Haskap are tolerant of marginal soils but excel as quality and fertility improve. In their natural environment, Haskap are found in areas with high organic matter. Observations from our trial plot established in 2008 show better growth, larger plants, and higher yields from plants located on better soil profiles. When planting, it is best to seek out sunny locations with a deep layer of topsoil.
Haskap plants are widely adaptable in general, and Phytocultures’ varieties in particular are highly adapted to Canadian climates and soil types. They can reportedly tolerate soils with pH ranges from 4.5 to 8.5, but we aim for an acid soil with a pH of 5.6-6.5. For soils with lower organic matter, a slightly higher pH as a more acidic soil may lessen the uptake of nutrients.
Prior to planting, conduct a soil test in order to determine soil quality and fertility requirements.
