How Long Does It Take For Cucumber Seeds To Germinate

The answer for how long does it take for cucumber seeds to germinate is 3 to 10 days. This is why these plants are one of the most productive crops to have. However, note that this short germination period is only achievable if the seeds are in their ideal conditions.

For example, if the area’s temperatures reach 60 to 70°F, the seeds may germinate longer. From a maximum of 10 days, it may take them two more weeks to germinate. With this crucial factor in mind, it’s not surprising that many gardeners grow cucumber in the greenhouse to ensure the optimal growing conditions for the fruits.

How Long Does It Take For Cucumber Seeds To Germinate: The One Factor That Influences It

It will be beneficial to know the significant factors that play a role in the speed of cucumber seed germination. Keeping them in mind, you can modify the environment to support the development of cucumber seedlings. 


3 to 10 days

According to Michigan State University, cucumber seeds will germinate at 3 to 10 days. However, the optimal temperature for them to grow is between 60 to 105°F. As one can expect, not meeting this temperature range will halt or even prevent germination. 


The importance of temperature for germination

Because of this, the best time to directly sow them is from late May to June. Aside from the temperature as a significant factor for germination, you might also want to check when you got the seeds. They can only be viable from 2 to 5 years, so mark them before storing them. 

Since temperature and other factors like humidity and air circulation all influence seed germination, it’s best to start cucumber seeds indoors. Otherwise, timing is crucial for direct sowing. The best time to sow is late April in Minnesota because the last frost date has passed on this date. The soil temperature is also around 70°F, which is ideal for seed survival. 


How to speed up cucumber seed germination

Warm soil is necessary for germination, but it’s possible to plant seeds in mid to late summer for fall harvest in some areas. In the greenhouse, you can sow anytime as long as you provide the ideal growing conditions. It will also be more accessible to check the temperatures and other germination factors indoors.

Additionally, did you know that inadequate growing conditions such as extreme temperatures and low moisture can cause the cucumbers to become bitter? Therefore, using a greenhouse is not only beneficial for growth but also for yielding quality cucumbers. 


Growing Cucumbers From Seeds

Growing cucumber from seeds is possible indoors and outdoors. In the greenhouse, you don’t have to worry about the danger of frost. Start the cucumbers 3 to 4 weeks before planting them out, but remember not to use plastic seed cells for easier transplanting later on. On the other hand, you can directly sow after the frost’s danger has passed outside, and when the soil is workable.

You can then transplant cucumbers for early yields against competitors. Have two to three seeds per container and then thin them to one plant per container. Once the seedlings develop two to four true leaves, you can transplant them 2 feet apart in rows that are 6 feet apart.

Remember to allocate 2 to 3 seeds at an inch deep for every 12 inches in a row for outdoor sowing. If your soil still needs to warm up, the University of Minnesota recommends using black plastic mulch to raise it to the ideal germination temperatures. Once they germinate, you can thin the seedlings, so only the strongest remain per 12-inch interval in a row. 

You can also train the cucumber vines to climb a trellis around four feet tall at this point of growth. This is excellent for spacing and utilizing the garden, while also getting perfectly straight cucumbers. However, since you’re not using a greenhouse, remember to use row covers to ensure the proper temperature and prevent pests on your crops. 


Common Problems When Growing Cucumbers From Seeds

Once you’ve maintained the ideal conditions for seed germination, growing cucumbers is straightforward. However, you can expect problems now and then throughout the process. For example, pests like spider mites and cucumber beetles, or diseases like downy mildew, powdery mildew, or bacterial wilt are common drawbacks in cucumber production. 

If the weather is rainy or cold, you might also notice low fruit sets since they affect pollination. Nonetheless, problems in growing crops are part of the experience, and you shouldn’t feel worried. Preventing pests and maintaining proper hygiene and cleaning will address these problems.

And most important of all, keep the growing conditions stable. 



Cucumbers are one of the most productive plants to cultivate. But if you’re thinking of starting them from seeds, how long does it take for cucumber seeds to germinate? The seeds can take 3 to 10 days to grow, but it’s crucial to maintain the temperatures at 60 to 105°F, or they’ll take more weeks to do so. 

This is why those who live in an area with a short growing season start the cucumber seeds indoors and then transplant them when the soil is workable. However, you can still sow directly outdoors but make sure that the danger of frost has passed. Afterward, maintain discipline and consistency in monitoring your cucumber seedlings, so common problems become easy to avoid.

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.
