Germinating seeds in paper towel

Germinating seeds in paper towel, the seedbed is a good system for optimizing the garden space and being able to anticipate sowing, making the seeds germinate on their own in a simple way and without any expense. Growing the seedlings in trays with earthen bread kept in shelter is convenient for many species, which will then be transplanted in the field with already a month of life.

However, it is not always advisable to germinate seeds directly in the jar, especially for those crops that have very small seeds. In fact, we can make a seed tray, with a simple plastic tray, in which to put the earth or the paper towel. Today we see just how to carry out the paper towel method, often used for tomatoes and chilies.

The great advantage of the Scottex method compared to traditional soil is that the seeds always remain in sight and you can know how germination is going without having to wait to see if the sprout comes out of the ground.

The plastic box to use

Germinating seeds in paper towel

To germinate seeds in the paper towel, you first need a transparent plastic box, which is the best environment for our small seedbed. The box must have a lid with some holes to circulate the air, without exaggerating in order to keep the optimum humidity and temperature inside. Many small holes are better than a few large ones.

The box should ideally be square or rectangular, this facilitates the arrangement of small rows of seeds. Excellent boxes are the transparent ones like Ikea or those of Haribo gummy candies.

Which blotting paper to use

There are different types of paper towels, the foresight is not to use one that is too thick and resistant. Otherwise, the rootlets get entangled making transplanting difficult.

Colored or patterned paper towels should also be avoided: to make organic horticulture, chemical compounds must be avoided. Any inks in the kitchen paper come into contact with our seeds that are going to germinate.

Germinating seeds in paper towel

To carry out the sowing, a dozen sheets must be used, cut according to the size of the seedbed box. The sheets of paper towels, moistened with a few drops of water, must cover the bottom of the container while lying flat.

The water to be used to wet the paper towel must be little but sufficient to soak all the sheets, the paper must be soaked and not soaked, so it must be wet by drop or by spraying. The water must be slightly calcareous and at room temperature. If stagnant water remains, it must be removed with another paper towel which will then be thrown away after use, stagnation facilitates the development of molds and fungi.

After putting the sheets of paper towels all that remains is to arrange our seeds, leaving them the necessary space for future growth. If the seeds are placed too close together it will be difficult to transplant because the rootlets will get stuck and moving them would risk damaging the newly born seedlings.

Where to keep the paper towel seedbed

Our paper towel germinator can be kept in warm areas of the house, perhaps near a radiator or other heat source. This system is excellent for varieties that want the heat to ripen, such as hot peppers: it allows you to put ready-made seedlings in the garden, thus lengthening the summer period and approaching more tropical climatic conditions.

You will need to find a heat source near which to place our Scottex Box, for example, you can use the upper part of a PC in the power supply area or the heat produced by a radiator. During the germination period, that is from sowing to the moment when the seedling emits the cotyledons, the predominant environmental factor is heat. Fast germination is generally obtained with temperatures around 28-30 degrees, which must remain stable 24 hours a day. lighting for photosynthesis. Therefore, there is no need for a large light exposure: the normal light of the environment will be enough to give birth to the plant, later on, once the buds are born and the leaves have developed, it will be transplanted into the ground and here we will have to worry about giving the seedlings the correct lighting.

For this reason, in this phase, no specific lamps or others is needed, which instead will be used to grow the plant in a seedbed, if we decide to keep indoor cultivation for a long period we should buy or build a suitable grow box. This can be useful for example if we are germinating tropical chili varieties early.

Condensation on the cap of the box is correct to form, it is a good indicator of the right presence of water in our germinator. If you see the condensation effect decreasing, you can understand that it is drying up and in order not to let the seed die, it is necessary to intervene by wetting the paper towel.

The germination phase

The humidity softens the rind of the seed and over time allows the sprout to come out. It may happen that the seedling is unable to break the seed shell and develops internally, also generating the two leaflets (cotyledons), the seedling in this case is destined to die if you do not try to free the sprout, a very delicate operation. The seed bath in chamomile tea reduces this problem considerably.

A small drawback of the Scottex Method is represented by the fact that the very thin roots tend to penetrate the texture of the paper so you will notice some resistance while trying to remove the seedling. Rather than ruining the roots, which are very important at this stage, it is better to cut out the piece of absorbent paper and transplant the seedling, roots, and paper altogether in the soil. Since the paper towel is biodegradable, it will disappear in a very short time, degrading as an organic substance.

Repacking the germinated seeds

The paper towel support allows the birth of the plant, but does not allow its growth: as soon as the plant emits the first two leaves it must be planted in the ground. It is therefore the cotyledons, namely those first two embryonic leaflets, the signal that it is time to move the seedlings to put them in the soil. This is called repatching.

The roots are very delicate and tend to get stuck in the paper towel: be careful not to damage the root system by transplanting. Generally, from germination, it is reported in a jar and not directly in the garden, the horticultural plants will be planted in the open field only when the stem is more developed.

The transplant of the vegetable seedling must take place in a jar full of very fine seeding soil (better sift it) and with a good content of peat, placing the seedling in a hole one or two cm deep (depending on the type of vegetables the measure varies slightly). It is then covered with a little soil and a drop of water is added. Now all that remains is to wait for the plant to grow strong and then put it in the garden bed and bring the fruits to maturity. You can check the right period on the calendar of transplants for the garden.

Some useful tips for pills:

  • Use a square box rather than a round one: it is easier to insert the paper towel without having to cut it too much.
  • Do not use colored or drawn sheets of blotting paper to prevent the ink from contaminating the seeds.
  • Check the temperature (the ideal temperature depends on the vegetable but is generally still hot, around 20 degrees).
  • Use seeds from the previous year, or in any case not too old.
  • Use low-calcareous water.
  • Treat the seeds with chamomile (see how to make a chamomile bath with seeds).
  • If possible, keep the seeds a little distant from each other (a centimeter is enough) to be able to move them without risking damaging the rootlets.
