Hello, Some of my orchidé are showing some kind of white marks on its leaves. It feels like glue and it is all over the leaves. How do I treat it? How do I stop the other orchidé from getting the same thing. thanks Selly
This appears to be Mealy Bug.
Probably the most popular home remedy against this group of pests is to swab and daub plants with a cotton swab or ball of cotton dipped in isopropyl (rubbing) alcohol. The common 70% isopropyl alcohol available is satisfactory. First remove all the visible insects, large and small. Then treat the affected area with alcohol. With Scale insects and mealybugs you will still need to repeat the alcohol treatment to remove the tiny yellowish spots which are the recently hatched crawlers. Pay particular attention to the folds, crotches, branch bases, midrib areas, and roots.

I have an orchids which has previously bloomed. I cut the stalk back and now have leaves with aerial roots growing on the stalk.Very excited as I usually don't have much luck with rebooting. What should I do with it?
Feed it some fertilizer once a month at half strength, and keep it in an area that receives more than 12 hours of light a day. This will encourage new leaves and shoots. When it has recovered from flowering, then you can move it to an area that Gets 12 hours of light or less per day. They are photoperiodic, and will only bloom when the days are shorter.
Hi, My beautiful orchid keeps growing buds and then they fall off before the flower :( I originally had it on bathroom windowsill (North facing), I then moved it into my dining room a month or so later that is also north facing. I think this is where I went wrong so I have now moved it back to my bathroom. How do I overcome this? Thanks, Lucie
This can be a complicated subject to diagnose, since it has so many conflicting answers. Unfortunately, you will have to provide the perfect environment for it to do as it should.

I have my orchid outside for the summer. At what nighttime temperature should I bring it in?
That largely depends on the type of orchid it is. Vanilla orchids can die below 55 degrees F. whereas common phalaenopsis have been known to survive 40's Here is an article for more information: http://staugorchidsociety.org/PDF/ColdToleranceofOrchidsbySueBottom.pdf
Why have some leaves on my orchid turned yellow!
This is most usually caused by a lack of fertilization. You can use specially made orchid fertilizers. Mix at half strength and feed once a week with your regular watering.

Do I trim back the stem once the flowers have fallen off?
Only trim off any brown or dead growth. That stem will flower again if you leave it. In fact, this saves the plant quite a bit of energy. They will be a little healthier if you leave them.
