How to Get Orchids to Rebloom: Care Tips & Best Fertilizers

How Do I Get My Orchid to Rebloom?

Give It the Right Amount of Bright, Indirect Light

Orchids need at least 6 hours of bright, indirect light per day. 

Orchids need bright, indirect light for at least 6 hours per day. An east-facing windowsill is ideal. A south or west-facing window with a sheer curtain works well, too. Avoid placing them on a shelf in the middle of a room, in a north-facing window, or anywhere more than 3 feet from a natural light source.

The leaves tell you everything. Medium green means the light level is right. Dark green means not enough light. Yellowing with a reddish tinge means too much direct sun. Adjust accordingly, and give the plant at least 4 weeks in the new spot before expecting a response.

Water Correctly

Orchids grown in bark mix need water only when the top inch of the medium feels dry, and the roots inside the pot have faded from green to silvery-white. For most homes, that means watering every 7 to 10 days.

In winter, when indoor heating runs constantly, you may need to water slightly more often. In humid summer months, it should be less frequent. Always let the medium approach dryness between waterings rather than keeping it consistently moist.

Drop the Nighttime Temperature to 55–65°F

Phalaenopsis orchids need a temperature differential of 10–15°F between day and night for a period of 2 to 4 weeks to initiate a new flower spike. 

To create a nighttime temperature drop, move the orchid to a windowsill in autumn and place it in a cooler room at night (a spare bedroom, sunroom, or an enclosed porch that isn't heated). Open a nearby window slightly in fall evenings when outdoor temps drop into the 50s, and avoid placing orchids near heating vents, which maintain artificially warm air.

Once you see a new spike emerging, bring the plant back to its normal warm spot and keep conditions consistent from then on.

Fertilize at Quarter Strength Every 2–4 Weeks

Orchids are light feeders, but they are not zero feeders. Feed at one-quarter of the recommended dose on a consistent schedule rather than giving occasional heavy doses, which can burn the delicate root system and set the plant back significantly. During the active growing season (spring through early fall), feed every two weeks. In winter, scale back to once a month.

Trim the Spent Flower Spike the Right Way

If the spike has turned completely brown and dry, cut it off at the base using sterile scissors or pruning shears. This redirects all the plant's energy away from maintaining a dead structure and toward building roots, leaves, and, eventually, a brand-new spike.

However, if the spike is still green with no visible buds, you have a choice. You can leave it in place, and it may produce a secondary bloom from a node along the spike. Or you can cut it at the base to encourage the plant to generate an entirely new spike, which takes longer but usually produces a fuller, more vigorous bloom. 

What Fertilizers Help Orchids Rebloom?

Not all fertilizers work the same way for orchids. The three GS Plant Foods products below are specifically formulated with orchids and blooming plants in mind. 

Each one targets a different aspect of the reblooming process, and used in rotation, they cover all the nutritional bases your orchid needs to go from resting to reblooming reliably.

1. GS Plant Foods’ Orchid Love

Orchid Love contains humic acid and other blooming agents. 

Most orchid fertilizers on the market provide only basic NPK nutrients, which can keep plants alive but often fall short of triggering the repeat bloom cycles that growers really want. GS Plant Foods’ Orchid Love takes a fundamentally different approach by combining organic kelp, liquid fish, and humic acid with dedicated blooming and rooting agents. 

It delivers nutrition, natural bio-stimulants, and growth hormones that orchids need to flower prolifically season after season. Plus, it’s easy to use. Simply mix 1–2 oz per gallon and use every watering.

The liquid kelp is rich in micronutrients that reduce plant stress and accelerate blooming, while the liquid fish provides organic nitrogen for robust foliage and root development. Its all-natural, low-salt formulation eliminates the risk of root burn, making it safe for all orchid varieties, including Phalaenopsis, Cattleya, Dendrobium, Oncidium, and Vanda. 

2. GS Plant Foods Flower Power

Flower Power contains organic kelp and trace minerals.

Flower Power takes a broader approach to bloom-boosting nutrition, built on a base of organic fish, kelp, and ocean plant extracts that deliver a wide spectrum of micronutrients, enzymes, and chelating agents for rapid plant absorption. While not orchid-specific like Orchid Love, its formulation is well-suited to orchid growers who also maintain mixed flowering collections and want a single concentrate that performs across the board. 

The organic fish and kelp base provides a steady supply of nitrogen and trace minerals that support root strength, foliage health, and flower development without the salt buildup associated with synthetic alternatives. 

It also contains beneficial microbes that enrich the growing medium with nitrogen-fixing bacteria and improve mineral uptake at the root zone, which can be particularly valuable for orchids potted in bark-based mixes where nutrient retention is naturally low. To use, simply mix 1–2 oz per gallon and apply monthly as a soil drench or foliar spray during blooming.

3. GS Plant Foods Grower's Honey

Grower’s Honey can be applied every 1–2 weeks. 

Grower's Honey approaches orchid nutrition from a different angle than traditional bloom-boosting fertilizers. Rather than relying solely on NPK ratios to drive flowering, its formulation centers on 18 L-amino acids derived entirely from plant-based proteins. 

By supplying these amino acids in a pre-formed state, Grower's Honey allows orchids to redirect the energy they would normally spend manufacturing amino acids internally toward root development, leaf health, and flower production instead. 

The supporting NPK ratio of 4-3-3 is deliberately moderate, providing a steady baseline nutrition without the risk of overfeeding that can stall orchid flowering cycles. To use, mix 3 oz per gallon and apply every 1–2 weeks during active growth.

Frequently Asked Questions (FAQs)

Why won't my orchid rebloom even with proper care?

The most likely causes are insufficient light and the absence of a nighttime temperature drop. Even orchids receiving adequate water and fertilizer will stall indefinitely if the light is too dim or the temperature stays consistently warm around the clock. 

It is also worth checking the roots. If the roots inside the pot are brown, mushy, or have largely rotted away, the plant does not have the physical infrastructure to support a new spike, regardless of what you do on the surface.

Should I cut the orchid flower spike after blooms fall off?

It depends on the condition of the spike. A brown or yellowing spike should be cut at the base since it is no longer viable and drains energy the plant could use for new growth. 

However, a green spike gives you two options: leave it and potentially get a secondary bloom from a side node within a few months, or cut it at the base to push the plant toward generating a fresh, more vigorous spike from the crown.

How many times a year can a Phalaenopsis orchid bloom?

Under ideal indoor conditions, a healthy Phalaenopsis can bloom once or twice per year, with each bloom period lasting 8 to 16 weeks. With consistent care and deliberate temperature manipulation, some growers successfully trigger two full bloom cycles per year.

Do orchids need to be repotted to rebloom?

Not always, but sometimes, repotting is exactly what the plant needs. Orchids should generally be repotted every 18 to 24 months, or when the bark medium has broken down into a dense, soggy mass that no longer drains freely.

How effective is GS Plant Foods Orchid Love for reblooming?

GS Plant Foods’ Orchid Love is formulated to trigger repeat bloom cycles using a combination of organic kelp, liquid fish, humic acid, and dedicated blooming agents that deliver the natural bio-stimulants and growth hormones orchids need to produce new flower spikes season after season. 

Its gentle, low-salt formula nourishes roots, leaves, and spikes without the risk of root burn, making it safe for all orchid varieties including Phalaenopsis, Cattleya, Dendrobium, Oncidium, and Vanda.
