How to Feed Citrus & Fruit Trees: Complete Guide to Citrus 'n Fruit Trees Plant Food in Pakistan
A lemon tree on the balcony, a kinnow in the courtyard, or a guava in the garden: fruit trees are among the most rewarding plants to grow at home in Pakistan. But many gardeners struggle with yellow leaves, flowers that drop without setting fruit, or small, sour harvests. Fruit trees need steady, balanced nutrition through the whole year, from new leaves to flowers to ripening fruit. Citrus 'n Fruit Trees Plant Food is a water-soluble fertiliser made for exactly this. This guide explains how to use it and how to plan a full-year feeding schedule for your fruit trees.

What Is Citrus 'n Fruit Trees Plant Food?
Citrus 'n Fruit Trees Plant Food – All Purpose is a premium water-soluble fertiliser made for citrus and other fruit-bearing plants. It provides balanced main nutrients plus micronutrients to support every stage of a fruit tree's year: new leaves, strong roots, flowering, fruit set, and fruit development.
It dissolves completely in water and can be used as a soil application at the roots or as a foliar spray on the leaves.
What Fruit Trees Need
- Nitrogen for new leaves and shoots, which carry next season's flowers.
- Phosphorus for strong roots and good flowering.
- Potassium for fruit size, sweetness, colour, and resistance to heat and disease.
- Micronutrients, especially iron, zinc, and manganese. Citrus is particularly sensitive to shortages, which are very common in Pakistan's alkaline soils and hard water.
An all-purpose fruit tree formula supplies all of these together, so trees stay green and productive.
Benefits
- Healthy growth and greener, fuller leaves.
- Better flowering and fruit setting.
- Bigger, tastier, better-coloured fruit.
- Stronger roots and overall plant health.
- Better resistance to heat, stress, and disease.
- Fast absorption through roots and leaves.
How Much to Use
| Method | Dose | How Often |
|---|---|---|
| Soil application | 5 g (1 level teaspoon) per litre of water | Every 10–15 days in the growing season |
| Foliar spray | 2–3 g per litre of water | Every 10–15 days in the growing season |
How Much Solution per Tree
| Tree Size | Solution per Feed (Soil Application) |
|---|---|
| Small pot (12–14 inch) | About 0.5–1 litre |
| Large pot or drum (18–24 inch) | About 1–2 litres |
| Young tree in the ground (1–3 years) | About 2–4 litres |
| Mature tree in the ground | About 5–10 litres, spread around the drip line |
Use either soil application or foliar spray at each feed, not both on the same day.
How to Apply
Soil Application
- If the soil is dry, water the tree first.
- Dissolve 5 g per litre of water.
- Pour the solution in a ring under the outer edge of the canopy (the drip line), where most feeding roots are, not against the trunk.
- Apply in the early morning or evening.
Foliar Spray
- Dissolve 2–3 g per litre of water.
- Spray evenly on both sides of the leaves in the early morning or evening.
- Foliar feeding is especially useful for quickly greening pale leaves and for supporting trees during flowering.
Citrus Feeding Calendar for Pakistan
This calendar suits lemon, kinnow, malta, and orange in the plains of Punjab and Sindh. Citrus produces new growth in flushes, and feeding should follow these flushes.
| Month | Tree Stage | What to Do |
|---|---|---|
| Late January–February | Spring flush begins | Add compost around the tree. Start feeding every 10–15 days. |
| March–April | Flowering and fruit set | Continue feeding. Foliar sprays help reduce flower drop. Keep watering steady. |
| May–June | Young fruit growing; extreme heat | Feed every 15 days. Water deeply and regularly; mulch the soil. |
| July–August | Monsoon flush | Feed every 15 days. Ensure good drainage. |
| September–October | Autumn flush and fruit enlarging | Continue feeding. A high-potassium feed helps fruit size and sweetness. |
| November–January | Ripening, harvest, and winter rest | Reduce or stop feeding in the coldest weeks. Resume after harvest as the spring flush begins. |
Guide by Fruit Tree
Lemon (Nimbu) and Lime
Lemons flower several times a year, especially in pots. Feed every 10–15 days from February to October. Lemons are the citrus most prone to yellow leaves, so add a micronutrient spray if new leaves are pale.
Kinnow, Malta, and Orange
Follow the citrus calendar above. Steady feeding during fruit development, together with even watering, gives larger, juicier fruit and reduces splitting.
Guava (Amrood)
Guava fruits in two main seasons, monsoon and winter. Feed every 15 days during active growth and before each flowering. Winter guavas are usually sweeter and better quality.
