Pieris Japonica 'Little Heath'
Anyone have experience with this little shrub ? I've got two in six inch pots, but I garden on a tenth floor balcony, more or less southwest exposure. Native elms, dwarf lilac, cotoneaster and japanese quince have survived multiple winters out on this balcony, in 10-20 inch planters, without any special protection. I have read that pieris is susceptible to winds, it's super windy on this balcony.. would they be OK if I buried them in the potting soil bin, [ big garbage can I keep my potting soils in], or perhaps in a styrofoam cooler, surrounded with mulch ? I am unsure whether, as evergreens, they need exposure to light during the winter or not. Any help greatly appreciated.
