How to grow orchids! Water and fertilize to keep them blooming all year round

The photo clearly shows a small jar of **lemon slices** fermenting in liquid — bright yellow citrus peels suspended in a cloudy brew. This article explains how to use that exact ingredient, a **fermented lemon peel tea**, safely and effectively as a supplemental fertilizer for orchids. The technique taps the nutrients and microbial activity in citrus peels while respecting orchids’ sensitive roots.

Why lemon peels? Botanical facts you can trust

**Citrus peels** contain soluble **potassium (K)** and small amounts of phosphorus and micronutrients, plus sugars that feed beneficial microbes during fermentation. When properly prepared and diluted, a fermented citrus peel extract (a type of fermented plant juice) can release these soluble nutrients and microbes into the water you give your orchid. Remember: this is a supplement — it does not replace basic care like correct **light**, **watering**, **drainage**, and balanced commercial orchid fertilizer.

Step-by-step: make a safe fermented lemon peel tea (visual match to the jar)

• Ingredients and gear: 200 g chopped lemon peels (no seeds), 1 L non-chlorinated water, 1 tablespoon molasses or cane sugar, a clean glass jar with lid, mesh or cloth for straining.
• Step 1 — Chop and fill: Place the chopped peels in the jar and cover with the water. Add the molasses and stir to dissolve; this feeds fermentation.
• Step 2 — Ferment: Close the jar loosely (allow gas to escape) and keep at room temperature (18–24 °C / 65–75 °F) out of direct sun for 7–10 days. Open once a day to release gases and stir — aim for a mild ferment, not a foul-smelling rot. The jar in your picture shows mild cloudiness and foam typical of an active ferment.
• Step 3 — Strain and store: After 7–10 days, strain the liquid into a clean container. Discard solids into compost. The liquid is your concentrated lemon peel tea (do not use undiluted).

How to apply to orchids — exact doses and frequency

Orchids are sensitive. Use the fermented lemon tea conservatively and always dilute.

• Concentrate dilution for root drench: Mix 1 part lemon tea with 100 parts water (1:100). Example: 10 mL concentrate + 1 L water.
• Concentrate dilution for foliar spray: Mix 1:200 (5 mL concentrate + 1 L water). Spray in the morning only, avoiding open flowers.
• Frequency — growing season (spring–summer): Root drench every 3 weeks. Foliar spray every 2 weeks if humidity is low.
• Frequency — rest season (autumn–winter): Reduce to one root drench every 6–8 weeks or stop entirely for plants in strict rest.
• Expectations: Any improved vigor or better bud set will appear over several weeks to a couple of months; this is a slow supplement, not an instant bloom trigger.

Practical tips from experience

• Measure pH: Citrus brew can be acidic. After dilution the pH usually lands in a safe range, but check — orchids prefer about pH 5.5–6.5 in the potting medium. Adjust water if needed.
• Aerate, don’t anaerobe: The jar in the photo is fine if you vent daily. Avoid long, sealed anaerobic brews that go rotten — they can produce phytotoxic compounds.
• Combine with balanced fertilizer: Use a commercial orchid fertilizer on a regular schedule (e.g., half-strength every 1–2 weeks during growth). The lemon tea is a supplementary potassium/microbial boost, not a full N-P-K replacement.
• Use clean tools: Always strain and store the diluted mix in a clean sprayer or watering can to prevent pathogens.
• Adapt to potting mix: Bark mixes dry faster and benefit from small, frequent, diluted applications. Sphagnum moss holds moisture — reduce frequency to avoid root rot.

Common mistakes to avoid (real botanical consequences)

• Pouring undiluted fermented lemon tea onto orchid roots — can cause root burn and acid stress.
• Using a foul-smelling, moldy brew — this indicates anaerobic decay and possible toxins; discard and restart with better venting.
• Relying solely on citrus tea and skipping balanced fertilization — lemons do not provide adequate nitrogen for leaf growth.
• Applying during winter rest — excess nutrients and moisture at low temperatures invite rot rather than blooms.
• Getting spray on flowers — citrus residue can spot petals; only mist foliage in the morning and avoid blooms.

Conclusion — start small, watch your orchids respond

That jar of fermented lemon slices can become a useful **supplement** for orchids when prepared carefully and used at the right dilution (1:100 root drench, 1:200 foliar). Expect measurable benefits over several weeks to months: steadier bud development and a gentle boost of potassium and microbes. Always pair this tip with correct **light**, measured **watering**, good **drainage**, and a balanced orchid fertilizer. Try one diluted application this growing season, keep notes on how your plant responds, and adjust frequency accordingly — your orchids will thank you with healthier leaves and more reliable blooms.

Action now: If your jar looks like the photo, vent it daily, strain after 7–10 days, dilute 1:100 for a test root drench, and schedule repeats every three weeks during spring and summer.
