushes. Classic position! I am in Seattle. Good, not so hot summers... and crispy leaves . My viticellas doing much better in full sun. Also Texensis group likes sun from ground up. Montanas never loose any leaves. (I am not sure if they can grow in your area). Integrifolias like sun.
You can try to cut your clematises after spring flowering in half and fertilize. The leaves will be much better plus good second flush of flowers. If you going to move your plants try grow them through different bushes. I stated to grow mine through rhododendrons and hydrangeas and now I am very happy. I don't see the foliage just flowers popping here and there

I agree with Luda. My clematis Anna Louise grows through a nearby hydrangea and it blooms happily.
