Q.Regarding Rosemary Plants in Containers
Have been doing really well. All of a sudden dropping needles. Also some critter is digging nightly. Suggestions?

If your plant is in a container, you might be experiencing winter leaf drop. I've grown rosemary "Arp" for years, and it always drops some foliage as spring arrives. "Arp" is the most hardy variety, and mine have experienced and survived of temperatures in the low teens...BUT, they were extremely well drained, and protected from the wind.
On the critter issue, try to find out what kind of critter. Sometimes an inch of sharp edged gravel is all it takes to discourage them. Good luck.
