Why Choose Small Potatoes? The Benefits of a Compact Harvest

Growing small potatoes, often called “new potatoes” or “fingerlings,” offers a unique set of advantages that appeal to gardeners of all experience levels. It’s not just about fitting them into tight spaces; there are many other delightful benefits to explore.

First off, the sheer convenience is a game-changer. Imagine pulling up a handful of perfect, bite-sized potatoes ready for roasting, boiling, or adding to a fresh salad. No need for peeling if you don’t want to – just a quick wash, and they’re good to go!

Beyond convenience, there’s a wonderful flavor profile. These smaller spuds often boast a sweeter, creamier taste and a tender skin that larger, more mature potatoes sometimes lack. They cook faster, too, making them a fantastic choice for quick weeknight meals.

For those mindful of their environmental footprint, growing small potatoes is a remarkably sustainable how to grow small potatoes approach. They often have a shorter growing season, which can mean less water and fewer resources over time. Plus, keeping your garden compact naturally encourages eco-friendly practices.

Lastly, the satisfaction of growing your own food, especially something as fundamental and delicious as potatoes, is truly unparalleled. It connects you to your food source and provides a rewarding gardening experience.

Getting Started: Your Essential how to grow small potatoes Guide

Embarking on your potato-growing journey is exciting! The key to success begins long before you even put a seed potato in the ground. Thoughtful preparation makes all the difference, setting you up for a fantastic harvest.

Choosing the Right Varieties for Small Potatoes

Not all potatoes are created equal when it comes to size. While any potato can be harvested early to get a “new potato,” some varieties are naturally predisposed to staying smaller or producing abundant fingerlings.

When selecting your seed potatoes, look for varieties known for their compact growth or early maturity. Some excellent choices include:

  • ‘Yukon Gold’: A classic, buttery yellow potato that can be harvested early for small, tender spuds.
  • ‘Red Pontiac’: Produces lovely red-skinned potatoes with white flesh, great for new potatoes.
  • ‘French Fingerling’: As the name suggests, this variety is perfect for long, slender, small potatoes.
  • ‘Russian Banana’: Another fantastic fingerling type, known for its rich, nutty flavor.
  • ‘Adirondack Blue’ or ‘All Blue’: For something unique, these blue-fleshed varieties offer visual appeal and a great taste when harvested small.

Always purchase certified disease-free seed potatoes from a reputable garden supplier. Never use grocery store potatoes, as they may be treated with sprout inhibitors or carry diseases that could harm your garden.

Chitting Your Seed Potatoes: A Head Start

Chitting is a simple but effective technique that gives your potatoes a head start. It encourages strong, healthy sprouts before planting.

  1. About 2-4 weeks before your target planting date, place your seed potatoes in a single layer in an egg carton or shallow tray.
  2. Position them in a cool (around 50-60°F or 10-15°C), bright, indirect light location.
  3. You’ll soon see short, stubby, dark green or purple sprouts emerge. These are ideal for planting. Avoid long, pale, weak sprouts that occur in dark conditions.

This process helps the potatoes establish themselves quicker once in the soil, leading to an earlier harvest.

Soil Preparation: The Foundation of Your Harvest

Potatoes thrive in loose, well-draining soil that’s rich in organic matter. This is crucial for tuber development, as they need space to expand.

  • In-Ground Beds: Dig down at least 10-12 inches, incorporating plenty of compost, aged manure, or other organic amendments. Aim for a slightly acidic soil pH (5.0-6.0) if possible, though potatoes are fairly tolerant.
  • Containers/Grow Bags: Fill your containers with a high-quality potting mix blended with compost. Avoid heavy garden soil alone, as it can compact and hinder tuber growth.

Good drainage is paramount. Potatoes hate “wet feet,” which can lead to rot and disease. If your soil is heavy clay, amend it heavily with compost and perhaps some perlite or sand to improve drainage.

Planting & Care: how to grow small potatoes Best Practices for Success

Now for the exciting part – getting those chitted seed potatoes into the ground! Whether you’re planting in a traditional bed or using containers, following these how to grow small potatoes best practices will set you up for success.

When and Where to Plant

Potatoes are cool-season crops. Plant them in early spring, about 2-4 weeks before your last anticipated frost date, once the soil has warmed to at least 45°F (7°C). They need a spot that receives at least 6-8 hours of direct sunlight daily.

For containers, choose pots or grow bags that are at least 10-15 gallons in size for good production. Fabric grow bags are excellent as they promote air pruning of roots and prevent waterlogging.

