  • Gardening Satisfaction: There’s immense pride in growing your own food, especially a staple like potatoes.
  • Early Harvest: Unlike maincrop varieties, new potatoes mature quickly, offering an early taste of summer.

Understanding “New” Potatoes: Quick vs. Maincrop

When we talk about “new potatoes,” we’re generally referring to any potato harvested while small and immature. They’re typically harvested early in the season, often before the plant has fully matured. This contrasts with “maincrop” potatoes, which are left to grow larger and develop thicker skins for storage.

While any variety can be harvested as a new potato, some early-season varieties are particularly well-suited for this purpose due to their rapid growth and excellent flavor when young. We’ll explore some of those soon!

Getting Started Right: Selecting and Preparing Your Seed Potatoes

The journey to a successful potato harvest begins long before you put anything in the ground. Choosing the right “seed potatoes” and preparing them properly are crucial first steps.

Choosing the Best Seed Potatoes

First things first: what exactly is a “seed potato”? It’s not a true seed, but rather a small potato (or a piece of one) specifically grown and certified for planting. Using certified seed potatoes is one of the best how to plant new potatoes tips I can give you.

  • Certified Seed Potatoes: Always buy certified seed potatoes from a reputable garden center or online supplier. These are guaranteed disease-free, which is vital for a healthy crop. Grocery store potatoes, while they may sprout, can carry diseases that will harm your garden.
  • Variety Selection: For new potatoes, look for “early” or “first early” varieties. Popular choices include ‘Yukon Gold’, ‘Red Norland’, ‘Irish Cobbler’, ”Dark Red Norland’, and ‘Kennebec’. These mature quickly, usually in 60-90 days.
  • Size Matters: Choose seed potatoes about the size of a chicken egg. Larger potatoes can be cut into pieces, each with at least two “eyes” (sprouts). Let cut pieces cure for a day or two in a warm, humid place to form a protective skin, preventing rot after planting.

The Art of Chitting: Pre-Sprouting for a Head Start

Chitting, or pre-sprouting, is a simple but effective technique that gives your potatoes a head start, leading to earlier and potentially larger yields. It’s one of those pro how to plant new potatoes tips that makes a real difference.

About 2-4 weeks before your anticipated planting date, place your seed potatoes in a cool (50-60°F / 10-15°C), bright, frost-free location. An egg carton or shallow tray works perfectly. The goal is to encourage short, stout, green sprouts, not long, white, leggy ones (which indicate too little light).

These strong sprouts will quickly establish once planted, accelerating growth and reducing the time to harvest. Don’t worry if you forget this step; potatoes will still grow, but chitting gives them an edge.

Prepping Your Patch: The Foundation for a Bountiful Harvest

Potatoes are relatively unfussy, but they absolutely thrive in the right conditions. Proper site and soil preparation are key how to plant new potatoes best practices that will set your crop up for success.

Ideal Location and Sunlight

Choose a spot in your garden that receives at least 6-8 hours of direct sunlight per day. Potatoes love sunshine! Good air circulation is also important to help prevent fungal diseases.

Avoid planting potatoes where other nightshades (tomatoes, peppers, eggplants) have grown recently (within the last 2-3 years) to minimize the risk of shared diseases.

Perfecting Your Soil

Potatoes prefer loose, well-draining, slightly acidic soil (pH 5.0-6.0). Heavy clay soils can impede tuber development and lead to rot. If your soil is heavy, amend it generously with organic matter.

Before planting, dig in plenty of compost, well-rotted manure, or other organic amendments. This improves drainage, adds nutrients, and creates a friable environment for tubers to expand. A good rule of thumb is to amend with a 2-4 inch layer of compost worked into the top 6-12 inches of soil.

Container Growing: An Alternative for Small Spaces

No large garden plot? No problem! Growing new potatoes in containers, grow bags, or even old tires is a fantastic option. This is a great how to plant new potatoes tip for urban gardeners or those with limited space.

Choose a container that’s at least 15-20 gallons in size (e.g., a 15-gallon grow bag or a half whiskey barrel). Ensure it has drainage holes. Fill the bottom 6-8 inches with a good quality potting mix enriched with compost, then follow the planting steps below.

