# The Ultimate Guide to Growing Your Own Potato Plant
Growing your own potato plant from seed potatoes is a rewarding experience, offering a fresh supply of delicious, homegrown tubers. This guide will walk you through the entire process, from selecting your seed potatoes to harvesting your bounty. Whether you have a sprawling garden or a small balcony, potatoes are a versatile and relatively easy crop to cultivate. This guide aims to provide a comprehensive overview, ensuring you have all the knowledge needed for a successful potato harvest.
The journey begins with choosing the right “seed potatoes.” These aren’t true seeds but rather small, whole or cut pieces of larger potatoes that have been specifically grown for planting and are certified disease-free. Varieties come in a vast array of colors, sizes, and flavors, each suited to different culinary uses and growing conditions. Consider factors such as maturity time (early, mid-season, or late season), disease resistance, and your personal taste preferences when making your selection.
For a healthy start, ensure good quality seed potatoes. It is crucial to “chit” your seed potatoes before planting. This involves pre-sprouting them in a bright, cool location for a few weeks. This process encourages the development of short, sturdy sprouts, which will give your plants a head start once planted.
Planting Your Potato Plant
Choosing the Right Location and Soil
Potatoes thrive in full sun, requiring at least six to eight hours of direct sunlight daily. They also prefer well-draining, fertile soil with a slightly acidic pH (between 5.0 and 6.0). Before planting, amend your soil with plenty of organic matter, such as compost or well-rotted manure, to improve drainage and nutrient content.
Hilling Your Potato Plant
One of the most critical steps in potato cultivation is “hilling.” As the potato plant grows, you’ll need to gradually mound soil around the base of the stems. This process serves multiple purposes: it encourages more tubers to form along the buried stem, protects developing tubers from sunlight (which can cause them to turn green and produce solanine, a toxic compound), and improves air circulation. You’ll typically hill your plants several times throughout the growing season.
Potatoes are members of the nightshade family (Solanaceae), which also includes tomatoes, peppers, and eggplants.
Caring for Your Potato Plant
Watering and Fertilizing
Consistent watering is key, especially during the critical tuber development stages. Aim to keep the soil consistently moist but not waterlogged. Drought stress can lead to misshapen tubers and reduced yields. Fertilize your potato plants with a balanced fertilizer or one that is lower in nitrogen and higher in phosphorus and potassium once the plants reach about 6-8 inches in height. Over-fertilizing with nitrogen can lead to lush foliage at the expense of tuber production.
Pest and Disease Management
Potatoes can be susceptible to various pests and diseases. Common issues include Colorado potato beetles, aphids, blight (early and late), and scab. Regularly inspect your plants for any signs of trouble. Companion planting with certain herbs like basil or marigtang can help deter some pests. Crop rotation is also essential to prevent the build-up of soil-borne diseases.

Harvesting Your Potato Plant
The time to harvest depends on the variety and your desired outcome. “New” potatoes, which are small and tender, can be harvested about two to three weeks after the plants begin to flower. For mature, storage-quality potatoes, wait until the foliage has died back completely, usually in late summer or early fall. Carefully dig around the base of the plant with a garden fork or trowel, being careful not to damage the tubers.
Harvesting should be done on a dry day to allow the potatoes to cure. Once harvested, gently brush off excess soil (avoid washing them) and let them cure in a dark, well-ventilated, and humid area for about two weeks. This curing process helps to heal any minor cuts or bruises and toughens the skins, improving their storability.
Potatoes are the fourth-largest food crop in the world, after rice, wheat, and maize.
FAQ Section
Q1: How long does it take for a potato plant to grow?
A1: The time it takes for a potato plant to grow varies by variety, but generally, you can expect to harvest new potatoes in about 7-8 weeks and mature potatoes in 90-120 days from planting.
Q2: Can I grow potatoes in containers?
A2: Yes, absolutely! Potatoes grow very well in containers, grow bags, or even large buckets. Ensure the container is deep enough (at least 12 inches) and has good drainage.
Q3: What are “eyes” on a potato?
A3: The “eyes” are actually buds on the potato tuber from which new shoots and roots will grow when the potato is planted.
Q4: Why are my potatoes turning green?
A4: Potatoes turn green when they are exposed to sunlight. This green part contains solanine, which is toxic. Always hill your plants sufficiently to cover the developing tubers and discard any green parts before eating.
Q5: How should I store harvested potatoes?
A5: Store harvested potatoes in a cool, dark, dry, and well-ventilated place. Avoid storing them in the refrigerator, as the cold temperatures can convert their starches to sugars, affecting their taste and texture.
