Re: first roses of the year

These are photographs of the inner part of my mini orange rose. A flower that hadn't yet fully opened accidentally got knocked so I pulled the petals off it to look what was inside a new rose. How would I find out if it was producing pollen or if its stigma was functional? It seems to have multiple ...

Re: How do you care for seedlings?

Two of my little seedlings, planted last October and germinated about March this year. Fingers crossed they survive.

Re: first roses of the year

Red mini rose yellow centres. These mini dark red roses don't seem to have any scent, other than a weedy sort of smell. Nice colour, and the flowers don't nod. Like all three mini rose varieties I have (white, red and orange), they flower constantly all summer and right up until about February when ...

Re: first roses of the year

Here are photographs of my other two mini roses. The white ones were the ones I was having trouble with "nodding" flowers, which seems to be sorting itself out now. They are quite big, maybe they weren't originally mini at all. I haven't had a look at the yellow centres yet. The red ones were needin...

Re: first roses of the year

I had a look at the flower of one of my mini roses, and struggled to make out stigmas from anthers in the middle yellow bit. I did notice that in the warm weather these orange roses do have a scent. I had noticed a nice scent a couple of weeks ago but thought it was coming from somebody else's garde...

Re: How do you care for seedlings?

Roseseek, thanks I had a look at your interesting blog. My terracotta pots are quite big. I do have other pots that are made of a sort of fibreglass, that my roses seem to like. I will try to think of making something with wood.

Re: How do you care for seedlings?

The two seedlings that suddenly withered and died are in terracotta pots, with two surviving seedlings in the same pots. The seedlings in plastic pots have survived. Of the terracotta pots, one is old and unglazed and one is new and glazed. Our weather has been quite warm for the past couple of week...

Re: first roses of the year

You might look at the pot plants at your supermarket or Big Box Store and look for varieties that have small foliage (so when normally grown it doesn't get large) and, of course, a beautiful flower with perhaps 20 to 30 petals, then peel away the petals of one flower that is almost open to see whet...

How do you care for seedlings?

I planted a lot of rose seeds last October, and they started to produce tiny seedlings about March. No stratification, I just cleaned the rose hips and planted the seeds outside in potting compost, watered and left over the winter. I now have maybe seven or eight little seedlings. I lost a lot throu...

Re: Rose flowers droop as soon as buds fully open, why?

I think there is a good chance that this will self-resolve after a while, especially if it only just started happening relatively recently. The second flower of this rose to fully open this year has opened perfectly, with no drooping/nodding. Last year this variety all drooped/nodded, and the first...

Re: Rose flowers droop as soon as buds fully open, why?

That will teach me to think those un-named miniature roses sold as houseplants would make a nice outdoor plant. They come with I think a six week guarantee. I will see what happens as the plant matures, but expect to be disappointed. I bought a proper named rose, Blue for You (Pejamblu) which has st...

Re: Rose flowers droop as soon as buds fully open, why?

I think there is a good chance that this will self-resolve after a while, especially if it only just started happening relatively recently. Sometimes greenhouse growers apply growth regulating hormones to produce more compact growth in plants like the ones you purchased. I don't know if that's the ...

Rose flowers droop as soon as buds fully open, why?

I have been searching for an answer and not found one, though I have found references online to this problem, I couldn't find any reasons or solutions. I have some miniature roses that came from a supermarket-bought miniature, which I split and have grown in bigger pots outdoors. When it was a minia...

Re: silver nanoparticles use in vitro culture

Karl, thanks for that information about Charcoal. I have some odd bits of activated charcoal lying around, I might give it a try.

Maybe as you say it is about heat and possibly oxygen, or its surface area, or some sort of catalyst.

Re: silver nanoparticles use in vitro culture

I did a rough controlled experiment, tried rooting some cuttings from a rose I grew from seed (though I suppose if I wait until autumn I might have some more seeds). I tried some cuttings in water with a bit of colloidal silver, and one cutting I put in water with a dissolved aspirin tablet. The cut...

Re: silver nanoparticles use in vitro culture

Does a bit of colloidal silver prevent rose cuttings in water from getting fungus?

Does anything else added to the water prevent fungus killing rose cuttings that you root in water?

Re: Petite Knock Out Rose - AVOID

Srdjan, thanks for that information about the EU. I don't understand what CRISPR's are? Are they GMO? Edit: I just tried looking up CRISPR, and I understand that it is slightly different from GMO in that they just re-arrange genes already in that plant as opposed to GMO which introduces alien genes....

Re: Germinating seeds

I wondered if rose seeds require a cold period followed by a warm period to germinate, which happens when you get a cold winter followed by spring. Needing a cold period would stop the seeds from germinating immediately in the late summer and autumn, as the seedlings wouldn't have enough time to gro...
