Kelly,

A couple of thoughts:

I do not grow this hoya but it sounds happy as is and perhaps if it is potbound it will be inclined to bloom for you. Also - am wondering why you would change from clay to plastic as it seems to grow well in clay. Is this possibly an effort to reduce the amount of water it requires? I am a fan of 'if it ain't broke, don't fix it' and it seems like you are growing Mathilde well. Regardless, growth may slow during the winter, and consequently, it may require less water. If it were mine, I would wait until next Spring and pot it up to clay.

I agree with Lisa on this. It seems to like where it's at. Growth usually slows down in the winter so, if anything, I would at least wait until spring. Hoya like to be potbound, so putting it into a larger pot will give it a message to make more roots, and less chance of bloom. Just adding my thoughts.

Hoya Mathilde likes the cool weather seasons just like its parent Hoya serpens. I don't think that potting up now would be a bad idea if you find that the plant is drying out far too fast in clay. Then again I almost never pot in clay and every time I have repotted a Hoya from clay it has pouted because the roots inevitably get damaged.

Thanks gennykins, ima digger and Mike :)

You all brought up some good points. The plant does dry out quickly, but the days will be getting cooler soon and I won't have this problem for much longer, you're right. That sucker did take off this summer, and possibly it likes being potbound. All of the long vines have peduncles on them, but we'll see if any actually set flowers! I think what made me consider going to plastic was seeing all of this new growth and tiny leaves & peduncles and feeling a bit worried about forgetting to water it frequently. I lose a lot of new leaves that way. She's staying put anyway. Thanks again for the input!
