Saffron crocus is a perennial plant. It can be grown without transplanting for maximum 4 years. Each year the saffron crocus form new bulbs around the initially planted one. Their number depends on the size of the originally planted bulb. As a result, for a period of 4 years, the amount of bulbs grows significantly, and each year the yields are increasing. At the fourth year the terrain is planted. The bulbs are removed mechanically, with a potato picker, etc. This is done during the lethargy period in June, when the leaves of the bulbs have dried out. Bulbs are also checked for contamination and diseases. If not planted immediately, the bulbs should be stored in a dry, ventilated and dark place. On the same area, the required number of bulbs are planted. With the rest of the bulbs a new terrain can be planted or they can be sold. It is good to use a terrain for a maximum of 8 years, then it is advisable to plant another crop. Saffron should be included again in crop rotation at least after 5 years, and the best will be after 10 years.
Transplanting of saffron
Saffron crocus is mainly fertilized before transplanting and then once again in spring and autumn when the green leaves appear above the ground. Saffron should not be fertilized with fertilizers containing chlorine, sodium and heavy metal contaminants (lead, cadmium, etc.), because when the dried spice is purchased, analyzes are made for residues of contamination and damage to quality.
Saffron is extremely sensitive to salting. It is advisable to perform soil analysis and consultation before fertilizing.
It is well influenced by the addition of nitrogen – increases the period of active bloom and plant reproduction. Phosphorus is also necessary for normal growth because it influences the shape and color of the flowers and plays an important role in the plant’s respiration and photosynthesis. The potassium increases the height of plants and the number of flowers. It also stimulates the yield and the resistance of stress – diseases, drought, excessive humidity, and extreme temperatures. Magnesium, calcium, manganese, etc. can also be added. When the leaves appear in September, foliar fertilization increases the yield and flowering of crocus.
Saffron grows in areas with a Mediterranean and continental climate. The history of its development shows that the plant adapts very well and at extreme temperatures – up to 40 degrees in summer and up to -20 degrees in winter.
In the autumn, blooming of the saffron crocus starts about 40 – 50 days after planting of the bulbs. If the bulbs are from a previous year and had spent the winter in the ground, they start their flowering since the beginning of October.
