Well now you know. Vinegar is not good for live plants, but it is very good at killing live plants. Since you really have no other option, I am with gardenper. Try to salvage them by flushing them with clean water, a lot of water. Do a foliage flush and a root flush. Throw your vinegar solution away! After flushing them, trim any branches/leaves that are completely dead/obviously on their way out, and then I'd give them a batch of fertilizer. I don't typically spout the use of miracle grow, but go for it!! There is a possibility that they have enough energy stored up to make it leafless for a couple weeks. The miracle grow may give it enough nitrogen to start immediate leaf growth. I had a hibiscus this year that got a shot from the neighbors herbicide and I had to do this exact same method. It has rebounded amazingly! There is a chance the fert will finish her off, but you really don't have any options. You need new healthy growth asap!

EricSmith; Please refrain from slandering GH if you've never used it. Many people on here, including myself, have used it and used it successfully without any recurring similar issue. the nutrient is not the problem. I will ask again, do you work for Advanced nutrients? It seems every post you make either pushes AN, or tries to diminish some other brand of fertilizer. so to put it like the late Jerry Garcia used to: "Please don't dominate the rap jack, if you've got nothing new to say."

This looks similar to what I am seeing on my tomato plants. (Here is my post about it.) We did have couple of cold nights here in MA. So may be it was cold winds. My plants are outside for last three weeks though. So they are hardened off ..

Hi rgreen, I think that's a good idea to raise a pot for small plants and it certainly could be utilized on the balcony. But for tomatoes I would not be too keen on it. As was brought up by digdirt, the saucer is performing two functions, specifically that to catch overflow, as well as to provide a reservoir similar to an SWC ("self-watering") does. If you go to the extreme of ncrealestateguy, in this case, having a saucer without being a saucer, that would be a great solution for some plants; I don't use saucers for my containers myself ... but it Sun showers on them every day too in my coastal, humid climate. Here are my two concerns. House plants have very low nutritional requirements. The tomato is on the other end of the spectrum and consumes a great deal of water and nutrients. The pot being used by Marion simply does not have the holding capacity for its demands of up to a half gallon per day in summertime, and by the time it is into fruit production it's more critical. Marion needs the reservoir for this water buffering, and your solution will break the wicking ability and just be a drain catch. That will cause the soil to dehydrate without very frequent irrigation which can easily slip her mind and result in a stressed wilted plant. Secondly, and it is not clear, you may be suggesting she dispose of the overflow. This is not necessary, either way, it could be done if you want. But keep in mind the fertilizer rates we suggest somewhat have built in the building up of fertilizer and if the pot sits too high on risers the fertilizer will need to be increased and there likely will be more fertilizer waste. For an African Violet you won't notice, but for a tomato it would hit the wallet. Perhaps experimenting with the additional variables and a working system could be designed. That system would require more attention than simply choosing a wider saucer. It would completely or partially remove the water from soil contact which has the above drawbacks (and potential benefit of avoiding a rot situation) but demand more care and attention. digdirt's suggestion to get more Sun when possible up there in Canada will probably result in healthier, more productive and tastier tomatoes. The more Sun on this pot, water not only drains, but the more evaporating out of the sides, so soil/growing medium dehydrates even more quickly. PC
