Cactus

Sun: Bright, non-direct sun, 13 to 14 hours a day for germination, full sun once established.

Water: keep soil lightly moist during germination and for the first few months afterward.  Avoid humid conditions after germination.  Once the cacti have reached a few months, they can gradually be adjusted to drier conditions.

Soil: use a loam type, well-draining cactus soil with added sand or perlite, covering seeds lightly.

Temperature: 21 to 30 degrees Celsius (70 to 86 degrees Fahrenheit)

Germination Time: 1 week to 3 months

Growing cacti from seed can be rewarding, but requires a lot of patience as the seeds often take some time to germinate.  Once mature, cactus will bloom once a year under the proper conditions, producing some of the most colorful blooms.  Cactus are often thought to not require much water, however, with well-draining soil, they should receive plentiful amounts of water when they are watered.  The soil should be allowed to dry out completely between watering (do not allow seedlings to dry out).  The information provided here is generic and should only be relied upon as a general guideline.  If one has a specific species of cactus, it may be beneficial to look for germination instructions for that specific species.
