Step-By-Step Guide to Growing Onion Rijnsburger Seeds
Starting Your Onion Journey
Are you eager to grow some onions? Let’s get started. First, you need to decide on your sowing method.
When and Where to Sow
For those interested in indoor sowing, the ideal period is between February and April. During this time, maintain a cosy temperature of around 14°C. Alternatively, you can opt for outdoor sowing in April. In both cases, make sure to:
- Plant your seeds about 1.5 cm deep
- Space the rows about 30 cm apart
Taking Care of Your Onion Seedlings
Once your seeds have sprouted, there are some key steps to follow.
Indoor Seedling Care
Firstly, transfer the seedlings into individual pots or modular trays. Secondly, come April, you’ll want to move them to a cold frame to harden off before transplanting them outside.
Outdoor Seedling Care
For outdoor-sown seeds, the first thing to do is thin out the plants. Eventually, aim for a final spacing of 15 cm apart.
Approaching Harvest Time
As your plants grow, you’ll start to think about harvesting.
The onions usually mature between August and September. So, when that time comes, be careful while pulling thinnings to avoid attracting onion flies.
Storage and Beyond
Wondering what to do after harvest? Well, you’re in luck.
Storing Your Onions
These onions have excellent long-term storage capabilities, thanks to their solid white flesh and golden skin.
