How to grow a cactus
For successful crops need heat and light. If there are lamps for additional lighting and a greenhouse, then you can sow at any time of the year. If there is no such inventory, you need to wait for spring. Summer crops will require winter lighting and maintenance in the greenhouse, as they do not have time to get stronger. The natural terms of the development of cacti suggest planting in November-December.
Sowing cacti can be made in any dish that has a hole in the bottom for the flow of water. It can be both clay and plastic bowls and boxes. Before sowing, the soil and seeds should be decontaminated with magnetsovka solution, the seeds can additionally be held in hot water or "Epiné", "Zircon" to stimulate growth. Crops should be covered with glass or film.
Cactus seeds are usually very small. To lay them on the ground, you can use a toothpick or needle, a needle, a brush with stiff bristles. In order to distinguish where there is any kind of cacti planted, in a large common bowl, you can use plastic plates on which you pre-record the variety of seeds sown here.
Not every type of soil is suitable for sowing cacti.The ideal would be a mixture of sand, charcoal powder, peat and brick dust with leafy ground in equal proportions. If you manage to get white and very large quartz sand, cacti will thank for their rapid growth, if not, then the larger the sand, the better. The soil must be very porous and breathable, nutrient poor in order to stimulate the development of a good root system.
Sown seeds are moistened with a small fraction atomizer to avoid soil erosion. It is better to take hot boiled water: in the process of spraying it will become warm, as cacti like. Cold water in adult plants causes root rot, and the seeds stimulate it to delay germination until warmer times. Although cacti tolerate long lasting droughts, this is true only for adult specimens, the first 2-4 months overdrying of soil is unacceptable, as is the bay. After this period, watering is carried out as the top layer dries.
In order for the seeds to germinate, as well as for young seedlings, fresh air is a necessity. Therefore, crops should not be closed tightly, leaving holes for ventilation in the film or slightly moving the glass from the edge. The highest percentage of seedlings is observed in the first 2-3 weeks.But some species require more time - for example, prickly pear. It often happens that the seed shell cracks, but the cactus cannot get rid of it - in this situation, the shell needs to be carefully removed and, together with those dropped, removed from the ground, as they can attract mold and pests, starting to decompose. If the seedling turned out to be a root up, it is necessary to gently turn it in the correct position and lightly sprinkle the root with earth.
