Final possibilities for your lack of walnuts this year are that your tree might have been growing too vigorously as a result of over fertilization or over pruning. Fertilizing the grass or plants near your tree could have added too much nitrogen to the soil, resulting in your tree’s energy going towards leaf, trunk and root production ...

Walnut trees sold from nurseries are often grafted, meaning that an upper part of one walnut tree was attached on to the roots of another in order to combine some of the qualities of both. The grafted varieties produce nuts a bit earlier than non-grafted varieties, such as those grown entirely from seed. Grafted walnut trees may produce nuts after ...
Walnut trees are biennial bearing, much like mangos, apricots and avocado. This means that if they have used their available energy and nutrients to make nuts one year, they focus on flower production the next year. There won’t necessarily be nowalnuts harvested during the blossoming years, but there will be fewer. If your tree isn’t bearing many n...
Walnuts trees are partially self-fertile, meaning they don’t need pollen from another tree to produce their fruit. Wind carries pollen from the male to the female parts of the same tree. However, higher walnut yields can be expected if there are other walnut trees planted nearby. Commercial walnut growers will take advantage of this by strategicall...
Walnuts, in keeping with other fruit trees, need both cold and warm weatherin the course of a year to produce fruit. When the temperature drops below 45°F (7°C), this signals a walnut tree to stop growing and enter dormancy for the winter. If the weather is unseasonably warm, the tree’s yearly cycle is thrown out of sync, and it may not produce any...
The growth and overall health of your walnut tree is like a barometer for walnut production. If your walnut tree is growing poorly, walnut production will be poor as well. Walnut trees thrive in full sun, so a walnut tree growing in a shady spot is unlikely to do well or produce as many walnuts. So it’s best to plant them about 50 trees away from t...
If you have a walnut tree, there’s a good chance you’ll see squirrels in it. Walnuts are an exceptional source of protein for squirrels, so be aware that it might be these critters who are responsible for reducing your yield. While walnut shells are incredibly hard (especially the black walnut), chewing through them will pose no difficulty to their...
‘Broadview’ is a compact black walnut tree that is one of the best for producing a reliable yield in favorable conditions. ‘Chandler’ is a black walnut tree with a thinner shell – since the black walnut is especially good to eat, but also especially hard to crack, this is a popular variety. ‘Lake’ is a popular cultivar of the English walnut with re...
The two best-known diseases that can affect walnut production are walnut blight and Thousand Cankers Disease (TCD). Walnut blight is caused by Xanthomonas juglandisand causes black spots to appear on green areas of the tree, particularly the leaves and drooping catkins, including the fruit. It can invade inwards and even affect the quality inner wa...
It very likely will – if you haven’t been applying fertilizer you should start. I recommend fertilizer spikes – they’re slow-release (impossible to get it wrong or overdo it) and can be used for almost any size of tree. Jobe’s are great (particularly the ones for nut trees, designed specifically to stimulate a good crop), as are Miracle-Gro’s. Chec...
Choose a site for your tree in open sun, in well-drained, deep soil.Deeply water your walnut every one to two weeks in warmer seasonsApply a slow-release fertilizerDeter or distract squirrels and crows by providing alternative foodThey commonly grow to 50 feet or taller and about as wide, but specimens of more than 100 feet have been recorded. Black walnut’s large, fernlike foliage provides light, airy shade for those grasses and ground covers unaffected by juglone. The leaves turn bright yellow in autumn, contrasting nicely with the tree’s rugged, dark bark.
The pathogen thrives in wet, poorly drained soils, making it particularly problematic for black walnut trees growing in these conditions. Once the pathogen enters the root system, it causes rotting of the roots and disrupts the tree's ability to absorb water and nutrients.
Nov 21, 2023 · Firstly, take a look at its bark. The bark of a mature black walnut is dark grey-black with deep furrows forming irregular diamond-shaped patterns. This isn’t just aesthetically pleasing; it helps protect the tree from pests and diseases too. Next up: leaf structure.
