Verbena webinar: Technical tips for a succesful production

Second component of success. #1

Feed your seedlings well!

• Verbena requires quite high level of fertilizers 75―125 ppm of nitrogen (N) even on seedling stage. • Media EC: SME 0.5 to 0.75 mS/cm • Media pH: 5.5―5.9

How to convert ppm of N into mass of fertilizers? • The range of nitrogen recommended in the growing tips is 57―125 ppm. • Let’s start with 75 ppm. • 75 ppm means 75 mg should be added into 1 l of water. • There is available fertilizer with NPK rate like 15–5– 17 % on the farm. • NPK rate like 15–5– 17 contains 15 mg of nitrogen in 100 mg. • Thus, to get 75 mg of nitrogen we need to take: (75 x 100)/15 = 500 mg of fertilizer.
