If An Orchid Blooms, Do They Require Fertilizer?

Orchids are naturally low in nutrients, making them a good source of supplementation for their internal processes. However, they do better on a weak solution applied regularly, and fertilizing them with a balanced fertilizer is essential for their growth and blooming. Over-fertilizing orchids can lead to dry leaf tips and burned root tips. Proper fertilization helps develop a strong root system, healthy foliage, and gorgeous flowers.

A 20-10-20 orchid fertilizer is recommended for optimal health, as it provides specific nutrients such as Nitrogen, Phosphorus, Potassium, and trace elements. When an orchid is in the growing season, it is recommended to switch to a custom fertilizer. Orchids may induce flowering or other growth when an influx of nutrients occurs, as a sudden spike in nutrition is a sign of spring or the beginning of the rainy season.

Experts recommend fertilizing Phalaenopsis orchids once every other week or at least once a month after their blooms have dropped. Fertilizing while the orchid is in bloom can cause premature bloom loss, but during dormancy, the fertilizer helps store energy for a new stem and blooms. It is important to stop fertilizing when the plant starts its blooming phase, as it is crucial for their proper development and blooming.

To promote flowers, use a higher phosphorous fertilizer like 3-12-6. Once the orchid is prepared to bloom, it is necessary to return to a balanced fertilizer, such as 20-20-20, that includes all “necessary trace elements”. Regularly feeding orchids with a balanced fertilizer is essential for their overall health and growth.

What is the best fertilizer for flowering orchids?

The NYBG Senior Curator of Orchids recommends using a balanced fertilizer like 20-20-20 in powder form to provide all the primary nutrients needed for flowering plants. These nutrients are represented by NPK numbers, which are nitrogen, phosphorus, and potassium. Nitrogen aids in vigorous growth and dark green color, phosphorus promotes root development and flowering, and potassium is essential for overall hardiness and disease resistance.

Secondary and trace nutrients are also present. Some orchid growers use high-nitrogen fertilizers like 30-10-10 to grow more leaves before switching to a balanced formula. Remember to change over well before the spring bloom period.

Can orchids survive without fertilizer?

Orchids can grow and flower for extended periods without fertilizer, but better results are achieved with some level of feeding. Typically, plants are fertilized once a week during the summer and every two weeks during the fall and winter. Most experienced growers use no more than 1/2 the label-recommended strength of fertilizer. It is best to water the potting medium before fertilization to wet the medium.

Fertilizers should contain little or no urea, as soil organisms must convert nitrogen in urea to a form usable by plants. High-nitrogen fertilizers are no longer necessary for orchids grown in bark mixes.

Incorrect watering kills more orchids than any other mistake. Proper watering consists of quantity and frequency, and should be watered just as they dry out. Factors such as humidity, air movement, potting medium type and age, and light levels all play a role. To determine when a potted orchid is almost dry, the surface of the potting mix will appear dry, dry pots will feel lighter, clay pots will feel dry, and a wooden stake or skewer inserted into the potting mix will come out almost dry.

Why is my orchid growing lots of roots but no flowers?

Orchids require adequate light to produce flowers, and insufficient light is a common cause of failure to rebloom. Leaf color indicates the amount of light, with a grassy green color indicating sufficient light for blooming. Orchid DealWire offers free access to orchid vendors’ special promotions and exclusive savings, ensuring the plant receives the necessary amount of light for successful blooming.

When should you not feed orchids?

The most prevalent methodology for fertilizing orchids is the application of a diluted solution of 1/2 to 1/4 strength on a weekly basis. In the fourth week, it is advisable to refrain from the use of fertilizer and to flush the potting media in order to eliminate any salt accumulation. This practice helps to maintain healthy growth and prevents the need for frequent watering.

How do I make my orchid bloom bigger?

Orchids bloom in seasons, and the best way to ensure their orchids return to bloom after their first blossoms fall off is by taking proper care during their dormant non-blooming season. Each orchid species has a natural blooming season, with most species blooming once a year, lasting up to several months. To ensure optimal blooming conditions, take the following steps:

1. Delay repotting until after the orchid finishes blooming.
2. Trim dead spikes.
3. Provide sufficient humidity.
4. Reduce ambient temperatures slightly when night falls.

Blooming occurs when new leaves emerge during the summer months, followed by spikes and flower buds in autumn. The blooming period typically ends around the end of winter or early weeks of spring.

