You might have heard that it’s not recommended to repot houseplants during the winter. However, while repotting plants in the winter is not ideal, there are certain circumstances where it may be necessary. Whether you’re worried about root problems or simply want to give your houseplants more space, here’s how to determine if your plants need repotting in the winter, along with tips on reducing stress for a recently repotted plant during the colder months.
Repotting Houseplants in Winter
Typically, winter is not the most suitable season for repotting. With shorter days and reduced light, plants naturally grow slower during this time, resulting in a lower demand for repotting. Additionally, many houseplants are semi-dormant in the winter, and repotting them at this time can lead to increased stress and the risk of overwatering. It is generally best to wait until spring when plants are growing faster and more likely to adjust to their new pots. However, if your houseplants are struggling due to stress, pests, or other issues, repotting them in winter is also acceptable.
Reasons to Repot in Winter
Repotting a houseplant in winter might be necessary if the plant is displaying signs of stress. Here are some indicators that winter repotting may be required:
1. Rootbound roots: Overgrown roots appearing above the soil line, poking through drainage holes, or tightly circling the pot’s interior signal the need for repotting.
2. Stunted growth: Undersized pots can restrict roots and lead to stunted growth. Slowed growth is normal in winter, but excessive stunting may require repotting.
3. Root rot: Mushy, smelly roots or stems indicate root rot due to overwatering, necessitating repotting in severe cases.
4. Broken pot: If the plant’s pot is damaged, it’s time for a new one.
5. Pests: Severe pest infestations may require repotting to eliminate pests and their eggs, especially effective against fungus gnats.
6. Poor drainage: If water runs through the pot too quickly or the soil shrinks away from the sides, it’s time to repot with fresh soil.
How to Repot Plants in Winter
During warmer months, repotting houseplants outdoors can prevent potting mix spills. In winter, repot indoors as tropical plants are sensitive to cold exposure. To minimize mess, place newspaper under the repotting area before starting.
Step 1: Choose the Right Container
For plants with root rot or pest issues, clean and sterilize old pots for reuse. When upsizing, select a pot only one or two sizes larger than the current one to avoid overwatering and root rot.
Step 2: Remove the Old Pot
Gently remove the plant from its old pot.
To successfully repot plants, sometimes it requires a bit of extra effort, particularly when dealing with plants that have roots that have outgrown their current containers. When faced with this situation, it’s important to be prepared to use a bit more strength and patience to extract the plant without causing damage. Here’s a step-by-step guide to help you through the process:
1. **Extracting the Plant**: Begin by firmly holding the plant’s stems with one hand. With your other hand, gently wiggle the pot free by using a twisting and lifting motion. If the pot is flexible, you can try squeezing its sides or running a butter knife around the inner rim to loosen compacted soil and make it easier to remove.
2. **Inspecting the Roots**: Once the plant is free from its old container, carefully examine the roots for any signs of damage or rot. Any mushy or foul-smelling roots should be pruned away using sterilized pruners or scissors. For roots that are circling tightly, gently tease them apart to enhance water absorption. Always handle the roots delicately and support any delicate stems to prevent accidental breakage.
3. **Repotting the Plant**: Add a few inches of fresh potting mix to the new container. Position the plant’s root ball at the same depth it was in the old pot and fill the container with more soil until it reaches about an inch below the rim. Compact the soil around the base of the plant to keep it stable, and consider using a support stake if necessary.
4. **Watering Adequately**: After repotting, give the plant a thorough watering to help it settle into its new home. Return the plant to its original location, taking note that some plants may exhibit signs of transplant shock, such as wilting or yellowing leaves. This is generally temporary, and with proper care, the plant should recover in due time.
**Frequently Asked Questions**:
– **Is there a bad time to repot plants?**: Spring is typically the ideal season for repotting, but houseplants can be repotted at any time of the year. The only time to avoid repotting is when the plant is in bloom.
– **Should I let the soil dry before repotting?**: It is advisable to have the plant in somewhat moist soil prior to repotting. This helps to ensure that the roots remain hydrated and healthy during the transition.
