When to Prune Fruit Trees: Grapes, Guava, Lemon, Mulberry
When to prune fruit trees depends on one question: does the tree drop its leaves in winter? Leaf dropping trees (grapes, mulberry, fig, peach, pomegranate) are pruned while bare, from December to January on the plains. Evergreens (lemon and other citrus, guava) are pruned lightly after the frost risk passes, usually February to March, and never hard in midwinter. Get that split right and most pruning mistakes disappear.
Pruning calendar at a glance
- Grapes: December to early January, fully dormant
- Mulberry (shahtoot), fig (anjeer), peach (aaru), pomegranate (anar): late December to January
- Lemon, kinnow, other citrus: light trim in late February to March, after frost
- Guava (amrood): after the winter crop is picked, February to March
- Karachi: no frost, so citrus and guava can be trimmed from January
- Hills: push everything 3 to 4 weeks later

Why winter pruning works for some trees and harms others
A bare deciduous tree is asleep. Its sugars are stored in the roots and trunk, there are no leaves to lose, and you can see every branch clearly. Cuts made now push strong new shoots in spring, which is exactly where next year’s fruit forms on grapes, figs and mulberries.
An evergreen like lemon is not asleep. It keeps its leaves and slowly feeds through winter. Cut it hard in January and two things go wrong: it loses leaves it needs, and any regrowth it pushes is soft and gets burnt by the next frost. University extension advice for citrus is consistent: light cuts, after frost danger has passed.
Which tree, when, and how much?
| Tree | When (plains) | How much | Fruits on |
|---|---|---|---|
| Grapes | Dec to early Jan | Heavy: most of last year’s growth | New shoots from last year’s canes |
| Mulberry | Late Dec to Jan | Moderate to heavy; can be kept small | New spring shoots |
| Fig | Jan | Light to moderate | New and last year’s wood |
| Peach | Jan | Moderate; keep an open centre | Last year’s red shoots |
| Pomegranate | Jan to Feb | Light; remove suckers | Short spurs on older wood |
| Citrus | Late Feb to Mar | Light only | Tips of new side shoots |
| Guava | After harvest, Feb to Mar | Light to moderate | New shoots |
How to prune grapes in winter
Grapes fruit on new green shoots that grow from canes made last summer. So winter pruning is about keeping a few good buds on young wood and removing the rest.
- Find the main arms (the permanent branches along your wire or pergola).
- Each arm has brown canes from last summer. Cut each one back to a short spur of a couple of buds.
- Remove weak, thin and dead canes entirely.
- Do it while fully dormant. The RHS notes late winter cuts can “bleed” sap, which looks alarming but usually stops once leaves open.
- Keep the best cut canes: they root easily (see our grape growing guide).
How to prune a lemon tree (and why not in January)
Lemons need very little. Their flowers form at the tips of new side shoots, so heavy pruning removes next year’s fruit. The RHS suggests removing crossing and wayward shoots in late winter and cutting back only vigorous growth.
- Cut out dead and frost killed twigs, but only once new growth shows, so you can tell what is truly dead.
- Remove shoots growing from below the graft joint (they come from the rootstock and are thorny and vigorous).
- Thin crowded inner branches so light reaches the middle.
- Shorten one or two overly long shoots to keep the shape. Stop there.
Potted lemons are covered in our lemon plant in a pot guide.
How to prune guava
Guava fruits on new shoots, so a light trim after harvest gives more fruiting wood. Remove water shoots (straight, fast upward stems), suckers from the base, and branches that cross. Shorten long outer branches by a little to keep the tree within reach. A guava allowed to grow tall gives fruit only the parrots can reach.
Pruning mulberry
Mulberry is forgiving and vigorous. In a small garden or a pot, cut last year’s shoots back hard each winter to keep a compact head. In the ground, prune more lightly and remove only dead, crossing and low branches. Fruit appears on the new shoots in spring.
How much to prune a fruit tree, and the cuts that matter
The one third rule and the outward bud
On any tree, never take more than about a third of the living branches in one year. And always cut just above a bud that points outward, sloping away from it. The new shoot grows the way that bud faces, so outward buds open the tree up and stop branches crossing into the middle.
- Tools: sharp bypass secateurs for twigs, loppers for thicker stems, a small pruning saw for branches. Our gardening tools guide lists what is worth buying.
- Clean blades: wipe with alcohol between trees to avoid spreading disease.
- No stubs: cut back to a bud, a side branch or the collar at the trunk.
What not to prune in winter
- Citrus, guava, mango and other evergreens in frost weeks.
- Frost burnt growth on anything, until new growth appears.
- Newly planted trees beyond a light shaping cut.
Most pruning injuries come from ladders and saws, not the tree. Use a steady ladder with someone holding it, never lean out past the rails, and leave large branches over roofs, wires or roads to a professional. Wear gloves for citrus thorns and fig sap, which can irritate skin, worse in sunlight. Keep children clear of falling branches.

Fruit tree pruning questions
When should you prune fruit trees in Pakistan?
Leaf dropping trees in December to January while bare; citrus and guava lightly in late February to March after frost. In Karachi, without frost, evergreens can be trimmed from January.
Can I prune my lemon tree in winter?
Only lightly, and better after the last frost. Hard winter cuts expose the tree and invite frost damage on new growth.
How many buds should I leave on a grape vine?
On a spur pruned vine, leave a short spur of a couple of buds on each of last year’s canes. Those buds give this year’s fruiting shoots.
How much can you cut off a fruit tree at once?
No more than about a third of the living branches in a year. Heavier cuts trigger a flush of leafy water shoots rather than fruit.
Do I need to seal pruning cuts?
Usually not. Clean cuts just above a bud or at the branch collar seal themselves; paints can trap moisture.
How do I prune a guava tree to get more fruit?
After harvest, remove water shoots, suckers and crossing branches and shorten long outer stems a little. Guava fruits on new growth, so a light trim encourages more of it.
Can mulberry be pruned hard?
Yes. Mulberry handles hard winter pruning well and is often cut back to a compact head every year in small gardens.
Why did my tree make leaves but no fruit after pruning?
It was probably cut too hard, or at the wrong time for that tree. Heavy pruning pushes leafy growth; next year take less.
