Cyrtanthus obliquus

Cyrtanthus obliquus

 Germinating the seeds

 

 When to plant -- Plant your seeds when you receive them for the best results.

 If you have germinated seeds of other Cyrtanthus species before, you may use the same technique that worked for you.  The following has worked for me.

 Soak the seeds in a cup of plain water for 24 hours.  After soaking them, plant them in a fast-draining soil mix.  A typical mixture is 1 part sterilized potting soil to 1 part perlite.  An alternate mix is 1 part coir fiber to 1 part perlite or coarse sand, with some slow-release fertilizer added.  You may plant the seeds in separate pots, or all together in 1 pot (spaced 2 inches / 5 cm apart).  Use pots with drainage holes.  Fill a pot with the soil mix, water it until evenly moist, and place a seed on it's side in the soil.  Sprinkle some soil over it - just enough to barely cover the seed - then water the top soil layer lightly.

 Place the pots 4-6 inches (10-15 cm) from a fluorescent bulb, or the equivalent amount of light.  Keep them as close to 66-74 degrees F (19-24C) as possible during the day, and a little cooler at night.  Do not let the seeds get too warm.  I suggest placing a thermometer near the pots, since the temperature can vary in different parts of a room. 

 Do not allow the soil surface to dry out.  You may enclose the pots in a plastic dome or bag to maintain moisture - just keep it open a crack to allow some fresh air to circulate.  You may need to drip a few drops on the seeds each day to keep them moist.

 The seeds can begin sprouting in 2-4 weeks, and continue for another month.  Continue keeping the soil surface moist after they sprout.  Once they are 2 weeks old, you may allow the soil surface to dry out between waterings, but keep the rest of the soil evenly moist (but not soggy).

 Be careful about giving them direct sunlight the first month, since too much sun may burn them initially.

 Feed about every 2-3 months with a slow-release (pelleted or organic) fertilizer.  If your potting soil contains nutrients (check the package) your seedlings shouldn't need fertilizer the first month.

 If your pots are less than 5 inches (13 cm) tall, gently transplant them to deeper pots when they are 3-6 months old.  Keep them in this pot for the next 2 years.

Good luck with them!
