An experiment conducted in 1990, 2000 and 2001 on Île d’Orléans, Quebec, has determined which plastic mulch (black, silver on black, or thermal/photoselective green) and which shelter (floating cover, mini-tunnel or no protection) results in the greatest earliness and productivity in the off-season strawberry variety Seascape (Fragaria x ananassa Duchesne) in the first and second growing years. The various types of plastic mulch that were used had little impact on total yield, marketable yield and average marketable strawberry weight. Nevertheless, the black mulch is the most satisfactory in terms of its ability to adapt to strawberry plant age and weather conditions. Although using shelters was not effective in increasing earliness in plants in the first growing year, using floating covers (tarpaulins) in the second growing year was beneficial. The various shelters had little impact on productivity, however, no matter the production period
