Thankyou Tasv and Bemo for your thoughts and imformation. It is so good to be able to come here and get help with what I need to learn. | ||

The manner Tasv mentioned is also my favorite one. It's also described by Peter Beales: http://www.classicroses.co.uk/articles/hybridising/breeding_roses_hybridising.ht ml It's also a good general abstract of rose breeding. PB recommended about 16 weeks of ripening time. I believe it also depends on the weather condition you have. Gerd Krüssmann wrote in his great work - the complete book of roses- :“ The hips are ripe when the colour turns red“ Last yearI have harvested some green hips from Monlight, Sympathy and Lichtkönigin Lucia. They had a minimum age of 16 weeks. I will report you if some seeds of it will germinate The perlite I use (80 l bag for about 12€) is normally used for building insulation. It works well. I also mix up my soil-mixtures with it. With sand I've no good expierences, may be the graduation I used was to fine  regards Bemo | ||

Wait until Autumn Karen. That way you know they are ripe. It's a little hard to generalise about hip colour because I don't know what your seed parents are and different rose's hips ripen to different colours. Here's a quote from the RHA forum "Past articles in the RHA Newsletter have indicated that, regardless of the color of the hip, seeds on HTs are generally ready to germinate 14 weeks after pollination (and give the best germination if harvested at this time). " the whole thread is here: http://rosehybridizers.org/forum/message.php?topid=6254#6261 When the only tool you own is a hammer, every problem starts looking like a nail... | ||

Thanks Tasv for your quick respose, I will get the perlite as soon as I can. It looks like I might be a rose breeder of open pollinated seeds soon after all. And I have some hips maturing that I fertilised with Fortune's Double Yellow's pollen. Will it take till Autumn before they will ripen, seeing I pollinated them fairly early in Spring ? That was very interesting about the largest collection of Teas, Chinas and Noisettes in the World to be started at David Ruston's rose garden. Very excitting. Though frustrating for you. Though I couldn't find a part at that link that told about budwood or cuttings for sale. I had that trouble when I had a look at that link before. I will ring them anyway and get them to send me a list of the roses they can take cuttings from. Bruce said he had got one. I am not real good at buding yet. I have had four graftings work for me so far. A great deal of failures, my rootstocks weren't old enough I think. I am trying cuttings under cut off bottles, seeing I have had one quick success recently of rooting a sport ( I think ), it was yellowish( I think. I should have took a photo of it ) of Mme Antoine Mari. | ||

Hi Karen, I've had best luck with moist perlite in zip-lock bags. I just moisten a handful of perlite, put it in the zip lock bag and mix the seeds through it. You have less worry about mould that way (though a bit of mould doesn't hurt the seeds... in fact it may be beneficial in breaking down the 'seed coat'). The zip lock ensures they don't dry out. Now... seeds go dormant and the longer they are dry the more effort will be requried to wake them up again. You will probably find that if they are still in teh fridge, if you add a little water they will start germinating after just a few weeks. I have heard of rose seeds up to 5 years old germinating so seeds from just last winter should still be ok. If you can't get perlite then sand will work just fine used in a similar manner. If you don't have any sand then the easiest thing of all is just to get some paper napkins or paper towel, moist it and wrap the seeds in this and pop them in the fridge and wait for germination to begin. I like the perlite because I just pour the contents of the ziplock bag out into a pot once they start to germinate, seeds and perlite mixed together, cover lightly with soil, and water it in. The perlite helps to get a more even distribution of seeds in the pot. I've been looking through HMF for which roses I want to buy for breeding this winter too but are you aware that Ruston's Roses is selling budwood NOW. If you can bud then you just drop them a line and ask for budwood or cuttings of a particular variety to be sent out and they will get back to you as to whether they have it in stock or not. I don't know the cost yet but Ann Ruston emailed me a few days ago to let me know that this is possible for hobbyists like us and I think this would be a good cheap way of doing it and help to satisfy the addiction while waiting for winter to come around again to buy bare root roses. They are at http://www.rustonsroses.com . I can't do it easily because they don't have certification to post to Tas. They do, however, have certification to post to WA and the rest of Australia. When the only tool you own is a hammer, every problem starts looking like a nail... | ||

I have been spending my computer time at Helpmefind roses, working out what roses I want to buy this year. It is such a fanstastic help to working out what roses should be the best to have. My question is about quite alot of rose seeds I put in the fridge back in winter. I had forgotten from years ago that you put spagneum with them to get them to germinate. Then somone here reminded me about it, but I haven't got around to getting some more spagneum after running out after sending it through the mail with my baby ownroots. If I do it now will they germinate after being dry in the fridge all this time, and grow alright if I keep them in the shade house and in winter in our hothouse ? Our vegetable garden has grown beautifully in the hothouse, only promblem is the slugs. The hot house roses are definitely better outside, no back mold or sticky stuff on them now. At present have lots of little roses on them. Hopefully in Autumn or next Spring they will have lots of lush growth, big blooms and long stems for cuting. |
