Myosotis Mon Amie

Download Plant Culture

Data is gathered from our Elburn, Ill., trials (Zone 5a) for a North American audience. Warm-climate growers: expect 1-2 weeks earlier finishing. Cool-climate growers: expect 1 week slower. Dates based on standard 288 plug size.

Notes/Pitfall Management
Watch for aphids and botrytis. Myosotis are iron loving. Maintain pH 5.5-5.8. Supplement with additional iron as needed. EDDHA chelated iron (aka red iron) is especially useful if pH rises above optimum. After flower initiation grow as cool as possible (down to 40F) to prolong flowering.

Fertilizer Notation: Starting a week after transplant, apply fertilizer at rate 3 (175 to 225 ppm N/1.2 to 1.5 mS/cm) using predominantly nitrate-based fertilizer with low phosphorus. If needed, alternate with a balanced ammonium and nitrate-based fertilizer to encourage growth and balance the media pH. Maintain the media EC at 1.50 to 2.00 mS/cm and pH at 5.6 to 5.8. Avoid high media pH, as this will cause interveinal chlorosis of the young foliage caused by iron deficiency. If the media pH is greater than 6.0, then take corrective measures. Also, supplementing the feed program with iron chelates can be helpful.
Finishing Key Tips: Maintain low pH. Myosotis suffer from chlorosis at high pH. Grow like Primula acaulis. See GrowerFacts for details on how to mitigate chlorosis caused by high pH.