Once your orchid is living at home, it will naturally revert back to its natural blooming cycle. To ensure optimal blooming conditions, take the following steps:

1. Trim dead spikes.
2. Provide sufficient humidity.
3. Reduce ambient temperatures slightly when night falls.
4. Provide proper care for your orchid during its dormancy or non-blooming season.
5. Maintain a healthy environment for your orchid to re-bloom each year.

Do you fertilize orchids when they have buds?

When fertilizing your orchid, it’s important to wait until the orchid has recovered from stress or illness. Orchids require both macronutrients and micronutrients, with macronutrients being essential in larger quantities like nitrogen, phosphorus, and potassium, and micronutrients being trace elements like iron, manganese, and boron. Choose a complete fertilizer that contains both macro and micronutrients.

Organic fertilizers, made from natural sources like fish and seaweed, are more effective due to their lower concentrations of macro and micronutrients and their reliance on biological and chemical processes. Organic fertilizers are also more biologically and chemically stable than inorganic fertilizers. Ultimately, the right fertilizer for your orchid’s needs will depend on its health and growth.

How do I know if my orchid needs fertilizer?

Orchids require fertilization during vegetative growth for proper development and blooming. To meet their increasing requirement for new tissue growth, a fertiliser rich in basic building blocks (macronutrients) such as nitrogen, phosphorus, potassium, calcium, magnesium, and trace micronutrients like zinc, manganese, cobalt, boron, copper, iron, and molybdenum should be applied. Nitrogen promotes leaf and shoot growth, phosphorus promotes healthy root growth, bud spikes, and blooms, and potassium builds plant strength and resistance to pest attack.

Orchid fertilisers can be grouped into Chemical and Organic fertilisers. Chemical fertilisers are manufactured in an industrial process and are available in a chemically pure form, such as NPK 20:20:20 and solutions of Calcium Nitrate and Magnesium Sulphate (Cal-Mag) in a chelated form.

Should I fertilize my orchid when it’s blooming?

Orchids require regular feeding during their active growth seasons and slightly starved during their dormant periods. Some orchids grow constantly and should be fed lightly year-round. High-quality fertilizer and water are crucial for orchid growth. The quality of water matters more than the fertilizer brand. Tap water is not suitable for mixing fertilizer, and softened water may contain ionized sodium. Distilled water is the best choice, free of chlorine, fluoride, and minerals, while rainwater is a strong second choice.

How do I get my orchid to spike a new flower?

To obtain a new orchid flower spike, place the plant in a lower room temperature (55-65°F) at night or in a window away from a heater. This method works best in winter when homes and windows aren’t as warm. Wait for a month for the spike to grow, which will look like a root with a knobby end called a “mitten”. Once it starts spiking, return the orchid to its normal growing location with a moderate room temperature of 65-75°F and bright, indirect light.

Support the spike with a stake and a loose tie once it reaches about 5″. If no new spikes are produced after a couple of months, try moving the orchid to a different location. Continue watering and fertilizing the orchid, but don’t move it around to avoid twisted flowers and an arching effect. The Phalaenopsis can usually grow a new flower spike or two annually.

How do I make my orchids bloom constantly?

To make your Phalaenopsis orchid rebloom, start fertilizing it every other week with an all-balanced fertilizer, either labeled as “bloom booster” or specifically designed for orchids. Increase light, find a new spot, and provide extra love during dormancy. Dormancy allows the orchid to replace nutrients used during blooming, and nutrients and water remain stored in the leaves until needed again. Dormancy can last anywhere from 6-9 months, and each orchid may bloom on its own, so it’s important to provide extra care and support to help it rebloom. Remember, every orchid is unique, so it may need to bloom on its own.

Do you need to water an orchid more when it’s blooming?

To ensure proper hydration of orchids, it is recommended to through-water them until free drainage is achieved, as using ice cubes can lead to under-watering and stressed root systems. After repotting, it is advised to not water the media for at least 3 to 4 days to allow roots to callous over and prevent rotting. Standing water can promote bacterial growth and cause rot over time, so it is important to avoid leaving the pot submerged in water for extended periods.

Phragmipedium orchids, which benefit from semi-hydroponic pots, can benefit from semi-hydroponic style pots. Additionally, it is advised to avoid watering late in the day and directly into the crown of the plant, as these habits can lead to sitting water culturing bacterial and fungal pathogens on the plant’s leaves.
