Lack of enough moisture and too much sun/heat can prematurely result in browned out blooms.

And then there is Fall approaching too. ;o) They may just be browning early this year?

Make a note in a wall calendar to monitor moisture starting July 2018. Maybe?

Compare with someone very close by, someone who gets the same rainfall and weather conditions as you.

Hi Lala,i have a couple of BB's that are also 2yrs in the ground, one gave me 5 blooms for the yr and the other bloomed great, both in sun ( 8hrs) the one with blooms is beginning to look tired and the leaves are start to yellow...we are in the same area

Yeah, looks tired. But the plant to the right is a tad more tired looking, bloom wise. What is it? Can you get more of those blooms if you deadhead it, hyed?

Luis, perennial Blackeye Susan, it's about had it for the season

I saw it at a plant nursery or Walmart last year and thought about getting it but didn't. Does it self reseed for you or come back from the roots? Seems nice besides Bobo.

Luis, you can grow from seed or plant, they will spread and grow quickly

hyed, our Bobos are twins--that's just what mine look like too. I had been hoping they would get rosy in the fall. I guess not?

Use something like straw mulch in spring. It's very useful in helping to keep plants with even moisture.

Thanks rouge, mind starting to pink up ... but I think they all look the same

Ialala, here is one of our "Bobos" as of October 22. The ones in full sun have crispy brown flowers but those, like this one, which gets some reasonable shade during the day have looked much better for much longer:

Beautiful! Thanks!
