Greenhouses and Cold Frames Using Cold Frames
Cold frames are essentially mini greenhouses that are unheated and help extend the growing period for plants. They are perfect for starting cool-season crops like lettuce and spinach early in the spring. You can also use them to protect tender plants from frost or cold weather and even overwinter frost-tender plants.
Cold frames are a great option if you don’t have the space or budget for a greenhouse. They’re also relatively easy to build yourself.
Pros of Using Cold Frames:
- Extend the growing season for cool-season crops. Starting cool-season crops early in the spring under a cold frame allows you to harvest them earlier in the season when they are at their most flavorful.
- Protect plants from frost and cold weather. Cold frames can help protect plants from frost and cold weather, which can damage or kill them.
- Overwinter frost-tender plants. Cold frames can also be used to overwinter frost-tender plants, such as geraniums and fuchsias.
- Inexpensive. Cold frames are relatively inexpensive to build, making them a great option for gardeners on a budget.
Cons of Using Cold Frames:
- Limited space. One of the downsides of cold frames is that they are limited in space, which can make it difficult to grow larger plants or a large number of plants.
- Temperature regulation. Cold frames rely on the sun to heat them, so the temperature inside the frame can fluctuate depending on the weather. This can make it difficult to grow plants that require consistent temperatures.
- Not suitable for all plants. Cold frames are not suitable for all plants. Some plants, such as tomatoes and peppers, need more heat and space than a cold frame can provide.
How to Use Cold Frames:
- Choose a location. The best location for a cold frame is a sunny spot that is protected from the wind.
- Build the cold frame. You can make your own cold frame out of wood, PVC pipe, or other materials. There are many different designs for cold frames, so you can choose one that best suits your needs.
- Prepare the soil. Before planting in a cold frame, prepare the soil by adding compost or other organic matter.
- Plant your crops. You can plant a variety of crops in a cold frame, including vegetables, herbs, and flowers.
- Water and fertilize. Water and fertilize your plants regularly, following the directions on the plant tags.
- Ventilate the cold frame. It’s important to ventilate the cold frame on warm days to prevent the temperature from getting too high.
Step-by-Step Instructions for Using Cold Frames:
- Choose a sunny spot in your garden that is protected from the wind.
- Build your cold frame according to the instructions in the plan you choose.
- Fill the cold frame with a seed-starting mix or potting soil.
- Plant your seeds or seedlings in the cold frame.
- Water the plants regularly.
- Ventilate the cold frame on warm days.
- Harvest your crops when they are mature.

Comparison of greenhouses and cold frames
Cold frames and greenhouses are both valuable tools for gardeners, but they serve different purposes and have unique advantages and disadvantages.
Greenhouses
- Larger structures with heating and ventilation systems
- Maintain a controlled temperature year-round
- Can be used to grow a wider variety of plants
- More expensive to build and maintain
Cold frames
- Smaller, ground-level units
- No heat source
- Extend the growing season by protecting plants from frost and cold weather
- Less expensive and easier to build than greenhouses
Which is right for you?
The best choice depends on your gardening needs and budget. If you want to extend the growing season for specific crops or have a small space, a cold frame is a good option. If you need a controlled environment for year-round cultivation, a greenhouse is a better choice.
Key Takeaways:
- Greenhouses are larger, heated structures that can be used year-round; cold frames are smaller, unheated structures that extend the growing season.
- Greenhouses are more expensive to build and maintain than cold frames, but they offer more control over the growing environment.
- Cold frames are ideal for gardeners with limited space or those who want to extend the growing season for specific crops.
- Greenhouses are a better choice for gardeners who need a controlled environment for year-round cultivation.

Site Selection and Installation
Where and how you position your greenhouse or cold frame plays a critical role in its effectiveness. Here are some key considerations:
Location, Location, Location: Aim for a spot that receives ample sunlight, offers protection from strong winds, and has good drainage.
Facing the Sun: Orient your structure to face south, southeast, or southwest to maximize sunlight exposure during the day.
Drainage Matters: Ensure the ground where your greenhouse or cold frame will sit drains well to prevent waterlogging and root rot.
Easy Access: Place your structure within easy reach to ensure convenient crop management and maintenance.
Key Takeaways:
- Location: Choose a sunny, wind-protected, and well-drained spot.
- Orientation: Face south, southeast, or southwest for optimal sunlight.
- Drainage: Ensure the ground drains well to avoid waterlogging.
- Access: Place the structure within easy reach for convenient management.

Management and Maintenance
Hello there, plant enthusiasts! When it comes to greenhouses and cold frames, management and maintenance are crucial for thriving plants. Here’s what you need to know:
Key Takeaways:
- Temperature control is the heartbeat of your greenhouse or cold frame.
- Watering and ventilation are like breathing for plants, so keep them happy!
- Pests and diseases can be a headache. Nip them in the bud with proper care.
Temperature Control
Imagine your greenhouse or cold frame as a cozy home. You want the temperature just right for your plant pals. Too hot, and they’ll wilt like sad flowers. Too cold, and they’ll shiver like icy lollipops. Use thermometers and ventilation to keep the temperature balanced.
Watering and Ventilation
Water is life, but don’t drown your plants! Let the soil dry out slightly between waterings. Ventilation is like opening the windows for a breath of fresh air. It prevents mold and fungus from ruining your plant paradise.
Pest and Disease Management
The enemy of gardeners everywhere! Inspect your plants regularly for any signs of pests or diseases. Be proactive and use organic methods like neem oil or horticultural soap to keep those nasty critters away.
Remember, happy plants, happy gardener!
