Why Does Potato Plant Flowering?

Why Does Potato Plant Flowering

Potatoes PRODUCE FLOWERS TO REPRODUCE themselves. Potato plants convert flowers into green fruit that produce seeds inside. This sometimes happens WHEN THE ENTIRE PLANT BEARS MATURE POTATOES.

Potato flower is also TRIGGERED BY PERIODS OF COLD and WET WEATHER. Due to this reason, the flower grows in some zone with cold weather rather than warmer growing zones. 

In warmer zones, such as TEN, ELEVEN, or TWELVE, the potato plants only bloom for a short time or even produce fruit. The FLOWERS WILL FADE AWAY IF YOU LIVE IN THESE ZONES, contrary to others.

Now, this is an interesting question. What to do when the flowers start to grow on your potato plants? Some say REMOVING THEM IS BENEFICIAL for your potato crop. But the truth is- removing potato flowers decreases the size of your potatoes.

It also DEPENDS ON THE HARVEST TIME of your potato crops. Remove flowers WHEN YOU PLANT POTATOES TO GAIN NEW POTATOES. It gives you an advantage in this scenario. 

But if you are GROWING MAIN CROP POTATOES FOR WINTER STORAGE, then it is GOOD TO REMOVE THEM. This way, you will harvest potatoes and potato tubers that are LARGER.

Should You Dig Potatoes Before Flowering

The answer can be a simple ”yes”. But you will be disadvantaged if you start digging your potatoes before the plant blooms. You only GET A GOOD POTATO HARVEST IF YOU SEARCH BEFORE YOUR PLANT STARTS TO WITHER. 

When the potato plant starts to die off, the potatoes have reached their full potential! And now, if you harvest your new potatoes when the plant is still green – You might get SMALL BABY POTATOES. 

There is only one exception to early digging when there is a chance of a long frost time. Then you will at least get some potato yield.

There is nothing to worry if your potato plants are not flowering. Your plant can still produce tubers. The POTATO FLOWERS ARE RESPONSIBLE FOR MAKING GREEN POTATO FRUITS. These fruits look SIMILAR TO GREEN CHERRY TOMATOES! 

The catch here is that potato plant fruit is poisonous, and they are not edible at all. (**Oh, I was thinking of tasting this fruit just like any other ordinary fruit!**). This potato fruit produces solaninea poisonous alkaline

SOLANINE is also PRESENT IN THE GREEN PART OF POTATOES. It should be removed as well before consumption.  

What Happens If the Potatoes are Not Harvested?

You create a PERENNIAL POTATO PATCH if you don’t harvest your potatoes! What this means is EITHER YOUR POTATOES GROW or DIE IN THE GROUND. You might get damaged potatoes in case the soil is wet. Or die when the ground starts to freeze during frost.

If you live in an area with warm and dry weather, ANY TUBER THAT HAS SURVIVED WILL SPROUT AGAIN DURING SPRING! So you’re still not at a loss even if you don’t harvest your potatoes!
