Fertilization of tarragon & chives

A complete fertilization program for growing tarragon and chives with Haifa fertilizers

 

I. While transplanting

Immerse the transplant plugs in a 2% solution of Poly-Feed 20-20-20 + M.E.

*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

 

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.
