What fertilizer is the best for growing potatoes?

The best fertilizer for growing potatoes is a balanced one, such as a 10-10-10 fertilizer. This means that it contains 10% nitrogen, 10% phosphorus, and 10% potassium. Nitrogen is important for vegetative growth, phosphorus is important for root growth and tuber development, and potassium is important for overall plant health.

In addition to a balanced fertilizer, potatoes also benefit from the addition of organic matter, such as compost or manure. Organic matter helps to improve the soil structure, aeration, and water-holding capacity. It also provides a slow-release source of nutrients.

When to fertilize potatoes

Potatoes should be fertilized at three different stages of growth:

* At planting: Apply a starter fertilizer, such as a 5-10-5 fertilizer, at the time of planting. This will give the potatoes a boost of nutrients to help them get started.

* At hilling: Hill the potatoes when they are about 6 inches tall. This will help to support the plants and encourage tuber development. At the same time, apply a side dressing of fertilizer, such as a 10-10-10 fertilizer.

* At flowering: Apply a final side dressing of fertilizer, such as a 10-10-10 fertilizer, when the potatoes are flowering. This will help to boost tuber production.

Fertilizer Tips for Potatoes:

* Do not over-fertilize potatoes, as this can lead to problems such as vine growth, poor tuber development, and disease.

* Water potatoes regularly to help them absorb nutrients from the fertilizer.
