problem with rose leaves

16 years ago

These are my first tea roses and their leaves appear to have something wrong with them. Does anyone know what I need to do for them?

    Sometimes new leaves are curled if there is cooler weather when they are forming. I don't think it's anything to worry about.

    Yea, I just went through something similar on a rose. Mine got really bad so I shovel pruned it this morning. I think maybe something happened to the root system? Or it was some type of disease? Who knows? lol

    Your second pic looks normal. Some roses the new growth is red and does curl under certain conditions.

    Not sure about your first pic as it is somewhat similar to what I had going on. And I have no idea what caused it.
    Where did you buy those roses?

    Rose in your first pic: Was it like that when you bought it or did it start doing that after you planted it?

    Jim's question above is important, and how long ago did you plant it?.

    The rose in the pot is fine. The one in the ground might be showing a severe deficiency or excess of some nutrient. What if anything did you put in the hole?

    Generally in planting a rose you should dig 3' wide, remove the grass, and mulch heavily.

    I bought it at a local nursery. It was fine when I bought it. I have a couple of others that I bought several weeks before this one and they are ok. I've had them a couple of months.

    The hole was smaller than that and I put potting soil in the hole with it. I fertilized them several weeks ago. The one in the pot didn't get fertilized.

    This week I bought some of the fabric (I forget what it's called) that I'll put around the base and them put mulch on top of it. I plan to do that tomorrow.

    You have may have over fertilized, esp since you used potting soil, which may be part of the problem. Potting soil is for house houseplants. I would dig it up and use a mix of half compost or manure and half dirt (from the hole or some other part of your yard). Do Not put weed barrier fabric down. Do not put mulch closer than three inches to the canes. Do not put more than 2" of mulch. Deep water once a week (or twice if it is over 90). Deep watering is either a very slow drip for about a half hour or build a three inch deep well around the rose, fill it and let it soak in. Do not fertilize for two months.

    In the first pic it looks like when the new leaves were growing out, aphids were eating them and they grew deformed and with holes in them.
    Second pic looks like you may not have good drainage, what kind of pot is that? Is it ceramic or red clay? They are really not good pots for growing roses in because of there not enough holes in them.

    txcactus,
    The wrinkling in the 1st pic looks like either slight frost damage or cool weather leaf formation, as half of my 200 roses were displaying similar leaves even before they were fertilized this year and we had plenty of cool and frosty days this year after spring growth began.

    I also think the 2nd pic could be a drainage problem... and with the amount of pearlite I see in the pot, (if it is a drainage issue), the only problem could be that there aren't enough holes in the bottom of the pot or none at all.

    Do you remember the name of the rose?

    Name of the grower? ie., STAR, WEEKS, J&P, BAILY, CONRAD PYLE....?

    Was the rose own root or grafted.

    Sorry to ask so many questions txcactus, but it's kind of important to follow unfamiliar anomalies in plants these days... it may help to halt an outbreak of something destructive to the rose industry. :)

    Jim and Michael,
    I see the same purplish/maroonish discoloration in the mature leaves that were present in Jim's bush that he posted pics of a few days ago.

    Is that the bush you SP'd Jim?

    Do you guys think this is a new ailment of some sort?

    The coloration doesn't bother me in the least.

    The leaves curling and wrinkling? There is some discussion as to whether that is caused by a virus -- but that is by no means certain.
    I don't see a real problem here, at this point.

    I second that the first picture just shows aphids damage. When aphids are heavy in a leaf infant stage, that is what you get. It could happened before you bought your roses, but these leaves are opening now and you see the result.
    Michael with all due respect, I never dig 3' wholes. I would have no roses if I had to do this :) I dig a whole sufficient to hold roots. In my soil (very heavy red clay)roses don't mind this. I understand that it is all soil specific.

    Hi All, thanks for the help and suggestions! The rose in the pot is a Tiffany and is on it's own rootstock. It was suggested by the grower (Rogue Roses) that it be grown in a pot for a couple of months after I received it. The pot is plastic. It's now ready to be planted in the ground.

    It could be aphids but I watch my plants pretty carefully for critters and haven't noticed any. That doesn't mean they aren't there though.

    We did have a cold snap awhile back. I wrapped them in frost cloth but the tender new growth could have been damaged.

    Ditto on not using landscape fabric. Maintain a mulch 3" deep. I would go ahead and dig the planting site 3' wide and incorporate 2-3" of compost or composted manure. The soil under lawns is usually compacted.
