Terete Vanda help
 

Attachment 138364Hi everyone I got some vandas that I need help with i attached a photo i plan to house it in some medium fir bark, coarse perlite, charcoal and some sphagnum moss. Is this potting mix okay? I really don’t want these to die so any help would be appreciated, also in the photo some of the leaves seem to be drying at the tips so I’m going to give a soak in water for a few minutes

They look fine.

Such critters need to be hot, in full sun, and watered like mad, so make sure your mix doesn't get soppy.

If you look in the photo with the single plant this one has some dying tips, I tried to give it more water but what would you recommend? I’m think it’s going to lose it leaves :(
I’ve also been watering with demineralized water is that alright?

How often do they get watered?

I just got it so I have no idea but I plan to water 2-3 days with this substrate

Get some significantly smaller pots. A plant the size of yours has no problems fitting in a 2" (5cm) x 2" (5 cm) x 2" (5 cm) pot.

Use only large grade bark. This is all you need.

They grow under bright indirect light.

Temperature should be 60 F - 90 F.

Moderate relative humidity is ok (50% - 75%).

The important part is that the roots get enough time to dry out a bit between waterings. They can tolerate being drier better than being grown too wet.

They are ridiculously slow growing, but moderately fast to die if conditions are not to their liking. I've had a Papilionanthe vanadarum for several years (I think 5 years if I'm not mistaken), and it still fits in the 2" pot I've had it in from the very start.

Does the size of the pot matter? And from the picture is the leaf suffering from lack of water?

Yes, it can. You need to balance gas exchange with water.

I don't see a big problem with desiccation. That will resolve itself if they are grown correctly.

Do not water these kinds of orchids too much or they will start dropping leaves like crazy, and when they do, they will be extremely difficult to recover.

It takes 1 year for 1 - 2 leaves to grow out to maturity.

The roots need to dry out completely between waterings.

I have occasionally been able to get away with watering Papilionanthe vandarum once or twice a week during times when I'm exhausted or too busy to keep up.

If you tend to be heavy on the waterings, switch to large grade bark with net pots.

All right I’ll buy a smaller pot. I just bought FEED ME! Low P-K Orchid Fertilizer and will water every 2-3 days

Be careful not to over-fertilize. Fertilize once every 2 weeks and you're good.
