Clematis Alpina eaten up
I am not a very experienced gardener, and I just bought a clematis alpina, and a clematis Warsawska Nike, which I planted according to instructions found on the web and on the label. Inclined, shade for the feet, etc.
They are about 40cm apart leaning towards a wooden fence. The young plants were about 40 cm high when I bought them.
After two days, about half the leaves of the alpina were seemingly eaten. The next day, all leaves were gone. The Warsawska Nike is growing fast and does well. I had scattered some anti-slug pellets at their feet, but found no "corpses".
Has the Alpina known predators other than slugs that won't attack the Warsawska ? Can I still revive my alpina, and if not, which other clematis would you recommend ? Thanks a lot for your advice !
My apologies if this topic has already been treated elsewhere, a quick search didn't reveal any obvious thread.
