When To Start Growing Tomatoes In Greenhouse

If you’re doubtful on when to start growing tomatoes in a greenhouse, you can do it either in fall or early spring. This way, you can get a late yield or an initial yield depending on what you need. Another common practice is to plant in a two-crop rotation where you sow for a fall crop and another one for a spring crop for an extended growing season. 

According to the University of California, you can get up to 20 pounds per plant in a spring crop from March to June. On the other hand, you’ll get half the amount of this yield in a fall crop from October to January. And since you’re using a greenhouse, you can plant tomatoes year-round without frost being a concern.

When To Start Growing Tomatoes In Greenhouse

Knowing When To Start Growing Tomatoes In Greenhouse

Fall, spring, or a two-crop rotation for an extended growing season are the ideal times for planting tomatoes in the greenhouse. However, it’s also essential to learn the season and temperatures and how to use an unheated greenhouse for growing tomatoes. This way, you can correctly plant your vegetables without the risk of any drawbacks. 

 

Seasons and temperatures

The ideal temperatures for growing tomatoes in a greenhouse are 70 to 80°F during the day and 60 to 65°F for the night time. Keeping this in mind, you must maintain the greenhouse’s recommended conditions when you plant either in fall, spring, or both. As mentioned previously, you can get up to 20 pounds of yield per tomato plant when you plant spring and then half of it for fall.

So if you’re using a greenhouse for commercial use, you can grow a spring crop from March to June or a fall crop from October to January as recommended by UC Davis. If you want to extend your growing season, you can also plant in a two-crop rotation. Sow seeds in early June or early July for a fall crop and seed in December to mid-January for a spring crop. 

However, it would be best to remember that tomatoes will only successfully grow and produce fruit if you meet their conditions. Therefore, always check the temperatures of the greenhouse accordingly. But what about the danger of frost?

During spring, where the frost has passed is a typical time to plant tomatoes in most areas. But if you’re in a state like Idaho with short growing seasons and high altitude, the University of Idaho Extension recommends another time for growing tomatoes. Plant the crops before the last frost date to help extend the growing season. 

 

Growing tomatoes in an unheated greenhouse

The temperature differences in a heated and unheated greenhouse have effects on the crops. With this in mind, you might be curious if you can still grow tomatoes in an unheated greenhouse if you live in a cold region. The good news is that an unheated greenhouse is still usable as long as you do careful planning. 

Since you can’t provide heat, you can only grow tomatoes in an unheated greenhouse after the last frost date has passed. This practice will put you ahead of your planting schedule, but you’ll also be extending your growing season. Some farmers recommend sowing six weeks indoors before the expected frost date so your seedlings will be healthy enough for transplanting. 

 

How To Grow Tomatoes Year-Round

The most significant advantage of growing tomatoes in a greenhouse is that it extends the growing season. Therefore, growing vegetables year-round is possible in a greenhouse given that you can provide the optimal conditions for the plants. Tomatoes will fruit best from the warmth of spring and summer, but controlling the climate and using proper cultivars will let you produce fruits throughout the year. 

The best trick for year-round growing of tomatoes is choosing cultivars that are suitable for the current conditions. You can start the growing season early by using cold-tolerant varieties and use other cultivars for the summer. Learn more about indeterminate and determinate types of tomatoes as well. 

The success of a year-round productive greenhouse will then depend on how you control the environment for the tomatoes. The Agricultural Extension Service of the University of Tennessee emphasizes controlling the greenhouse using heating, ventilation, and air distribution systems. Check the temperature, carbon dioxide, and humidity of the greenhouse year-round. 

 

Conclusion

The beauty of using a greenhouse is that it’s possible to extend the growing season and even have tomatoes year-round. But do you know when to start growing tomatoes in the greenhouse? You can have a two-crop rotation for fall and spring, but you can also grow either in fall or early spring. 

If you do a spring crop from March to June, you can yield up to 20 pounds per plant. On the contrary, a fall crop will yield 10 pounds per plant. And if you live in a short-season region, you can avoid the dangers of frost by planting tomatoes before the last frost date. 

Overall, using a greenhouse is an excellent way to have a productive tomato garden. However, the success relies on your ability and consistency of maintaining the ideal conditions for the plants. Know the proper timing and practices, and you shouldn’t feel intimidated by growing tomatoes in a greenhouse.

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.
