If your orchid has fewer flowers than you’d like, small changes to feeding and care can make a big difference. A few targeted tweaks to fertilizer, watering, and light will help most potted orchids produce more blooms and healthier foliage. Florist Spencer Falls shared practical, budget-friendly tips that are easy to follow at home.
Why orchids need special fertilizer and what to look for
Most store-bought orchid mixes are bark or inorganic and do not supply all the nutrients a plant needs long term. That makes fertilizing a must for sustained flowering. Choose a product formulated for orchids so it provides both macronutrients and trace elements.

Look for an orchid-specific formula that lists micronutrients and a balanced NPK. One commonly recommended option is Better-Gro Orchid Plus, which offers nutrients tailored to epiphytic orchids and is widely available at an affordable price.
How to feed orchids: practical steps for better blooms
When and how often to fertilize
Feed more frequently while the plant is actively growing and reduce during slower periods. A simple approach is to fertilize one to two times a month during the growing season.
Mixing and applying fertilizer
- Use a water-soluble orchid fertilizer for quick uptake.
- Follow the label for dilution; a weak solution is safer than a strong one.
- Apply the fertilizer when the potting medium is moist to avoid root burn.
- Allow excess water to drain; never let the plant sit in standing liquid.
Fast-acting nitrate nitrogen in a formula helps leaves and roots recover quickly and supports the energy orchids need to set blooms.
Epsom salt: the occasional magnesium boost
Adding a small amount of Epsom salt occasionally can help orchids maintain bright, healthy leaves. Magnesium supports chlorophyll production, which can improve leaf color and overall vigor.
- Use Epsom salt sparingly — roughly once a month is sufficient for most plants.
- Dissolve a light amount in water and apply as a supplemental feed or foliar rinse.
- Do not replace a balanced fertilizer with Epsom salt; it should be an occasional boost.
Magnesium supplements are especially useful when leaves look pale or lack luster despite regular feeding.
Water and light: the non-negotiable partners to fertilizing
Feeding alone won’t produce flowers if water and light are wrong. Orchids prefer bright, indirect light and a potting mix that drains well. Too much water is the most common mistake.
- Water only when the medium is dry to the touch or the bark has lightened.
- Water thoroughly, then let the mix dry before the next soak.
- Keep plants out of pooled water; good drainage prevents root rot.
- Leaf color is a reliable light gauge: very dark green leaves often mean the plant needs more light.
Many orchids die from overwatering, not neglect. Adjust frequency by season and environment.
Quick checklist for feeding orchids that bloom more
- Choose an orchid-specific fertilizer with micronutrients.
- Feed one to two times monthly during active growth.
- Use a weak, water-soluble mix and water the plant before fertilizing.
- Try a light Epsom salt treatment about once a month for magnesium.
- Provide bright, indirect light and avoid overwatering.
