Growing Premium Quality Lapins Lynn E. Long Professor, Department of Horticulture Extension Agent Oregon State University Wasco County Extension Growing Premium Quality Lapins Comments from Hugh Dendy's presentations at the Oregon Horticultural Society and Wasco County Cherry Horticulture programs are summarized below. Over the years, Lapins has commanded a premium price for him due to dependably high quality fruit. Dendy stated that fruit quality problems he has observed have been due to improper growing conditions, stress factors on the tree or developing fruit, or to improper harvest timing.
Lapins are self-fertile with a corresponding tendency to overset.
Fruit is often formed on branch buds rather than spurs causing a high incidence of blind wood in subsequent years. This produces a relatively high proportion of fruit to leaves. Bearing trees should be discouraged from over-setting by dormant pruning, pruning hard, removing weak and pendant growth and selecting upright, vigorous wood. Shading Caused by excessive vegetative growth Caused by high planting densities Limit nitrogen applications to produce moderate, not excessive growth. This changes the distribution of growth regulators producing more fruit on spur wood and less on branch wood.
