Planting onions for the winter requires following a few simple yet essential steps to ensure a bountiful harvest. By doing so, you’ll have onions that will be the envy of all your neighbors!
Timing is Key
The most important factor in planting onions for winter is observing the correct planting deadlines. The timing depends largely on the weather conditions. When the air temperature drops to around 5°C, it’s the perfect time to plant winter onions.
Preparing the Soil
The area for onion cultivation should be prepared in advance, allowing the soil to settle. If this step has been overlooked, you’ll need to plant the onions 2-3 cm deeper than the usual 6-8 cm depth to ensure they grow properly.
For optimal growth, add 5-6 kg of humus, 10-15 g of potassium salt, and 20-25 g of superphosphate per 1 square meter of soil as top dressing.
Pre-Planting Preparations
Before planting, sprinkle the bed with 100-150 g of ash per square meter. This will provide additional nutrients and help protect the plants from disease.
Preparing the Onion Sets
To prepare your onion sets for planting, soak them in a weak solution of potassium permanganate for about 30 minutes. This helps disinfect the sets and ensures healthy growth.
By following these steps, you’ll be sure to enjoy a rich and healthy harvest of onions that will impress everyone around you!
