I have 3 butterfly bushes..One did the same a month ago in July and it was
HOT and humid.. not too much water...in the soil to cause it
It dropped its leaves they turned brown and fell off...

I cut it back to 15 inches and it is now putting on tiny green leaves on that
bush Miss Ruby

Miss Molly is turning yellow and leaves brown and dropping leaves and I know
it is not too dry or over watered...it has afternoon shade but half day sun
and enough moisture..the Miss molly beside it is green and doing good
green and not dropping leaves and not yellowing..

It has been 104 heat index here for a few weeks...
temp in the 96 -99 range...but they get shaded in afternoon ...not in the burning
sun all day

Do you know what I can do and what is causing this to happen..

Hi Sheri. I saw this post and wondered if you had figured out what was going on with your Buddleia. Looks like one of the leaf spot fungal infections. Have a look at this link.

just saw your reply..

I come on here once a week

I put the liquid fertilizer to all 8 bushes twice now
in about 16 days time..

Mixed as directed...bigger middle number....liquid
in bucket of water per bush.

IT has encouraged some new little leaves near the base....
due to my doing this

The streaking is still on all of them ...some yellow leaves dropping
some still mottled leaves..

We are due rain 4 days this week again..and it has gotten to 105 heat index a few days
my flower garden ..fortunately gets sun from 9 am to 3 pm ...then afternoon shade.

The woods protect it from winds...

Will include a picture below...of it in late May and one in July...

May is prettiest month before that scorching heat comes with high humidity

we had more rain this summer than in about 22 years..
the perennials do not stand in rain..it drains well...

Glad they are recovering. Neat pics of the wild life.
