What Is The Hardiness Zone In Greenhouse Growing

The first question you must ask before planting is, “what is the hardiness zone in greenhouse growing?”  because this refers to the climatic conditions of the area. Regardless if you’re growing exotic flowers or vegetables, knowing the hardiness zone of your location dictates the success of plant growth and survival. The relevance of the hardiness zone in greenhouse growing is it will tell you the adjustments you must do indoors.

Additionally, you can identify what to expect and create solutions to potential problems year-round. Remember that every crop and plant will thrive in a specific set of conditions, so monitoring and adjusting the greenhouse is mandatory. You will also have an easier time choosing species and cultivars based on their hardiness and the hardiness zone of your state.

What Is The Hardiness Zone In Greenhouse Growing And How To Use It

 

What is a hardiness zone?

A hardiness zone, growing zone, or planting zone will tell you the average annual extreme minimum temperature of your state or region. This is more useful for farmers and gardeners than the lowest temperature ever or what temperature might occur in the future. For easier identification of your hardiness zone, the United States Department of Agriculture created the USDA Plant Hardiness Zone Map that you can view by state, region, or nationally. 

Overall, you can also divide the USDA plant hardiness zone map into thirteen 10°F zones, which also have subzones of 5°F. North America has 13 hardiness zones that you can differentiate based on their temperature and climate. But how do you distinguish each zone?

From zones 1 to 13, zone 1 would have the coldest conditions, and zone 13 would have the hottest climate. You will notice a 10°F difference in each zone, which means zone 1 would be 10°F colder than zone 2. Using this information, you can choose the recommended plants for each zone, and each crop will have supported zones for successful growth. 

However, don’t be surprised to see that some plants can thrive in more than one hardiness zone. If you’re using a greenhouse, it’s also crucial to check other factors such as sudden temperature changes, sun exposure, moisture, frost, soil quality, the plants themselves, and management. Lastly, each zone will have a different microclimate that you will have to learn before greenhouse gardening. 

 

How to use a hardiness zone for greenhouse growing?

 

Choosing plants

Did you know that you can also use the hardiness zone to choose and operate a greenhouse? By understanding the usual conditions, you can adequately determine the site, glazing, size, and greenhouse materials. For instance, selecting and operating a greenhouse in USDA zone 4 is affected by how you can prepare for the winter season. 

 

Adjusting the greenhouse conditions

If you’re one zone from the recommended hardiness zone, you can use a greenhouse to adjust the conditions that your plants will want. This can mean improving the temperatures to mimic the optimal conditions for their growth. However, it’s important to emphasize the effect of other factors to guarantee plant survival. 

For example, the Southeast region is dominated by growing zones 6 to 10. However, this region is also prone to having soils with excessive clay. It’s not enough to choose recommended plants for your state, but you must also address the soil or research plants that will thrive in this type of soil. 

 

Choosing and operating the greenhouse

Did you know that you can also use the hardiness zone to choose and operate a greenhouse? By understanding the standard conditions, you can adequately determine the site, glazing, size, and greenhouse materials. For instance, selecting and operating a greenhouse in USDA zone 4 is affected by how you can prepare for the winter season. 

 

What Challenges To Expect On Each Hardiness Zone?

The cold conditions in zones 1 and 2 can be challenging for greenhouse growing. Zone 3 can also experience high winds, while zones 4 and 5 can have short growing seasons. Zone 6 is the rating for most of the US, and it can give you many growing options because it’s more forgiving.

Speaking of which, zone 7 also gives different plant options, while the hot summer and mild winter in zone 8 give you an extended planting season. If you are in zone 9, you can have year-round planting easily. As for zone 10, extreme heat can cause problems. 

Zones 11 to 13 are in Hawaii, Puerto Rico, and some parts of the continental US. Zone 11 can skip the problems of frost, while zone 12 and 13 experience the hottest conditions. 

 

Conclusion

Greenhouse gardening gives you the ability to grow most crops and plants without the limitations and setbacks of outdoor conditions. But before you start planting, you must know what the hardiness zone in greenhouse growing is. By definition, it is synonymous with the growing and planting zone that dictates the average annual extreme minimum temperature of your state or region.

Upon knowing this information, you can choose plants, adjust greenhouse conditions, and choose and operate the greenhouse successfully. However, you must not forget about the sudden temperature changes, sun exposure, moisture, frost, soil quality, the plants themselves, and management. These factors are separate from the hardiness zone and might be specific to your garden only.

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.
