|I have tried numerous times to get Matthiola to grow to maturity. I have both tried them in the garden and in seed starting boxes. The seeds germinate and grow to approx. 2" tall and then the stems weaken and the plant wilts and dies. I'm thinking that it could be the soil preparation and I have tried my best and need some help. I can't seem to find anywhere that mentions the acidity that these plants like? Any ideas?|
|Matthiola, or Stock, are very susceptible to damping-off, a fungal disease. Sow seeds in vermiculite rather than seed starting mix or garden soil, and water from the bottom by setting pots or trays in a tray of water. Provide plenty of air circulation, too. The plants grow well in full sunshine, in moist, well-drained, very fertile, neutral or alkaline soils.
Hope you have better success with your next batch!
