Warren where are the seedlings now, what fertiliser are you going to use and at what age are the seedlings fertilised firstly? Are they out in the open, frosts etc or under glass or plastic?

You seem to have a good system pollinating the first month of blooms so hips ripen early autumn then into the cooler to germinate May June July so they have a long growth period of warm weather.
I notice you get extremely good growth from your new seedlings which in past posts you accredited this to spray fertilisers like Thrive etc.

Do you use the kiss method or finger-brush pollination methods and which works best for you? Do you pollinate two days running to be sure?

A little more information would be appreciated by everyone, beginner or old hand at breeding.

Howdy Bruce,
All seeds after stratification are planted in 2"tubes, roughly 10-12 per pot and around the side only, I found it makes it easy when pricking out and less damage. All seedlings are transplanted into individual 2" tubes with a few grains of osmocote about half way down, dont over do the osmocote. The soil media I use is a commercial one I get from friends of mine in the nursery trade, transplanting seedlings on I use 50/50 of their propagating mix and potting mix. Drainage has to be good but at the same time hold water and nutrient. They are fed with 1/2 strength Aqusol or Thrive every week for 9 wks again don't overdo the dilution otherwise you will burn the roots.


All the seed containers and transplanted seedlings are placed in the open and bought in at night, I find this hardens them up right from the start. When I decide what I am going to keep from the tubes, every thing is planted out in the grow out beds in late August.
I plant them in rows which has a line of fertilizer 6" below the surface, again every thing ferilized every week with 1/2 strength soluble fertilizer untill I feel they have tapped into the underground fertilizer source.

These are seedlinges in 2" tubes 9 wks old



The seedlings planted out in August 2010 grew to these by 28th December 2010


Bruce I pollinate using individual brushes for each pollen, and then washed out with very hot not boiling water, I dont use my finger as I feel it could lead to contamination of the stigmas with bacteria or fungus which effect the fertilization. I know a lot of the big breeders still use their finger but that is me being cautious.

Warren, that method you use to grow your seedings will go well with the ways people stratify thier seeds. For me what I have started is a little folder on all the suggestions of how to propagate and raise roses. We have one grandson becoming interested in plants, so will keep these notes aside for him incase the inclination developes further, thanks.

Warren, that's pretty amazing growth from germination to blooming in 6 to 8 months. Will have to to change from planting newly germinated seedlings into peat pots then when the roots appear they go into 6" pots outside.
I haven't been feeding as frequentlyl as you.

I posted before mentioning I was using Henry Kuska's methods to germinate in clean beach sand and small flat plastic containers. Fluid is 5mil 4% Peroxide in 80mil of water which really shows the moisture content extremely well. You must have a large cool room or bank of refrigerators for that amount of seeds. I have a medium refrigerator and have had great difficulty fitting the lot in.

Thanks for your comments.

Bruce,
You asked the question I was going to ask and Warren you gave a great reply.
Very insperational, I am going to try again with my seeds.
What fantastic growth you get in just a few months.

Getting pretty excited , seedlings are germinating every where, all the HT crosses with what I have bred are looking real dandy, also the HT crosses with pre 1900 roses are popping up. I will be pricking out seedlings to be potted up into individual 2" tubes next week, and then see them grow. I cant wait untill August when they are going through their bloom cycle and finally see if I got what I was after.

Warren, any chance of a mention of one of the pre 1900 roses that you have used, please.

Sure Dave, off the top of my head, lets see,

Lyon Rose (this is 1907)
John Hopper
Grace Darling
Baronne Henriette De Snoy
Duchesse D'Auerstadt
Mrs John Laing
Gloir De Dijion
Mme Caroline Testou
Conrad F Meyer
Comte De chambord

I think thats about it.What I like to see is the different colours in the cotyledon leaves in one cross, it tells me that there is a variation of traites being passed to the offspring.

Warren the one's that I like out of your list are,
Lyon Rose (this is 1907)
John Hopper, I like it and it's background
Grace Darling
Baronne Henriette De Snoy, something nice will come from this rose I think
Duchesse D'Auerstadt, this is on the wish list for later
Mrs John Laing
Gloir De Dijion, have always admired this rose, but never bought it, yet.
Mme Caroline Testou
Conrad F Meyer, definate starter
Comte De chambord, would this cross over any of the above ?

What I read about some of the family tree on some of these looks interesting to say the least, can't wait for the flowers now.

I really look forward to seeing your offspring from your crosses too, Warren.
Your planted out babies look amazing. Thanks for showing us and telling us your method.
David, I have Duchess de Auderstaad. You could have a little budwood latter in the year.

Thanx Rosemeadow, have a good feeling about this year. The soil is pretty good here, roses love it. This is how good the soil is , I grow sweet potatoes and this is how big they can grow, these were planted out from cuttings late spring last year. I think you would get enough chips out of one to feed an army. They average 9kgs each.

Howdy All

My Sympathie x Rosa forrestiana seedlings are popping up everywhere, as far as I know and HMF, no one has used this species in any breeding programme with recorded offspring. Absolutely beside myself at the moment.

Well I've got last years seedlings germinating. I've had the odd seedling come up during summer, but I lost patience with this lot and tipped most of them out by autumn. The one punnet I didn't touch had 4 seedlings in it when I looked yesterday, plus another one in some recycled soil in another pot. There's a moral there somewhere.

Now I need to plant all this year's seeds. Most of you are way ahead of me!

It's Sydney Linton x Louise Odier. I must have been dreaming of some pinky mauve shades.
