Climatic and soil conditions in Bulgaria are extremely suitable for growing saffron crocus. However, there are some mistakes that can be made during its cultivation.
. Common mistakes when choosing a terrain.
Farmland is not recommended as it is difficult to combat pests – moles, blind dogs, field mices, rats and rabbits. Choose a sunny terrain with a slight slope for draining the water when excessive rainfall. There should be no concave places hiding the risk of swampling and its corresponding rotting of the bulbs. It would be good to use terrain with 6 to 8 pH, soil fertilization is recommended for poorer and sandy soils.
2. Errors when planting bulbs.
Before planting the bulbs must be treated with flungitsid. It deworms and prevents the growth of fungi on the bulbs.
Attention should be paid to the depth of planting. The optimal planting is about 9 – 12 cm. If planting is very shallow – less than 7 cm. – due to the climatic conditions in Bulgaria, there is a risk of frost during the winter. If there is such a problem, you can cover the beds with straw or nylon. When planting is very deep – over 15 cm, the plant reaches harder to the surface. The yield of flowers is lower and the growth of the bulbs is less, but the quality is higher. The distance between the bulbs should not be less than 5 cm in order to have enough space for the bulbs to grow.
3. Watering mistakes.
Prolonged drought requires watering to wake the bulbs. Excessive watering and water retention in rows can cause decay. Irrigation before flowering increases yield.
4. Harvesting mistakes.
It is mandatory to collect early in the morning until the flowers are still closed. If it is done, when the flowers are already dissolved and stagnant, the stigmas are drier and the quality will decrease.
5. Errors when drying.
The optimal drying is carried out at a temperature of 45 degrees for 3 hours in a dehydrator. This is the way to get saturated dark-red color and humidity around 10-12%. These are some of the indicators that will guarantee you a premium saffron. If the temperature is higher there is a risk of blackening and lowering of the quality.