Your Step-by-Step Guide: How to Plant New Potatoes for Success

Now for the fun part! Getting your seed potatoes into the ground is straightforward, but a few key techniques will ensure a healthy, productive crop. This is your essential how to plant new potatoes guide.

Timing is Everything: When to Plant

Potatoes are cool-season crops. Plant them in early spring, about 2-4 weeks before your last expected frost date, as soon as the soil can be worked and its temperature consistently reaches 45°F (7°C).

In many regions, this means late March or April. If you’re unsure, check with your local extension office for specific planting dates for your area.

Planting in Trenches or Hills

There are two primary methods for planting: trenches or individual holes/hills. Both work well, so choose what suits your garden layout.

Method 1: Trench Planting

  1. Dig a trench about 6-8 inches deep and 6 inches wide.
  2. Place your chitted seed potato pieces (cut side down, sprouts up) at the bottom of the trench, spacing them about 12 inches apart. If planting multiple rows, space rows 2-3 feet apart.
  3. Cover the seed potatoes with 3-4 inches of soil. Don’t fill the trench completely yet! This partial backfilling is important for hilling later.

Method 2: Individual Hills/Holes

  1. Dig individual holes about 6-8 inches deep.
  2. Place one seed potato piece in each hole, sprouts facing up.
  3. Cover with 3-4 inches of soil.
  4. Space individual planting spots about 12 inches apart in all directions.

Spacing Your Seed Potatoes

Proper spacing is crucial for good air circulation and allowing tubers enough room to grow. For new potatoes, aim for about 12 inches between seed potato pieces. If you’re growing in rows, give yourself 2-3 feet between rows to allow for hilling and easy access.

In containers, you can typically plant 1-2 seed potatoes in a 15-gallon container, depending on its width. Give them plenty of room to thrive.

Nurturing Your Crop: Essential Care for Robust Plants

Once planted, your new potatoes will need consistent care to flourish. This section covers the vital aspects of your how to plant new potatoes care guide.

Watering Wisdom

Potatoes need consistent moisture, especially during flowering and when tubers are forming. Aim for about 1-2 inches of water per week, either from rain or irrigation. Uneven watering can lead to misshapen tubers or growth cracks.

Water deeply and less frequently rather than shallowly and often. Avoid overhead watering late in the day, as wet foliage can encourage fungal diseases. Drip irrigation or soaker hoses are excellent choices.

The Critical Practice of Hilling

Hilling is arguably the most important care task for potatoes. As your potato plants grow, you’ll gradually draw soil up around their stems, forming a “hill.”

Why hill? Because potatoes form on underground stems (stolons) that grow from the main stem. If these tubers are exposed to sunlight, they turn green and produce solanine, a bitter, toxic compound. Hilling keeps them buried and protected.

Start hilling when your plants are about 6-8 inches tall. Draw loose soil up around the stems, leaving only the top 3-4 inches of foliage exposed. Repeat this process every 2-3 weeks, or whenever the plants grow another 6-8 inches, until the plants begin to flower or the soil mound is about 12-18 inches high.

Feeding Your Potatoes

Potatoes are heavy feeders. Incorporating plenty of organic matter at planting is a great start. If your soil isn’t rich, you might consider a balanced organic fertilizer (e.g., 5-10-10 or similar, low in nitrogen, higher in phosphorus and potassium) when plants are about 6 inches tall, and again when they start to flower.

Avoid excessive nitrogen, which can promote leafy growth at the expense of tuber development.

Pest and Disease Management

Even with the best care, you might encounter some unwelcome visitors. Being proactive is key to dealing with common problems with how to plant new potatoes.

  • Colorado Potato Beetle: These striped beetles and their reddish larvae can quickly defoliate plants. Handpick them off and drop them into a bucket of soapy water. Diatomaceous earth can also deter them.
  • Aphids: Small, soft-bodied insects that suck plant sap. A strong spray of water can dislodge them. Introduce beneficial insects like ladybugs.
  • Early Blight / Late Blight: Fungal diseases that cause spots on leaves. Ensure good air circulation, avoid overhead watering, and consider certified disease-resistant varieties. Remove and destroy infected foliage immediately.

Regularly inspect your plants for any signs of trouble. Early detection makes management much easier.

Sustainable & Eco-Friendly Potato Growing

At Greeny Gardener, we love practices that benefit both your garden and the planet. Incorporating sustainable and eco-friendly how to plant new potatoes methods is easy and effective.

