Subject: Cattlleya culture

My name is Lucho and I'm from Peru

In my little collection I have some C. maximas and one C. luteola and one C.rex all from my country.

It it is possible can help me with some asspects about cattleya care:

1.-In Lima water is to much hard with carbonates How can I reduce this concentration? In the present I aam boiling and cool the water, but I do not obtain much. Help me.

2.- In lima the humidity is usually 95% , I know cattleyas love 70 -80% of humidity, I need reduce, how I can do it?

3.-I read this plant love some vitamin b1, in what concentration and frequency?

4.- In Lima in winter and in part of spring and autumn it's cloudy, in this situation is it necessary protect the plant from the midday light?

5.- Some people say me, put some sugar in the water, I read that cattleyas in some period of its development use the sugar of fungus, and certain culture media have sugar , in the mature plant is necessary?


How you can see, I have much doubts. I'm a precipitant in this exiting culture, and I like learn much to give my plant a comfortable place for it's life in my little greenhouse


I thanks your time and your attention , and please excuse my deficient English


My best regard


Your friend Luis

Hi Lucho

Thank you for your message and questions. Its quite a challenge to answer them satisfactorily

I will answer them as you asked them below. I hope the answers assist. If you are learning culture, study and adopt the basic culture
recommendations and find out all you can about the natural conditions the species in your collection experience in nature, and try and
replicate that as much as possible. The vitamin and sugar supplements may be applicable for specialist growers, but if you are starting out, ;learn the basic cultural requirements first before getting involved in such issues.

I wish you luck with your collection. If you can see the plants growing in nature you have a real advantage over people such as myself you can only see photographs and read about the conditions.

With kind regards

Phil

and one c.rex all from my country. > if is possible I can know if you can help me with some doubts about cattleya care:

If water quality is a problem, you would need quite expensive equiptment to correct the quality as there is no inexpensive method.. A far better and easier approach is to collect rainwater from a satisfactory area and if required store it for future use. If you only have a small colletcion you would not need a very large collection area, and pure rain
water is the best of all, as it is likely to be only very slightly contaminated even in the very worst of places.



2.- in Lima the humidity is usually 95% , I know > cattleyas love 70 -80% of humidity, I need reduce , how I can do it?
Again, it is possible to reduce, but it is probably not worth while. The humdity is high, but should not be a major limitation, especially if you can keep the air moving through the collection


3.-I read this plant love some vitamin b1, in what concentration and frequency?
Some research has been done on this issue, but I know of no-one who uses it in a collection. You would need to research further for accurate informatin, but I would not expect worthwhile results in a small collection


4.- In Lima in winter and in part of spring and autumn it's cloudy, in this situation is necessary protect the plant from the midday light?
During the autumn, winter and early spring, the plants require full light for optimum growth, no shading is required. On very sunny days you willl need to ensure there is some air ventilation available to avoid excessive heat builldup, but for most of the period this should not be a problem. Most orchids requjire cool bright dry winters and warm wet
shaded summers brom the summer monsoomal conditions most naturally experience, and your clulture should be adjusted to provide this.



5.- Some people say me, put some sugar in the water, I read that cattleyas in some period of its development
use the sugar of fungus, and certain culture media have sugar , in the mature plant is necessary?
Generall for mature plants proovide a satsisfactory fertilising regime and supplementary sugar feeding should not be required. If you have sick plants then you may receive some benefit, say a teaspoon per gallon of water should be adequate. I know of no general use of suger feeding being recommended.
