In the case of very small seeds, less than 1 millimeter, just by letting them fall on the substrate, it will be enough. To plant correctly, we will make sure that both the substrate and the seed are deposited on the seed. That is, if the seed is about 3 millimeters, will be placed on top of this, about 3 millimeters of substrate. The containers used must be sterilized or disinfected before sowing. We will wash them with a 10% chlorine solution, that is, 10 ml of chlorine in 90 ml of water.Īfter washing them with chlorine, rinse well with boiled water. We can also use seed starter or seed trays They have a transparent plastic cover and electrical resistance that allow to adjust the interior temperature, in colder times. We can go to the market and buy, in establishments to that effect, electric seedbeds, which come to be like mini greenhouses. In plastic or clay pots, at least 7 to 10 cm in diameter or rectangular hermetic. Glasses, tubs or plastic or glass jars, small containers and where the possible presence of fungi is easily controlled . It is recommended that the containers we use do not have a substrate layer greater than 4 to 6 cm thick. The basic materials can be, from plastic cups to seedlings of several meters in length. Cactus in nursery Planters or containers for planting.Īccording to our ability or ambition when making cactus seedbeds, as to flowerpots , we can do something from small and personalized, to something big and more professional. In any case, use the necessary safety systems, glasses, gloves, etc., given the toxicity of formaldehyde gases. This way we eliminate the possible presence of fungi. Closes it well and after 12 hours, it is spread and left to air dry for 3 days, in a well-ventilated place. Place the substrate in a plastic bag with the formaldehyde solution. If it is a question of sterilizing large quantities of substrate, up to about 60 kilos, we will use formaldehyde in 15% solution, these is about 150 ml of formaldehyde, per liter of water. It is also possible to sterilize them in a bain-marie, it will take about 40 minutes of cooking. You could even sterilize the mixture, putting it in the microwave for 12 minutes, depending on power and quantity or in the kitchen oven, about 2 hours at 200✬. It is a method well known and learned since childhood. This method gives us a greater speed of germination, but the roots can be damaged, being very fragile entangled in the cotton.īeware of handling germinated seeds. There is a method that we have not commented yet and that in this section does not fit at all, since it is sown, but not on substrate as such, but on dampened cotton. Other mixtures for cactus seedlings will also be adequate. We can also prepare 60% black peat, 20% coarse sand and 20% charcoal powder.
If we want identical plants, we will have to reproduce them using the cutting technique. This way we will have our plant, cloned. ConsiderationsĪn important consideration we must make is that when we multiply our plants by seed, we will have plants that will NOT be identical to their parents. The vegetative or asexual reproduction is that achieved by means of cuttings or shoots. The technique of sexual reproduction or by seed , is slower, but very grateful as we will see our new plants grow in quantity and in a small space. The reproduction of the cactus , sexual reproduction or by seeds, is the most natural form of propagation, being also inexpensive, simple and accessible to all cactus enthusiasts.
