Conditions for Cultivation
Filberts are hardy plants which can survive adverse growing conditions.
They should be grown in a soil which is at least 2.4 to 3 m (8-10 ft) deep and will grow optimally in well-draining, fertile loams with a pH between 5.5 and 7.5.
The hazelnut tree is quite hardy but only produces satisfactory crops under moderate climate conditions.
Temperature of minus 10°C is critical, especially if accompanied by wind.
Hazelnuts are more shallow rooted than most fruit and nut trees, and do not tolerate wet soils.
Soils must be moderately fertile and heavy clay soils should be avoided.
Hazels will grow in pH ranging from 4.5 to 8.5, but around pH 7 is ideal.
