PLANTING YOUR SEEDS:
With a little patience and effort, you
should have no problem raising beautiful cactus from the seeds. Please remember that cacti seeds
will sprout over a period of time, so don't be disappointed when only a few first start to sprout.
The others will arrive given time. Usually most of the seeds will sprout between 3-10
Bottom heat will give faster results, but is not an absolute necessity. If you
can provide bottom heat, then by all means do so, if you cannot, then use shallow containers
that can be covered with glass or plastic. The containers should be large enough to allow for
2 inches of crushed gravel or sharp sand (aquarium sand will do fine, to facilitate drainage.
On top of the sand or gravel, you will need to place about 2 inches of sterilized
We recommend a mixture of 1 part sharp
sand and 1 part peat humus. it is very important that the soil is sterilized. Heating soil in an
oven at 200 degrees for 15 minutes is a good way to assure it is properly sterilized.
Soak the soil with water mixed with
fungicide (if you have it). This will prevent damping off later on. Allow excess water to drain
off. Press seeds lightly into soil and cover with about 1/8 inch of soil. Cover with glass or
plastic and place in warm location. Keep soil damp, but not wet. We suggest misting the surface
After the seeds have begun to sprout,
leave the glass or plastic in place for about two weeks. In the meantime make sure the container
does not receive direct sunlight as this may kill the plants. When the cover is removed, make sure
that the plants do not receive any strong drafts or sudden temperature changes. It will take a
couple of days for the seedlings to become hardy.
CARING FOR YOUR PLANTS:
Never use tap water or alkaline water.
Rainwater is best but tap water that has set in an open container for 2 days will be fine. This
allows for the chlorine additives that most municipal water systems use to evaporate from the
Cacti cannot tolerate high alkaline soil.
Check your soil for pH if you have problems with cacti .
Use fungicide mixed in with your water
often when watering. This will help prevent "damping off," a soil borne affliction that has killed
many a seedling.
Use very weak solutions of plant food when
feeding. Too much fertilize will distort your plants.
Never expose young seedlings to direct
sunlight. They need bright, diffused sunlight.
The quickest way to kill a cacti is over
watering it. Let soil dry out before re-watering. Remember, these plants are natives to the
Cacti are susceptible to aphids, mealy
bugs, white flies and spider mites. Treat soil with systemic insecticides and add
paradichlorobenzene crystals to soil if possible. Organic gardeners my prefer to use natural
pesticides or predator bugs when necessary.
If a plant shows signs of rot due to over
watering, cut out the affected part immediately.
If the top of the plant is cut off, let
the dismembered piece air dry for a few days then repot. Often it will reroot itself.
Brown scarring is often a sign of too much
sunlight. Move plants to a more protected location.
If possible, let plants spend first winter
in original planter the seeds were sowed in. If overcrowding will not allow this, try to disturb
the roots as little as possible.
