Ornamental Coffee culture . . .
- Hello Janet (and maybe Roy, too),
I recently purchased a couple of 3" pots of Caffea arabica as an
ornamental from our local Home Depot here. I have moved both of them
up to 6" pots and they seem happy and are growing moderately well.
Each of the 3" pots contained approximately 3 seedlings (I don't
think these are tissue cultured) and a fourth popped up in one pot the
other day because I can see the seed coat, and the seed leaves have
A botanist here I know commented that coffee makes a better pot plant
for indoors than Ficus benjamina as Caffea doesn't throw off all its
leaves if it gets too wet -or too dry... or too hot, etc. He also
remarked that Caffea's main drawback would be its high sensitivity to
cold. (I'm thinking that they would be fine indoors during our six
weeks of potential cold in Florida.)
I guess my questions then are these:
1] How soon should they be moved up again? They are all about 7" tall
2] In pot culture what will be best to feed them? How about a timed
release fertilizer like NutriKote with minors? What formula?
3] Starting at what temperature F. should they be protected from the
4] As an ornamental in pots, should I separate them and place only
one plant per pot, or do they prefer (or maybe dislike) company?
5] How much -or little- light should they receive for best results?
Can they be used for an extended period indoors without much adverse
effect upon them?
6] Will they tend to be reluctant to bloom and set fruit under pot
cultivation (or indoors)?
7] What would you suggest the watering requirements would be under
pot culture? Are they very sensitive to the salts in 'city' water?
8] How large (and how soon) will the plants get, and how large a pot
should be provided based upon their height? Will keeping them in
smaller pots keep the plants small without any deleterious effects?
9] Will I be able to easily determine what cultivar (or hybrid) I
have as the plants get larger? There was no indication on the label
other than 'Caffea arabica'.
10] Would these plants be poisonous in any way to housepets, i.e.,
dogs or cats?
That's enough QQ for now, but I have not seen this asked here before.
[who couldn't think of anything else productive to ask tonight!]
