We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
It needs to be now lower than about 60 degrees at night. 45 is much too cold. I don't know anything about your area, but I don't give as much credence to the air temp as the soil temp. My soils don't warm up soon enough, so I start indoors in containers.
Caladiums planted about a month ago are starting to sprout and grow. Still awaiting an elephant ear to sprout. It has been so warm that I take the kids outside for a romp :) during the day and then put them to bed in my kitchen at night. I can't wait for warm nights!
So are the bulbs wasted ? Do they rot in the ground ? Do I just wait it out for warmer weather? It is mostly shaded there also. When I planted them it was in the 60's at night but it has gotten cooler since then. That's Arkansas weather for you.
