When you see flowers on your potato plants, I recommend cutting them off for two main reasons. First of all, you don’t want the flowers to produce a fruit that small children or pets might be tempted to eat. Secondly, pruning the flowers is a great way to increase production of spuds.
How do you increase the yield of potatoes?
When the potatoes have sprouted and grown foliage about 8” tall, you should begin “hilling” the plants by mounding the fluffy soil on either side of the trenches up around the stems of the plants. As long as there is some foliage sticking out they’ll keep growing, and the more you hill, the more potatoes you’ll get.

You can trim the tops of your potato plants but only when the potato tubers are ready for harvest. If you trim the tops before this time, the potato plants won’t have sufficient foliage to get enough nutrients by making their own food.
Does hilling potatoes increase yield?
That said, hilling does tend to end up increasing the yield of potato plants because in addition to preventing potatoes from going green, it also controls weeds, improves drainage, and raises the temperature of the soil.
What causes low potato yield?
Daytime heating of roots is one reason why potatoes grown in above-ground containers may fail in warm summer climates. Potatoes can take warm air temperatures, but when the roots warm up too, productivity plummets.
Should potato flowers be removed?
When you see flowers on your potato plants, I recommend cutting them off for two main reasons. First of all, you don’t want the flowers to produce a fruit that small children or pets might be tempted to eat. Secondly, pruning the flowers is a great way to increase production of spuds.

Which fertilizer is best for potatoes?
A month or two after they’ve been planted, potatoes need lots of nitrogen, so a fertilizer with an NPK of 34-0-0 is the best choice. An NPK of 12-12-17 or 14-7-21 is best for the last couple of months before harvest when the plants require more potassium.
When should you stop watering potato plants?
Stop watering your potato plants about 2-3 weeks before harvest, or when you first see the foliage on the plants starting to turn yellow. Make sure to harvest your potatoes on a dry day when the soil is dry—harvesting potatoes when wet or damp can cause the potatoes to rot more easily in storage.
How do you increase the size of a tuber on a potato?
Anything that prolongs a healthy leaf canopy will increase the average tuber size. Correct balanced nutrition is important for increasing potato tuber size. The nutrients nitrogen, phosphate, potassium, calcium, magnesium and manganese have all been shown to affect potato tuber size.
How long after potatoes flower Are they ready?
Most early potato varieties will produce flowers in June, quite pretty ones too. Many are white, but they come in purple and pink too. Once the flowers start to go over, or the unopened flower buds drop, you know that the potatoes are ready to harvest. This will take anywhere from eight to twelve weeks after planting.
Do you pinch out potato flowers?
To trim your edible potato plants, pinch off the blossoms as soon as they appear on the plant, or snip them off with shears. Blossoms are an indicator that the plant is mature and small tubers are formed. Removing the flowers removes the competition and fosters larger, healthier potatoes.
What do I do when potato plants flower?
It’s best to dig potatoes when the soil is dry. This potato plant is flowering, which indicates that the tubers are forming underground. Keep plants well watered during and after flowering.
Should I cut off potato fruit?
As a general rule, you don’t need to remove potato fruit – unless you’re worried that someone may inadvertently eat enough to poison themselves. Or you plan on harvesting the seeds and trying your hand at growing some interesting varieties of tuber.
Why are my potatoes growing so tall?
Potato plants can grow too tall when they have been given too much fertilizer, especially when it’s rich in nitrogen. Nitrogen can encourage potato plants to develop more than usual, and this is evident in the overgrowth of their tall green shoots above the ground.

A potato plant flowers as it gets closer to maturity and signals that “new potatoes” (small tubers) are ready for harvest. Cold, wet weather can also make potato plants flower.
