Again, make sure that plants are healthy going into winter. Check for pests, and treat as necessary. Reduce the frequency and strength of fertilization during winter for plants that are not actively growing. The heating systems in most homes tend to decrease humidity levels. Supplemental mistings or changing the location of plants can improve their health.
Most plants tolerate a few months of lower light levels while overwintering.
But check plants occasionally, looking for symptoms of light deprivation. These include yellowing or pale foliage, dropping or drooping leaves and leggy growth. Take it easy when reintroducing plants to the great outdoors. Sunburn of foliage usually occurs when plants are brought into intense light too quickly. After all danger of frost has passed, acclimatize overwintered plants gradually.
