Protecting your garden in the dry and hot weather

Blue sky

Hot weather and lack of rain have accumulated into a perfect storm of plant-threatening drought that is having an effect on crop supplies of lettuces and cabbages to our supermarket shelves.

So what does this mean for you?

Some edible plants and flowers rely on growing in warm conditions but not hot conditions. Hot conditions can cause heat stress and mean plants are more likely to set seed prematurely, sacrificing flower displays and viable crops. 

Time to take action!

Whether you are growing flowers, vegetables or herbs – erratic watering (or lack of watering full stop) have a dramatic and detrimental effect on your plants – their colour, their performance, their longevity.

Each of our water-maximising tips below highlight whether it’s a simple solution, applicable to flowers or edibles (including fruit and vegetables) plus the price range for your peace of mind.

Recycle bath & cooking water - Good for flowers, vegetables, lawns, roses & shrubs

An easy solution costing up to £15

Yes this seems obvious, however we think we have found the best way to use your old bath water. Flopro has a collapsible 2 in 1 plastic bucket & watering can. When we trialled it, due to its soft plastic the bucket did not scratch the bath surface, something most rigid buckets will do.

If you can reuse your cooking water (once it has cooled) it also has the benefit of having some trace minerals within the water.

Also don’t forget to wash all your fruit and veg in a bowl where you can re-use the water in your garden afterwards. 

 

Water Retaining Gel - Good for flowers, vegetables & lawns

An easy solution for under £5

Water retaining gel is a tiny polymer ball. Mixed into compost for containers or dug into borders when the ground is watered the gel absorbs up to 400 times its own weight in water molecules. They then release the water back to your plant roots slowly ensuring your plants have a constant water supply. A fantastic watering solution over the holidays and to supplement watering with the hose and the watering can. You can also use automatic watering spikes, the water is drip fed directly at the roots so there is no evaporation. As the bubble heats up the pressure inside releases more water. Another solution is to use a Bag & Drip Irrigation Kit as this will be great at preventing plants drying out during the day, especially bad for tomatoes and potatoes where uneven watering can cause fruit to crack and split.

 

Sphagnum moss - Good for hanging baskets, pots & containers

An easy solution for under £10

Moss is fantastic at holding water. It’s light and airy and has a structure that creates little reservoirs of water around the roots of the beautiful flowers in your hanging basket. Sphagnum moss is easy to mould around the side & top of baskets and containers and allows you to save on constant watering.

 

 

Plastic pots & plastic window boxes - Good for flowers, vegetables, roses & shrubs

An easy solution from £5

By choosing pots made from plastic as opposed to terracotta you can really reduce your need to water. The vast amount of sizes, colours and styles mean that whatever your taste there is something to suit your budget. Plus if you choose a pot with a self-sufficient self-watering reservoir you can reduce your watering regime even more. For the traditionalist the faux terracotta Festanato range is a real winner.

Rootgrow Mycorrhizal Fungi - Good for flowers, vegetables, roses, shrubs & trees

Under £10, some skill is required

Improve the root-growing abilities of your favourite garden plants like roses and rhododendrons by adding this fungi mix. In essence, the fungi increases the root zone area of your plants. The greater this area the more water these roots can access from far and wide. Sprinkle the fungi mix into the bottom of the planting hole before watering and planting up.

 

 

Weeding - Good for flowers, vegetables, lawns, roses & shrubs

An easy solution from £5

A simple solution which you hopefully already have the tools for. Remove the competition for water by getting rid of weeds surrounding your prized plants as well as the weeds in your lawn. We really like Kent & Stowe’s loop weeder.

 

 

 

Dig organic matter into your soil - Good for flowers, vegetables, lawns, roses & shrubs

An easy solution from just £5

A compost rich in any type of organic matter, will when dug in to your vegetable plot or ornamental plant borders automatically absorb and hold onto the moisture from your watering. If you have a compost bin, now’s the time to see what you can take and start digging in.

Regardless of whether you are protecting vegetables or ornamentals we really like Gro-Sure’s vegetable growing compost. Rich in organic matter and slow release fertiliser it will benefit any plant and really holds onto moisture in the soil. You can also try using GroSure Easy Container Compost which is designed with water storage in mind.

 

Cover any bare soil - Good for flowers, vegetables, lawns, roses & shrubs

An easy solution from £10

Once you have dug in as much organic matter as possible, cover the bare soil with bark or ground cover. It not only suppresses weeds it also helps reduce moisture loss. Which means that you should reduce your need to water. We like Gro-Sure Smart Ground Cover which is new on the market this year. Made from wood fibres that naturally lock together we found that when watering the bark had less chance of being moved apart.

 

Protecting your lawn

Easy to quite complicated task starting from £10

It’s important to know that it takes a severe drought to actually kill off the lawn. That said you will have to accept that you are going to end up with a brown lawn during a summer drought and ornamental lawns using fine seed grass will suffer more than a general lawn seed or turf.

Mowing

Allow your lawn to stay as tall as possible, so raise the height of your mowers cutting blades. Also allow the clippings to fall back into the grass but ensure you have small / fine clippings, large clumps will smother your grass. Try not to mow in full sun.

 

 

 

Feeding

Nourishing the lawn prior to a drought can be a big benefit. Westland’s new organic safe lawn suppresses weeds, prevents moss, feeds the grass roots and also adds small amounts of grass seed to your lawn. 

 

 

 

Weeding

It’s important that you do not use lawn weedkiller when the lawn is stressed from a lack of watering. If you are happy with a non-organic solution for clearing weeds from your lawn, we’d recommend Westland’s Resolva Lawn Weedkiller. We recommend spring and early summer applications rather than autumn and winter applications. Never apply in the autumn if your lawn has had insufficient rains during the summer months.

 

Right plant, right place

An easy solution from £10

You need to be looking for the following key words, Mediterranean, low maintenance and also drought tolerant. These type of plants can survive on a lot less water when faced with dry conditions.

Scan our websites for bay trees, olive trees, lavenders, citrus trees and basil which are all naturally built to cope with periods of drought and thrive in full sun, putting on lots of flower colour even if you have the shallowest or driest of soil. Also don’t forget that almost all wildflowers are drought tolerant too.

 

Plant your flowers closer together - Good for flowers

An easy solution

Planting flowers close together gives multiple benefits. Better colour concentration, plus flowers in close proximity to one another provide more humidity around the leaves which gives a source of moisture to your flowers 24-7. Also denser leaves, means less sun on your soil which means less water evaporation. Try growing bedding plants as close together as 4in (10cm) apart in all directions for impact and water-saving.
