How To Grow Leafy Greens In My Greenhouse

If you ever thought of “how to grow leafy greens in my greenhouse?” you’ll be pleased to know that it only takes four sections to get started and successfully harvest them. Four questions composed of what, where, when, and how will get you covered, and you should be prepared to have your supply of healthy greens soon. More than a productive endeavor, who would want to miss out on fresh crops that can beat disease

Leafy greens are not only nutritious by protecting and strengthening our bodies against diseases. Sadly, it’s not always possible to get a fresh supply of them, so growing them yourself is a more definite approach to living a healthy lifestyle. You might also be surprised by the profit benefits that leafy greens can give you because of their high demand. 

How To Grow Leafy Greens In My Greenhouse: Here’s What You’ll Need To Know


What to grow?


Check your growing zone

The University of Massachusetts Amherst mentioned an extensive list of leafy greens that you can grow. When one says leafy greens, it can be overwhelming for the newbie farmer to determine which crops are best for his greenhouse. To cull your list of options, you can always choose leafy greens that will thrive in your state’s growing zone

This way, you’re less likely to face drawbacks in planting because your garden vegetables are hardy enough for your location’s conditions. It will also always be a productive garden because you can create a growing calendar based on these crops that match your hardiness zone. Still, you are already ahead with using a greenhouse since it makes it possible to adjust the temperatures and other factors indoors for optimal crop growth. 


Leafy greens for the greenhouse

You have your usual greens such as lettuce, cabbage, kale, spinach, and arugula to choose from. These vegetables’ demands are high from people looking into including them in their diet because of the tagline, miracle foods.

Spinach, Swiss chard, Collard greens, lettuce, and some cabbage varieties are hardy, and even kale benefits from “frost kiss” to improve its taste. However, just because you can consider them as winter vegetables doesn’t mean you can be less involved in growing them in cold weather. Check the temperature indoor regularly to prevent damage, bolting, or even slow growth.


When to grow?

After listing the leafy greens suitable for your greenhouse, the next step is planning before starting to grow them. Because of the varying conditions and seasons per region, it’s difficult to say a definite month when to start growing leafy greens. Instead, remember that you aim to plant enough crops early to harvest efficiently once the cold season begins. 

Using the greenhouse makes it possible to seed early before short days start, which will also slow the growth rate.  As you have more experience in growing greens in the greenhouse, you can develop your planting schedule with expected harvest dates. For example, you may plan to grow spinach in September and October to pick them through February and still be productive. 


Where to grow?

Depending on your greens’ greenhouse and space requirements, you can choose to plant them in containers or directly in the bed. You can start greens in open seed flats or nursery flats and then transfer them when they’re mature enough. But more than the container per se, what makes up the growing media is also crucial for success. 

You can use soil or soilless media such as peat moss, perlite, and vermiculite. If you opted to use soil, fertile and well-draining soil should support your crops’ growth. Additionally, dont forget to fumigate them to prevent diseases in the greenhouse. 


How to maintain the greenhouse for greens?

Every leafy green has its fertilizer and water requirements, so the information below should be your general guideline. Some greens may require less fertilizer and water, while some are heavy feeders and drinkers. Just remember to jot down your plant needs and avoid over- and under-fertilizing and watering. 

Over-fertilizing can lead to aphid infestation, while plants in an overwatered medium are prone to developing diseases. What about the maintenance of temperature and light in the greenhouse? Again, the optimal growing conditions of leafy greens vary, so you can plant those with similarities simultaneously to avoid drawbacks. 

Otherwise, invest in cooling and heating systems, humidity control, and ventilation to ensure continuous plant growth. Light may also be necessary because its decline can cause unsatisfactory flavor and development on the green. Learn when to use a growing light depending on your greens’ growth stage and put it at a recommended distance from the crops. 



It’s possible to have your own supply of healthy crops and possibly use them as an income source. One of the best vegetables to grow in the greenhouse is greens, so researching how to grow leafy greens in my greenhouse is probably worth investing time and effort to. After all, you only need to know what to grow, when to grow, where to grow, and how to maintain the greenhouse. 

Your main takeaway here is that each crop has requirements, but using a greenhouse already makes it more convenient for you to adjust if necessary. Proper planning and dedication should get your leafy greens ready on your plate or at the market.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
