Large hardy gesneriads - to split or not?
« on: March 15, 2017, 08:04:25 PM »
I have just inherited these 2 huge Ramondas, which I have never grown before. Would I be best to divide and repot, and if so when, or keep in the same pot and feed

to me it looks to be a Haberlea and not a Ramonda .I find Haberlea easier to grow than R.amondas

I think you may be correct Otto - but how do I treat such big plants?

I'd try tidying up the old dead leaves first, to see how the plants look then. If they are still a bit too scruffy, then be brave and split them up. Then water well and keep out of any late frosts to recover.
And yes, Haberleas!

I'm probably the World's worst person to ask that question Lawrence. I've had an Haberlea for about eight years now and it has flowered once in all that time. It was around four years ago after a cold(ish) Winter and hasn't looked like flowering since. I used to have it in a planting pocket between a wall and a set of steps but thouight I should it give it a change and I now have it in an ericaceous  bed with Rhododendrons and Saxifraga fortunei cultivars. It hasn't died but I don't know if it is appreciating the change!

If it's any consolation mine looks scruffy as well-see picture below. You might have a search on the Forum, there is quite a lot about Haberlea.

This Haberlea ferdinandi-coburgi thrives on neglect, it is also watered with our limey local water
when the rain water butts are empty.  Originally potted in peat(two dogs & a man don't look now)
it has been in this container for at least 15 years.

Wow Mike, that's really flowering. Yesterday I was surprised to see three flowers (not yet fully opened) on my plant and was pleased with them. I'd have been ecstatic if it had flowered like yours. I shall celebrate by giving it a sulphate of potash birthday cake!

I have only just found this topic.  Lawrence, if you don't have the courage to split the plant, you could remove one or two side crowns and grow them on independently without running the risk of harming the main plant.  If you separate the side crowns by cutting downwards with a sharp knife, they will most likely come away with some root attached, giving you a head start in getting them established.  To aid this, I would put the newly potted side crowns into a propagator to help reduce transpiration loss.  A little warmth would not go amiss either.  Now would be a good time to do it.
