What to Plant Outdoors in December
In the northern hemisphere, December brings chilly temperatures and frosty conditions, making outdoor gardening challenging. However, there are still a few planting options to consider during this time, particularly in regions with milder climates or when utilizing protective measures like cold frames or row covers. Here are some plants you can consider planting outdoors in December:
Garlic: December is an excellent time to plant garlic cloves for a summer harvest. Prepare the soil, separate the cloves, and plant them with the pointed end facing up.
Onions and Shallots: Similar to garlic, onions and shallots can be planted in December for a future harvest. These hardy crops can withstand winter temperatures and provide a flavorful yield.
Perennials: In areas with mild winters, you can plant certain perennial flowers and shrubs in December. Select cold-hardy varieties such as pansies, hellebores, and winter-blooming heathers to add color and interest to your garden.
Bulbs: While it’s late in the season, you may still be able to plant certain spring-blooming bulbs in December. Look for hardy bulbs like tulips, daffodils, and hyacinths that can tolerate the winter conditions.
Cover Crops: Consider sowing cover crops in your garden beds during December. Cover crops like winter rye, clover, or vetch can protect the soil, suppress weeds, and improve its fertility when turned over in the spring.
Trees and Shrubs: December is a suitable time to plant trees and shrubs in regions with milder climates or when utilizing protective measures. Ensure you choose varieties that are suitable for your specific region and climate.
Fruit Trees: In regions with mild winters, you can plant bare-root fruit trees in December. Apples, pears, cherries, and other fruit tree varieties can establish their root systems during the dormant season.
Rhubarb: Rhubarb is a perennial vegetable that can be planted in December, especially in areas with mild winters. Prepare the soil and plant rhubarb crowns, leaving enough space for them to spread as they grow.
Keep in mind that the planting options in December may vary depending on your specific location and climate zone. It’s crucial to consider local weather conditions and frost dates when deciding which plants to try. Additionally, providing proper winter protection, such as mulching or using row covers, can help protect young plants from extreme cold.
