Answer: 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!
