We expect it to last the life of the orchard (30-50 years). As for the leaching from plastic it usually happens in the first few months so using a thin film like 1 mil, as is used for vegetable production, leaches out during the season and again the next and the next with successive new plastic mulches. Using a thick one mulches in the first few months and no more in the following years. It's a choice, I chose work saving with the mulch. If you have less than 100 trees go with organic mulch and reapply it every 1-2 years. If you have more than 100 trees and want to go with organic mulch invest in a mulch spreader. There are good ones that fit in orchard rows.
