Foliar Feeding Basics (And When to Use It for Plumeria)

🌿 What Is Foliar Feeding?
Foliar feeding is the process of spraying a diluted liquid fertilizer directly onto a plant’s leaves, allowing it to absorb nutrients through the foliage rather than the roots.
While not a substitute for soil fertilization, foliar feeding can provide a fast-acting nutrient boost, especially during periods of stress, slow root uptake, or early in the growing season.
🧪 How It Works
Plumeria leaves absorb nutrients through tiny pores called stomata. These pores open under the right conditions—typically in the early morning or late evening—allowing nutrients like nitrogen, magnesium, and iron to be absorbed more quickly than through roots alone.
⚠️ Foliar feeding does not replace root fertilization—it supplements it.
✅ When to Use Foliar Feeding on Plumeria
| Situation | Benefit |
|---|---|
| Early season growth | Jumpstarts energy before root systems activate |
| After transplanting or repotting | Reduces stress and improves recovery |
| Yellowing leaves (chlorosis) | Quick boost of iron or magnesium |
| During bloom push | Micronutrient spray can support flower formation |
| Heat or drought stress | Bypasses dry root zones |
| Mid-season feeding for potted plants | Refresh nutrients without repotting |
🌞 Best used as a supportive measure, especially in spring and summer.
🧴 What to Use for Foliar Feeding
Choose products that are:
- Water-soluble
- Low-salt
- Contain micronutrients like magnesium, iron, calcium, and sulfur
- Optionally contain nitrogen for green-up
Popular Foliar Spray Ingredients:
- Seaweed/Kelp extract
- Fish emulsion
- Chelated iron or micronutrient blends
- Diluted balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20)
🧪 Use at ¼ to ½ strength compared to soil application. Always follow product instructions.
🕰️ When to Apply Foliar Spray
| Time of Day | Why It Matters |
|---|---|
| Early Morning | Stomata are open, temps are cooler |
| Late Afternoon | Safe if temps are below 85°F |
| ❌ Midday (Hot Sun) | Can cause leaf burn or evaporation |
🌤️ Do not spray during intense heat, wind, or direct sun.
🪴 How to Apply Foliar Spray Correctly
- Mix properly: Dilute the product to the recommended foliar rate
- Use a fine mist sprayer: Apply evenly to the top and undersides of leaves
- Avoid runoff: A light mist is better than drenching
- Shake the bottle often: To keep nutrients suspended
- Do not fertilize open blooms: This can cause spotting
✅ Test spray a few leaves first if using a new product.
🔄 How Often Should You Foliar Feed?
| Frequency | Recommendation |
|---|---|
| General use | Every 2–4 weeks in active season |
| During stress or bloom | Every 1–2 weeks as needed |
| Dormancy | Do not foliar feed during dormancy |
❌ Common Mistakes to Avoid
- Overapplying or using full-strength fertilizer (can burn leaves)
- Spraying in full sun or heat
- Spraying during dormancy (ineffective and risky)
- Replacing soil fertilizer with foliar only (leads to deficiencies)
🧾 Beginner Recommendations
| Product Type | Good Options |
|---|---|
| Kelp/Seaweed Spray | For stress recovery and growth kickstart |
| Chelated Iron/Magnesium | For chlorosis (yellow leaves with green veins) |
| Balanced Liquid Fertilizer | For all-purpose feeding (diluted) |

🌺 Conclusion
Foliar feeding is a powerful tool when used correctly: it delivers quick nutrition, supports blooming, and helps stressed plumeria bounce back faster. While it doesn’t replace soil feeding, it’s a smart way to fine-tune plant health during the growing season, especially in containers or tight root zones.
