Getting Started: Choosing & Chitting Your Seed Potatoes
The journey to a successful potato harvest begins with the right preparation. This crucial first step in our how to grow potatoes from potatoes guide sets the stage for healthy plants.
Selecting the Right Potato for Seed
Not just any sprouted potato will do. While you can grow from a regular grocery store potato, for the best results, you want to be mindful of a few things. Certified seed potatoes from a reputable supplier are always the safest bet as they are guaranteed disease-free. However, if you’re using a store-bought spud, here are some how to grow potatoes from potatoes tips:
- Choose organic potatoes if possible, as conventional ones are sometimes treated with sprout inhibitors.
- Look for firm, healthy potatoes without any signs of rot, mold, or disease.
- Avoid potatoes that are excessively green, as this indicates high solanine levels, which can be toxic.
If your chosen potato is large, you can cut it into smaller pieces. Each piece should be about 1.5 to 2 inches square and have at least one or two “eyes” (the sprouts). Allow the cut pieces to “cure” for a day or two in a dry, warm spot. This forms a protective layer, preventing rot once planted.
The Art of Chitting: Waking Up Your Potatoes
Chitting is simply the process of encouraging sprouts (chits) to form on your potatoes before planting. Think of it as giving your potato a head start! This is a simple yet vital step for robust growth.
To chit your potatoes:
- Place your whole or cut potato pieces in a single layer in an egg carton or shallow tray with the most “eyes” facing upwards.
- Put the tray in a cool (around 50-60°F or 10-15°C), bright spot, but out of direct sunlight. A cool windowsill, garage, or shed works perfectly.
- Within a few weeks, you’ll see short, sturdy, dark green or purple sprouts emerge. These are ideal. Avoid long, pale, spindly sprouts, which indicate too little light.
Chitting can take anywhere from 2 to 4 weeks. Once the chits are about ½ to 1 inch long, your potatoes are ready for planting!
Preparing Your Garden for a Potato Patch
The success of your potato crop hinges greatly on the environment you provide. Proper site and soil preparation are key components of how to grow potatoes from potatoes best practices.
Potatoes thrive in full sun, meaning at least 6-8 hours of direct sunlight per day. Choose a spot in your garden that receives ample light throughout the growing season.
Soil quality is paramount. Potatoes prefer loose, well-draining, and slightly acidic soil with a pH between 5.0 and 6.5. Heavy clay soils or compacted areas can hinder tuber development. Amend your soil generously with organic matter like compost or well-rotted manure. This improves drainage, aeration, and provides essential nutrients for your growing plants.
If you have limited garden space or heavy soil, consider growing potatoes in containers, grow bags, or even old tires. This is a fantastic way to practice sustainable how to grow potatoes from potatoes, as it allows you to control the soil environment completely. Just ensure your chosen container has good drainage holes.
Planting Your Chitted Potatoes: How to Grow Potatoes from Potatoes Best Practices
Once your potatoes are beautifully chitted and your garden bed is ready, it’s time for the exciting part: planting! Timing is everything here.
Planting time typically occurs in early spring, a few weeks before the last expected frost, once the soil has warmed to about 45°F (7°C). In warmer climates, you might even get a fall crop.
For planting in the ground:
- Dig trenches about 6-8 inches deep.
- Place your chitted potato pieces, cut-side down (if cut), with the sprouts pointing upwards, about 10-12 inches apart.
- If planting in rows, space rows 2-3 feet apart to allow for hilling and good air circulation.
- Gently cover the potato pieces with 3-4 inches of soil.
- Water lightly after planting.
For container planting:
- Fill the bottom of your container with about 6 inches of prepared soil.
- Place 1-2 chitted potato pieces (depending on container size) on top of the soil.
- Cover with another 4-6 inches of soil.
- As the plant grows, you’ll add more soil, a technique called hilling, which we’ll discuss next.
Remember to handle those delicate chits with care during planting to avoid breaking them off.
Ongoing Care: The How to Grow Potatoes from Potatoes Care Guide
Once planted, your potato plants need consistent attention to thrive. This comprehensive how to grow potatoes from potatoes care guide will ensure your plants are happy and productive.
Watering Wisely
Potatoes need consistent moisture, especially during flowering and when tubers are forming. Aim for about 1-2 inches of water per week, either from rainfall or irrigation. The key is deep, infrequent watering rather than shallow, frequent sprinkles.
Avoid overhead watering if possible, as wet foliage can encourage fungal diseases. Water at the base of the plant. Signs of insufficient water include wilting leaves; too much water can lead to rot, so ensure good drainage.
Hilling Up for Success
Hilling is arguably the most crucial ongoing care task for potatoes. As your potato plants grow to about 6-8 inches tall, you’ll start mounding soil or compost around the base of the stems, leaving only the top few inches of foliage exposed. Repeat this process every few weeks as the plants grow.
Why hill?
- It protects developing tubers from sunlight, which can turn them green and inedible (due to solanine).
- It encourages more tubers to form along the buried stem, significantly increasing your yield.
- It helps suppress weeds and conserves soil moisture.
Feeding Your Plants
Potatoes are moderate to heavy feeders. Beyond the initial soil amendments, they benefit from additional nutrients during their growth cycle. A balanced organic fertilizer, especially one higher in phosphorus and potassium, can be applied when plants are about 6 inches tall and again during flowering. 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 or issues. Addressing common problems with how to grow potatoes from potatoes proactively is key.
