The Plumeria Fertilizer and Nutrition Guide offers comprehensive advice on how to properly feed plumeria to achieve optimal growth and vibrant blooms. This guide covers the critical aspects of plumeria nutrition, including how to select the right fertilizers based on your plant’s specific needs, balance essential nutrients like nitrogen, phosphorus, and potassium, and manage soil pH to enhance nutrient uptake. It also explores the use of supplements and soil additives to support sustained health and vitality, ensuring your plumeria remains strong and healthy throughout the year. Whether you’re aiming to boost growth during the active season or enhance blooming, this guide provides the essential information to tailor your fertilization practices for the best results.
Seasonal Fertilizer Calendar for Plumeria by Tree Age
Seasonal Fertilizer Calendar for Plumeria by Tree Age
Use this seasonal calendar to guide fertilizer application based on the age of your plumeria trees. Young trees (1–3 years) and mature trees (4+ years) have different nutrient demands, and adjusting your schedule accordingly will maximize health, growth, and blooming performance.
Fertilizer Calendar by Tree Age and Season (Zone 10 Example)
| Season | Young Trees (1–3 Years) | Mature Trees (4+ Years) | Feeding Focus | Notes |
| Early Spring (Mar–Apr) | Apply balanced slow-release (e.g., 4-6-4) + fish emulsion every 2–3 weeks | Apply Excalibur IX or similar slow-release bloom-supporting formula | Activate growth, root development | Water first; avoid bloom formulas in young trees |
| Late Spring (May) | Continue light liquids; top-dress with compost or worm castings | Begin liquid bloom boosters (e.g., 2-3-2) every 10–14 days | Leaf expansion, early bud support | Monitor for yellowing or slow branch growth |
| Early Summer (Jun) | Optional mild kelp foliar spray if showing early bud signs | Maintain bloom formulas; foliar Epsom + kelp every 2–3 weeks | Encourage blooms and strengthen tissues | Flush containers monthly to avoid salt buildup |
| Mid to Late Summer (Jul–Aug) | Stop fish emulsion; switch to light compost tea if needed | Continue bloom formulas; reduce nitrogen | Flowering + post-bloom recovery | Evaluate if tree shows signs of stress or overfeeding |
| Fall (Sep–Oct) | Stop fertilizing to allow for dormancy prep | Final liquid feed or kelp foliar in early Sept only | Prepare for dormancy | No nitrogen; let the tree harden off |
| Winter (Dormant) | None unless under grow lights | None unless overwintering indoors actively growing | Rest period | Resume feeding in spring when new leaves appear |
