Rocalba organic Stuttergarter onion seeds, large and flat bulbs
It is a strain that belongs to the liliaceous family (Allium Cepa). It produces 7-8cm diameter onions, flattened with white flesh and a yellow-copper skin.
They should be germinated between December and February, transferring the seedling to the final pot or to the ground between January and March when the sprouts are more or less a pencil thick. They are placed in a 25cm x 15cm frame.
For best results we place 2-3 seeds in a seedbed or small pot using medium textured quality soil and a good amount of worm humus and compost. The substrate is watered lightly to moisten it without waterlogging. It is advisable a temperature between 18ºC and 25ºC to ensure that seeds germinate after 12-15 days.
Rocalba organic Stuttergarter Onion seeds, plants up to 20cm high
In order to obtain the largest and best quality bulbs possible, the roots and stems should be cut to a third of their size before planting the plant. This makes it sprout more strongly offering plants up to 20cm high.
Once the onions start to develop, it is vital to be very careful with watering. One must be careful not to over water in order to avoid fungi, also minimise the sudden fluctuations in watering as this could crack the bulbs. It is especially useful to use an automatic irrigation system.
The onions are fattened throughout the spring and summer, being ready for harvest around August-September.
