Yes, the stem is woody and thanks! It should transplant easily then. I would like to start some by the pond shown.
As for the feeder, I fill it from my jon boat. I just tie the boat to the legs and stand on the seat. I can dump it direct from the 50 lb AM bags so, it not too bad. Those are 12' angle iron legs sunk 3' into the ground with the standard, angled dock mounting legs bolted to those (under water) and staked 3' into the ground. Just under the water is a steel plate shelf that I can put one foot on when filling. Being 6'3" helps also.
There has been some theft in our area lately and want to make it difficult to steal. A guy on my road ran out of gas in his push mower by the road. He walked to his garage approx 1200 ft from the road and as he was coming out, gas can in hand, he noticed a truck diving off with his mower in the bed. He told me they may have thought it was for trash pick-up........ but it starts on the first pull! I thought that was very funny!
