Winterizing House Plants
The days are getting shorter and the nights a bit cooler. It is time to start thinking about bringing in any houseplants that have been outside for the summer. Fall is a great time to do maintenance on your houseplants so their rejuvenated by spring.
- You will need to bring your plants indoors before nighttime temperatures dip below 45 degrees (F). Most tropical plants will suffer damage at temperatures below 40 degrees, a few even below 50 degrees.
- Inspect plants for insects and diseases, and treat as appropriate before bringing plants back inside. Soaking the pot in a tub of lukewarm water for about 10 minutes will force insects out of the soil. Give your plants a shower before bringing them in. With your garden hose set on mist or shower, spray the leaves, undersides too.
- If necessary, re-pot plants into larger containers. Always making sure to go one size up.
Example: 4 inch into 6 inch, 6 inch into 8 inch.
- Trim off any dead leaves or branches with a sharp pair of scissors or hand-held pruning tool.
- To prevent shock when you bring houseplants back indoors, expose plants gradually to reduced lighting. If plants are in a sunny location, move them into bright shade for several weeks before the anticipated moving date. Once back indoors, it is very common for the plant to drop a few leaves. When this happens don't panic, it's normal!
- Most houseplants will not need to be fertilized during the winter months with the exception of African Violets.
