The Essential Buying Guide for Citrus Tree Fertiliser
Citrus trees—think oranges, lemons, limes, and grapefruit—need special food to grow big and produce yummy fruit. Choosing the right fertiliser makes a huge difference. This guide helps you pick the best food for your sunny-day trees.
Key Features to Look For
When you shop for citrus fertiliser, certain numbers and words matter most. These tell you what the food contains.
1. The NPK Ratio
You will always see three numbers on a fertiliser bag, like 10-10-10 or 5-1-3. These stand for Nitrogen (N), Phosphorus (P), and Potassium (K).
- Nitrogen (N): This helps your tree grow lots of green leaves. Citrus trees love nitrogen!
- Phosphorus (P): This builds strong roots, especially important for young trees.
- Potassium (K): This helps the tree fight off sickness and makes the fruit taste better.
For mature citrus, look for formulas where the first number (N) is higher, like a 15-5-10 ratio. This boosts leaf growth.
2. Micronutrients (Trace Elements)
Citrus trees are greedy eaters. They need more than just NPK. Good citrus fertilisers include these tiny but mighty elements:
- Magnesium: Stops leaves from turning yellow between the veins.
- Iron: Keeps the leaves deep green.
- Zinc: Helps new shoots grow properly.
Important Materials and Types
Fertilisers come in different forms. Your choice depends on how fast you want the food to work and how much effort you want to put in.
1. Organic vs. Synthetic
- Organic Fertilisers: These come from natural sources like compost, manure, or bone meal. They feed the soil slowly, improving its health over time. They are safer for pets and the environment.
- Synthetic Fertilisers: These are made in a factory. They release nutrients quickly, giving your tree an immediate boost.
2. Granular vs. Liquid
- Granular (Slow-Release): You spread these pellets around the base of the tree. They release food slowly, often lasting 1 to 3 months. This is easy for most gardeners.
- Liquid: You mix these with water and pour or spray them on. They work fast but you must apply them more often.
Factors That Improve or Reduce Quality
The quality of your fertiliser affects how well your tree responds.
Quality Boosters:
- Chelated Micronutrients: When minerals like iron or zinc are “chelated,” the tree can absorb them much easier, even if the soil is alkaline (chalky). This prevents deficiencies quickly.
- Sulphur Content: Some citrus foods contain sulphur. This helps lower the soil pH slightly, which citrus trees prefer.
Quality Reducers:
- Too Much Salt: Synthetic fertilisers with very high salt content can sometimes burn the roots if you use too much or if it does not rain after application. Always follow the label directions!
- Old or Poorly Stored Product: If the fertiliser has gotten wet or sits outside for years, its effectiveness decreases. Buy fresh bags.
User Experience and Use Cases
How you use the fertiliser matters just as much as what you buy.
When to Feed Your Tree
Citrus trees grow most actively in warm weather. Feed them heavily from early spring through late summer. Stop feeding completely in the fall and winter when the tree rests. Over-fertilising during winter can cause problems.
Application Tips
Always spread the fertiliser evenly across the “drip line” (the area under the outer edge of the branches). Do not pile it right up against the trunk—this can burn the bark. Water thoroughly after applying granular food to help the nutrients move toward the roots.
10 Frequently Asked Questions (FAQ) About Citrus Fertiliser
Q: How often should I feed my citrus tree?
A: Generally, feed your tree once a month during the main growing season (spring through summer). Always read the specific instructions on your chosen product.
Q: Can I use general garden fertiliser on my lemon tree?
A: You can, but it is not ideal. General fertilisers often lack the high levels of magnesium and zinc that citrus trees specifically need to prevent yellowing leaves.
Q: What does it mean if my lemon leaves are yellowing?
A: Yellow leaves usually mean the tree lacks a key nutrient, often magnesium or iron. A fertiliser high in these micronutrients will help correct this.
Q: Should I fertilise a brand new citrus tree?
A: Wait about four to six weeks after planting before you start feeding. Young trees need time to settle their roots first. Start with a half-strength dose.
Q: Is organic or synthetic fertiliser better for my orange tree?
A: Organic is great for long-term soil health. Synthetic provides faster results when you need a quick nutrient boost. Many experienced growers use a combination of both.
Q: Should I fertilise my citrus tree in the winter?
A: No. Most citrus trees slow down or stop growing when it is cold. Fertilising during this rest period can lead to nutrient burn or wasted food.
Q: What is the best NPK ratio for mature fruit-bearing trees?
A: Look for higher nitrogen. Ratios like 15-5-10 or anything similar where the first number is the largest works well for encouraging leaf and fruit production.
Q: Can I over-fertilise my tree?
A: Yes. Too much fertiliser, especially synthetic types, can cause “fertiliser burn,” damaging the roots and leaves. Always measure carefully.
Q: How do I apply slow-release pellets?
A: Spread the recommended amount evenly under the canopy of the tree, avoiding the trunk. Water deeply afterward so the nutrients begin to dissolve and move down.
Q: Do potted citrus trees need different food?
A: Yes, potted trees need feeding more often because watering washes nutrients out of the container faster. Use a slightly diluted liquid feed more frequently, or use a slow-release product designed for containers.
