Title: Live Oak Suckers Reprise, Austin TX
Answered by: Brigid & Larry Larson
QUESTION:
Referring to an entry dated March 11, 2011 about Live Oak suckers - what happened to the suckers covered with newspaper and cardboard?ANSWER:
Wow - You're checking up on me! I actually think that this experiment was relaively successsful.
For reference, this is the question/answer pair referred to and the recommendation was to clean up the suckers then cover the area with cardboard/newspaper to keep them down.
At the time of the question, we had already prepared and covered the area at least the previous fall. So, in my undocumented experiment:
- For about the first two years this treatment very successfully suppressed the shoots, only a few crept past the edges and were easily removed with garden shears. The cardboard remained relatively intact.
- on years three to four, the shoots would often penetrate the edges of the cardboard and shoot removal made for a full morning job. The cardboard was clearly starting to fall apart.
- I believe this year is year 4+. In selected broad areas the shoots are back and coming up quite healthy [where the cardboard was disturbed]. Other areas are still pretty suppressed, but the cardboard is giving out throughout. I'm thinking that come the Fall a new treatment will be needed.
As I stated before, I consider this a success and intend to keep it going.
