Today I paid a large amount of money to a major university (cooperative extension ) in order to enhance my knowledge of shrubs. I was told by the main speaker, that the gas hedge trimmer was the enemy. He suggested that we should trim HEDGES, listen to this- by hand- manually, one branch at the time..... He actually went to the gardens and showed us hedges trimmed this way. They looked Uneven-- to say the least. The only good thing he claimed is that it is harder to see the tips because you are trimming deep. And he claims he has to only trim once a year, except that in my opinion it takes about 100 times as long as others that use hedge trimmer. Seriously, should I ask for a refund? Also, we were asked to bring hedge trimmer and when we got therr, we are told that "the hedge trimmer" is the enemy. Fortuantely the other 1/2 of the workshop focused on trees & was taught by an Arborist with real life experiences. YEs, i am going to ask for a 50% refund. Now, should I ask for my money back?
