Some confusion on winter time and watering

[silken]

So it sounds like you have a Dendrobium of unknown species. Also a Cattleya hybrid which is the Slc. Miss Wonderful and two Phalaenopsis. One is the NOID Phal. and the other is the P. Sea Dreams "Bill's Choice x Dtps. Bill's Charisma

For Phals, I water them approx. every week, but as Leafmite mentions, that depends if they need it or not. I put a bamboo kebab skewer in most of my pots and leave them. Pull them out to see how wet they are to help determine if it's time to water. Then put them back into the same place in the pot. For Phals, I like the middle and bottom of the pot to get just dry or very close before a good watering. If you have clear pots you can see the roots. If they are green, they are still wet and if silvery colour, they are dry.

For the Cattleya, it will likely need more light than you are giving in order for it to thrive and bloom. They are fairly high light plants. They also like to be drier before being watered. I let mine get fairly dry before watering and have a good open airy mix of medium bark with lots of holes in the pot. I don't leave them dry for long tho.

For the Den, until you have an idea what it is, it's hard to say if it needs a dry cool winter rest or not. Some are quite warm growing and others won't bloom without that winter rest. If it bloomed on a spike from the top of the plant, it is likely a warmer growing one. You can Google different Dens and try and compare the bloom to yours.

Phals are fairly low light growers and prefer warmer temps. However in the fall, a few weeks of cooler temps often initiates a spike. If they are at room temps now, then sitting on a cooler windowsill or a cool room for a few weeks might help. When plants are kept cool, they shouldn't be too wet or root rot could occur.

Some Cattleyas do require a cool drier rest but most hybrids do fine in room temp but with good light such as overhead or an Eastern window.

I don't like to mist my plants as it can cause spots and bacterial infection if they don't dry quickly. Good moving air is essential for all the orchids.

I hope that helps.
