Green Brain Cactus Seeds Heat Rare Succulents

Mammillaria Elongata ‘Cristata’ is also colorfully named the brain cactus due to its convoluted and sinuous growth. One of the more bizarre pieces of Cristata information is how the shape occurs.

The form is a result of damage to the plant when it is young. The cells at the injury site go crazy and multiply at a far faster rate than normal. This causes the twisted nature of the pads.

Brain cactus is a common houseplant and in cultivation, this “damage” is manually manipulated to create the fan-like growth. The brain cactus is generally a small plant, only achieving 6 inches (15 cm.) in height. They are chubby little guys with waistband widths of 12 inches (30 cm.) across.

Growing plants from seed are not as hard as you might think You should only plant a seed as deep in the soil as the seed is wide.  When seeds are planted too deeply the tiny plants emerge and begin to grow but do not reach the surface before they run out of stored food. 

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.  To pasteurize soil, put it in a shallow heatproof pan, place it in the oven at 300 degrees F for 30 minutes

PLANTING:  Be sure that all containers to be used are clean.   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 longer. Once the spines are showing, raise the cover for ventilation during the day.  Do not allow the soil to dry out.  Do not swamp them in puddled water but do not let them dry out completely.
