We develop below some basic tips to get a beautiful garden and planting wonderful starting from seed germination.
the shell of the seed is well moistened and can speed up germination. This dip can be one night or more according to some varieties.
Due to the permeability of some seeds, they germinate only if the envelope has decayed sufficiently, which can take several months or even years. To avoid this you can get rapid germination by scarifying.
Scarification facilitates germination. It should incise the seed using sandpaper, a razor blade, a nail file, etc..
For large seeds: we must make a small incision to using a small knife in hand.
For small seeds: they must be rubbed together or place them in a container (bag, etc ...) with sand.
Finally some seeds with a very thick shell and waterproof, require scarification and wetting to allow germination. Here is the flow of this type of operation :
a) Pre-humidification to warm water soaking it up to a softening of the envelope.
b) Pour the boiling water over the seeds softened and let stand 24 hours.
c) Rub los seeds on sandpaper, except for the small seeds to avoid damaging them or crush them.
The only way to germinate seeds in the thick envelope is altering the envelope to allow the water to penetrate. After this operation, most seeds germinate within a few days in warm weather.
A seed that absorbs water will increase by several times its size.
Stratification is the operation which consists in subjecting the seed artificially, a period of cold, heat or humidity to trigger germination.
The seed is covered with a protection which prohibits germination. Cold, rain will gradually wear out the envelope to allow germination. Of course, depending on the species these envelopes are different and therefore require more or less time of exposure to obtain satisfaction.
a) cold stratification :
The ideal is to use a plastic container with lid, arrange a layer of two to three inches of damp sand, then the seeds and then again over a very thin layer of sand. Everything is put in the refrigerator for 15 days or months depending on the species. For this operation it is also possible to use a sealed plastic bag.
b) Stratification by steeping :
Seeds should be soaked in water for 2 or 3 days, then they are put in pot for germination.
Germination time :
There are several elements required for seed germination: first of all the temperature and the substrate used and finally the watering. Of course patience is also a factor to consider: it is important not to manipulate the seeds during germination to see if all goes well! This is the best way of getting nothing. Germination of a seed can be very fast for certain varieties, about three weeks, but can be extremely long for some other species that can last several months. Seed quality is of course not only to question: germination depends on all the tips listed in this document.
Containers that you plan to use must be sufficiently filled to allow the perfect development of the seedlings after germination you just made on the advice set out above.
The earth should be mixed evenly. A good watering is needed. You can also complete the container in a bath to be sure that the entire substrate is moist.
The non-germination of seeds is largely due to temperature. Indeed, tropical seeds such need an average temperature of 28 °. We must monitor the temperature of the place assigned to the germination of your seeds. In summer a semi can be placed on the outside of the wind, but for germination during the other seasons it must be done inside the home.
You can determine the average temperature by raising the maximum temperature during the day and températuve minimum observed during the night.
We must also determine a location for seed germination in the interior: near a heat source, but certainly not top, a refrigerator because of the heat generated by the back of the refrigerator.
It acts here of an important element: the ability to let the oxygen necessary for seed development, drainage to prevent rotting.
The watering during germination of a seed is very important: you have a compost moist but not soggy, which primarily generate immediate decay of the seed. Do not put water in the saucer. The ideal is what is called the "drench": it acts to place the container in a bath of warm water in the amount equal to the depth of the land contained in the container.Thus, the earth soak alone according to his need.
For germination do not use cold or too hot, and especially do not put fertilizer.
Good planting ...
