When a nursery is established with vaccinated walnut saplings, the trees yield fruits in 1-3 years depending on the variety. Planting ranges should be left wide as the walnut sapling generates big petals. Further, the planting ranges should be determined knowing the variety’s characteristics. For instance, shorter distances may be left as the Chandler walnut sapling (American walnut) generates smaller petals than the other walnut sapling varieties. The distances should be adjusted again knowing the soil characteristics. For instance, the walnut saplings may be planted with shorter distances in locations which are more poor, not rich in respect of nutrition substances, having limited irrigation opportunities; and with longer distances in locations which are deep, humic, ventilated, and sufficient irrigation can be made.
Although the planting distances vary according to the natural conditions and care conditions, the most ideal planting ranges are 10 x 10 m, 8 x 8 m, 8×4 m, 7×7 m. per variety for the walnut saplings.
NUMBER OF SAPLINGS ACCORDING TO THE PLANTING RANGES
- Planting range of 7×3,5 m = 40 walnut saplings are planted per 1 decare
- Planting range of 8×4 m = 30 walnut saplings are planted per 1 decare
- Planting range of 7×7 m = 20 walnut saplings are planted per 1 decare
- Planting range of 10×7 m = 20 walnut saplings are planted per 1 decare
- Planting range of 8×8 m = 15 walnut saplings are planted per 1 decare
- Planting range of 9×9 m = 12 walnut saplings are planted per 1 decare
- Planting range of 10×10 m = 10 walnut saplings are planted per 1 decare
The planting of open-rooted walnut saplings are performed in the winter resting period. Thus, it starts from autumn, and continues until early spring. It is more appropriate to plant the saplings after the leaves are fallen for the open-rooted ones. Bagged / tubed walnut saplings can be planted in twelve months of the year. Walnut sapling holes should be opened with an average width of 60 cm and depth of 60 cm. while the holes for sapling planting are opened, the excavated soil is filled in the sapling holes either solely or mixed with burned animal manures of small or big cattle. In addition, the walnut saplings may be placed after placing composed fertilizer in an amount of 100-150 g. at the bottom of the planting holes and pouring some soil as not to come into contact with the sapling root, providing that to be careful. Before planting, root pruning is performed on the open-rooted walnut saplings. The thick roots are reformed by the root pruning. Hairy roots are not reduced.
Plenty of sap should be given enough for not leaving air inside the soil after walnut sapling planting. If the planting is made in autumn, the tops of the saplings are cut from 40-50 cm, before the eyes start to come up. During planting, the grafting point of the grafted walnut sapling must be 5-10 cm above the soil. In windy regions, the walnut sapling is fastened to stake after planting.
