Check out Martha’s to-do’s before transitioning your houseplants back indoors.
Putting your garden to bed each fall marks the end of the growing season and presents a wonderful opportunity to prepare your houseplants that have been outside to come back inside for the winter. It’s the perfect time to care for them before they make the transition indoors.
Give your plants a good cleaning. Dust and oils block sunlight, so clean plant leaves a week or two before bringing them inside. Spray succulents and cacti with compressed air or dust with a soft brush (water will cause leaf rot). For other plants, wipe smooth leaves with a damp bar towel or rag and lightly mist others. To clean several plants at once, set them in the shower under a fine, tepid spray. Then blot excess moisture.
Check them all over for signs of infestation. A convenient time is while watering. Brush leaves with a cotton swab dipped in alcohol to get rid of any insects. Once inside, regular cleaning will also help—you can add a few drops of an all-natural product such as neem oil to water.
If you notice roots peeking through the pot’s holes, soil drying out too quickly, or that the leaves and stems have stopped growing, the plant may be pot-bound and needs a larger container. When repotting, look for a container just slightly larger than the existing once.
Even if a houseplant doesn’t need repotting, you should still replenish its soil once a year. Use a fork to remove the top 2 to 4 inches, taking care not to harm the roots. Replace with fresh potting soil. A distressed plant might express it in a number of ways: Look for leaves turning pale, or frequent wilting. Miracle-Gro Organic™ Indoor Potting Mix is a good all-purpose choice.
Rotate plants a quarter turn every other week (or when it is leaning toward the light) for even growth. Experiment with watering and sun until you find the right fit. If your houseplant just doesn’t seem happy, try starting all over again with a healthy cutting.
Most houseplants need fertilizing from March through September. Fertilize both leafy and flowering plants before bringing them indoors and then once every two weeks for plants that flower during the winter, including after blooming. Remember, always dampen the soil before feeding so the nutrients go where needed. You can mix a liquid fertilizer into your watering can for easy application. Try Miracle-Gro Organic™ Plant Food for an organic option.
During the cold season, try not to disturb plants by relocating them. Ease up on watering and fertilizing, too. You can resume your regular routine once daylight hours extend and growth resurges.
MARTHA’S TIP - Give Plants a Lift
Sometimes small houseplants get lost among larger ones. Elevating smaller plants increases their visibility. And placing your pots at different levels will add a new dimension to the display. Simply turn a few small flowerpots upside down, and stack plants in pots of the same size on top. Intermingle these plants with larger ones. Use pots of the same material—terracotta, for example—to create a uniform look. Be sure to place plants on a waterproof tray or drain before setting them in the desired location, so water leakage won’t damage your surfaces.
