When in doubt, ask...

18 years ago

My beautiful, leafy Burgundy Iceberg now is not. It's full of buds, but the middle of it has been defoliated by blackspot. Gee, and it was doing so well - in the drought. Now the rains have begun (I hope they stay), and this is what BI looks like.

{{gwi:298972}}

My question: when this flush is over is there a right way to deadhead that will encourage leafing out down low on the plant? This is a first in my rose journey, so I don't know if I have to live with naked legs from here on or will he leaf out again? Do I deadhead down to the next outward leaf or should I be a little more severe?

I know this is basic stuff, but since this is only my 2nd year of roses and they're mostly OGRs, I'm stumped.

Also, his buds and flowers are quite small compared to earlier flushes. Anyone want to venture a guess as to why? (Our temps are in the low 90's.)

(BTW, he's in a pot because he's on the wrong rootstock for Florida.)

Thanks!

    Well he (the rose) doesn't LOOK embarassed about his legs....

    You could always underplant for now, just stick in some cheap annual heat resistant bedding plants to hide the legs. Presto, instant modesty.

    Yes, higher temps will definitely make for smaller buds, or so I understand. Water water water I guess.

    How big is that pot? I would consider moving up to a bigger one. That and some fertilizer should help it add more foliage, but you will probably have to spray with fungicide lest it get BS again soon. A harder pruning if it has suffered recent BS pressure may not be a good idea.

    Is it related to regular Iceberg? Because that is a BS magnet. You will not be able to grow it without spraying.

    I've found that after defoliating from BS, most roses will not put on many leaves on old growth. So I would prune it back hard after the flush is over if you want a full bushy looking plant.

    Whoa! Conflicting replies!

    triple b, he's a very brazen rose. Not embarrassed at all. I water him daily, so I will keep it up. I don't think I'll underplant. I put chives in this pot with another rose last year and wound up with a pot full of chive roots and NO rose roots. Amazing!

    hoovb, the pot is almost 24" in diameter (22" or something like that). Only in the pot since March, I think. I just fertilized again on Sunday. Perhaps I will just do the same deadheading I did last time. I took off about 6" all the way around. It still looks vigorous, but I don't want to stress him if he could be feeling poorly from the BS. I don't spray.

    buford, Burgundy is a sport from Australia, I think, and it's SUPPOSED to be very disease resistant. Not like Iceberg (but go figure, my Iceberg in the ground has not gotten much BS. I admit to being very sloppy when watering lately, thinking this rose is bulletproof. I splashed a lot on the lower leaves.

    If I wind up having to yank this rose, my DH will beat me over the head with it - in a nice way. I hope to avoid that confrontation. LOL :))

    Unless it puts up a bunch of new canes from the base (hiding the bare stems thereby) I doubt you'll get coverage of the bare spots now.

    I put a very small bunch of chives in each rose pot and until I ran out of chives and kept adding rose pots. Maybe it is the weather, the particular rose, or the chives but I have not had a black spot issue to speak of.
    Thrips, aphids, whitefly, yes. (nasturtiums in the rose pots didn't work for aphid control but I have never had nasturtiums grow so big and healthy.)

    Maybe give the rose some alfalfa tea?

    That pot is too small for that rose... In either case, since it's on the wrong rootstock and you know it gets BS, get a bigger pot and get another rose :)

    Midnight Blue is a similar color and stays more bushy...
