Hello, dear friends.

I have been growing orchids for a long time, but not with the necessity dedication. They have thrived a lot and given me wonderful flower for many years. But the last two months were terrible, and I don’t know why many of them hade gotten brown and dyed. Maybe the problema is quite an excess of water, but I really don’t know. Please take a look at the pics and give some tips I could use to solve this problem.











Thanks,

Marcos Alexandre

The surrounding are does look pretty moist, and the medium some of the plants are growing in looks too dense for these orchid types.
What are the other growing conditions like?

Most of them are in conditions similar to the one seen on the first picture. There are only two in a more dense growing media. They were bought this way and I didn’t changed it.

Have you ever changed it? That media does look far too dense. If you have had the plants shown for more than a couple of years without ever repotting, then the media has likely broken down to the point of being more like soil -- something that will kill most orchids quickly. If you are in a wet, humid climate, then you may need to change the media every 6 months and should use a very coarse media. A few of the plants are too far gone with a fungal rot.

Thanks for the tips, friends. I’ll take some time to repot them and change the media.

Hi, everybody.

I changed the pots and media, and divided the rhizome of the bigger one into tow parts.







Unfortunately the second part ended up with no roots at all. I and to fix it with a wire.







And these are the other two that were in bad conditions:











The sun is on them, but it’s for a very short time, because the space through witch the sun passes is vary narrow.




Thanks a lot. Any more tips?

Regards,

Marcos

I water my orchids once every 10 or so days except for my paphiopedilums. I water my paphs every 3 or 4 days. Fertilize them lightly everytime you water them for strong root growth and all around health. You want to make sure there is plenty of run off each time you water to avoid salt build up. I would change out their media every couple of years and always replant them immediately if bought from a store because most of the time theyre growing in long fiber sphagnum packed way too tight.

Any suggestion on fertilization? Here I have osmocote 15-00-12. And NPK 04-14-08.

And I also have these

I'd use the last one at 1/4 strength.
