Yes, the rosebuds are coming directly from the bud union. I'll try to get a picture later today after the party is over. It has had the same attention as the rest of them. I feed them with Mills Magic Mix each spring and then during the summer I give them the Easy Feed??? I think that's the proper name. These products are wonderful!!
We had very little cold weather this year and since all of the other roses have been so pretty, I don't know if that could be the problem. I think anything is possible since the weather has been so erratic.
Thank you for your help and I'll get back later with a picture.

We are on "The Ridge" in Florida, which was the first part of the state to rise out of the sea. Very alkaline sand is our "soil". My flower beds don't resemble the soil found in our pastures due to the improvement of the soil in them, all done with horse manure, kitty litter, and wood chips.

One nice thing about an old lot on a slope that stops sloping before the end of your lot, just means some shoveling and a wheel barrow to get your fine top soil back.
The bad thing is you have to push all that dirt back up the hill. (Three guesses what I did today :) and those roses better appreciate it)
Last week I realized the downside of having amended the garden beds so well. I could not dig a strong hole for a fence post. The sides just crumbled in happily. Ended up pulling up metal posts (also too easy) and pounding them extra deep to attach the picket fence posts to them good thing the fence only has to keep out chickens and future grandkids. And will have a thorny rose to remind people not to lean too hard on it.
I wish I had amended the big rose bed more before planting. But no idea where I would want to dump that hard clay, so guessing it will just be a good place to layer more horse manure and oak leaves for the foreseeable future.


I found 2 websites that address the nitrogen testing problem. One from Cornell Univ. and one from Utah State Univ.
They are different, but the same. Seems as though N is too hard to test accurately.
Thanks. I wouldn't have looked any further without input from this forum. Now, as suggested, I will let the plants tell me if they require something.

Available nitrogen is transitory in the soil. Once it evolves into the nitrate form, it washes out of the soil. But with organic N sources containing proteins, bacteria are at work breaking them down and liberating available N as urea (which evolves into ammonium and finally nitrate). In cool, wet soils, there may be a temporary shortage of available N, because the bacteria need warmth and air. Also, if you applied compost that is not fully finished, that can cause a temporary shortage.
If the plants are actually short of N, the leaves will be an even pale green all over the plant. As Jim noticed, they are good and dark.

Ha...yes i guess i did know pruning it would make it grow...I guess what I WANT is the part that's already trained onto the arbor to do the growing, to reach the top!
Last year I seriously butchered the plant, including some nice looking canes, because I thought I had to destroy the powdery mildew. But it seems to be happy nonetheless.
That said I know nothing about roses as this is my first. I guess I was thinking that cutting the canes I don't have room for on the arbor would push the growth to the ones already there. I do not fully understand the growing cycle esp of climbers since I know pruning them is different. I will leave the canes...and maybe try to find a place for them, or whack them back later?

ZD makes tons of basals. Mine was like a bamboo patch. with 20 or so 8-foot canes after a few years.
The old basals, insofar as they are semi-horizontal, will bloom heavily on laterals, and this will provide the early bloom. Then, if you let the new basals grow and bloom, they will prolong the spring flush into mid-summer, blooming at the top. Then any later bloom will come at the tips of late-starting basals. In other words, ZD does not repeat very well on the old canes, but the new canes help to compensate for that. At least, that is how mine behaved.
I fear your arbor is too small for such a lusty grower. But I'm sure you want to give her a fair trial. If you want to contain growth, here are some things to try:
Withhold water and fertilizer starting at midsummer, because you aren't going to get much late bloom anyway. Let the new canes grow out and bloom. Don't prune them out in summer, because the plant will just replace them. Next spring, cut some of the canes back to various lengths (2'-4'-6'). These will make blooming laterals at the various levels for the spring flush. After a few years, when you have too many canes, begin removing 1/3 of the canes, older ones, at the base every year. I would do this after the old canes have finished their spring bloom.

For in between, how about some daffodil & narcissus bulbs? Deer don't eat them - really - they are evidently poisonous. I have even had squirrels dig them up (this is only within 24 hours of them being planted), and then leave them untouched on the surface of the soil.

I have a 20 year relationship with RDV, so I couldn't bring myself to tossing it. I dug a hole in the slope where I have my other old garden roses. I dug up the RDV and there was a large, deep tap root so things didn't go well. I put it in a bucket of water and planted Peace in the hole. Things went well; plant and soil came out of the container undisturbed and the plant wasn't root bound. I took the soil from the hole and mixed it with soil conditioner and planted RDV bare root in the container Peace came in. If it survives the summer, I'll transplant it next winter.

catspa, unless said noisette is blown down during a storm and has to be cut back to almost nothing...then you should see the new growth sprout up! I hated having to cut down my Reve d'Or before it bloomed, but the bright side is that it did have a lot of gall on one of the largest canes, so I got rid of that.

Buford, I wouldn't doubt it! (I was sorry to hear your report of this mishap, by the way, in an earlier thread.) The vigor of a tea-noisette that's doing well is a force to be reckoned with. I prune the MAC on the west side of the house really hard every year (taking off whole canes -- not, heaven forbid, by shortening them!) so the path doesn't get totally blocked. She responds to the insult to her quest for world domination with ever more vigorous sprouts -- all over, but the ones lower down tend never to make it to the sun and die. Ditto Jaune Desprez, also along the west side alley and pruned pretty stiffly every year.
Anyway, here's this year's picture of the MAC against a north-facing wall that has not put a basal up in years:

Here's the MAC on the west side of the house whose sprouts from the lower half of the trunk pretty much never survive:

Here's Jaune Desprez where, again, sprouts from the lower half of the trunk rarely make it up into the light:




Andrea, you can still mulch, etc. if you plant the under plantings a little away from the bottom of the rose. You don't really want anything right up against the base of the rose anyway. Just plant something out a foot or so away and it should be fine and mask the problem. I use mini roses sometimes to do this but you can use anything, perennials or annuals for that matter.






Yes. Definitely burnt. NOT blackspot.
You're in the Antelope Valley? Here at the coast, we've had two sieges of high wind, low-humidity, and abnormally high temps. I'm assuming the desert was NO FUN. I'm not surprised foliage burned -- even if you HADN'T sprayed it with anything.
There are good images of blackspot on roses, at the link below. I always think, it looks a bit like someone dropped dark ink on a paper towel. You're unlikely to have it, in desert conditions. (Rust, yes. Blackspot, no.) But this is DAMAGE, rather than disease.

Bingo! Jim, in our heat and sun, it's always a great idea to make sure all the plants are as heavily watered as possible before using any fertilizer. Then, water that fertilizer in well after application. This year is even weirder than last with heat and sun spikes. As long as your drainage is OK, you can't water too much for the plant in our conditions. You CAN use too little, particularly with any fertilizers and other "chemicals", especially in the next four to five months. Kim
