Organic Rose Growing

yellow leaves on a new rose

19 years ago

We planted a new bush last month (a supposedly hardy hybrid--sorry, but I don't remember the name). At the time some of the leaves were curling under, but I attributed it to water stress since the weather had been dry. The curling leaves are still there and now about 20% of them are yellow starting low on the canes and seemingly moving up. We are in the middle of our typical mild fall here on Long Island, so I don't think it's shutting down for the winter. In the interest of full disclosure, the bush is planted over our recently departed hamster, so there could be some air pockets in the hole. I sprinkled in some epsom salts when I did the digging.. What's going on and how should I treat it? I would prefer not to dig the rose up, owing to the aforementioned hamster. Would a banana or coffee grounds help? Fish Emulsion?

Curling leaves could be a virus (uncommon) or a nutrient deficiency. The defoliation is from blackspot disease, if there are black spots. "Hardy" means cold-tolerant, not anything else.

If your rose survives the winter, next year give it a complete fertilizer such as Rose Tone every two months and water thoroughly once a week. You may need to do something to prevent blackspot, or get a more resistant variety.

Could be transplant shock. How much are you watering (probably not needed much this past Friday/Saturday, but...)?

This is the second time today that I've sent someone to explore Baldo Villegas' web site. Horror, Baldo Villegas is an entomologist employed by the State of California. He's also a very, very knowledgeable rosarian. We are very lucky to have Baldo. Go to: http://www.sactorose.org/rosebug/index.htm Check out ABIOTIC diseases of roses, and scroll down until you find CHLOROSIS. That's what your iron deficiency would look like. If that's not what you were seeing -- Iron wasn't the right answer. I believe I would cut (or snap) off the bud. Keep the plant from drying out, and see what happens. Jeri

New Rose of Sharon, leaves look sad/yellow/falling off...
Q

Aaron, Rose of Sharon will complain for a few weeks when you transplant them at all. That's just what they do. They will almost always bounce back after 2 weeks and start looking better. Water your shrubs generously after transplanting for at least a week. They need it, you are moving them in the heat and they need the extra moisture to get themselves situated in their new spot. Remember, they are not established for 3 years after you uproot them and move them around. So make sure for the next 3 eyars you keep and eye on the watering situation. Mulch is your friend.

black tips on new mini leaves, yellowing leaves and 'white sticky
Q

Annamaria- relax and enjoy yourself. The blacktip on leaves is normal and just pop them off. Soon new ones will grow fine. Yellow leaves are usually just done and being replaced with new ones and the white sticky stuff is just some latex leaking out. Remember, there is no place for mother hens in the plumeria world. They tend to over kill every thing and just cause problems. As long as leaves are growing everything is on the right path. Find your zen moment and leave the plant to grow. Do get an inexpensive water meter from a nursery so you know that your pot is still moist and water when it approches dry. The rest is just relax and wait. Bill

Yellow leaves on new roses?

Probably just a little shock from the change in growing conditions from the nursery to your home. Get it planted and give it some time to settle in. Keep it watered but hold off on fertilizing until it starts some new growth.

The yellow leaves are returning to normal though they still curl downward. The variety is something called "knockout" which the salesperson said was resitant to blackspot. We've had many inches of water in the last month (like everyone on the east coast) and the area is on a sprinkler. I've also added some coffee grounds. Hopefully it was just a transitional problem.

Knock Out is very resistant to black spot, but it is not immune. Glad to hear that it's coming back. It's pretty much an easy care rose, but buying it this late in the season says that it probably was a bit stressed anyway. Should be fine soon, but don't fertilize with anything until next spring.
