How to Overwinter Your Plants
A Complete Guide to Keeping Them Alive During the Cold Season

Winter doesn’t have to mean the end of your beautiful garden! Whether you’re growing tender perennials, tropical plants, or even container flowers, overwintering can keep them safe from frost and freezing temperatures. With the right techniques, you can help your plants thrive through the colder months and come back stronger in spring. In this exclusive guide from Agropearla, we’ll walk you through how to overwinter your plants like a pro.
1. Know Which Plants Need Protection
Not all plants require overwintering, so start by identifying the vulnerable ones in your garden. Tropical plants like hibiscus, tender perennials such as geraniums, and container plants are particularly susceptible to cold. Hardy plants like lavender or hydrangeas can usually withstand winter with little extra care. We always recommend researching each plant’s needs before deciding your approach.
2. Bring Them Indoors
For tropical plants and delicate perennials, bringing them indoors is the best solution. Clean the plants thoroughly, checking for pests, and prune any dead or damaged foliage. Place them in a cool, bright spot—like near a window with indirect sunlight. Don’t forget to adjust your watering! Overwatering is a common mistake when plants are less active in winter.
3. Use Mulch to Protect Outdoor Plants
Outdoor plants can benefit greatly from a thick layer of mulch. Materials like straw, bark, or shredded leaves help insulate the soil, retaining warmth and moisture while preventing frost from reaching the roots. Mulch is a lifesaver for garden beds in cold climates.
4. Consider Plant Covers
Frost cloths, burlap, or even old blankets can be used to shield your plants during freezing nights. For larger shrubs or small trees, you can wrap the base with burlap or create a temporary greenhouse with plastic sheeting. Be sure to remove covers during the day to prevent overheating.
5. Move Containers to Sheltered Areas
Container plants are more vulnerable to freezing because their roots are less protected. Move pots to a sheltered area, like a garage or shed. Alternatively, group containers together and wrap them with bubble wrap or burlap for insulation.
6. Water Wisely
Even in winter, plants need water—but not as much. Water deeply before the ground freezes to give plants a good drink. After that, water sparingly, focusing on keeping the soil slightly moist but not soggy. Frozen soil can trap excess water and harm roots.
7. Prune and Prep
Winter is a great time for pruning and prepping your plants for spring. Trim away dead or diseased growth, but avoid heavy pruning on flowering shrubs, as it might remove next season’s buds. As we always say at Agropearla, proper prep now leads to healthier plants later!
Conclusion
Overwintering your plants doesn’t have to be intimidating. With the right techniques and a little planning, you can protect your green companions from winter’s chill and ensure they return in full glory next season.

FAQ?
1. What’s the best way to overwinter tropical plants?
Tropical plants should be brought indoors. Place them in a bright spot, reduce watering, and maintain a consistent temperature.
2. Do I need to fertilize plants during winter?
Most plants enter dormancy in winter and don’t need fertilizer. Overfeeding during this time can stress them. Wait until spring to resume feeding.
3. How can I protect plants in the ground from freezing?
Use a thick layer of mulch and consider frost covers during particularly cold nights. Mulch insulates the roots and helps prevent freeze damage.
4. What should I do with annuals in winter?
Most annuals are not meant to survive winter, but you can collect seeds or propagate cuttings indoors to replant in spring.
5. Can I overwinter herbs like basil and rosemary?
Yes, but their needs differ. Basil is best grown indoors, while rosemary can be pruned and sheltered in a cool, bright spot.
