Fertilize your houseplants with a water-soluble fertilizer and remember to water them. Be sure not to overwater, as that can lead to plant diseases.
Start preparing your garden soil for spring planting. You can also prepare new soil for flower, rose, or shrub beds. Mix in organic material to give plants a healthy start.
Control the weeds in your garden while they are young and tender, or before they sprout. Remove weeds before they seed, so you can avoid them in your garden.
If there is a possibility that the temperature will drop to the 20s, you should protect your plants from frost damage.
Test your lawn and garden soil for its pH levels. If your soil is too acidic, you have time to fix it before the growing season arrives.
