The cucumber vine itself isn't doing too well; leaves are dying off although strong tendrils remain. I've decided to just watch and wait. Maybe this is just a stage of growth or the vine throwing out one fruit in its last gasp. This cucumber plant has put me through too much. I've decided to remain detached -- give the plant what it seems to need but not get emotionally involved in its fate.
My calladiums seem to be dying out so I'm off to the nursery to get another lot. This time I will ask for growing tips and see what I can learn on the Internet instead of planting them and hoping for the best with just routine feeding and watering.
