Reasons for an avocado tree without fruit So, one of the reasons why an avocado doesn't produce fruit is simply because it's not a mature grafted variety. In addition, avocados planted in USDA zones 9 through 11 can bear fruit, but if you are in a colder region, the tree may survive but never bear fruit. A mature avocado tree usually produces between 200 and 300 fruits per year. However, since the avocado tree alternates its production, it can produce more fruits one year and much less another.
Like apples, avocado seeds themselves don't normally produce avocados. Any avocado seed can grow an avocado plant, but not necessarily a fruit tree. While planting the tree outside should give it enough space to grow, unfortunately, it won't guarantee that it will bear fruit. In increasingly warm climates, such as California (where Hunter is located), avocados remain on the tree from April or May until January of the following year.
Another thing to keep in mind if you live in a colder climate is that mature avocado trees can reach up to 35 feet tall. An avocado tree with type A flowers opens like an active female in the morning of its first day, while the male flower actively opens in the afternoon of the next day. Once they reach a certain size, avocado trees cannot be easily transplanted, which means that moving an avocado tree once it is in the ground is not recommended, because its root system is so wide. Indoor avocado trees will do best if they are sprayed daily, especially during the winter months when the heating is on.
Unlike other trees that start producing fruit as soon as they reach a certain height, avocado trees can take between five and 13 years to bear fruit. Growing an avocado tree from seed requires a lot of patience and a touch of luck, but if you're one of the few to be rewarded with fruit, it's worth it. In addition, it's important to separate avocado trees from other plants; at least several feet apart, give fruit plants room to grow. According to Hunter, avocado trees are more likely to grow in a moderate climate that has a temperature range between 40 and 90 degrees Fahrenheit year-round.
According to the University of California Cooperative Extension, when temperatures fall below 70 degrees Fahrenheit, daily flower openings become irregular, so sometimes a single tree with type A or type B flowers can have flowers in the male and female stages at the same time. Hunter says the best way to strengthen the tree and protect it from sunburn is to ensure that its soil has enough nitrogen. But if yours grows indoors, it's beneficial to shake it up a bit to spread the pollen, as you won't have bees or wind to do it for you. It's completely normal for an avocado tree to flower but not bear fruit, which makes it fun to watch the avocado grow.
