With your home’s heating system now running full time, your house plants will need more water to compensate for much lower indoor humidity. Check them frequently for dry soil. They will also appreciate regular mistings.
If you plan to put lights on outdoor trees or shrubs, do it now. Why? Because the branches become more prone to breaking as the weather turns colder. After the holidays, leave the lights in place until you have a warm day when you won’t risk damaging branches when you remove the strands.
When you cut greens for indoor or outdoor displays, remember those basic rules for pruning so you do not accidentally transform a handsome tree or shrub into a landscape liability. If you like bright, berry accents among your greens, use artificial ones instead of taking berries from the birds.
Leaves and other clean foliage should go into your composter or compost heap. Leaves run over by the lawnmower are a great source of nutrients for new plantings and existing lawns. Spread mulched leaves over old garden beds. The leaves’ nutrients will move toward the roots from the freezing and thawing action of the soil.