Mango (Aam)
Mature mango trees flower in late winter and spring. Avoid heavy feeding in autumn, which can push leafy growth instead of flowers. Feed after harvest to rebuild the tree, and again from fruit set onwards. Young mango trees benefit from regular feeding during the growing season.
Pomegranate (Anaar)
Feed every 15 days from spring through fruit development. Even watering helps prevent fruit cracking, which is common in hot, dry weather.
Figs, Grapes, Mulberries, and Berries
Feed during active growth from spring to late summer, and stop as plants go dormant in winter.
Growing Fruit Trees in Pots
Lemons, kinnow, figs, pomegranates, and dwarf guavas grow well in large pots on rooftops and balconies. Container trees need more regular feeding, because nutrients wash out each time you water.
- Use a pot of at least 16–18 inches for a young tree, moving up to 20–24 inches or a half drum as it grows.
- Use a well-drained mix such as garden soil, compost, coco peat, and perlite. See our potting mix and soil media guide.
- Feed every 10–15 days in the growing season with 5 g per litre.
- Top-dress with vermicompost every 2–3 months.
- Give at least 6 hours of direct sun.
Common Problems and Fixes
| Problem | Likely Cause | What to Do |
|---|---|---|
| New leaves yellow with green veins | Iron or zinc deficiency (very common in alkaline soil) | Spray Grow Magic micronutrients |
| Older leaves yellow between the veins | Magnesium deficiency | Use Epsom Salt |
| Whole tree pale, slow growth | General lack of nutrition | Feed regularly with Citrus 'n Fruit Trees Plant Food |
| Flowers or small fruit dropping | Irregular watering, heat stress, or poor nutrition | Water evenly, mulch, and keep up regular feeding |
| Fruit splitting | Dry spell followed by heavy watering or rain | Keep soil evenly moist and mulch |
| Small or sour fruit | Low potassium or water stress during fruit growth | Feed during fruit development and add High K 5:15:45 |
Combining with Other Fertilisers
- Healthy soil: Spread organic compost around the drip line in late winter, and top-dress with vermicompost through the year.
- Micronutrients: Citrus in Pakistan very often needs extra iron and zinc. Spray Grow Magic at the start of each new flush.
- Fruit quality: During fruit development, you can alternate with High K 5:15:45 for bigger, sweeter fruit.
- Long-term feeding: If you use Osmocote Plus for steady background feeding, use this plant food at half strength or less often.
Apply one water-soluble feed at a time and leave about 10 days between different products. For more on choosing formulas by stage, see our NPK fertilizers guide.

Best Practices and Common Mistakes
Best Practices
- Feed regularly through the growing season, following the tree's growth flushes.
- Apply around the drip line, not at the trunk.
- Water the soil first if it is dry, then feed.
- Spray in the cool of the morning or evening.
- Keep watering steady, especially during flowering and fruit development.
- Mulch around the tree to keep roots cool in summer.
Common Mistakes
- Feeding heavily in the coldest winter weeks, when trees are resting.
- Pouring fertiliser against the trunk.
- Using a stronger dose than recommended.
- Letting the soil dry out completely during fruit growth, then watering heavily, which leads to fruit drop and splitting.
- Ignoring yellow young leaves. In citrus this is usually a micronutrient problem that NPK alone will not fix.
Frequently Asked Questions
How often should I feed my lemon tree?
Every 10–15 days from February to October, with 5 g per litre as a soil application. Reduce or stop feeding in the coldest winter weeks.
Why are my lemon leaves turning yellow?
If new leaves are yellow with green veins, it is usually iron or zinc deficiency caused by alkaline soil or water. Spray Grow Magic micronutrients. If older leaves are yellowing, check for magnesium deficiency, overwatering, or a general lack of feeding.
Can I use this on other fruit plants?
Yes. It is suitable for guava, mango, pomegranate, figs, grapes, berries, and most fruit-bearing plants.
Can I use it on fruiting vegetables?
It can be used, but for tomatoes, chillies, and other fruiting vegetables a stage-based NPK programme usually gives better results. See our NPK guide.
My tree flowers but drops its fruit. Why?
Some natural fruit drop is normal. Heavy drop is usually caused by irregular watering, extreme heat, or poor nutrition. Keep the soil evenly moist, mulch, and feed regularly from flowering onwards.
Conclusion
Healthy, productive fruit trees need steady nutrition all season. Citrus 'n Fruit Trees Plant Food makes it simple: 5 g per litre at the roots or 2–3 g per litre as a spray, every 10–15 days during the growing season. Follow the tree's natural flushes, add micronutrients for citrus, keep watering even, and build healthy soil with compost. Your lemons, kinnows, guavas, and pomegranates will reward you with greener leaves and better harvests.
