Problem with rare Scadoxus tubers

Hi Benoit,

Re: Scadoxus pole-evansii and S. pseudocaulus bulbs.

As with many amaryllids that produce an extensive fleshy perennial root
system, Scadoxus bulbs may skip a year while they grow new roots after being
disturbed. Watering in the interim can be tricky. I just water once the
medium is nearly dry. Unlike Haemanthus species from Namaqualand, Scadoxus
are more tolerant of (and perhaps even need some) water when they are
dormant. Be sure that your potting medium is well-drained and that the pot
you have chosen is not too big. A bulb with few or no roots will rot more
easily in a pot that allows too much of the medium to go unused by its
current root mass size. Also keeping your bulbs moderately warm, such as on
a heating mat can be another safety measure when helping things go through a
transition period following major disturbances.

Best wishes!

Jacob
