Site selection
Walnuts do best in areas with full sun and deep well-drained
soils (4–6 feet at least). Avoid planting in sites
that stay wet, such as frequently irrigated lawns, flower
beds or soggy, wet soils. Avoid sandy, high-clay, or
shallow soils. Walnuts are adapted to areas with moderate
chilling hours--500 to 1,000 hours below 45° F. Because
of the early blooming habit of walnuts, avoid planting
where late-spring frost occurs, Where late frost does
occur, expect that crops will be light in some years.
If you are planting on a site where soil is shallow because of hardpan, break through the hardpan
when preparing for planting. Do not plant trees too close together, as this may cause poor growth. |