The Planting Process

Here’s a step-by-step guide for planting your chitted seed potatoes:

  1. Cut Seed Potatoes (Optional): If your seed potatoes are large (larger than a chicken egg), you can cut them into pieces, ensuring each piece has at least 1-2 “eyes” (sprouts). Let the cut pieces “cure” for a day or two in a dry spot to form a protective callous, which helps prevent rot.
  2. Dig Trenches/Prepare Containers:
    • In-Ground: Dig trenches about 6-8 inches deep and 12-18 inches apart.
    • Containers: Add 4-6 inches of prepared soil mix to the bottom of your container.
  3. Place Seed Potatoes:
    • In-Ground: Place seed potato pieces, sprout-side up, about 10-12 inches apart in the trenches.
    • Containers: Place 2-3 seed potato pieces directly on the soil, evenly spaced.
  4. Cover: Gently cover the seed potatoes with 3-4 inches of soil.

Hilling: A Crucial Step for More Spuds

Hilling is arguably the most important technique for maximizing your potato harvest, especially when you’re aiming for small potatoes. This process involves mounding soil or compost around the growing plants.

As the potato plants grow to about 6-8 inches tall, gently mound more soil or compost around the stems, leaving only the top few inches of foliage exposed. Repeat this process every 2-3 weeks as the plants grow, until you have a significant mound around the base of the plant or the container is full.

Why hill? Potatoes form along the underground stem. By hilling, you create more stem length underground, encouraging the plant to produce more tubers. It also protects developing potatoes from sunlight, which can turn them green and bitter (and slightly toxic).

Watering and Fertilizing: Your how to grow small potatoes Care Guide

Consistent watering is vital for healthy potato development. Aim for about 1 inch of water per week, either from rain or irrigation. The soil should be consistently moist but never waterlogged.

  • Water deeply and regularly, especially during flowering and tuber formation. Inconsistent watering can lead to misshapen potatoes or scabbing.
  • Containers dry out faster, so check them daily, especially in warm weather.

Potatoes are moderate to heavy feeders. Incorporating plenty of organic matter at planting usually provides sufficient nutrients for a good start. If your soil is poor, a balanced organic fertilizer can be applied when plants are about 6 inches tall, and again when they start to flower. Avoid high-nitrogen fertilizers, as they encourage leafy growth at the expense of tubers.

Sustainable & Eco-Friendly how to grow small potatoes Techniques

Gardening is all about working with nature, and growing small potatoes offers fantastic opportunities to embrace sustainable and eco-friendly how to grow small potatoes practices. These methods not only benefit the environment but often lead to healthier plants and better harvests.

Composting and Mulching

Compost is a gardener’s gold! Incorporating homemade compost into your soil enriches it, improves drainage, and provides a slow release of nutrients. It’s a cornerstone of sustainable gardening.

Mulching is another powerful tool. Once your potato plants are established and you’ve completed your first hilling, apply a 2-4 inch layer of organic mulch (like straw, shredded leaves, or wood chips) around the base of the plants.

Mulch helps in several ways:

  • Retains soil moisture: Reducing the need for frequent watering.
  • Suppresses weeds: Lessening competition for nutrients and water.
  • Regulates soil temperature: Keeping roots cool in summer and warm in cooler periods.
  • Adds organic matter: Breaking down over time to feed the soil.

Companion Planting

Companion planting is a natural way to enhance plant health and deter pests without chemicals. For potatoes, consider planting:

  • Bush Beans: Can deter Colorado potato beetles.
  • Marigolds: Known to repel nematodes and other soil pests.
  • Nasturtiums: Act as a trap crop for aphids, drawing them away from your potatoes.
  • Horseradish: Said to increase potato disease resistance.

Avoid planting potatoes near sunflowers, tomatoes, or squash, as they can compete for nutrients or attract similar pests and diseases.

Troubleshooting: Common Problems with how to grow small potatoes & Solutions

Even the most experienced gardeners encounter challenges. Knowing how to identify and address common problems with how to grow small potatoes can save your harvest and keep your plants thriving.

Pest Management

The most notorious potato pest is the Colorado potato beetle. Both adults and larvae can quickly defoliate plants. Look for their distinctive yellow and black striped bodies and reddish-orange larvae.

  • Solution: Hand-picking is effective for small infestations. Drop them into a bucket of soapy water. For larger problems, consider organic insecticides like neem oil or Bacillus thuringiensis (Bt) specific for beetles. Companion planting also helps.

Aphids can also be an issue, sucking sap from leaves. They’re tiny, soft-bodied insects often found on the undersides of leaves.

  • Solution: Spray with a strong jet of water or use insecticidal soap. Encourage beneficial insects like ladybugs and lacewings.

Disease Prevention and Treatment

Potatoes are susceptible to several diseases, with blight being one of the most serious. Early blight and late blight are fungal diseases that cause brown spots on leaves, eventually leading to plant collapse.

