Fall-Lifted Hardwood Stock Survives and Grows as Well as Spring-Lifted Stock
A study just completed shows that time of lifting from the seedbed makes no dif-ference in survival and early growth of several hardwood species--red oak (Quercus rubra L.), black walnut (Juglans nigra L.), sweetgum (Liquidambar styraciflua L.), yellow-poplar (Liriodendron tulipifera L.), and sycamore (Platanus occidentalis L.). Stock was planted on southern Indiana coal strip-mine banks in April of both 1960 and 1961. One thousand 1-0 seedlings grown at Indiana's State Nursery were planted each year. Half had been lifted in the fall and half in the spring. Because of site varia-bility on coal strip-mine banks, survival and growth of fall- and spring-lifted trees were compared in paired rows. Fall lifted seedlings were lifted, graded, and heeled-in after they dropped their leaves. They were taken from the heel-in beds in April and graded again before packing. Spring lifted seedlings were lifted, graded, and packed in April.
