how to plant
SOIL: A good potting mix, amended with ½ its volume of granite, perlite or pumice for drainage, makes a good mix for growing cacti from seed. It is important that the soil be as pest-free as possible. To pasteurize soil, put it in a shallow heatproof pan, place it in the oven at 300 degrees F for 30 minutes. Most commercial soils are at least pasteurized, if not sterilized. Check the label.
PLANTING: Be sure that all containers to be used are clean. The type of container is not important, but shallow ones are preferred. Water the soil thoroughly and let it drain completely before planting. Spread the seed evenly over the top of the soil. Cover the seed lightly with the mix or very fine sand. When planted, cover the container with any transparent lid. This will retain moisture and allow light to reach the seedlings.
GERMINATION: Cactus seeds need both light and warmth to germinate. A sunny window is a good location, but be careful the light is not too strong and therefore too hot. The moisture retained by the cover should be sufficient to germinate the seed. Most cactus seeds germinate within 3 weeks, but some take much longer – be patient. Once the spines are showing, raise the cover for ventilation during the day. Do not allow the soil to dry out. The amount of water will depend on how much light and heat the seedlings receive. Watch the seedlings carefully. Do not swamp them in puddled water but do not let them dry out completely.
REPOTTING: Seedlings are ready to transplant into larger containers when they are the size of marbles between 6 months to a year after germination. Be sure the soil mix is very well drained, and the container is no larger than twice the diameter of the plant. At this size, plants can be grown in clumps or groups of 6-8 per pot until they are about 1 inch across, then separated and individually repotted. Lift the small plants carefully from the growing mix, place in the new container, firm the soil around the roots, and water in.
It is usually best to let the young plants recover from transplanting in a shaded area. Even in cacti that naturally grow with full sun, seedlings will be tender to full sun until they are older. Acclimate a young plant to the sun gradually beginning when it is about 1 inch across. It is often easier to acclimate young plants to the sun in the winter, and provide some shade in the summer until they are about 3 inches across.
FERTILIZATION: Fertilize young seedlings monthly in the growing season, usually the warm season. Use a formulation specifically for cactus, or an all purpose soluble houseplant formula at ½ the recommended strength.
put seeds into the warm water, Heated soaking, after 4-6 hours, remove the seeds, the seeds germinate easily after soaking. The seeds into the soil (Note: need loose soil, breathable, good water holding capacity), each container can generally be 5 to 8 on demand. Depending on growth conditions after germination the seedlings remain relatively strong strain; after germination thinning, as appropriate, leaving 1 to 3 seedlings. After sowing, cover with plastic wrap to the top container (plastic film may also be convenient bags), fresh stab a few holes in the membrane permeability. The container in the sun, keep the temperature around 20 degrees. Most seeds can germinate after a week. After the seedlings after germination and other robust transplanted into the ground
