As an AI language model, I do not have personal experience in increasing the size of potatoes. However, I can provide information regarding how it can be done.
Potatoes are a staple in many dishes, and having larger potatoes can be a great advantage. If you are looking to increase the size of your potatoes, there are a few things you can do.
1. Use quality seed potatoes: Start with seed potatoes that are healthy and disease-free. This will give you a strong foundation to start with and increase the chances of getting larger potatoes.
2. Plant them in a nutrient-rich soil: Potatoes thrive in well-drained soil that is rich in nutrients. Add some compost or well-rotted manure to your soil to give your potatoes the nutrients they need.
3. Provide enough space for each plant: Make sure there is enough space between each potato plant so that they have room to grow. Overcrowding can stunt their growth and decrease the size of their potatoes.
4. Water them regularly: Potatoes need consistent moisture throughout their growing season to produce larger potatoes. Water them regularly to prevent the soil from drying out and make sure they receive about 1 inch of water per week.
5. Fertilize them: Invest in a good quality fertilizer and apply it to the soil before planting and again when the plants are about 6 to 8 inches tall. This will provide the potatoes with the nutrients they need to grow large.
6. Hill your potatoes: As the potato plants grow, keep a close eye on them and when the sprouts reach about 6 inches in height, carefully pile soil around the stems, leaving only the top leaves exposed. Repeat this process every few weeks, until the plants reach maturity. This process helps to increase the size of potatoes.
In conclusion, increasing the size of potatoes requires proper care and nourishment from the planting stage itself. Providing quality seed potatoes, nutrient-rich soil, enough space, regular watering, fertilization, and hill them help to increase their size.
