We have compiled some answers to some common questions about gardening in hot weather.
How do you keep your grass green in the Summer?
Don’t cut your grass too short
Your lawn will get stressed in hot weather and it also gets stressed when it is cut short. You can’t do much about the weather (especially if we do get a hosepipe ban), but you can keep your grass a little longer than you might otherwise have.
Keeping your lawn a longer length makes it a more resilient to dry weather – it encourages the plants to develop deeper root systems. The longer grass will also shade the soil more and keep the moisture in the Earth a bit more, all helping to keep your grass greener for longer. Other benefits to not cutting the grass as often or as short include: More time, more wildlife, more money!
What is the best time to water plants in hot weather?
Water your plants in the morning
The best time to water your plants in hot weather in very early in the morning. Certainly before the sun has had any chance to warm the day. This allows the water to soak into the cool soil and not evaporate back in the air. If you have to water during the day, go for as late as you can in the evening or when it is cloudy. Of course if a plant is looking particularly parched and on the edge of heat stroke then do water it, but drench it rather than give it just a little water. If it is a potted plant, soak it in a bucket of water (or pond) until the air bubbles stop rising to the surface of the water.
How do I garden with no water - say during a hose-pipe ban?
- Re-use Water
If you have plants that are particularly susceptible to drying out during dry weather, you can use the water from your sink, shower and bath to water them. As a couple of starters, we recommend putting a bucket in your shower to collect the water as it warms up to the temperature you prefer and catching the water that you use when washing fruit and vegetables in your washing up bowl. This clean water is easy to re-use in garden. Further steps would be to use the washing up water (just check the ingredients in your washing up liquid will not harm the plants) or to set up a grey-water system.
- Mulch your plants
As much as 70% of water can evaporate from the soil surface during a hot day. The best way to stop that is to add a protective layer of organic matter on top – known as a mulch. Mulching is one of the best strategies you can employ for keeping moisture in the soil, adding nutrients and suppressing weeds. Coarse bark is the type of mulch we prefer to use. A few key things to know about mulching; only put the mulch on when the soil is already damp (so after a good rain event), make sure you have removed all the weeds before you put it on and spread it to a thickness of 5 to 8cm.
- Collect Rainwater
If you have a water butt or other rainwater harvesting system you can connect a hosepipe to it and use saved rainwater to water your garden with garden hose or watering can. Thousands of litres of rainwater fall on your roof every year which is enough to fill even a very large water butt many times over. Water butts come in all shapes and sizes and can be beautiful too.
Rainwater Harvesting for use in the home, in agriculture, office and other commercial environments is becoming more popular. Storing rainwater for later use can reduce water and sewage bills and allow you to water a garden during a hosepipe ban with gentler rainwater rather than treated tap water. Using rainwater in a washing machine or in [...]
Upstream water attenuation is part of a range of solutions to flooding, even better if it can be combined with wildlife friendly gardening. In this first in a series of blog posts about Sustainable Drainage Systems (SuDS) we look at the role of Rain Gardens in Flood Mitigation. The term “Rain Garden” has changed over the years. Technically it has [...]
When local entrepreneurs Gareth and Pam Stephens wanted to include two self-catering log cabins on their caravan and camping site just over the valley from us here in Cardigan they had some decisions to make. A big part of ensuring that your campsite runs well is to make sure that people have everything they need at [...]
