    Hi, I recently repotted my grape vines to a larger pot. These are vines I took as babies with their roots found in my area last year while keeping their dirt on the roots and bringing some dirt home not to shock them.

    They were great last year, but I brought them in for the winter and continued watering even after all foliage died away leaving what resembled dead twigs.

    This January, these twigs started sprouting all over the place (from the twigs, sending some up from under the soil, everywhere), and they were thriving!

    I waited for them to get a little more growth, and then decided to repot in a bigger pot (they looked like they'd need it badly). I did my best to take as much of them up with their current soil, and successfully did bring most up with their old soil sticking to their roots. Maybe four broke away (but I don't think any root damage occurred, or it was minimal if any).

    I proceeded to put some new soil over them, and near the top the soil is mixed with wooden chunks (like you'd find in the wild).

    I also put in a netty structure I made for it to grow onto. It was doing fine the first while. But I think I overwatered it once (giving enough water to make the soil damp from top to bottom) and suddenly I noticed the decline start.

    They began wilting away (the edges began turning a silvery or white-grey color rather than brown like when they dry), and I just let the soil FULLY dry out before watering again.

    It seemed to get better (or stop silvering), but I haven't seen much growth from it which is very odd for a grape vine. Further, many leaves actually fully dried into that silvery color and died, so I ended up cutting those leaves away leaving bare green stems. However, while my longest vines leaves died away near to the tip, it is one of the new growths that I have attached, and that part looks very nice. But I ended up cutting away a lot of the tip of the vine because I'd rather it put its energy into its new growth.

    Can you help by explaining what this silvering-graying of its leaves issue is? What can I do to help my vine survive and thrive? Is it going to survive?

    Also I just noticed (as shown in my photo attachment) that there is a white powder-like substance on most of the twigs, can this be what's hurting my vines? What should I do about it?

    I also found a little wild mushroom had began to grow in the soil (but started dying away, I was unable to get a photo of it because its cap was too mushy to be able to see it is a mushroom) and I did not plant it there! Is this like a weed? Should I be concerned? If so, what should I do about it?

    I live in Toronto Canada, and just put my vines out onto the balcony again as the temps were above freezing level (now the day temperature is 10C or 50F and night is 5C or 40F; Thursday it will be 22C or 70F in the day and 13C or 55F at night) to give them their natural environment. It is west-facing.

    Also, should I be fertilizing? If so, can I use my liquid 14-7-7 or my pink powder/salt 19-31-17 fertilizers at weaker/stronger strengths, or combined to make the right amount? Or should I get a new one? Or, do I skip that altogether and just water it?

    Thank you so much!
