Default Dying new growth

Thanks Allegra, I have hope now. Well since you ask here's what is planted
and still to come:

In the ground: Bride's Dream
Climbing Pearly Gates
Fragrant Cloud
New Zealand
St. Patrick
Whisper

Waiting to arrive: Mellow Yellow
Aint She Sweet
One I can't remember the name I ordered ( getting
old )

Still to propagate: A fifty year old Red rose from my Mother's garden that
was given to them as a house
warming gift.

My wife and I bought this house a year ago and I'm re-doing the whole garden
to resemble the garden
that I grew up with. This is only the start. I've grown roses for a nunber
of years but never bare root.
Thanks again.

Rick

This year I bought 6 bareroot roses from Edmunds. I followed the

planting
instructions to the letter for 3 of them. On 2 I did the same except

for
mounding around the canes and on one, left it a bucket of water for a

week
then just planted it. Of the three that got the mounding around the

canes
I
waited until I saw 2-4 new growth popping out before removing the mound.
There was alot of new growth under the mound, blanched from no sun. The
growth outside of the mound is doing wonderfully but the growth under

the
mound has just died off and no new growth can be seen from those canes.

Why
would this happen? The
2 roses that never got the mounding have alot of new growth and are very
healthy. The one that got left in the bucket of water for a week is

doing
just fine also. Maybe mounding here in So. CA just doesn't need to be

done,
I have no idea. Can anyone explain to me why the mounding roses new

growth
has died off and is there anyway to get them jump started again to get

new
growth?

Thanks to all for even reading this post.

Hello Rick,

I cannot tell you for certain why the new growth died,
but I have my suspicions. Roses are covered at the graft
in colder areas of the country to avoid cold damage to
the tissue where the graft has taken place. If that part
of the rose - you know, the bumpy little bulge between
the canes and the trunk of the rose - dies, your rose
reverts to the stock that was used to graft it. In the
west it is likely to be our good Dr. Huey.

In our side of the country not only isn't necessary to
cover the graft, but actually is better that you don't.
Your rose got the message from the light and the
temperature that it was time to break dormancy.
The warmth of the soil and the light that helps
to develop photosynthesis which indicates to the
plant that now is the time to spread those feeder
roots and get going, was short-circuited by the
soil on top of the bottom of the rose. It pushed out
in hopes of reaching the light that the upper part
was getting, and thus you got growth under the
soil. But it didn't develop the same tissue as the
leaves exposed to the light, the warmth and the
air that the rest of your rose did.

When it finally did, the connecting tissue was way
too thin to survive UV rays and its burning effect
plus the dehydration that comes from thin tissue
and lack of exposure.

Don't worry; your rose is not going to die. In a
couple of months she will perhaps comeback with
another batch of leaves and if you make sure
that continues to be well watered and fed, your
rose will be just fine.

Remember that there is no reason to cover the
graft here. You may plant your roses with the
graft at ground level or even a couple of inches
above. That will allow mulch to insulate the
roots as well during very hot weather.

What are you growing? Rule of this place is that
we tell, spill, account for, you name it, but we
name names. Hope this helps, and good luck

Allegra
