I'm relatively new to growing orchids and I recently had my Phalaenopsis start and produce a flower spike for the first time since I bought it two years ago. I just noticed yesterday that there is another small flower spike on the opposite side leaf starting to grow. Does anyone know what causes a double spike like this?
A happy orchid!
Or a very happy orchid..........................AL
I have a Yukidian with 3 spikes...not unusual.
I'm glad I have a happy orchid! Especially since it has just kinda sat there only producing leaves, but not producing flowers for the past two years. I was particularly surprised, given the colder weather that all of a sudden it decided to give two spikes! I guess I was just wondering if there is anything that can be done to induce more spikes (i.e. can it be repeated by doing anything in particular).
Orchids and other plants do like a 15F or more temp difference between nite and day (nite cooler). It does help trigger blooming for some types.
Some orchids, especially phals, need a temperature drop to induce bloom. As far as inducing more spikes there is really nothing you can do. The plant decides if it is going to produce spikes and the number. All you can do is take care of it and give it what it needs to be healthy. I have had some very healthy phals that will skip a year or two and not bloom. I have large ones that will give me one spike while a smaller one will produce two, three or four. One of the reasons I enjoy growing orchids is due to them being such mysterious and intriguing plants.
I am glad I came across this page dealing with phals, my six plants are outside all the time and with great pride I have to announce that three of them have produced two spikes, and I intend to put up photos of them just as soon as the flowers open cause there will be a very beautiful show of flowers, and there is one in particular that I had to save last year and I had put up photos of the dying plant, (no roots and rot) that has a very long spike and beautiful flowers opening and I am very pleased with it, I want to think that mounting them have encouraged that type of growth, and a vigorous root system.
I expose my Phals to low night temps for several weeks every fall and they all spike.
Here on the Sun Coast we usually get a natural November cooling perfect for spikes--80 day, 55-60 nights. Mine all spike like clockwork at the same time. When I visit them in summer, some are blooming again, for some mysterious reason. I say mysterious because the temps at that time are 90 day, high 70s nights. Maybe some strains don't need quite as much of a differential, but it's surprising that they would respond in such high temps!
I think after reading several posts regarding night temps, I will be less protective about bringing everyone in when the temp goes below 60...or am I wrong?
