  • On apple and mountain ash trees, prune away branches killed by fire blight to prevent further spread of the disease; also prune black knots off of cherries. Make cuts 1 foot below the diseased area. Disinfect pruners with a 10 percent bleach solution between cuts.
  • Start pepper and eggplant seeds indoors under lights.
  • Start seeds of zinnias, salvia, petunias, and nicotiana indoors under lights.
  • Pot up seedlings started last month and potbound houseplants.
  • Don't rush to remove mulch from perennials: The sun could heat the soil and stimulate new growth, which the hard freezes still to come could damage.
