Question
READY TO PLANT OUR ANNUALS.SOME SURVIVED 5 MONTHS AS WE LIVE IN SOUTHERN FLORIDA. OUR QUESTION IS, THE ONES THAT SURVIVED ARE LONG AND STRINGY. THE FLOWERS ARE STILL ON THE
LONG STEMS, CAN WE CUT OR PRUNE THEM AND NEW ONES WILL GROW BACK?  

Answer
Don,
It kind of depends on what annuals you have, but in general, if you cut them down by one half to two thirds annuals will usually put on new growth and bloom more.  If the annuals you planted like cooler temperatures (allysum, million bells, ageratum etc) they should take off now that winter is here.  If they are annuals that like warmer temps (zinnias, marigolds etc) they might not do as well.  Others, such as petunias, impatiens and the like might take a short resting period and then grow again and bloom gangbusters!

After you cut them back give them a MILD liquid fertilizer after you've watered them well (never fertilize a thirsty plant) and from then on use fertilizer according to the directions.

I hope this helps!
