Fun Fact Many orchids will rebloom several times per year and can live for decades—the oldest plant on record thrived for more than years.

It is important to plant orchids in the appropriate potting medium which in the case of Moth orchids pahalenopsis is a pine bark based potting medium as the emulates the natural conditions of its native environment with really good drainage and allows humid air to circulate around the roots. This keeps the roots healthy and helps to mitigate a lot of the risk from overwatering due to the excellent drainage so that your orchid can flower.
Water orchids every 7- 10 days in the Spring and Summer when the orchid is more likely to flower and once every 10 days or so in Winter to keep the orchid healthy so that it can flower. Moss based potting mediums can work well for growing orchids only if you repot them regularly as they tend to decompose quicker then bark based mediums which causes them to hold onto more moisture and reduce the available oxygen around the roots. This then can cause root rot and result in a dying orchid read my article, why is my orchid dying?
If the orchid has been under any stress then it is likely to invest its energy into immediate survival of the adverse conditions and regrowth to replace any roots they may have died off, in which case it can take a year or so of favorable conditions for the orchid to start to display flowers again. Read my article, how to water orchids to learn how often you should water orchids in different seasons and in different conditions. Some orchids prefer a rest period in Winter when the temperature lowers and require less watering and no fertilizer in correlation to the lower levels of light.
This is because some species of orchid such as Dendrobium experience a cycle of temperatures throughout the year in their natural environment and when the orchid is exposed to more light and warmer temperatures in Spring it has all the resources and energy to innate flowering. Orchids of all species should be watered less often at about once every 10 days during Winter as levels of evaporation and vegetative growth are lower due to the shorter day lengths and avoid using any fertilizer during Winter.
When it is Spring increase the watering to watering around once every 7 days and use a specialized orchid fertilizer and the orchid should be able to display its more flowers.

The reason orchid flowers and flower buds fall off is because of a sudden change in temperature or humidity. Orchids flowers and buds fall off due to low humidity or if the temperature increases or The reason for your lilac dying is usually because the soil drains too slowly for the lilac to tolerate.
Lilacs require well draining soil, and if the soil is waterlogged around the roots this Skip to content. Reasons for orchids not flowering: Orchids require a cooler temperature at night to trigger flowering.
Not enough light to stimulate blooms. Flower spikes should be cut back to stimulate the new spikes and more flowers. A lack of fertilizer. Drought Stress and Low humidity prevent flowering. Overwatering and the wrong potting medium stresses orchids and prevents flowering. Orchids need a rest period in Winter to be able to flower. When it comes to orchid mixes, quality and freshness really matter.
Once you see for yourself the difference a fresh mix from the highest quality ingredients makes compared to store brands you won't ever want to go back to those inferior mixes again. Watching an orchid carefully can give clues to trouble at the root zone see clear pots. When we buy orchids at the store they are typically quite young. Over time each new leaf or pseudobulb should be bigger than the previous one or at least the same size.
This determination can typically be made when the next new leaf or pseudobulb begins to form, or the plant goes into its bloom cycle. There are two types of growth patterns for orchids, sympodial and monopodial. The monopodial orchids, Phalaenopsis and Vanda being the two most common, grow up off a single central stem with leaves on either side. We expect to see each leaf be at least as big as the leaf before it and hope to see at least one or two new leaves per year. The next bloom spike on a monopodial orchid comes from the base at the underside of a leaf, usually 2 or 3 leaves down from the newest leaf and on the opposite side as the prior bloom spike.
In order to keep blooming over the years, monopodial orchids such as Phalaenopsis need to put on new leaves each year. Over time, as the orchid grows in size and strength it will send out a bloom spike on each side of the stem simultaneously. Sympodial orchids have multiple growths and usually grow one or more new growths per year. Often the growth pattern looks like a corkscrew with each new growth coming from the side of the one before it in a circular pattern. For example, a young orchid which is purchased in bloom might have 4 or 5 stalks, most with leaves, with the bloom coming from the largest stalk.
These "stalks" are actually called "pseudobulbs". If the orchid does well we expect to see a new pseudobulb emerge from the base of the previous pseudobulb near where the orchid bloomed.
During the leaf and root growth period not the bloom period , usually in summer, this new pseudobulb will ideally grow to be at least as big or bigger than the one that just bloomed. The next bloom spike will come from this new pseudobulb. We are looking to grow the biggest, healthiest new pseudobulbs possible as they will be the source of the next season's bloom.
Ample light, food and sufficient water are keys to healthy new growth. Over time, as the orchid grows in size and strength it will grow multiple pseudobulbs which can all spike at the same time creating an abundance of flowers.
Each orchid type has a time of the year when it naturally will bloom. This may not be the same time of year that an orchid was blooming when it was purchased, as nurseries can force orchids to bloom off-cycle.
Plant labels can be very helpful in recording bloom cycles. Most orchids grow during the summer and bloom in the fall, winter or spring. Knowing the season that an orchid blooms helps alleviate the frustration of feeling like "It's July, why isn't my Phalaenopsis in bloom again now? For example, the Phalaenopsis orchid is most likely to grow new leaves in the summer and early fall and set a bloom spike in late fall. The spike will elongate during the winter with blooms emerging in late winter or early spring.
There are plenty of Phalaenopsis which bloom off cycle for a myriad of reasons from genetics to culture but most will follow this pattern. Many orchids bloom once per year, some twice or even more.
Once in bloom some flowers last weeks or months while others can last only days. Some basic research about the type of orchid will identify what to expect. For example, Phalaenopsis orchids usually bloom once per year and the blooms can last for months.
Once the flowers fall off it may have a couple of extra flowers emerge from the end of the bloom spike or branch of that spike and bloom again.
