Irrigating Rosemary Plants
Rosemary is a draught tolerant plant. However, when someone grows it commercially, it is beneficial not to let the soil dry out completely for a long time, as this will have a negative effect in production of plant mass.
There are two rules of thumbs concerning the water requirements of rosemary plant. The first is that newly established plants (started from seeds or cuttings) need much more water than mature plants. Young plants need artificial water supply in order to develop a strong root system. After this, in many cases, mature plants can rely solely on rainfalls, provided the annual precipitation exceeds 450 mm. However, this depends also on soil texture and humidity levels. The second rule of thumb is that the rosemary plant often suffers from root rot and fungal diseases caused by excessive water. Consequently, we must be cautious not to over irrigate.
Many farmers apply 3-4 irrigation sessions during summer months, in areas with very hot summer and no rainfalls. In other cases, drip irrigation is applied and the plants are watered for 20 minutes once a week, especially during the summer months.
