Horticulture --- 001 Propagation

I got one of my hobbies, horticulture, back recently. :)
The reason was ..... hm.... I don't remember that now ^_^"
Anyway, the topic is Why do I usually choice the non-efficiency way, sowing, to get a plant?

ha~
The process of sowing and germination is so interesting, isn't it?
And I can get some self-satisfaction through it.
To increase the probability of germination,
there are some pre-treating methods need to be applied,
like cold/warm stratification for simulating natural winter/spring conditions that seeds must endure
before germination, and  to soak seeds in particular solutions(hydrogen peroxide, ...), ...
Sometimes, you may need to use some pesticides to suppress fungus, insects, ...

Oh, by the way,
since some of plants I like are not available in my country,
sowing is the only way to get these kinda plants.

Another reason is we can collect seeds form threes directly or ask some nice guys to
send you some seeds and all you need to do is send him/her a stamped addressed envelope (s.a.e.) and
a ziplock.
Yap, the former is free and the other just spend you 10 bucks (for stamps).
