Top tips to prepare your garden for incoming rain

Why you should give your garden a cup of chamomile tea before it rains

Why you should give your garden a cup of chamomile tea before it rains

Mark Dwelly, Head Gardener at Audley Stanbridge Earls, comments:

“After back-to-back heatwaves, scorched lawns, and weeks under hosepipe bans, seeing rain on the UK forecast feels like a massive relief. But relying on a sudden downpour to fix a heat-shocked garden is a trap."

“When soil bakes through repeated hot spells, it forms a hard, crusty layer that becomes hydrophobic. It repels water like concrete. When a heavy storm hits that baked surface, the water simply can't penetrate. It bounces straight off, strips away topsoil, floods patios, and runs down the drains, leaving your plants just as thirsty underneath. If we want our gardens to actually recover from a summer of extreme heat, we need to do a bit of prep before the rain arrives.”

4 Steps to Prep Your Garden for Incoming Rain

1. Brew a chamomile 'calming tea' for heat-shocked pots

After enduring constant hot spells, container plants are extremely vulnerable to fungal attacks the moment rain hits dry foliage and roots. Before predicted downpours arrive, brew a strong bucket of cheap chamomile tea, let it cool completely, and pour it around the base of your potted plants. 

Chamomile is a natural, mild fungicide rich in tannic acid, it acts like a stress-reliever for the root system, preventing 'damping off' and root rot when cold rainwater suddenly floods the container.

2. Crack the surface before downpours arrive

Get out into the flowerbeds with a hand cultivator or fork and gently scratch up the top inch of hard, baked dirt. On crisp, brown lawns, spike the ground with a pitchfork every few inches. 

Creating these small fissures breaks the soil's surface tension so incoming rain sinks straight down to thirsty roots instead of sheeting off onto your paving. Also, whilst we had the dry periods, it would have been a good time to sharpen the mower blades to give a good clean cut to grass once it grows again.

3. Hold off on the fertiliser

The most common mistake after a prolonged dry spell is throwing lawn feed or fertiliser onto the garden the second it gets wet. Forcing sudden top growth on a heat-stressed plant overburdens its damaged root system and burns it. Give your lawn and borders at least two weeks of steady moisture to settle and recover naturally before you even think about feeding. 

Once the rains come, don't be tempted to cut it hard when it starts to grow again. Keep the length high and just top it off to aid recovery and reduce stress.

4. Trap moisture with immediate mulching

Timing is everything when it comes to mulching. The moment the rain stops and you’re sure the ground is thoroughly soaked deep down, lay a two-inch blanket of bark chips or garden compost over your borders. 

Mulching dry ground locks drought in, but mulching freshly soaked soil locks that rainwater in place for weeks, protecting your plot if another heatwave returns.
