Do Trees Ever Skip a Spring and Summer and Not Regrow Leaves Until the Following Year?
Yes, it is possible for trees to skip a spring and summer and not regrow leaves until the following year. This phenomenon is known as "skipping a year" or "alternate bearing".
Causes of Skipping a Year
- Resource depletion: During a heavy fruit production year, trees can become depleted of nutrients and energy, making it difficult to support new leaf growth.
- Hormonal imbalance: Trees produce hormones that regulate fruit and leaf production. An imbalance in these hormones can inhibit leaf growth.
- Environmental stress: Severe weather events, drought, or pest infestations can damage trees, reducing their ability to produce leaves.
- Genetic traits: Some tree species are naturally predisposed to skip a year.
Consequences of Skipping a Year
- Reduced photosynthesis: Without leaves, trees cannot photosynthesize and produce food.
- Energy reserves: Trees draw on stored energy reserves to survive periods without leaves. This can weaken them over time.
- Susceptibility to pests and diseases: Trees with depleted energy reserves are more likely to be attacked by pests and diseases.

- Can all trees skip a year? Yes, but it is more common in certain species, such as oaks and apples.
- How often do trees skip a year? It can vary depending on the species and environmental conditions.
- Is it harmful to the tree? Skipping a year can stress the tree, but it is usually not fatal.
- What can be done to prevent it? Providing adequate nutrients and water, controlling pests and diseases, and avoiding over-cropping can help reduce the likelihood of skipping a year.
- Why is it called "alternate bearing"? Because trees that skip a year typically produce a heavy crop in the following year.
