Greenhouses and Cold Frames: Winter Greenhouse Plants
During the harsh winter months, greenhouses and cold frames provide a lifeline for plant enthusiasts, allowing us to cultivate a vibrant array of flora despite the unforgiving elements. These structures serve distinct purposes, providing optimal conditions for protecting and nurturing our beloved plants.
Greenhouses stand as enclosed structures, equipped with heating and lighting systems that maintain a controlled environment. They offer a haven for plants, shielding them from extreme temperatures and providing an extended growing season. With proper insulation and heating, greenhouses enable us to cultivate year-round, ensuring a continuous supply of fresh produce and ornamental blooms.
Cold frames, on the other hand, are unheated structures that rely on sunlight and ground energy to provide warmth. While they lack artificial heating, cold frames still offer protection from frost and wind, extending the growing season for hardy plants. They are particularly useful for overwintering plants and hardening off young seedlings in spring.
When selecting plants for your winter greenhouse or cold frame, consider their hardiness and adaptability to indoor conditions. Some ideal choices include:
- Leafy greens (lettuce, spinach, kale)
- Root vegetables (carrots, radishes, beets)
- Herbs (parsley, chives, thyme)
- Flowering plants (pansies, violas, calendula)
Remember to adjust watering and fertilizing schedules to suit the reduced growth during winter. Regularly monitor your plants for signs of pests or diseases, taking prompt action to prevent their spread.

Adjusting watering frequency
During winter, your greenhouse plants will need to be watered less frequently than in the summer. Depending on your specific climate and the types of plants you’re growing, you may only need to water them once or twice a week.
Overwatering can lead to a host of problems, including root rot, fungal diseases, and nutrient deficiencies. So it’s important to check the soil moisture before you water and only water when the top inch or two of soil is dry.
Here are a few tips for watering your greenhouse plants in the winter:
- Use a moisture meter to check the soil moisture before you water. This will help you avoid overwatering.
- If using a watering can, water slowly and deeply, allowing the water to soak into the soil.
- Water at the base of the plant, avoiding the leaves, to reduce the risk of disease.
- If you have a lot of plants to water, consider using a drip irrigation system. This will help you save time and water.
By adjusting watering frequency, you can help your greenhouse plants stay healthy and thriving all winter long.
Key Takeaways:
- Water plants less frequently during winter.
- Check soil moisture before watering.
- Water deeply but sparingly.
- Use a moisture meter or drip irrigation system for efficiency.
- Avoid overwatering to prevent root rot and disease.

Fertilizing during winter
In the winter months, your greenhouse or cold frame plants will need less fertilizer than they do during the summer. This is because they are not actively growing, so they do not need as many nutrients. However, it is still important to fertilize your plants occasionally during the winter to keep them healthy and prevent them from becoming nutrient deficient.
Here are a few tips for fertilizing your greenhouse or cold frame plants during the winter:
- Use a slow-release fertilizer. Slow-release fertilizers release nutrients over a period of time, so you don’t have to fertilize your plants as often. This is especially important during the winter, when you may not be able to get to your plants as regularly.
- Choose a fertilizer that is low in nitrogen. Nitrogen is an important nutrient for plants, but too much nitrogen can cause them to grow leggy and weak. A fertilizer with a low nitrogen content will help to prevent this.
- Fertilize your plants less frequently. During the winter, you should only fertilize your plants once a month, or even less often.
- Water your plants well before and after fertilizing. This will help to dissolve the fertilizer and prevent it from burning your plants.
Key Takeaways:
- Greenhouse and cold frame plants require less fertilizer during the winter months.
- Slow-release fertilizers are ideal for winter fertilization.
- Choose a fertilizer with a low nitrogen content.
- Fertilize your plants less frequently during the winter, about once a month or even less often.
- Water your plants well before and after fertilizing.
Monitoring for Pests
During the winter months, your greenhouse or cold frame can be a haven for pests, which can quickly damage or even kill your plants. That’s why it’s important to monitor for pests regularly and take steps to control them if necessary.
Here are a few ways to monitor for pests in your greenhouse or cold frame:
- Inspect your plants regularly. Take a close look at your plants, especially the undersides of leaves, for any signs of pests. Common pests to watch for include aphids, mealybugs, spider mites, and whiteflies.
- Use yellow sticky traps. These traps are coated with a sticky substance that attracts and traps flying pests. Place the traps near your plants and check them regularly for pests.
- Use pheromone traps. These traps emit a scent that attracts specific pests. Once the pests are attracted to the trap, they become stuck and can be easily removed.
If you find any pests in your greenhouse or cold frame, it’s important to take steps to control them as soon as possible. There are a variety of methods you can use to control pests, including:
- Biological control. This involves introducing beneficial insects or other organisms into your greenhouse or cold frame to prey on or parasitize the pests.
- Chemical control. This involves using pesticides to kill or repel pests.
- Cultural control. This involves using methods such as crop rotation, sanitation, and proper watering to make your greenhouse or cold frame less attractive to pests.
By monitoring for pests regularly and taking steps to control them, you can help to keep your plants healthy and thriving all winter long.
Key Takeaways:
- Regularly inspect your plants for signs of pests.
- Use yellow sticky traps and pheromone traps to attract and trap pests.
- Implement biological, chemical, or cultural control methods to manage pests.
- Monitor pest populations over time to identify potential outbreaks.
- Consult with experts or resources for pest identification and management recommendations.
