Choosing the optimal time for planting onion seedlings can significantly affect your harvest. Here’s why late October to early November is ideal:
Cold Soil Benefits:
Planting onion seedlings in cold soil, ideally between -1°C to +2°C, promotes bulb growth by up to 25% compared to spring planting. This temperature range encourages root development without premature sprouting.
Preparation and Planting:
Prepare the planting area in a sunny spot. Dig and enrich the soil with compost and ash (1 cup per square meter). Create furrows 3-4 cm deep and space them 12-15 cm apart.
Planting Technique:
Select onion seedlings around 1 cm in diameter or smaller. Plant them vertically in the furrows with a 3-4 cm spacing between each seedling. Cover gently with soil, then top with peat or leaves.
Winter Protection:
In snowy regions, cover the onion beds with snow during winter to insulate the plants. Monitor snowmelt in spring to prevent water stagnation.
Spring Care:
Once temperatures are consistently above -15°C in spring, your onions will thrive. In April, fertilize with a solution of bird droppings or cow manure (1:10 ratio) and cover with a film to protect against late frosts.
Watering Routine:
Maintain regular watering until early July, ensuring the onion seedlings receive adequate moisture until maturity.
By planting onion seedlings in late October to early November under these conditions, you set the stage for a successful harvest, yielding robust onions for your kitchen or market.
