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.
