The
Adventure Begins:
The key to
growing cactus from seeds is that unlike other plants, cactus seeds need direct
sunlight (or grow lights) to germinate, so you must place the seeds on top of
the soil, not under the soil.
My best advice
is as follows:
1 - Use Cactus
Soil. This comes with the Odd Pods package and can be purchased separately if
you have just purchases seeds.
2 - Sift the
soil into a number of small ~ 2 inch planters, eliminating any clumps with your
hand.
3 - Thoroughly
moisten the soil - but make sure that there is no standing water.
4 - Evenly
sprinkle 6 to 10 seeds on top of the Cactus Soil in each 2“ planter (don't
cover with soil)
5 - Place the
planters where they will receive maximum sunlight. You can also supplement this
with a grow light or even florescent lights.
6 - Your seeds
will sprout at different times but you should see seedlings within 5 to 7 days.
7- Once the
seedlings appear, use a spray bottle to mist the seedlings to keep them from
drying out.
8 - Remoisten
the soil every 3 to 4 days for the first few weeks to prevent it from drying
out.
9 - Once they
get bigger water them every 3-4 weeks as necessary.
In the
beginning you need to prevent the soil from completely drying out without over
watering. It's a delicate balance for the first few weeks. After that most
plants require watering once every 2-4 weeks (bigger plants once every 3 to 4
weeks). If mold starts to appear, reduce the moisture and water the plants with
a mixture of one capful of hydrogen peroxide to 7 ounces of water. This will
kill the mold but not the cactus.
The next bit of
advice is to start out with about 1/3 of the packet the first time. This way,
you can learn from your mistakes (if any) and try again once you’ve gotten the
feel of things without ordering more seeds. I have one client who managed to
grow ~ 70 cactus plants from one packet of seeds but she is an expert. Most
people will be lucky to end up with 20 to 30 plants. Personally, I used the
entire packet the first time and managed to get 6 plants, which promptly died
because I didn’t water them enough. My second attempt was much better until my
wife accidentally knocked the planter off the kitchen counter (I think it was an
accident, but I do have over 100 cacti in the house = )
By now, I’ve
probably made it sound over complicated and you’ve probably given up all hope.
But with ~150 seeds to play with, you don’t really need to be an expert,
especially if you split the packet into thirds and try to grow them at three separate
times.
The most important
advice is to just have fun with this! Watching the seedlings sprout and grow is
fun and even if you only end up with half a dozen plants it’ll be worth what
you paid for them! For even more fun, try using some imaginative planters. For
example, I found a Terra Cotta Chili / Salsa Bowl, which really wasn’t meant
for plants as they have no drainage holes. But if you’re careful to not over
water the plants, they work just fine. And if you DO over-water the plants, you
can soak up the excess water by carefully pressing down on the soil with a
wadded-up paper towel.
Garage sales
and flea markets are also great places for finding unusual planters and if kids
are involved, finding the right planter can turn into a treasure
hunt. With a little imagination, you can turn this into a fun
adventure that the kids will remember for a lifetime. Best of luck and happy
planting …
