Summer cuttings update

| I am pleased to report that my experiment with summer cuttings has been quite successful. My results with cuttings taken mid-December are:
Crocus Rose - 1 successful strike out of 3 (33%)
Ambridge Rose - 1 successful strike out of 4 (25%)
Leonardo da Vinci - 4 successful strikes out of 4 (100%)
I have to say I am delighted with the results as all my previous attempts to strike cuttings in winter have been rotten failures (although I know it can work). It seems to me that it makes more sense to try cuttings during the warm weather when the plants are naturally in a growth phase rather than during their winter dormancy. My method was simply to place the cuttings in a pot filled with standard grade (black ticks) potting mix, no hormone powders or wounding the base of the cutting), place in a shady spot outside and water nearly every day.
I am also guessing that Leonardo da Vinci which seemed to strike so well may in fact grow and flower better on its own roots compared to the grafted rootstock. I can't believe that all rose varieties would be better off on say Dr Huey rootstock (mostly used in SA) and suspect the practice has a lot more to do with commercial benefits than proven performance. And by the way I suspect that a great deal of the rootstocks budded in SA are infected with rose mosaic virus as this is clearly endemic in the rose bushes I see in suburban gardens as well as even on new rose bushes being trialled in the National Rose Trial Gardens. |

Congratulations on your surviving cuttings.
You are right when you say that a lot of roses can do as well if not better on their own roots than grafted ones.
Some of the weaker modern H.T.s haven't the stamina to make it on their own though.
Also some roses are very hard to strike from cuttings and therefore grafting is a better alternative.
Of course it is quicker and easier for growers to take buds from a variety and graft onto rootstock.
One cutting size cane would produce 4 or 5 buds for grafting
so it is more expedient to do that.Some american nurseries are now offering 'own root' so there is a demand.
Personally I haven't seen any sign of rose mosiac but then I am in Vic so that may be the difference.

| Great news that you have had such success. I love getting things to grow from cuttings and seeds. I haven't been as successful as you with rose cuttings though. I got Albertine to grow using cuttings from my mum's plant and Buff Beauty was successful too. But I tried quite a few others in spring and they all rotted. I think I was trying to be too kind. I put the cuttings in potting mix in pots and then built little hot houses around them using bamboo sticks and gladwrap. They started off looking OK but after a month, they were all black and dead as dodos! Next year I will forget the hot house idea and use your approach. |

| In a shade house, in pots ,in creek sand and no hormone powder or no sliting down the sides, cuttings taken in Autumn and Winter,( watered every day hopefully !) worked for me. I got two big shade houses of cuttings to grow. |
