The walnut is a very valuable tree not only for its excellent fruits (walnuts) but also for its wood, of great quality and valid for making a lot of furniture. It can reach 27 meters in height, with a diameter that can be 4 meters. It has both male and female flowers, the former without being protected by the leaves, while the latter are grouped in a bouquet.

From the female flowers the walnut is born, a fruit that is large and inside which you will find the delicious dried fruit that is used both to give a special touch to any dish and to eat it raw without anything to accompany it. The walnut tree blooms in early spring, while the fruits usually arrive in the fall. If you want to know everything about the cultivation and care of walnut , keep reading this AgroCorrn article.

Walnut care

The basic cares for walnut are:

  • Temperature : it does not require an exact temperature to be able to develop, but it is very sensitive to frost, especially those that arrive in spring and early autumn. You also have to be careful with very high temperatures since if they occur in low humid climates they will cause the nuts to be empty.
  • Soil : it adapts very well to all types of soil, although the one that suits it best is the one that is well drained and has a neutral pH. If you plant bare roots you will have to use an organic substrate and add a growth stimulator for the roots.
  • Irrigation : it is the most important care and to which the most attention must be paid so that the fruits are of good quality. Sprinkler irrigation is not a good option as it can lead to disease, so it is better to use a hose or drip. There must always be humidity but without waterlogging.
  • Compost : you have to apply it before planting the tree, and then fertilize regularly with an organic fertilizer that is suitable for this type of tree.
  • Pests and diseases : those that most often affect this tree are the aphid or woodworm or nut worm. There are some diseases that are specific to walnut trees, such as bacteriosis (appears with overhead irrigation) or black disease.
  • Pruning : it is done mainly to control the size of the tree, to remove old branches and make room for new ones and also to enhance fruiting.
