Question
Hi Will,

I have a question regarding my Goldfish plant (Nematanthus
nervosus). I live in Englewood, NJ, and the plant is on my bright,
sunny porch, gets lots of light, and is doing very well. In fact, it
is growing right now (in January) so much that I am wondering if
I need to prune it. It looks GREAT, but the stalks are starting to
get so long and heavy that they are bending out and over the
pot (although still ultimately pointing up toward the light). New
green growth is shooting out of almost every stalk. I don't think
it needs repotting yet, but I don't want it to get too heavy for
itself. Is it OK to prune new growth, and also is it OK to prune in
winter? If so, how much do I cut off each stalk?

Thanks for any advise!

Sincerely,

Stephanie Seymour


Answer
Hi Stephanie,

Unfortunately, your goldfish plant needs a rest period in the colder months if it is to flower in the warmer months. In general, from November through March it is best to stop fertilizing, keep temps on the cool side, and water just enough to keep the plant from wilting, allowing the soil to become quite dry. Growth will be minimal and there will be no flowers during this rest period.

In April, resume normal watering, keeping the soil moist, and fertilize monthly at half strength. It must be in a sunny window (south or west) to thrive. Expect flowers from July-September. Prune long stems back to within a few inches of the soil to keep the plant full and bushy.

Yours is a bit out of cycle at this point. I suggest that you prune it way back now, as painful as that may be, then keep it dry and cool until April or May. Hopefully that will be sufficient to set buds next summer.

Please let me know if any of this is unclear or if you have any additional questions.
