Weedwhacker said:It can seem a little strange when someone replies to a post from several years back (probably because they didn't notice the date - I know I've done that a few times) -- but on the other hand, it may be just the answer that someone else is currently searching for.
Ain't nothing like carefully crafting out an eloquent response, painstakingly detailed, to answer a time sensitive question posed by an eager gardener...only to realize afterwards that the question is four years old.

Not that I'd ever do something crazy like that...
But yes, the ability to update an older thread with new info/data seems good to me. The threads that aggravate me (a teeny bit) are old threads that suddenly end without a solution/answer/whatever. It's like a novel that was never finished...what was the outcome?.....did the hero tomato plant save the cute cucumber from the clutches of the aggressive pole beans? Did the peppy pepper plant catch the attention of the handsome bumble bee? What happened with the situation of the dump-truck load of chicken manure that was mistakenly dumped on the neighbor's Better-Homes-and-Garden manicured lawn?

Did the collard plants in the front flower bed fool the HOA???

Those unanswered questions bug me lots more than an old thread getting replied to.
People are gonna search. They're (hopefully) going to find. Then sometimes they're going to reply...timely or belatedly. But, whichever, it all adds to the trove of treasure/data here on NGA.
Even if I did spend way too much time replying to that old thread....
