Definitive Guide On How To Grow Kale In Greenhouse

Knowing how to grow kale in the greenhouse means learning where and when to grow kale, the optimal temperature for kale, watering and feeding kale, and harvesting kale. These four topics are straightforward to learn, but consistency throughout the process of growing kale indoors is necessary to yield a good harvest. Once you get used to these pieces of information, you can start adding freshly harvested kale in your daily meals and improve your health. 

 

Where and when to grow kale

For kale, you want to choose an area in the greenhouse that will give the greens 6 hours of direct sunlight to ensure a good yield. The soil you’ll use should also have a pH of 6 to 7.5 and is rich in nitrogen, phosphorus, and potassium. Depending on which you think will be more convenient for your greenhouse, you can either use seeds or transplants for starting kale in the greenhouse. 

The Michigan State University recommends sowing kale seeds in mid-June to August, while you can start the transplants in March to July for planting out in April to August. The germination can take up to 10 days, and transplants can take six weeks to grow. For the spacing, allocate one square foot per plant, and it’s also possible to do companion planting with alliums and herbs.  

 

The optimal temperature for kale

The optimal temperature for growing kale is cooler than most crops, and it can even tolerate frost as long as the greenhouse doesn’t exceed 75°F. Mature kale plants are one of the hardiest crops, so if you’re in the growing zones 2 to 8, you should not face any problems growing kale. Cornell University even mentioned that being “kissed” by frost improves the flavor of kale. 

This tolerance to cold conditions is also one reason you should sow and transplant 4 to 5 weeks before the last frost date. Depending on your plants, some can tolerate 10°F and maintain their leaves without continuing to grow. And since you’re using a greenhouse, you don’t have to reach this point of extreme temperatures, so your kale will thrive year-round.  

Do note that while kale grows amidst cold conditions, high summer temperatures will be detrimental. Make sure to monitor the greenhouse temperature in the summer. Otherwise, you run the risk of low-quality crops with a bitter flavor and reduced growth. 

 

Watering and feeding kale

Like most greens, you must water your plants diligently during the growing season. The right measurement is giving one to one and a half-inch of water per week. An inch below the soil surface should be moist, so be careful not to overwater the plants. 

These water requirements will decrease after the first frost. What about feeding kale in the greenhouse? Feeding with balanced fertilizer should be enough once a month throughout the growing season. 

The University of Minnesota also recommends adding compost in spring or fall to improve soil quality. 

 

When to harvest kale

You can harvest kale when the leaves are as big as a hand. Assuming that you’ll harvest during frost, remember to take leaves from the base first because those touching the ground will not be useful later on. Ignore the torn or yellow leaves and pick a fistful per harvest. 

Since kale is grown annually, you must avoid picking the top center of your plant. Otherwise, the plant will stop producing. You can also extend your harvest because the plant continues to grow until 20°F.

 

Conclusion

Kale is probably one of the most popular green leafy vegetables. And if you’re interested in learning how to grow kale in a greenhouse, you’ll be pleased that this crop is relatively easy to cultivate, mostly indoors where you have control over the conditions. Remember to study where and when to grow kale, what’s the optimal temperature for kale, watering and feeding kale, and when to harvest kale. 

These four areas should help you ensure a good and quality yield. Remember the kale requirements from soil quality and spacing, location, feeding and watering, and optimal temperatures. Since it is a frost-hardy crop, you shouldn’t face any drawbacks, even if you live in a cold region. 

Still, maintain the optimal temperatures for kale in the greenhouse to keep it growing and productive. While it is a biennial, most gardeners in all USDA plant hardiness zones grow kale as annuals. Overall, you should be the one planning your growing season that will be suitable for your area.

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.

 

Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.

 

What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.

 

What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.

 

Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.

 

West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.

 

Mexican Avocados

Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:

 

Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.

 

Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.

 

Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.

 

Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.

 

 

Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