- Colorado Potato Beetles: These striped beetles and their reddish larvae can quickly defoliate plants. Hand-picking them off is effective for small infestations.
- Early and Late Blight: Fungal diseases that cause brown spots on leaves and stems. Ensure good air circulation, avoid overhead watering, and use resistant varieties if possible. Remove and destroy infected plant material immediately.
- Scab: Causes rough, corky spots on tubers. Often a sign of high soil pH; amending with compost can help.
Regular inspection of your plants will help you catch issues early. Embrace organic pest control methods and maintain good garden hygiene.
Harvesting Your Homegrown Spuds
The moment of truth! Harvesting is the rewarding culmination of your efforts. Knowing when and how to harvest will ensure you get the best yield and quality.
You can start harvesting “new potatoes” – small, tender, thin-skinned tubers – about 2-3 weeks after the plants begin to flower. Gently dig around the edges of the plant with your hands or a small trowel to retrieve some tubers, being careful not to disturb the main plant too much, allowing it to continue producing.
For a full harvest of mature potatoes, wait until the foliage begins to yellow and die back, usually 2-3 weeks after the plant has finished flowering. This indicates the plant has directed all its energy into developing the tubers. Ideally, let the foliage completely die down before harvesting.
When harvesting, choose a dry day. Loosen the soil around the plant with a garden fork, being careful not to pierce the tubers. Gently lift the plant and carefully dig through the soil to find all the hidden treasures. It’s often surprising how many potatoes one plant can produce!
After harvesting, allow the potatoes to “cure” for about two weeks in a cool, dark, well-ventilated area. This toughens their skins, heals any minor nicks, and improves their storage life. After curing, store them in a cool (40-50°F or 4-10°C), dark, and humid place, like a root cellar or unheated basement, away from apples, which can emit ethylene gas and cause premature sprouting.
Troubleshooting: Common Problems with How to Grow Potatoes from Potatoes
Even seasoned gardeners face challenges. Here are solutions to some common problems with how to grow potatoes from potatoes you might encounter:
Green Potatoes
If you find green spots on your harvested potatoes, it means they were exposed to sunlight. This green color indicates the presence of solanine, which is toxic in large quantities. Simply cut away any green parts before cooking. Prevent this by ensuring proper hilling throughout the growing season.
Small Yields
Are your potatoes disappointingly small or few in number? This could be due to several factors:
- Inadequate watering: Inconsistent moisture, especially during tuber formation, can stunt growth.
- Poor soil: Compacted or nutrient-deficient soil won’t support robust tuber development.
- Insufficient hilling: Not hilling enough reduces the potential for new tubers to form along the stem.
- Too much nitrogen: While nitrogen promotes leafy growth, too much can come at the expense of tubers.
Disease Identification
Beyond blight, watch for:
- Potato Scab: Rough, corky lesions on the skin. Often cosmetic, but can be prevented by maintaining slightly acidic soil.
- Verticillium Wilt: Yellowing and wilting of leaves, often on one side of the plant. Rotate crops to prevent build-up in the soil.
Pest Control
Besides the Colorado Potato Beetle, keep an eye out for:
- Aphids: Small, soft-bodied insects that cluster on new growth. Blast them off with water or use insecticidal soap.
- Slugs and Snails: Especially in damp conditions, they can chew holes in leaves and tubers. Use organic baits or traps.
Remember, prevention is always easier than cure. Good garden hygiene, proper spacing for air circulation, and healthy soil are your best defenses.
Frequently Asked Questions About How to Grow Potatoes from Potatoes
Here are some common questions I hear from fellow gardeners about growing potatoes from potatoes:
Can I use any potato to grow new potatoes?
While you can use any sprouted potato from your pantry, for the best results, it’s recommended to use organic, disease-free potatoes. Certified seed potatoes offer the highest guarantee against common potato diseases, leading to a healthier crop.
How long does it take to grow potatoes from potatoes?
From planting to harvest, most potato varieties take about 70-120 days. Early varieties mature in about 70-90 days, while main crop varieties can take 90-120 days or more. “New potatoes” can be harvested a few weeks after flowering begins.
What’s the best way to store harvested potatoes?
After harvesting, cure your potatoes for about two weeks in a cool, dark, well-ventilated area to toughen their skins. Then, store them in a cool (40-50°F or 4-10°C), dark, and humid place like a root cellar, basement, or unheated closet. Avoid storing them near onions or apples, as gases from these can encourage sprouting.
Why are my potato plants not producing many potatoes?
Low yields can stem from several issues: insufficient hilling (which encourages tuber formation), poor soil (compacted or lacking nutrients), inconsistent watering (especially during tuber development), too much nitrogen fertilizer (promotes leafy growth over tubers), or inadequate sunlight.
Can I grow potatoes in a small space or container?
Absolutely! Potatoes are excellent for container gardening. Large grow bags, barrels, or even sturdy trash cans with drainage holes work wonderfully. This method is perfect for small yards, patios, or for gardeners with less-than-ideal garden soil. Just ensure the container is large enough (at least 15-20 gallons per plant for a good yield) and you follow the hilling process.
