Re: Yellowing of rose leaves.

Cement is mostly calcium silicate plus a little calcium sulfate so that concrete is most likely the same except for sand and gravel (I looked up Portland cement on-line). Magnesium sulfate has the oxidized form of sulfur, sulfate, so if you take away the magnesium it is sulfuric acid. The final pH ...

Re: Yellowing of rose leaves.

It sounds like your water might be the problem. You could use citric acid to acidify it prior to using it, if possible, or use rain water. There are pH testing strips that you can order on eBay...the more detailed the better from 4.0 to 9.0. It is fun to check your tap water's pH and then add citri...

Re: Yellowing of rose leaves.

I just bought and used a bit on my roses with yellowing leaves a product called Horticare Rose and Shrub Feed. I bought it from the Pound shop in the UK. I got it because it says it contains Iron, and also Manganese and Calcium, and it was extremely cheap, only one pound. It is dark brown and slight...

Re: Yellowing of rose leaves.

Thanks for this information. I am still searching online trying to decide, and I added some home-made compost to the soil of the roses that have yellowing leaves. I would have thought bought potting compost is coconut fibre, peat, or something similar, which should be acidic, but our tap water is al...

Yellowing of rose leaves.

Some of my roses have yellowing of their leaves in between the green veins. Only some of them, and I managed to cure some of them a few months ago after using some Bonsai Food that somebody gave me, which had chelated minerals like EDTA chelated Iron and a lot of other chelated minerals in it. I was...

Re: Are Roxburghii flowers supposed to look like this?

I think all of the flowers from those two packets of seeds that actually grew turned out to be Rosa Chinensis Angel Wings. They all have multiple tiny buds and tiny flowers, much more small and multiple than other roses. I probably planted the Roxburghii seeds somewhere where they were lost, acciden...

Re: Are Roxburghii flowers supposed to look like this?

Ah, that actually makes a lot more sense! The "Angel Wings" roses are not really Rosa chinensis as labeled, but rather, derived more clearly from R. multiflora with perhaps some R. chinensis influence that provides the repeat bloom. R. roxburghii does usually have very unusual hips (spiny, yellow, ...

Re: Are Roxburghii flowers supposed to look like this?

I grew two lots of bought seeds, one was Rosa Roxburghii and the other one was Rosa Chinensis Angel Wings. I am starting to wonder if I mixed them up by not labelling them properly and having to move pots around. I suppose the real test is when they form hips, as Rosa Roxburghii has very distinctive...

Re: Are Roxburghii flowers supposed to look like this?

I should have responded about the petaloid stamens (the structures you observe being between petals and stamens)--that is a common feature of many double flowers, since additional petals are generally caused by a mutation that converts them from stamens. Roses that are not completely double (which,...

Are Roxburghii flowers supposed to look like this?

These are some flowers that I grew from Roxburghii seeds. Are they supposed to have those bits that can't decide if the are petals or stamens?

Re: Yellow seedling

Julie, These are seedlings that germinated and were planted in March or April of this year....I can't remember exactly when they were planted. One important principle in rose breeding is that if a rose will be a repeat bloomer it generally blooms like this at a very young age, in it's first summer....

Re: Yellow seedling

How long does it take to get from seed to a small plant with flowers like that?

Did it flower in its first summer?

Re: How do you care for seedlings?

Today is very hot here, about 24 degrees Centigrade (75.2 Fahrenheit), and I checked to see how hot my plant pots are getting. My big glazed terracotta pots and my big fibreglass/clay pots seem ok under the canopy of leaves, the pots and their compost aren't getting hot at all, but they are in parti...

Re: first roses of the year-mini orange

Teh enter on that one is very "muddled". I see only about half a dozen definite stigmas. So it could be nearly or quite sterile as a mother. On teh otehr hand there are lots of anthers all round. If you just leave this cut rose on a sheet of waxed paper, or on a white plate, you should be able to s...

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.