Companion Planting for Natural Pest Control

Companion planting is a fantastic way to deter pests naturally. Marigolds, nasturtiums, and catnip can help repel potato beetles and other common potato pests. Planting beans nearby can also enrich the soil with nitrogen, benefiting your potatoes.

Organic Fertilizers and Soil Amendments

Stick to organic matter like compost, well-rotted manure, and cover crops to enrich your soil. These amendments improve soil structure and fertility without synthetic chemicals, creating a healthier ecosystem for your plants and the beneficial organisms in the soil. This is a core tenet of sustainable how to plant new potatoes.

Water Conservation Techniques

Mulching around your potato plants with straw or shredded leaves helps retain soil moisture, suppresses weeds, and keeps soil temperatures consistent. This reduces the need for frequent watering, saving water and your time. It’s a simple yet powerful way to make your potato patch more eco-friendly.

Troubleshooting: Common Problems with New Potatoes and How to Fix Them

Even seasoned gardeners face challenges. Knowing how to identify and address common problems with how to plant new potatoes will help you keep your crop healthy and productive.

Yellowing Leaves

Cause: Often a sign of nutrient deficiency (especially nitrogen), overwatering, or underwatering. It can also indicate disease.

Solution: Check soil moisture. If too wet, improve drainage. If too dry, water deeply. If nutrient deficiency is suspected, apply a balanced organic fertilizer. Rule out disease by checking for spots or lesions.

Scab or Blight

Cause: Scab is a bacterial disease causing rough, corky spots on tubers, often in alkaline soil. Blight (early or late) is a fungal disease causing dark spots on leaves and stems, thriving in humid conditions.

Solution: For scab, adjust soil pH to be more acidic (5.0-5.5) and ensure good soil moisture. For blight, focus on prevention: use certified disease-free seed, ensure good air circulation, avoid overhead watering, and remove infected plant material immediately. Some resistant varieties are available.

Pests like Potato Beetles

Cause: Colorado potato beetles and their larvae can quickly strip plants of their leaves.

Solution: Handpick beetles and larvae into a bucket of soapy water. Introduce beneficial insects (like ladybugs, which eat aphids, often found with beetles). Use row covers early in the season to prevent adults from laying eggs. Neem oil can also be effective against younger larvae.

Harvesting Your Delicious New Potatoes

The moment you’ve been waiting for! Harvesting new potatoes is incredibly satisfying. Here’s how to do it right.

When to Harvest

New potatoes are typically ready to harvest 60-90 days after planting, depending on the variety. You’ll know they’re ready when the plants start to flower, or shortly after. The foliage may still be green and lush.

You don’t need to wait for the plant to die back completely, as you would for storage potatoes. The joy of new potatoes is their immaturity and tender skin!

The Gentle Art of Digging

Harvesting new potatoes is a bit like a treasure hunt. Gently insert a digging fork or spade several inches away from the main stem of the plant. Carefully loosen the soil and lift the plant.

You can “rob” the plant by feeling around for small tubers without fully uprooting it, allowing smaller potatoes to continue growing. Or, you can harvest the entire plant. Be gentle to avoid bruising the delicate skins.

Storing Your Bounty

New potatoes have thin skins and don’t store as long as mature potatoes. They are best enjoyed fresh! Store them in a cool, dark, well-ventilated place for up to a week or two. Avoid washing them until just before use to prolong their freshness.

Frequently Asked Questions About Planting New Potatoes

Let’s answer some of the most common questions I hear about growing potatoes!

Can I plant grocery store potatoes?

While grocery store potatoes might sprout, it’s strongly discouraged. They are often treated with sprout inhibitors and, more importantly, can carry diseases that could infect your garden soil for years. Always use certified disease-free seed potatoes for the best results and to protect your garden.

How long does it take for new potatoes to grow?

New potatoes, especially “first early” varieties, typically mature in about 60-90 days from planting. You can usually start harvesting them around the time the plants begin to flower.

What’s the best way to prevent blight?

Prevention is key for blight. Use certified disease-free seed potatoes, choose resistant varieties if available, ensure good air circulation between plants, and avoid overhead watering, especially late in the day. Remove any infected plant material immediately to prevent spread.

How much space do I need to grow potatoes?
