Mulching Made Simple

I'll show you how to keep your garden cool and save water, and reveal the one trick you must do on day one.

What is mulching

When soil sits bare, the sun bakes it and water disappears fast. A thin blanket of shredded leaves, straw, or gravel shades the surface, slows evaporation, and keeps a crust from forming. It also smothers many weed seeds and slowly feeds soil life, stretching the time between waterings, especially in hot, windy climates.

Extreme summer heat

In places like Multan, June temperatures can hit 45 °C, turning a pot’s top few centimetres into a furnace for fine roots. Mulch acts like a sun-shield, cutting down the heat that reaches the soil and giving your plants a cooler, more stable environment, which can mean the difference between wilting and thriving.

Choosing mulch

Pick whatever’s cheap and close at hand. Light-coloured straw or pale gravel reflects sunlight, keeping soil cooler in the scorching summer, while darker compost or shredded leaves hold a bit more heat, which can be handy in chilly winter months. The key is to use what you can find without spending a fortune, and to avoid anything treated with chemicals.

How to apply

First, pull any weeds and break up that hard crust on the surface. Give the soil a good soak so it’s moist all the way through, not just wet on top. Then shred your leaves or chop straw into short pieces, and spread a layer, five to seven centimetres for beds, two to three for pots, leaving a couple of centimetres of bare soil around each stem, which helps roots breathe and prevents rot.

Rooftop rule

On a windy roof, dry leaf flakes or rice husk can disappear overnight, so give them a quick spray until they darken, then press the damp clumps with your palm. If the breeze is relentless, toss a handful of pebbles or a loose ring of coir rope on top for the first week to keep everything in place, and the mulch will stay moist longer.

Common mistakes

Avoid a 'volcano' pile of mulch up a trunk, keep the collar bare so air can circulate. Don’t mulch over dry soil, otherwise the layer stays dry and defeats the purpose. Fresh sawdust or wood chips can steal nitrogen, yellowing leaves, and plastic sheets trap heat while blocking water from reaching roots, which can invite fungal problems.

The one trick

Here’s the one habit that makes all the difference: wet your mulch on the first day. Give it a good spray until it’s damp, press it down, and it will stick where you need it, even on breezy rooftops. This simple step locks in moisture and prevents the layer from blowing away, giving your plants a head start each morning.
