Gardeners' Notes:


On May 31, 2013, NorthSC from North, SC (Zone 8a) wrote:

Planted it as a 10 inch plant in a large pot with excellent soil and kept in a sunroom by the window and it started yellowing on the window side, so I moved it outside in the morning sun but a shade in the afternoon. It keeps on yellowing and some leaves burned light brown now.

June 30, 2013 update: the plant is still slowly declining and not growing at all. The ends of the branches are now bare. The seller advised to water it less and that's what I did. Also the soil is a really good mix that I mix myself from several ingredients that all plants love. Still no improvement.

Mid July update: the plant showed signs of growth after I stopped watering it and giving it just a cupful of ice cubes. It is protected from rain in a rain shelter.
