We are fortunate in that we can grow most vegetables throughout the year. However, the colder months have their own issues such as less rain and in some areas we have freezing temperatures.
Growing vegetables at these times will bring its own challenges and vegetables will also grow at a slightly slower rate than in the warmer, wetter months.
It's a good idea to get started on your winter vegetables now while the temperatures are still relatively warm, especially if you plan to grow your plants from seed, which usually take about 6 weeks before they can be transplanted into the ground.
In Zambia, the colder months are typically June to August. During these months, some vegetables that can be grown successfully include:
Root vegetables: carrots, beets, and turnips are all root vegetables that do well in cooler temperatures.
Brassica family: this family of vegetables includes cauliflower, broccoli, and cabbage. These vegetables are also well suited for cooler temperatures. Other Leafy greens: kale, spinach, and lettuce can all be grown during the cooler months. They are hardy and can tolerate low temperatures.
Peas: peas are a cool-season crop that can be planted in the early winter and harvested before the hot summer months arrive.
Onions and garlic: both onions and garlic can be planted in the fall or winter and will grow well in cool temperatures.
Additionally, these vegetables may require some protective measures in the coldest months, such as covering with frost-proof cloth, in order to be successful in areas where temperatures drop below freezing.
