|We have two dwarf globe blue spruce that are about 4years old and about 2 feet high and 3 feet across. We would like to keep them about that size if possible. Can you tell us how to trim them and if it will damage them in any way. They seem very healthy now.
Thank you Tom Matter
|Picea pungens 'Globosa' grows three to five feet high and five to six feet wide at maturity, but it grows slowly. Spruces do not tolerate much pruning. You can try to keep them small by very light, frequent trimming -- trim just the newest growth. Do not cut them back hard or cut back to bare wood as it will not grow back to cover the resulting bare spot.
