Hi,
I do bury containers with bottom removed. The rodents will have to stay next to the container and continue their way. The roots are thus untouched.
When I spot a gallery ... I trap them - no choice - 1 rodent now means 60 quickly ... or at least 15, that is what I caught when I was not quick enough ...
Here cats that raid the garden look like pregnant cows ... they just chase their own shadows ... the only thing that can't escape them... it seems.
But, it's been three months that I haven't seen a cat. Perhaps a neighbor poisoned the rodents and got the cats too, or people keep them inside because of all the parasites that those thing catch this time of the year (ticks, chips ).
So take a 2 gallon pot, cut the bottom out and plant inside this false pot. If you fear damage at dirt level, put one more container on the dirt to protect the trunk .
If you have tulips ... get rid of them .
Plant jonquils instead, and crown imperial .
Good luck !
I used buried 80 liters trashcan in the past, and I'm going for 2 gallon pots now, because of watering issues during the hot summer weeks.
