Keeping Holiday Plants Healthy


As the Holidays approach, many of us will use a plant or two (or more) to decorate our homes. With a little extra attention, their beauty can last well past the Holidays.

  • When selecting plants for purchase, pay attention to where the plants are displayed in the store. Warm or cold drafts can harm many holiday plants—it's not unusual to find displays of Holiday plants displayed near entrances where they regularly get blasted with either cold drafts from outside, warm drafts from the heating system, or sometimes all of the above.
  • Select plants still in bud and just beginning to bloom if at all possible. This will maximize the length of time to enjoy the blooms at home—more bloom for your buck so to speak.
  • Select plants that look to be in good health. It's very likely that a plant that looks sickly in the store is not going to improve once you get it home.
  • Take the time to ask for extra coverings for your plants when purchasing so you can get them home safely. Some plants, such as poinsettia, will drop their leaves when exposed to even the briefest of cold temperatures.
  • After safely bringing your plant into your home, it is important to remove any protective wrappings that may be on the plant. Clear plastic sleeves, even if they are open on top will hold too much moisture and the plant will likely deteriorate rapidly without adequate air circulation.
  • Some Holiday plants may have decorative moss covering the soil. This decoration is attractive in the short term, but for long term health of the plant, it is best to remove decorative moss. It tends to hold too much moisture which may contribute to root or crown rot of the plant.
  • Holiday plants are often sold in decorative plastic or foil sleeves, or decorative pots without drainage holes. This makes it very easy to overwater. It is a good idea to remove these decorative items when watering, which will allow excess water to flow freely from the pot. If plastic or foil sleeves cover up the plant, fold them back or trim them to allow for good air circulation around the plant. Check that water is not standing in any decorative sleeves or pots after watering. Standing water will promote root rot.
  • Overwatering is one of the top causes of not only Holiday plant death, but houseplant death in general, especially in the winter months. As a rule of thumb allow soil to dry partially before watering.
  • How can you tell if a plant is dry? A dry pot will feel lighter than the same pot after watering (this takes some practice to recognize), and when you insert your index finger up to the first knuckle, the soil will feel dry and not cling to your finger.
  • Another unpleasant side effect from overwatering besides root and crown rot is fungus gnats. Eggs of these pests may be present in the plant's soil and they develop and hatch when the soil is kept overly wet for extended periods. The adult gnats are annoying, but the larvae will damage the plant by eating its roots. There are some expensive treatments on the market for fungus gnats, but the most economical solution is to let the soil dry out, and in extreme cases repot the plant after removing as much of the infected soil as possible.
  • Though overwatering is tough on plants, so is underwatering. Repeatedly allowing a plant to dry to the point of wilting may damage the plant. On a blooming plant, repeated cycles of wilting will shorten the life of blooms present and may cause buds to drop.
  • Although many holiday plants are used to decorate our homes during the holiday season, they still need to be placed in an appropriate location at least most of the time. It's fine to use a holiday plant as a centerpiece or accent in your home during a party, but after the festivities return the plant to a location with bright indirect light and a comfortable room temperature (68-72ºF). Blooming plants may hold their blooms longer in cooler rooms.
  • No matter where you place your plant, party or not, avoid cold or warm drafts at all costs. Drafts will often cause flower or leaf drop. In the case of the popular poinsettia, the plant reacts very quickly. I have seen poinsettias lose leaves within minutes of experiencing a cold draft of a few seconds.
  • It may be tempting to fertilize your holiday plants, but hold off until Spring when growth conditions are typically more ideal. For the time being, remove blooms as they fade to promote development of new flowers. Also remove any dead leaves or other debris.
  • Above all, enjoy your Holiday plant! For more information on care of specific Holiday plants, contact me at U of I Extension in Macon County at (217) 877-6042 or jaschult@illiois.edu. Happy Holidays!
