Fertilization of chives: Supplying the optimal fertilizers combination

By means of fertigation, the chives receive all the nutrients needed in order to provide the best yield

 
I. While transplanting

Immerse the transplant plugs in a 2% solution of Poly-Feed 20-20-20 + M.E.
 
II.  Fertigation for the establishment stage

*The increase in the required concentration is meant to compensate for the reduced water uptake.
** pH of the irrigation water should be maintained at 5.8-6.2, and E.C. should not exceed 1.5 dS/m.

 
 
 
Salinity sensitivity: Chives and tarragon are moderately sensitive to high EC and to chloride. Appropriate steps must be taken to avoid salinity buildup and the use of KCl as a potassic fertilizer.
