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.
