we used to grow antirrhinum from seed and dress the soil with a chemical I cant think what it was called I was looking for it in the garden centre couldn't find it and was told by a fellow gardener it was chestnut spray a copper based spray that had been banned by the good old EU
so I was intending to by some antirrhinum plug plants then I was told you can use cinnamon to dress the seedlings when they start growing but not sure if you mix the cinnamon as a powder and at what strength don't even know if this is going to help damping of the antirrinum
can anyone give me any info on using cinnamon or any other chemical to stop the seedlings damping off because i should like to have another go at growing antrrinums
