Put cut flowers around the house as a progenitor to spring.
If perennials have been heaved out of the ground by frost, press them back down.
Remove heavy snow from evergreens.
Inspect trees to see if they could benefit from pruning. It is easier to spot broken or diseased branches without leaves.
Now is the time to plan garden renovations, and place catalog orders.
Make note of plants that have winter interest. Find out what they are and plan to add them to your garden when good weather returns.
Sharpen tools, and organize while you’re at it.
Prune grape vines now. In warmer weather they will bleed.
Start vegetable seeds this month or next in clear topped leftover take-home trays.
Force some spring blooming twigs (fruit trees, forsythia, quince, dogwood, pussy willow) for indoor color. Bring them inside and allow them to sit in a large water filled vase.
Keep bird feeders full.
Wipe the leaves of indoor plants.
