Snails can be a problem even with reduced irrigation
by Curtis Smith, PhD, NMSU Estension Horticulture Specialist
Q. Late last gardening season we suddenly had a lot of brown snails. We picked them off and “drowned” them and were careful to not put any garden waste in our compost pile.
I understand that over-watering might well be the cause. Recently you wrote an article about efficient watering and recommended drip irrigation rather than spray. We have had spray but could probably convert to drip fairly easily. Would this be a good move? I realize that we cannot overwater again, but would drip, plus mulch further encourage snails?

A. Snails can be a big problem once you have them. The problem increases when there is adequate water, but they can survive rather long periods without water. Minimized watering as appropriate for xeriscapes will help a little, but they will take advantage of every irrigation. You will just limit the habitat with adequate moisture when you use drip irrigation and irrigate infrequently. Yes, organic mulch will also be beneficial to the snails, but it will also be beneficial for the garden. (continued at SW Yard and Garden column February 6, 2010)
