When Orchids Are In Flower, Should They Be Fertilized?

Orchids are plants that require nutrient-rich potting media, and they should be fertilized during their blooming period to provide the necessary nutrients for flower production. A balanced fertilizer is best used, and orchids should be fertilized every two weeks during their growing season. Most orchid species benefit from weekly fertilization during their growth periods, while dormant stages often follow blooming.

If your orchids show signs of growth and blooming, they are likely in need of fertilizer. Over-fertilization may result in poor health and lack of growth, such as yellowing or wilting leaves. To ensure robust growth and generous blooming, it is essential to adjust the grow conditions to suit your grow conditions.

Orchid care is crucial for their growth and blooming, as it provides them with necessary nutrients. Proper fertilization, light, temperature, and humidity promote growth and blooming throughout the orchid’s lifecycle. Choosing the right orchid fertilizer is essential for proper development and blooming. Fertilizing during the resting phase helps give the orchid extra nutrients for reblooming.

It is important to avoid fertilizing while the plant begins to flower, as it can blast the buds, especially if it is high nitrogen. Skipping fertilizer for a few months won’t harm the plant, but it is essential to fertilize when the plant begins to flower.

A general rule is to fertilize orchids every 2 weeks during peak growth (spring and summer) and once a month during dormancy (fall and winter). Watering once per week is recommended, but not fertilizing every fourth watering. Fertilizing while the orchid is in bloom can cause premature bloom loss, and fertilizing during dormancy helps store energy for the plant.

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.

Is it okay to fertilize orchids in bloom?

Fertilizing orchids is crucial during vegetative growth before flower buds appear, and can be withheld until the plant completes its next dormant cycle and begins its active growth cycle again. Experienced growers may use a “three weeks on, one week off” routine, fertilizing weakly for three weeks and taking a week off to flush out built-up salts. Orchids have slightly different fertilizing needs, with most alternating active growth periods, culminating in flower production, followed by a dormant period, corresponding to their native wet-dry season cycles.

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.

Do you feed orchids after flowering?

Post-bloom orchid care is similar to regular maintenance for any other plant. It involves watering the orchid when the potting material is dry, providing ample indirect light, and fertilizing it weakly with a high-quality urea-free fertilizer. Some orchids may go through a dormancy period, such as Dendrobium, Cymbidium, Catasetums, Clowesias, Habenaria, and their hybrids, during winter or when temperatures drop. Phalaenopsis and Lady slipper orchids may not experience this, but with time and loving care, they will bloom again. It’s a normal process and there’s no need to panic.

How often should you fertilize orchids?

To ensure optimal orchid growth, it is essential to provide fertilization every two weeks during the peak growth phase and once a month during the dormant period. The use of a diluted 30-10-10 fertilizer or orchid food is highly recommended for this purpose.

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.

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.

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.

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.
