Perhaps I should have said "container", rather than "pot". Either word, your tree is growing on a NYC roof, and not in an actual meadow. That you are able to keep other, putatively more sensitive, trees thriving is great. As you may have gathered from the number of recent posts about cherry trees, weeping or otherwise, many people have difficulties with them. It may be that something damaged the bark, and sap wept out and solidified, and there is no disease involved. It is possible that your tree acquired a borer - does it look like the sap solidified from a small hole? It is possible that your tree does not have gummosis - all you can do at this point is wait and see. Keep an eye on it, and if there looks to be something else wrong, then post again. That the soil was sterile when you planted implies that if your tree has gummosis, then it came from the nursery - I don't know the incubation period well enough to say for sure. But, I am sure your trees are visited by birds and insects, so one of them could also have brought some disease in on feet, feathers or through droppings.

That is a great deal, but you couldn't run fast enough to give me an all gas stove. In my previous house I had a dual fuel Viking and I loved it. In the current house, I have an all-gas GE Cafe. I hate it. EVERYTHING burns in the oven unless I use the convection mode. I was going to get the GE Cafe in dual fuel, but a friend who has the all gas GE Cafe told me that the all gas worked fine and I didn't need to spend the extra money. I forgot to take into consideration that she does no baking and no from-scratch preparation. All she needs is something that will bake a pot pie! Although I had not one minute's problem out of my Viking, I understand they can be finicky. I would only buy the used one if I could adequately test it. If you can get the serial number off the Viking, I'll bet their customer service can tell you how old it is. They may also be able to tell you if it has had any service calls. Viking customer service is very nice and very helpful. (I said I had no trouble out of mine, but the granite installers beat it up pretty badly and I had to get a repairman to replace some parts.) [sigh] I wish I had a Viking again instead of the POS I have. Here is a link that might be useful: How to find Viking serial number

Post the request in the Kitchen forum - that's where the good suggestions come from. Let them know what the landlord is willing to let you do, and what the budget is.

Be careful, if they have not been making these for over a year, that means that the ones you buy have been stacked somewhere for that period of time and might be difficult to separate. Also just because no one makes a shingle with a particular name for the color does not mean someone isn't making the same color and using another name. Take a sample and check out all the places you can find that sell shingles. It is not likely that you are going to find a perfect match anyhow because of fading and weathering. Buy some that are just a bit darker and pretty soon they will match pretty close.