  • Prevention:
    • Use certified disease-free seed potatoes.
    • Ensure good air circulation by spacing plants appropriately.
    • Avoid overhead watering; water at the base of the plant.
    • Practice crop rotation; don’t plant potatoes (or tomatoes, peppers, eggplant) in the same spot for at least 3-4 years.
    • Promptly remove and destroy any infected plant material.
  • Treatment: Fungicides (organic or conventional) can be used preventatively or at the first sign of disease, but prevention is always best.

Scab is a bacterial disease that causes rough, corky lesions on potato skins. It’s often worse in alkaline soils.

  • Prevention: Maintain slightly acidic soil pH (5.0-6.0) and keep soil consistently moist during tuber formation. Avoid adding fresh manure to potato beds.

Green Potatoes

If you see green patches on your potatoes, it means they’ve been exposed to sunlight. This green color indicates the presence of solanine, a natural toxin that can cause stomach upset if consumed in large quantities.

  • Solution: The best prevention is proper hilling! Always keep developing tubers covered with soil or mulch. If you find green potatoes, cut away all green parts before cooking, or compost them if the greening is extensive.

Harvesting Your Tiny Treasures: how to grow small potatoes Tips

The moment you’ve been waiting for! Harvesting your small potatoes is incredibly rewarding. Knowing when and how to do it ensures you get the best flavor and yield.

When to Harvest Small Potatoes

For true “new potatoes” or small, tender spuds, you’ll want to harvest them earlier than you would full-sized potatoes. This typically happens about 60-90 days after planting, or roughly 2-3 weeks after the plants have started flowering.

You don’t need to wait for the plant foliage to die back completely. In fact, for small potatoes, you often harvest while the plant is still green and vigorous. This is one of the best how to grow small potatoes tips you’ll receive!

A good sign is when the plants begin to flower. This indicates that tubers are forming underground. You can “rob” a plant by gently digging around the base with your hands or a small trowel to feel for developing potatoes. Take a few, then carefully re-cover the roots so the plant can continue to produce.

The Harvesting Process

When you’re ready for a larger harvest, choose a dry day. This helps prevent soil from clinging excessively to the potatoes and reduces the risk of fungal diseases.

  1. Gently loosen the soil around the base of the plant with a digging fork or spade, being careful not to pierce the tubers.
  2. Carefully lift the entire plant, shaking off excess soil to reveal your bounty.
  3. Dig around the loosened soil to find any remaining potatoes that may have detached.
  4. For container growing, simply tip the container onto a tarp or wheelbarrow and sift through the soil. This is often the easiest method for harvesting!

Curing and Storage

Unlike mature potatoes that need extensive curing for long-term storage, small potatoes are best enjoyed fresh. They have thinner skins and a higher moisture content, meaning they don’t store as well.

However, a brief “curing” can still be beneficial:

  • After harvesting, brush off any loose soil but do not wash them.
  • Lay them in a single layer in a cool, dark, well-ventilated area (like a garage or basement) for a few days to a week. This helps toughen their skins slightly and heal any minor scrapes.
  • Store them in a cool, dark, well-ventilated place (like a paper bag or basket) for a few weeks. Avoid refrigeration, as it can turn their starches to sugar, affecting flavor and texture.

Enjoy your small potatoes within a few weeks for the best flavor and texture!

Frequently Asked Questions About How to Grow Small Potatoes

Can I grow small potatoes from store-bought potatoes?

While technically possible, it’s not recommended. Store-bought potatoes are often treated with sprout inhibitors and may carry diseases that could harm your garden. Always use certified disease-free seed potatoes from a reputable supplier for the best results and to protect your soil.

How much space do I need to grow small potatoes?

Surprisingly little! Small potatoes are perfect for compact spaces. You can grow them in containers as small as 10-gallon grow bags or pots, or in a raised bed. Each plant generally needs about 1 square foot of space for good production, but you can plant them a bit closer for smaller yields.

What’s the difference between “new potatoes” and “small potatoes”?

The terms are often used interchangeably. “New potatoes” typically refer to any potato variety harvested early, while the skins are still thin and tender. “Small potatoes” can refer to new potatoes or specific varieties that naturally produce smaller tubers, such as fingerlings.

How often should I water my potato plants?

Consistency is key! Aim for about 1 inch of water per week, ensuring the soil remains consistently moist but not waterlogged. Water more frequently during hot, dry spells and when plants are flowering and forming tubers. Container-grown potatoes will likely need daily watering in warm weather.

Why are my potato leaves turning yellow?

Yellowing leaves can indicate several issues. It might be a natural part of the plant maturing, especially if it’s closer to harvest time. However, it can also signal nutrient deficiencies (often nitrogen), overwatering (leading to root rot), underwatering, or the presence of pests or diseases like blight. Check your soil moisture, look for pests, and ensure good drainage.
