A Month-by-Month Gardening Calendar for Lahore

Gardening in Lahore is a game of timing. The plant list matters far less than the fortnight you put it in the ground, because the climate gives you narrow windows and then punishes you for missing them with either 45°C heat or a monsoon that washes seedlings out.

This is the rhythm we work to. Adjust it by a week or two in either direction depending on the year.

January and February — the dormant window

The best time of year for structural work. Deciduous trees are bare, so their shape is visible and pruning cuts heal into the spring flush. Prune fruit trees and roses, plant bare-root and semi-mature trees, and get any hardscape done while the ground is workable and nothing is actively growing. Winter annuals — pansies, petunias, calendula, dianthus — are at their peak, so keep deadheading them.

March — the spring flush

Everything wakes up at once. Feed the lawn for the first time, scarify out the winter thatch and aerate if the soil is compacted. This is the best month of the year to lay turf: warmth for rooting without summer water demand. Start warm-season vegetables and plant summer flowering shrubs.

April — the last comfortable month

Get everything done now that you do not want to be doing in June. Finish planting, mulch every bed to 5–7cm to hold moisture through what is coming, and service the irrigation properly: check every emitter, flush the lines, reset the controller. April is when we find the faults that would otherwise kill a garden in May.

May and June — survival mode

Do not plant. Do not prune hard. The job in these months is keeping alive what you already have. Water early in the morning rather than the evening, and water deeply and less often so roots go down rather than sideways. Raise the mower height — longer grass shades its own roots and holds moisture far better than a close cut.

• Mow higher, not shorter, through peak heat.
• Water between 4am and 7am; evening watering leaves foliage wet overnight and invites fungus.
• Check container plants daily — pots on a roof or terrace can dry out inside a single afternoon.
• Watch for red spider mite on stressed plants; it thrives in exactly these conditions.

July and August — monsoon

The rain solves the water problem and creates a drainage one. Check that beds are not sitting waterlogged, clear roof and terrace outlets before the first heavy fall, and turn the irrigation controller down or off rather than letting it run through downpours. Fungal disease spikes now, so improve air movement by thinning dense shrubs. It is also the best window of the year for planting trees, which establish beautifully in warm, wet soil.

September — the two weeks that matter most

If there is one entry on this calendar to act on, it is this one. Winter annuals need to be sown or planted in September to flower properly from November onward. Sow late and you get leggy plants and a short, disappointing display. This is when good winter gardens are decided, months before anyone sees them.

Also feed the lawn again as the heat breaks, and start cool-season vegetables: spinach, coriander, radish, peas, carrots.

October and November — the second planting season

The most pleasant months to garden and the second-best window for turfing. Plant out the winter annuals raised in September, put in shrubs and perennials while the soil is still warm enough to root before winter, and divide anything overgrown. Reduce irrigation frequency as evaporation drops — most Lahore gardens are heavily over-watered in autumn out of habit.

December — tidy and plan

Growth slows. Clear fallen leaves off the lawn so it does not yellow underneath, mulch tender plants, and take the opportunity to plan next year's changes while you can see the garden's bare structure. Any redesign is far cheaper to decide now than in April.

The two dates that change a Lahore garden most are the September sowing and the April irrigation service. Miss either and the year gets harder.
