For many novice gardeners, December is synonymous with downtime. However, seasoned growers understand that this month offers unique opportunities to prepare for a fruitful early spring. Agronomist Victoria Radzevskaya emphasizes that winter is a strategic time to sow certain seeds in the greenhouse, ensuring a fresh harvest as soon as the season shifts.
What to Plant in December for a Spring Harvest
Certain crops thrive when sown in December and can mature over the winter months to provide an early spring yield. The most suitable options include:
- Dill: A resilient herb that can sprout even in colder conditions.
- Lettuce: A quick-growing crop that benefits from cooler temperatures.
- Radish: Known for its rapid growth cycle, radishes can be ready for harvest in just a few weeks.
- Spinach: A hardy green that thrives in the cool, stable environment of a winter greenhouse.
By planting these crops, growers can utilize the otherwise idle winter months to produce high-value, fresh vegetables ahead of the outdoor growing season.
Stock Up on Seeds and Supplies
Winter is an excellent time to purchase seeds for greenhouse planting. Many suppliers offer discounts during the off-season, making it a cost-effective period to stock up. In addition to the crops mentioned above, it’s also wise to secure seeds for summer staples like cucumbers, tomatoes, zucchini, eggplants, and peppers.
Maintenance Tips for Winter Greenhouses
Keeping your greenhouse functional during December requires attention to maintenance, particularly in regions with heavy snowfall:
- Remove Snow Regularly: Accumulated snow can block sunlight, essential for photosynthesis, and may compromise the structural integrity of the greenhouse.
- Monitor Ventilation: While cold air can be a concern, proper airflow prevents humidity buildup, reducing the risk of mold or rot.
- Check for Heat Retention: Insulated layers or thermal screens can help maintain the necessary temperatures for germination and growth.
Why Winter Planting Matters
Planting during winter allows growers to maximize their greenhouse’s potential. Cold-tolerant crops can flourish in controlled environments, ensuring a fresh and early harvest. Additionally, spreading agricultural work throughout the year reduces the springtime rush, improving overall efficiency.
December is far from a dormant month for greenhouse growers. By sowing hardy crops like dill, lettuce, radish, and spinach, and maintaining the greenhouse through proper care, you can turn the quietest season into a productive period. These practices not only provide an early spring harvest but also optimize resources, proving that winter is an opportunity, not a setback.
