Can You Grow Potatoes in a Greenhouse?

If you're an avid gardener, you may have considered the possibility of growing potatoes in a greenhouse. While it's certainly possible to grow these tubers indoors, there are some factors to consider before getting started.

What Are the Benefits of Growing Potatoes in a Greenhouse?

Growing potatoes in a greenhouse has several benefits that make it worth considering.

Extended Growing Season

Greenhouses enable gardeners to extend their growing season by providing protection from harsh weather conditions. By starting your potato plants earlier and maintaining consistent temperatures inside your greenhouse, you can increase yields and harvests.

Pest Control

Potatoes are susceptible to pests such as wireworms and Colorado potato beetles. However, when grown in greenhouses, they are less likely to be affected by these pests because greenhouses offer better pest control measures than outdoor gardens.

Higher Yield

Growing potatoes indoors allows for more control over environmental conditions such as humidity levels and temperature. This can lead to higher yields since the plants will have fewer obstacles impeding their growth potential.

What Do You Need To Know Before Growing Potatoes In A Greenhouse?

Before planting your first seedling or sprout into your indoor garden bed or container potting soil mix this season:

Space Requirements

Potatoes require adequate space for growth so ensure that there is enough room inside the greenhouse for them to spread out without crowding each other too much – depending on how many spuds per plant is expected!

In general 2-3 feet between rows (from North-to-South) should suffice while each hill requires at least one square foot of area within which its roots can comfortably establish themselves before stretching upwards towards sunlight filtering through nearby windows or roof vents above them.

Soil Quality

Potato plants need well-draining soil with ample organic matter content so take care when selecting compost mixes or creating custom blends specifically formulated for growing potatoes in containers or raised beds inside greenhouses.


Potatoes prefer cooler temperatures between 60-70°F (15-21°C) to grow best. Ensure that the greenhouse maintains these temperatures by using a thermometer and installing any necessary heating or cooling equipment.

Light Requirements

Potato plants require plenty of light to grow strong and healthy. Make sure your greenhouse receives enough sunlight throughout the day, supplementing with artificial lighting if necessary.

Comparing Greenhouse vs Outdoor Potato Growing

While both indoor and outdoor potato growing have their advantages, here are some key differences to consider:

Space Constraints

Outdoor gardens may not provide adequate space for large-scale potato cultivation while greenhouses offer ample room for growth without taking up too much outdoor yard space.

Pest Control

Greenhouses offer better pest control measures than outdoor gardens, which can help prevent damage from pests like wireworms and Colorado potato beetles.

Environmental Control

Greenhouse growers have more control over environmental conditions such as temperature, humidity levels, and light exposure compared to those who grow potatoes outdoors. This allows for greater precision when cultivating crops indoors year-round.

Tips For Growing Potatoes In A Greenhouse

Here are some tips on how you can improve your chances of success when growing potatoes indoors:

  1. Plant seedlings or sprouts in well-draining soil with ample organic matter content.
  2. Maintain consistent temperatures within the range of 60-70°F (15-21°C).
  3. Ensure proper ventilation so that excess moisture doesn't accumulate around the plants' roots.
  4. Use stakes or trellises to support the plants as they grow taller.
  5. Provide plenty of light either through natural sunlight filtering through windows/roof vents above them OR using artificial lighting fixtures specifically designed for plant growth needs!

In conclusion, yes – you absolutely can grow potatoes in a greenhouse! With careful attention paid to factors such as space requirements, soil quality, temperature and light exposure, you can cultivate healthy potato plants indoors year-round. So why not give it a try for yourself?


Can you grow potatoes in a greenhouse?

Yes, absolutely! A greenhouse is an excellent place to grow crops like potatoes. In fact, growing potatoes in a greenhouse has become increasingly popular among gardeners because it provides an ideal environment for the tuberous vegetable to thrive. Greenhouses offer protection from extreme weather conditions and pests, making it easier for growers to cultivate healthier potato plants.

When growing potatoes in a greenhouse, choose early- or mid-season varieties that can mature within 80-110 days. Selecting smaller types of potato varieties like fingerling or new potatoes will also give you better yields since they require less space compared to larger varieties.

Potatoes do well when planted directly into the ground but can also be grown in containers if your greenhouse doesn't have soil beds. Containers can be filled with compost and organic matter such as straw or leaves for better drainage and root development. Remember that proper spacing between seedlings is critical; make sure they are at least six inches apart from one another.

What are the benefits of growing Potatoes in a Greenhouse?

Growing Potatoes inside your own backyard greenhouse comes with numerous benefits:

  1. Protection: The primary benefit of using a controlled environment provided by greenhouses is protection against natural elements such as intense sunlight radiation, strong winds & heavy rainfall which could significantly impact plant growth.
  2. Prolonged Growing Season: With greenhouses providing ample heat retention properties even after sunset/night time hours there's little-to-no limit on how long-growing seasons last.
  3. Pest Control: Being able to control what enters & exits through open windows/doors means no pesky insects will nibble away at precious tuber crops.
  4. Increased Yield Potential: Controlling nutrient levels means you have complete control over how healthy plants get which ultimately result in boosted productivity later on down the line!

What kind of soil do I need when planting Potatoes inside my Greenhouse?

Soil for growing potatoes in a greenhouse should be fertile, well-drained and moist. Sandy loam soil is ideal for planting since it contains the right amount of nutrients and has good drainage properties which prevents water-clogging around the roots.

If your greenhouse doesn't have soil beds, containers can be used instead. Make sure to use high-quality potting soil that's rich in organic matter like compost or peat moss. Mix one part sand with two parts potting mix to improve drainage.

It's essential to maintain proper pH levels of 5-6 when cultivating potatoes since they prefer slightly acidic soils. You can add lime or sulfur powder if necessary depending on your specific garden conditions.

How do I plant Potatoes inside my Greenhouse?

To grow potatoes inside a greenhouse, start by preparing seed tubers about two weeks before planting them into the ground or containers:

  1. Cut each seed potato into small chunks (around 2 inches) ensuring there are at least two eyes per chunk.
  2. Let them sit at room temperature for about a week until they form calluses on cut surfaces.
  3. Prepare garden beds by loosening up soil & removing any unwanted debris such as stones or rocks
  4. Using either trenches within garden bed rows/containers dig holes approx six inches deep spaced approx six-eight inches apart from one another
  5. Place potato chunks with eye visable side facing upwards within these newly dug holes then cover loosely with dirt

Make sure not to overwater freshly planted seeds since this could cause rotting issues down the line!

How long does it take Potatoes to grow in Greenhouses?

Potatoes typically take between 80-110 days from planting time until harvest day depending on various factors such as variety type planted & environmental conditions provided during cultivation period.

When grown indoors using greenhouses, yields can usually be expected much earlier than traditional outdoor methods thus allowing growers greater control over when they're able to harvest crops. With proper attention paid towards watering and soil amendments, you can expect an excellent harvest when planting potatoes indoors.
