I have tried to grow it here but it does not stand upright and does not grow well..
Is it too hot in zone 8 lower areas , too humid?
It grows in Atlanta Georgia really well where my mother has it in her flower bed
at her home..but here it does not live..

Bee balm was always a problem for me it would die, mildew and I tried again this year and I have kept it moist..and I think that was the secret along with
whatever type it is.. maybe mildew resistant..no name on it when bought at lowes
last spring.. I have beautiful bee balm ..the plant is green and healthy and we are to turn down to 24 tonight..it will not be pretty and green tommorow..
any thoughts on growing yarrow in a humid hot climate like lower zone 8 in
alabama?
thanks

I find yarrow likes full sun, and can certainly take the heat, but in my area it needs lots of water to keep it alive. Too dry here with almost 6 months no rain usually..It should not be a problem I think in your area. If it is a young plant, it will have to be watered a little more often first year to be established and use porous, well draining soil.

I almost killed mine, thinking it is drought tolerant right away so it should survive well the way I water my other succulents. A sudden rain later showed me that it likes more water and I have been underwatering it after all. Then my next mistake, I should have deadheaded it after blooming so it can reallocate resources to grow again. Now that I knew about it, it has slowly returned.

I find it interesting that a friend in Seattle was somewhat horrified I grow yarrow! Perhaps her mild climate allows it to be invasive? I am in Z. 4 in WI and love it in my mixed perennial beds including one large hillside one. I just wish the newer cultivars would propagate more rapidly.

thank you for sharing
I found that bee balm likes moisture and more watering here
and that was my answer on growing it here...
so maybe Yarrow is the same for me ..
in lower zone 8.

I have morning sun only on that area..that might be a problem

I live in zone 5b and also have trouble with my yarrow not holding it's head up. It's also hard to stake, because of the feathery outer leaves. My yarrow doesn't get strong, direct sun. A maple tree is nearby-but doesn't hang over the yarrow. This is on the east side of our home.

Hi Sheri,
I am in zone 8b as well and have had good success with yarrow. About two years ago, I grew two plants from seed. This is the first year they have bloomed. I have them in a partly sunny area, facing North/Northeast. They require a light-mild watering 2x a week or a more thorough watering 1x a week. One is straight, the other has spilled over. I may divide that plant this fall and give it some support for next year. But the blooms are absolutely beautiful and have lasted a long time. I took these pictures about two weeks ago and since then, more blooms have appeared, making the yarrow more full. I encourage you to try yarrow out again. I'm in North Texas and it can get quite hot and humid. Yarrow has proven to be a great plant for me, given I started my plants from seed and they've only known this climate. I regret not planting more. Their beauty is best displayed in mass planting. I've started 12 more plants from seed and hope to have blooms in a year and a half. It's worth the wait for me!
