We don’t know yet what kind of August we’re going to get – hot and dry or wet and humid!
Our gardens are now in full summer mode – and if you are growing your own, you will be enjoying the best of your harvest.
Hopefully we’ll get plenty of sunny days in which to lie back and enjoy our gardens this month – but there will still be some little tasks to get out and do in the garden.
Here are our gardening tips for August:
Keep deadheading flowers to prolong the display
When a flower is past its best, simply snip it off (cutting as far back down the stem as you can, until you meet another stem, a leaf or bud). It’s important to get rid of the dead flowerheads as it encourages the plant to produce many more flowers, and for longer, so just a quick trim every few days will bring the best out of your plants. This works really well for dahlias, roses, cosmos, geraniums, lupins and more.
A useful tip for dahlias – it can be difficult to tell the new buds from the spent flowers. Those which are still to flower are a nice round shape – whilst those which are done are slightly pointed – like in the pictures below.
Water and feed
Keep watering pots and hanging baskets – and feeding regularly with tomato feed (weekly or fortnightly). Sometimes when we get lots of rain it’s easy to forget that pots and baskets might still need watering. If we are lucky enough to get dry, sunny weather, make sure you top up bird paths and ponds regularly, too.
Keep on top of the weeding
At this time of year, the weeds are growing prolifically, as well as the flowers! There’s always another one popping up just when you think the job is done. It can be a bit frustrating but nothing beats the satisfaction of a freshly weeded bed – even if it is short lived!
Start your post-flowering pruning
Prune back climbing and rambling roses once they finish flowering and trim lavender plants to help them keep their shape. It helps to know what type of lavender you have before cutting or trimming it. English lavender can be cut back by two thirds in the second half of this month, and you can even cut into the bare wood. It will soon begin to regrow and the new shoots will have time now to develop and harden up before winter. But if yours is French or Spanish lavender, never cut back hard and never into the bare wood. Just a gentle trim to help it keep its shape is all that’s needed this month.
Sow some seeds for next year
There are some flowers you can sow from seed now for flowers in spring / early summer next year – such as cornflowers, calendulas, forget-me-nots, California poppies. You can also sow more seeds for growing your own and eating this year – including lettuce, rocket, spring onions, radish and more.
Loads to do if you’re growing your own
If you are growing your own there’s lots of harvesting to do – carrots, runner beans, cucumbers, courgettes, beetroot, potatoes & more. I’m certainly hoping my tomatoes (of which I seem to have hundreds of green ones) ripen up very soon. Keep an eye out for pests on your plants – if necessary cover plants with netting or fleece. If you’re growing sweetcorn, like I am, keep watering and feeding them with tomato feed – the same goes for pepper, cucumber and aubergine plants once they start to form fruits. If you are growing tomatoes, keep an eye out for tomato blight – removing and destroying any affected plants immediately to stop it spreading. The signs to look out for are small brown marks on the leaves, which enlarge as the blight takes hold. Eventually brown spots will appear on the stems and branches – they’ll then turn to a much darker brown/black.
Look after your lawn
At this time of year, if your lawn is looking a bit brown and sizzled, ty not to worry because the autumn is bound to bring plenty of rain which will soon green it up again. Turf is actually a lot hardier than you might think. Resist the temptation to feed it now because it will generate new growth which will be easily damaged by autumn conditions. You can think about raising the cutting height of your lawn mower now as the growth will begin to slow.
August is a good time to give hedges a final trim and shape for the year. Pick a nice cool day for this hot job! If you don’t fancy doing it yourself, why not see if any of the gardening companies in our Local Directory will do it for you?
Keep vigilant for the dreaded Lily Beetle
Your lilies may have well finished flowering by now but as the foliage dies back you still need to keep an eye out for the naughty Lily Beetle on them… especially their sticky brown larvae underneath the leaves. I have to confess I took my eye off the plants after they finished flowering – then to my horror discovered one of them had become an absolute haven for these little blighters! I wipe it off the larvae with kitchen roll, crush it and bin it.
