Last year i grew sunflowers from seed, i had 12 plants. I planted them in the garden for my litlle son.
We where proud of them and the morning after planting we went to say them goodbey.....it was a googdbey indead!!!...: all 12 had been eaten by snails. They where about 10 cm high, so the snails had a good meal, there was really nothing left to see, just the soil.
Now i have grown 16 plants [ 4 different ones] and i will sure use escar-go. [ it is bio, not dangerous for other animals.]
