Please define trickle when watering a Techny Arb
1 - I was told to water a trickle at the base of the arb for 10 minutes twice (if greater than 80) a week for several 5 foot techny arborvitae. Is a trickle approximately the size of a pencil ?
2- After I am done watering if I stick my finger in the ground about 3 inches should it be sticky moist or just moist
3- I have attached what 2 or the arbs currently look like..Is the browning due to watering issues..Should I prune them or will it grow back ? If so can you provide a link on how to prune ? thx
