Almond Tree Not Producing Nuts: Causes For An Almond Tree With No Nuts
By: Mary Ellen Ellis
Almonds are both tasty and nutritious, so growing your own was a great idea – until you realized your tree wasn’t producing. What good is an almond tree with no nuts? The good news is that you should be able to fix the problem with a few simple steps.
Why Won’t My Almond Tree Fruit?
So maybe getting nuts from your almond tree wasn’t the only reason you planted it. It provides shade and height for your landscape, but you also really hoped to get a harvest of almonds out of it. An almond tree not producing nuts can be a big disappointment.
One reason that you may not be seeing nuts yet is that you just haven’t waited long enough. Nut trees can take a few years to begin producing. For almonds, you may have to wait until it is four years old before you see nuts. So, if you got a tree from the nursery and it was only one year old, you may just need to be patient. Once it gets going, you can expect up to 50 years of yields.
Another issue may be pollination. Most cultivars of almond trees are not self-pollinating. This means they need a second tree in the area for cross pollination in order to bear fruit. Depending on the cultivar you chose, you may need to select another one for your yard, so that pollinators, like bees, can do their jobs and transfer pollen from one to the other.
If you don’t have the right combination, you will get no nuts on an almond tree. For example, two trees of the same cultivar will not cross pollinate. Some of the common almond cultivars used to produce nuts are ‘Nonpareil,’ ‘Price,’ ‘Mission,’ ‘Carmel,’ and ‘Ne Plus Ultra.’ One cultivar of almond, called ‘All-in-One,’ will self-pollinate and can be grown alone. It can also pollinate the other cultivars.
If you have an almond tree with no nuts, there is likely to be one of two possible and simple solutions: wait a little longer or get second tree for pollination.

About Walnut Trees
Walnut trees are deciduous trees often grown for their edible nuts. But they are also impressive specimens in the back yard, growing to over 100 feet tall and over 6 feet in diameter. They are great shade trees with spreading canopies and quite long-lived, with life spans of over 200 years.
Walnut trees produce nuts during a two-year process, in which flowers produced in a given year don't mature into nuts until the following year. Female flowers form on the tips of the current year's growth, and on short lateral shoots known as spurs. Although these flowers first appear in early summer, they don't reach maturity until the following spring, usually just after the male flowers appear and release pollen.
According to Penn State University, the nut of the walnut tree is encased in a fleshy green drupe that is the tree's fruit. The walnut crop yield depends on the number of female flowers produced during the first year of the cycle, and successfully pollinated during the second.
