August Garden Jobs for a Healthy Summer Garden
Do you find yourself saying “what can I do in my garden this month?”. Well, if that’s you we have you covered with our August garden jobs.
1. Deadhead Dahlias and other perennials
In order to maintain a constant display of blooming flowers, you should deadhead your perennials when the flowers begin to fade or have died. This encourages new growth, meaning you will have a colourful, flower-filled garden for even longer. At this time of year where so many beautiful Dahlias are in bloom, it’s worth putting the effort in to have them around for even longer.
2. Increase greenhouse humidity
Keep your greenhouse humid during the hot weather by increasing the water available for the warm air to hold onto. Simply pour some water over your greenhouse floor every morning to maintain a humid environment. If you notice a lot of condensation, or that all your plants leaves are very wet, that is a sign to lower the humidity levels as your plants could be at risk of disease.
3. Add support to any taller plants that are starting to flop
Last month’s weather was great for plants, with the mix of hot days and rain. So, it is likely that you will have tall border plants that have gone through a bit of a growth spurt. If you notice any that are starting to flop get some canes and string and prop them up to give them support as they continue to grow.
4. Collect seeds
If there are any plants in your garden you’d love to try and grow from seed next year try to collect their seeds this month. It will take a bit of constant watching, as seedheads can appear quickly and you want to catch them before they are dispersed. Pick your seedheads when they have changed colour from green, but before they open, and leave them to dry for a few days. Once you’ve collected your seeds, you should store them in an air tight container until you are ready to plant them.
5. Increase the amount of water you give your plants
With the heatwaves we are experiencing this summer, it is important to remember to up the water you give your plants, but leave the watering to the early morning and late evening so you don’t scorch the leaves.
6. Fill up bird baths regularly
Alongside your plants, make sure your birdbaths are full of water this month, so your garden creatures don’t suffer in the heat and they have a nice place to cool down.
7. Keep on top of weeds growing
Hot days followed by storms can mean that weeds have the opportunity to thrive in your garden. Keep on top of them by removing them from the root when they start to appear. By catching them early it means your plants won’t be fighting for water or nutrients so, they can grow better.
8. Mow your wildflower meadows
Wildflower meadows are a beautiful addition to your garden if you have an extra bit of space. Wildflower meadows help to attract wildlife and insects to your garden, as well as improving soil health. They’re particularly beneficial to wildlife in urban areas, where sources of Perfect For Pollinators plants may be more sparse. August is a good time to finally mow your wildflower meadow as most of the flowers will have scattered their seeds and by mowing you are helping to disperse these seeds around the rest of your meadow.
9. Give your hedges a final trim of the season
It is almost the end of the growing season for many hedges, so take some time this month to dig out your hedge trimmer and give your hedges a final trim of the season. By trimming them now they will be able to grow into their shape slightly, leaving you with tidy, well-shaped hedges for the rest of the year.
10. Start thinking about the autumn perennial plants you’d like to add to your garden
Sometimes we can think that autumn means the colour in our gardens will have disappeared, but that isn’t the case. You can add a wide range of colours to your autumn garden using some of the following plants:
- Heucheras – Perfect for year-round foliage colour.
- Dahlias – A firm garden favourite with a wide range of colours and styles, so there is something for everyone.
- Ornamental Grasses – These are great for filling out borders. Why not try our favourite Imperata Red Baron.
- Sedums – Flower through into autumn with wonderful colours.
