Planting & Care for Trees – Walnut
Preparation
- It grows best in soil that is deep, fertile, and moist but well-drained.
- Soil texture should be sandy loam, loam, silt loam, or silty clay loam.
- Avoid shallow, dry, sandy, gravelly, or rocky soils.
- Walnuts are often found along streams where periodic flooding occurs in the dormant season.
- Do not try to grow walnut where soils are poorly drained or wet during the growing season or where flooding or ice damage is frequent.
- Walnut grows well on river terraces and hillside benches, and in coves in hilly terrain facing north or east. It will not grow well on steep slopes facing south or west – such sites are too hot and dry.
Opening Plant Material
- B&B - Soak root ball very well.
- Each type of plant has an illustration on how to plant if you scroll down and click on the orange rectangular box “Handling & Plant Guidelines”.
Planting B&B trees
- Plant B&B trees in spring or fall. A good indicator if you can still plant is if the ground is still workable you’re good to go. If a hard frost is expected be sure to hold off on planting.
- Dig a hole at least 6" wider and no deeper than the size of the ball on the plant. Rotate the plant to the proper position. Never lift or move trees by the tops.
- Notice where the base of the trunk flairs out from the tree. This is called the root flair. This root flair should show when the tree is planted. If necessary, add soil under the ball so the root flair is exposed.
- Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer
- Backfill ½ of the hole with soil and completely saturate the soil with water.
- Once the tree is straight and located as desired, cut and remove twine. Then, remove or bend back top ? of metal basket. Lastly, remove exposed burlap from top of ball
- Fill the hole to the top of the ball with soil, then soak well with water and let settle.
- The top of the root ball should be visible and slightly higher than the soil around it.
- Add mulch on top of soil making sure to not put mulch against the trunk or stems.
- See our link below “Handling & Planting Guidelines” for illustrations on planting.
Pruning - After Planting
- B&B - Although it is not essential for B&B to be pruned after planting, a light pruning for shape, to remove any broken branches from shipping, or to thin out a heavily branched plant will help in the transplanting process and in the appearance of your new planting.
Pruning - Through-out the Season
- Prune during the dormant season.
- Wait until trees are 3 to 4 inches in diameter. Trees up to 10 inches in diameter may benefit from clear-stem pruning.
- Do not remove more than 25 percent of the live crown in a single pruning.
- Prune only branches less than 2 inches in diameter, preferably less than 1 inch.
- Prune up to 9 feet high.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the 6 week establishment period, water once per week, unless rains occur.
- Stick your finger into the soil around 3” to check soil moisture.
Watering - Through-out the Season
- After the first season, plants should only be watered during extended periods without rain.
- How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
- Stick your finger into the soil around 3” to check soil moisture.
