When To Start Flower Seeds In A Greenhouse For Spring Planting

When to start flower seeds in a greenhouse for spring planting is inarguably a great question to answer. These are promising structures to get started with the flower seeds. 

The rule of thumb: first, plant the seeds based on the directions found on the seed packets, and specifically, it indicates that it is usually two or three seeds for each pot at ½ inches. Then, cover the seeds with your soil and mist with your water. Cover your pots or trays with the plastic wrap.

You may also place this in warm, bright locations and with the electric heating mat manufactured for seed beginning to allow the farmer to regulate the temperature of the soil. When the seedlings sprout, you may remove the plastic wrap. 

You may go on to keep the plant mix moist but never waterlogged. Snip your excess seedlings with scissors, and leave a seedling from each pot. Every one to two weeks, fertilize the seeds with a quarter strength water-soluble fertilizer, 5-10-5. You may water the seedling with ¼ cup of the fertilizer solution, and water after fertilizing. 

Once the seedlings are eight weeks old, you can harden off and plant outdoors, considering pleasant weather. Otherwise, transplant into larger containers so they can keep growing. 

When Should I Plant Seeds In My Greenhouse?

Here, we talk about a definite time. If you are starting to plant, meaning to say, transplanting into gardens outdoors during the spring season, for instance, you must start the seeds in the greenhouse a maximum of eight weeks before the last frost date expected in your location. For more results, seeds must be germinated in temperatures around 27 degrees Celsius. 

Night temperatures must not be lower than 55 degrees Fahrenheit. The greenhouse temperature must be monitored, and greenhouses are generally warm in the day, and when the sun is shining, but could also get colder during the night. Seedling heat maps may help offer your seeds with consistent warm soil temperatures. 

Take a good note of the greenhouse equipped with fans or opening windows, which may vent greenhouses that have become intensely hot. 

When Should I Start Flower Seeds?

When to start flower seeds in a greenhouse for spring planting involves when you should begin flower seeds. For flowers growing in the cold season, seeds must be sown directly into the ground within April. They do correctly with maintaining the cold weather and offering blooms late in the spring. Right at the end of April, warm-season flowers should be seeded outdoors, too. 

How Do You Start Seeds In A Small Greenhouse?

Here, we are zooming into the smaller greenhouse or the mini-greenhouse, and with this type of greenhouse, you can have full control over what you place on the table for you and the family. The flowers are essential, and having said this, they deserve your attention as they bring in the beauty and fragrance into your life. 

Greenhouses of these kinds have the right levels of draft ventilation if you open both ends of the greenhouse, creating the tunnel effect for you. These are the steps.

Filling in the greenhouse tray or pots

You may start filling the planting tray but be aware of the greenhouse design. It must have the sterile potting mix, as you fill the water tray with an inch of lukewarm water, setting the soil tray or pots within. Let the soil absorb the moisture for 30 minutes until the soil surface is moist, as you empty additional water from the plate. 

Sowing the seeds

The next step is about sowing the seeds within the soil mix. It must be a depth twice the seed’s width. Plant two seeds in each pot or cell, or scatter the seeds around one inch apart in rows set an inch apart in your flats and trays. You may also mist the surface for moisture. 

Setting the greenhouse

You may set the greenhouse cover above the tray, as you place the greenhouse in a place that gets the brighter, indirect sunlight at temperatures 75 degrees Fahrenheit at most. See how the cover retains moisture in the soil, so watering isn’t required until after the germination process. 

Then, prop the greenhouse open after the seeds start to sprout to let condensation dissipate. You may use your pencil or stick to hold one of the ends of its cover-up.

Watering the seedlings

This must be followed by watering the seedlings when the soil surface fades. Simply pour water onto the tray as the soil soaks moisture from below, and the seedling leaves do not turn wet. Finally, remove the greenhouse’s cover before the seedlings grow taller enough to reach the plastic.

What Month Is Best To Plant Flowers?

There is a common notion that planting in the greenhouse does not require you to consider the season because, well, the greenhouse can provide the ideal temperature. Some meticulous farmers and gardeners always want to follow the schedule of cultivation and harvesting from traditional gardening even with the greenhouse.

In North America, the best month to plant flowers, as well as shrubs, trees, and flowers, is during the dormant season. This means during the late fall up until early spring. While it is perfectly alright to plant anytime within the year, there will be maintenance efforts that you have to do should you decide to veer away from this situation. 

Fall is the perfect time for trees and shrubs since they can bulk up the root systems over the winter, allowing them to drink in more water. Many people can feel the spring is the best time to cultivate, but you have to conserve effort and time during the fall. 

What Temperature Will Kill Seeds?

With regards to knowing when to start flower seeds in a greenhouse for spring planting, does temperature kill seeds? The answer is a resounding yes.

Seeds may begin the die when temperatures are more than 108 degrees Fahrenheit, but require longer hours of exposure at lower temperatures. When it’s less than 140 degrees Fahrenheit, some species tend not to be affected by heating treatments


Spring planting offers a variety of highlights. Among the popular entities to grow include spring flowers and spring vegetables. If you missed planting one of the best products in the fall, bulbs, then you can have the spring season to get the plants going. They can blossom just in time for the summer.

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.
