This year, we discovered an ingenious and cost-effective method to give our starter plants a head start on the growing season. By using jars and tubs as mini greenhouses, we created a warm, protective environment that helped our plants thrive even before the weather fully warmed up. In this post, we’ll share our experience and tips on how to use everyday items like jars and tubs to create mini greenhouses for your garden. This method is perfect for extending your growing season and ensuring your plants get the best start possible.
Materials Needed
To create your own mini greenhouses, you’ll need the following materials:
Step-by-Step Guide
- Prepare Your Garden Bed: Start by preparing your garden bed or raised bed with rich, well-draining soil. If you’re planting seeds, make sure the soil is loose and free of large clumps.
- Ventilation: On warmer days, lift the jars or tubs slightly or prop them open with small sticks to allow for ventilation. This prevents overheating and ensures adequate air circulation.
- Monitor and Adjust: Keep an eye on the temperature inside the mini greenhouses. If it gets too warm, provide more ventilation or remove the covers during the hottest part of the day. Replace the covers in the evening to retain warmth overnight.
Benefits of Using Jars and Tubs
- Cost-Effective: Using jars and tubs is an inexpensive way to create mini greenhouses. You can repurpose items you already have at home, making this method budget-friendly.
- Ease of Use: Mini greenhouses made from jars and tubs are easy to set up and require minimal maintenance. They can be quickly adjusted or removed as needed.
- Versatility: This method works well for a variety of plants, including vegetables, herbs, and flowers. It’s especially useful for plants that need a warm start or are sensitive to cold.
