How To Prepare The Seeds Of Crops Before Planting In A Greenhouse

Before they produce fruits and veggies, each plant starts with the seed, and how to prepare the seeds of crops before planting in a greenhouse is a way to discover. 

Start by using your fresh seeds. If you have leftover seeds from the previous year, they may be tested for germination before proceeding. You can have a number of seeds, from as little as 10 to as much as 100 seeds on your paper towel, moistened.

Then, fold the paper over the seeds and place them inside the plastic bag in a warmer area. Take this paper out and inspect your seeds around twice per day, spraying them with water to keep moisture around the seeds. After a certain number of days required to germinate them, count to see how many seeds have grown, and compute the germination percentage. Without further ado, let’s get to the discussion.

How Do You Start A Greenhouse With Seeds?

Things You’ll Need

In order to get started, you will need to prepare the following: bowl, sterile seed-starting tray, vermiculite, potting soil, optional clear plastic bag, heating mat, spray bottle, optional heater, fan, fluorescent lighting, larger containers, and your all-purpose fertilizer.

The Procedures 

Start with filling flowerpots, seed-starting trays, and peat pots with your moist seed-starting mixture. Plant the seeds based on the directions on the seed packet, arranging these in two to three seeds from each container at depth with ½ inch at most. Then, cover your seeds with soil and use water to mist. 

After these, cover your pots or your trays with your plastic wrap. Place these in bright and warm locations, and you may manufacture with an electric heating mat for allowing the seed to regulate the soil temperature. As your seedlings appear, take away the plastic wrap.

Keep the planting mix moist, but avoid having them waterlogged. Then, snip the excess plant seedlings with your scissors, leaving a seedling from each pot. Allot one to two weeks for the fertilization process using the water-soluble fertilizer at a quarter strength 5-10-5. You have learned about these steps, too, in the other blog posts we have here. 

With ¼ of your fertilizer solution, water the seedling and water the plants after fertilizing. Once the seedlings are eight weeks old, they are ready to get planted outdoors and harden off, with the weather condition permitting. Otherwise, translate these into larger containers to let them grow. 

How Do You Prepare A Greenhouse For Planting?

Greenhouses are all-season homes for your plants and all-year-round structure that can cater to the needs of your crops. It is interesting to note that when it comes to preparing the greenhouse for planting anew in the upcoming year, the wintertime is the best season to reorganize the greenhouse, and this involves de-cluttering and other habits.

Adding Greenhouse Vents

Conquering insufficient ventilation is a challenge for many gardeners. You have to make sure there are sufficient openings to allow better air circulation, and this would include slatted vents and two roof vents right on top.

The Automatic Vent Openers

One of the essential gardening equipment to have is the automatic vent opener. This could be your ultimate life-saver during the warmer days, and if you forget to open vents for any reason, this will make sure the warm air can still escape, preventing plants from reaching the point of shriveling.

The Use Of Shade Netting

During the summer, it is excellent to protect your plants from the harsh sun, so you must ensure that you invest in shade netting to throw over each side of the greenhouse. You may also fit blinds indoors, but they can be pricey and may tend to get into your pots, as well as with your growing bags. Use the more affordable inexpensive shade paint that you can easily wash off. 

Installing Electricity

To install electricity in your greenhouse may involve the costs, but it will be worth it since it can open up to a lot of possibilities. It will let you have the right light source to work with at night, as you plug in heated mats or propagators. 

You can also run electric heaters during the evening with their thermostat feature, in which they utilize power whenever you need it. You can hire the electrician for the installation to avoid the mishaps. 

Generating Heat

The heat source can extend the season of growth and increase the range of plants you can grow. If you have the power supply, the heater with your automatic thermostat will do the work for your necessities. Try to keep the greenhouse frost-free in the winter, as you aim for the temperature of four degrees Celsius or more.

Storing Water

Greenhouse plants require more water than those grown outside the greenhouse. What you can do is to use a water butt connected to downpipes if you are used to having tap water or rainwater for the plants.

Clearing The Greenhouse

Prior to starting on growing and sowing, what you can do is to clear the greenhouse of old plant materials that may harbor diseases. It is a good idea to compost, before clearing the surfaces of shelves and staging with soapy, warm water.

How Do You Prepare Seeds Before Planting?

You don’t need to be a master gardener to wow your visitors with the plants or herbs that you own—preparing seeds before planting is easy and can be done even by farmers starting in the craft.

  • Place seeds within your seedpods into the paper bag, as you fold the top down. Be sure to shake the container thoroughly to remove seeds from their pod. Open this bag to select the seed pods. Throw them away, as you pour seeds onto a newspaper.


  • Then, get going by filling your bowl with cold water, bringing in seeds with the wet membrane, including pumpkin seeds or tomato. These seeds tend to feel slimy to your touch, so what you can do is to rub the seeds with the fingers to remove the membrane. Scoop out any seeds and lay them in your newspaper. 


  • Take in a piece of sandpaper into your glass jar and place this on the rough side facing the interior of the pot, as well as the paper against the sides. Then, place your seeds in a single variety within the jar and cover. Shake the jar well for seed scarification


  • Next, fill your bowl with water and place in seeds you are preparing to get planted into the water, making sure they are submerged. Allow the seeds to absorb moisture as they are soaked for two hours, before scooping them out for planting. Use different bowls for each of the seed varieties.


  • Dip your veggie seeds with your disinfecting solution after soaking to combat bacteria and fungus. Fill your tub with water and bleach, and place your seeds here, allowing them to soak for one to two minutes. Remove the seeds and lay them on the newspaper to dry.

How to prepare the seeds of crops before planting in a greenhouse may sound technical at first, but with the right strategies, you can be able to ace this.
