What Size Pot For Growing Spinach In A Greenhouse

If you’re not sure what size pot for growing spinach in a greenhouse is ideal, opt for a shallow and medium container. Spinach is an excellent green vegetable to grow in the greenhouse, and it’s also suitable for pots if you’re limited in indoor space. Because it doesn’t require an enormous container, you virtually have no excuse to skip the chance of harvesting fresh and healthy spinach in your backyard.

There’s no doubt that spinach is one of the healthiest foods, so why not cultivate this tasty green yourself? The greenhouse will provide and maintain the optimal growing requirements for spinach. And since you’re growing them in pots, maintenance will even be much more comfortable.

What Size Pot For Growing Spinach In A Greenhouse And Spacing Requirements

Spinach will thrive best in a shallow and medium container. To give you a general idea of the measurement, a pot 14 inches wide and 8 inches deep should be good for your spinach. These measurements will provide the ideal space for your seeds to grow. 

A container measuring 7.5 liters can hold three spinach plants, while a 38-liter container is suitable for ten plants. This means that if your pot is 14 inches in diameter, you can put up to 4 spinach plants. However, remember that if you’re growing many plants in a container or pot, you’ll eventually have to thin them 5 inches apart. 

Compared to other plants, it’s worth emphasizing the importance of the pot’s depth for spinach. This is because it has an extensive root system, and using a limiting container will cause problems in growth and overcrowding. Overall, remember to choose a pot 6 to 8 inches deep and plan if you want to grow many plants in a pot. 

 

Space requirements of spinach

After learning about the pot size for growing spinach in the greenhouse, you must also know its space requirements. You want to sow your seeds half an inch deep before covering them with soil lightly for starters. To ensure that they won’t dry up, add half an inch of mulch after sowing. 

The spacing of the seeds itself is also crucial for their growth because of their extensive root system. An inch of space between each seed should be enough. Once the plants grow at around 2 inches, you can trim them to keep them 4 inches apart

If you’re growing transplants, this space should be at around 8 inches. Ensuring proper spacing in the greenhouse will also make harvest easier. Each plant should have 3 inches of space, but this could raise to 5 inches if you harvest large leaves. 

On the other hand, a 2-inch space should be enough if you’re going to harvest early. Remember that wherever you’re growing spinach, consider their large leaves and root system. Still, spinach is one of those crops that will not require a vast area to develop, making them ideal for pot planting in the greenhouse. 

 

Caring For Spinach In Pots In The Greenhouse

 

Planting spinach

The best materials for growing spinach are non-porous, including glazed ceramic, concrete, or wood. Be diligent and practice cleanliness and sanitation to prevent contamination of the pots as well. As for the soil, the pH should be 6.0 to 7.0.

You can also create your potting soil using grit, vermiculite, and compost. Add some soy meal into the pot’s center before putting the potting mix at the top. You can also include other ingredients that will provide nutrients for your spinach plants. 

To encourage germination, ensure the temperatures between 35 to 75°F, and you can directly sow either in spring or fall. It can take 22 days to germinate but expect that spinach is relatively slow to establish. 

 

Spinach companion planting 

The greenhouse also makes an excellent place to do companion planting with spinach. By doing so, you can deter pests and attract beneficial insects. The plants suitable for spinach companion planting include parsley and annuals like petunias and marigolds. 

However, be aware of their spacing requirements so you can keep a neat-looking greenhouse. 

 

Feeding and watering

Spinach is a heavy feeder and requires consistent moisture. For feeding, choose a fertilizer that is high in nitrogen. You can feed the plants before planting, after thinning, and by side-dressing if they grow slowly. 

And like other plants, ensure that you water frequently, but be careful not to overwater the plants. 

 

Weeding

Spinach won’t grow successfully if it is competing with weeds. To address this problem, manual removal and mulching are a must. And to ensure proper spacing, remember to thin consistently. 

 

Conclusion

Growing in pots in the greenhouse is an excellent way to harvest fresh and healthy spinach even as a newbie gardener with limited space and time. But what size pot for growing spinach in a greenhouse is ideal? Use a shallow to medium pot measuring 14 inches wide and 8 inches deep. 

These measurements ensure that each plant will get enough space considering that spinach has an extensive root system. Spinach should also have 3 inches of space, but be sure to adjust accordingly, depending on when you want to harvest. Thinning once the plants grow will also maintain the space requirements for a good yield of this healthy green.

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.

 

Conclusion

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.
