Winter tips and podcast

Winter can be tough on plants, especially on tropical varieties. But with a little preparation, you can protect your garden and keep your plants safe from the cold. Here's how:

Winter Care Tips for Tropical Plants

Cut watering: Reduce watering to prevent root rot. Cold + wet = dead roots.
Water before frost: Thirsty plants are more vulnerable. Water them before a cold night to prevent damage.
Wind protection: Wind is more harmful than temperature drops. Plant near structures like houses or trees for shelter.
Prepare for long cold periods: If cold weather lasts for hours, use all available protection, including Christmas lights and propane heaters.
Don't use dry fertilizer in winter: Heavy fertilizing encourages tender growth, which is more susceptible to cold damage. Sunshine Boosters liquid fertilizers are safe to use year around as their intake is controlled by reduced watering.
Use fabric covers, not plastic: Plastic can cook plants in the sun, while fabric allows better ventilation.

Photo above: we cover our plants in the nursery with a thin synthetic fabric (sintepon) called "frost cloth" or "strawberry cloth". It is light, breathable and allows light and water to go through unlike plastic that creates heavy water pockets.

Prepare for Cold Nights

Wrap plants: On cold nights, cover individual plants or trees with sheets or blankets to shield them from wind chill.
Use Christmas lights: A simple string of lights can add extra warmth, protecting your plants during frosty nights.
Use propane heaters: For added warmth in a larger area, place a propane heater near your plants. Make sure to follow safety guidelines and keep the heater at a safe distance from flammable materials. This can help maintain a few extra degrees of warmth, especially in more open garden spaces or temporary greenhouses. Always ensure proper ventilation to avoid harmful gas buildup.

Large Collections? Build a Temporary Greenhouse

Affordable winter greenhouse: For large plant collections, you don't need an expensive greenhouse. A mobile carport with plastic or fabric covering, costing around $200, can house up to 100 plants!

Photo above: Temporary wrapping around plant collection with a plastic or frost cloth protects from a windchill. It may also win you a few degrees even without a heater. In this particular case, according to our temp sensors, with 30F outside, it was 41F inside this "dome", no heaters used.

Southern Exposure and Garage Storage

Southern windowsills: Compact tropicals can thrive on southern-facing windowsills, getting plenty of sunlight during the day.
Move plants inside: If you have larger collections, move them into a well-lit garage for the colder nights or longer periods.

Key Factors for Survival

Cold duration: Tropical plants can survive brief cold spells but long durations, even above freezing, can be deadly.
Wind-chill: Wind chill can be harsher than the temperature itself.
Exposure: Southern-facing slopes hold heat longer, making them ideal for your plants.
Humidity: Proximity to lakes or oceans can create a milder micro-climate.
Gradual temperature Drops are safer. Plants adjust better to slow temperature changes than sudden cold blasts. Gradual cooling allows plants to prepare, reducing the risk of damage.

Strengthen Plant Hardiness

Health and maturity: Well-established, healthy plants are more cold-hardy.
Boost plant immunity: Use products like SUNSHINE-Epi to improve cold resistance. Apply it before and during cold snaps to protect your plants.
Healthy plant is hardy. Make sure to fertilize your plants on regular basis - healthier and stronger plants are more cold hardy.

With these steps, you can protect your plants and help them survive the winter months. Stay warm and keep your garden thriving!
