I went out this morning just now, it is just light, with my magnifying glass, turned over a lot of leaves on many bushes, and there are some with lesser damage on the other side. Here is what I observed. No evidence of tiny wormlike or sluglike creatures, doesn't mean they aren't somewhere. A line under a leaf section of what looks to me like some insect eggs hanging from tiny webs, all exactly the same length, a whole row of those, only that one area of that so far, can't estimate the size because it was under the magnifying glass. Then I saw one tiny grasshopper, maybe a leafhopper. My daughter is supposed to bring some baby hawks over this am en route to the raptor center, so I'll ask her to take a look, too. That was the first thing she said last night. Aphids. So it appears I have multiple problems, and I'm not ruling out rose slugs. Oh do I hate to spray with all the bee problems and other beneficial critters, will definitely not use that Bayer stuff you put on the ground that is absorbed by the plant because I googled a post that said it drives the earthworms away, but I guess I'm going to have to decide on something. I never sprayed before other than that ortho powder and hoped I'd never have to, don't even have a sprayer, don't have a clue how to use one. I had aphids on my nasturtiums years ago and despite that ortho nasty powder I whooshed out of the squeeze container on them, every plant died, and I never wanted to grow them again.

You have a jade, aka, crassula ovata. It is in desparate need of light. Was this where it was when you moved in? If so, do you have a balcony on which you could slowly acclamate it when the outside temps are above 55 or so consistently. If you just moved it to this spot and it is better-lit than where it was, these could be sunburn marks. Typically sunburn marks are more uniform in shape, though. It should have about 1/5 the amount of space it has between the leaves. It almost looks like it is supposed to be a Crosby's Compact which should have all the leaves very close together with proper lighting. Jade grows spindly when it isn't getting enough light. I would take it out of the plastic pot and repot it in a clay pot. Buy one that is shorter. THey are sold as azalea pots. Your soil should be very free draining. When I mix mine, I use one part pine bark fines or soil conditioner, one part grit (decomposing granite), one part high fired clay granules (turface, aquatic soil), and one part small pea gravel. When you water it, water should run almost right through it. If you use peat based soils, they will compact and stay too wet, thus strangling the plant due to lack of oxygen. Even the soils that say they are for Cacti and Succulents are too peaty. You could also try coir inplace of the pine bark fines or in addition to them in place of peat. Almost anything you would use for a bonsai would be okay for a jade since they are very free draining. They don't need a lot of fertilizer. Use something low in nitrogen. I use Schultz Cactus Fertilizer mixed for every watering, but I only give it to them every other watering during their growing season. It is warm where I live until Oct or Nov, which is usually when I stop feeding and slow down watering to once a month until it warms up again in spring. We were warming up in March and then had a frigid spell over Easter holiday. I've gone back and forth with my plants, but having a mild spring has been nice for a change. I hope this helps, and don't hesitate to ask more questions. Do searches on this forum about Jades, and you'll get more than you ever wanted to know about jades. They are, without a doubt, my favorite. I have about 10 different plants, 10 starts from cuttings and two that are bonsaied.

there is a rose forum.. if you fail to get the answer here .... i doubt they died from black spot.....mildews are a function of hot humid nights... when the plant goes into darkness with water on its leaves .... when its ma natures fault ... there isn't much you can do .. except attempt prevention ... there are organic preventions.. i am sure someone will chime in ... i think its just baking soda .... increasing air movement.. and making sure you don't get water on the leaves late in the evening [from a sprinkler] ... all that said... if you are new to gardening... let me tell you this... you will not be considered a REAL gardener.. until you have killed each plant THREE times ... you are going to have to come to grips with the fact that stuff happens.. plants die.. and the garden evolves .... consider such losses to be part of the circle of life.. and a new opportunity to plant something else ... if the canes are still green.. there is a chance the roses might come back .... maybe not ... good luck ken PS: start getting pix of all your plants... so you can start getting ID's ... so that you can start learning about your garden .... something you can do all winter... so you can feel more at ease in the garden ....

We may be able to save you some dollars. Show us pictures of the suspect leaves. You need a test lab that deals with plants. Contact your county's Extension Service office to obtain that sort of info. You can locate your county's office with this interactive map: http://npic.orst.edu/pest/countyext.htm By the way, if you are allergic to an airborne fungus on your tree, it's likely that removing the tree won't help. I assume your allergy tests were done by a medical specialist. If so, that person should have suggestions for you. Perhaps a series of desensitization injections may help. Also, there's the issue of seasonal pollen in the air. Further, an individual's allergies are often multiple, not to just one thing.
