I pricked out lots of my bedding plants last weekend. The seeds were sown in a heated propagator and pricked out into 5X8 individual seed trays. Every one of my French Marigolds are fine, as are my Geraniums and Antirrhinums, but I had a whole tray of Mimulus and every one of them are gone, as are my Nemesia.
How can I avoid this?
