I grew zinnia from seed for the first time this year - and am so disappointed. Despite all precautions, they were initially munched relentlessly by snails. But some survived and buds appeared. I checked them every day and can’t understand why, on many of the plants, the stem just below each bud has turned brown and mushy. No flowers, obviously. Should I try again next year?
Planting anything out too early is often a problem, especially with plants which prefer lighter conditions for their feet, and lots of sun.
I live in west central Scotland - not where that photo is...
I think they really require quite a bit more patience than even many other tender annuals, my first lot gave up after a cool spot of weather the second got munched.
I'm going to try again next year because they are really nice looking flowers.
