How the Jamuns are warning us

This year, I have seen more jamun (Indian blackberry) fruits in the markets than I have ever seen in the last three decades.

The fruits are literally falling in abundance. Even the trees that bore only a few fruits last year are shedding large quantities of jamuns this year. Trees that were already fruiting heavily are now dropping fruits in huge numbers.

What exactly is happening?

My grandmother used to say only one thing:

"When jamun trees shed fruits in such abundance during summer, that year is usually a drought year."

According to plant science, my grandmother's traditional knowledge is remarkably accurate. In science, this fascinating and somewhat alarming phenomenon is called "Masting" or "Stress Fruiting."

This final effort by a tree to produce the maximum possible fruits, sometimes at the expense of its own survival, is also referred to as "Suicide Fruiting" or a "Bumper Crop."

Let us understand what this means and what science says about it in simple language.

1. The Survival Instinct

As the professor explained, this is nature's way of ensuring the survival of the species. When a tree senses a shortage of underground water or detects signs of significant climatic changes, it shifts into a defense mode.

The tree effectively "realizes" that it may not survive in the future. Instead of investing energy in preserving itself, it channels all its available resources into producing seeds (fruits) so that its species can continue to exist.

2. Suspension of New Growth

During such years, the tree may greatly reduce or stop producing new shoots and branches. This is because maintaining new leaves requires additional water and nutrients. The tree conserves its energy and focuses entirely on producing more fruits.

This is why even the trees that bore only a few fruits last year are now laden with fruit.

3. Grandmother's Prediction and the Science Behind It

My grandmother's observation is remarkably accurate because plants can often detect environmental changes much earlier and more sensitively than humans.

The jamun tree has a taproot system, which extends deep into the ground.

Only when the groundwater level drops significantly do these deep roots begin to experience water stress.

This water stress acts as a signal of an approaching drought or an unusually harsh summer.

Therefore, when jamun trees produce and shed fruits in extraordinary quantities during summer, it may be nature's warning of a forthcoming dry period.

In Short...

The jamun tree is not committing suicide. Rather, it is making a final, intense effort to ensure the birth and survival of the next generation through its seeds.

Nature's cycle is truly astonishing. Here, generations of traditional observations passed down by grandmothers appear to align closely with scientific principles.

So, enjoy the abundance of jamuns this year, but also take seriously this possible warning from nature. It reminds us of the importance of using water and other resources wisely and responsibly.
