This time of year is my favourite in the garden. With the long summer days behind us the light from the sun is not nearly as harsh as it was in June and July. The flowers in the garden are still blooming but with the longer shadows of early evening, it gives them more depth. I wish I could keep this month in the garden all year round! But as that is not possible I try to keep the rich colours of the garden for as long as possible. How to do this you wonder?
I dead-head many of my flowers, to keep them going. By dead-heading you are tricking the plants into believing they are still young. When you allow your plants to seed, they receive a chemical message informing them they no longer need to produce blooms and now is the time to stop. By dead-heading them they continue to enjoy youthfulness and produce their gorgeous blooms for a while longer. Of course this does not continue indefinitely, but it does provide you with colours until the end of the month.
Which plants can be dead-headed and which are best left to seed? I have always found my Penstemon ‘Strawberries and Cream’ will continue to produce its flowers in September. With a gentle dead-heading I continue to enjoy the pink and white flushes of colour. Other plants include Phlox paniculata ‘David’ and Pennisetum alopecoroides.
To dead-head softer stemmed plants, all you need to do is nip the flowers between thumb and forefinger once the flowers are finished. This will work for geraniums, petunias, cosmos and chrysanthemums.
However, some plants need a little more encouragement and to dead-head you will need to get the secateurs and cut back to the stem to the next shoot down. This applies to roses and dahlias; my Rose ‘Racquel’ has responded well to this and is still happily flowering.
There are plenty of my plants that I have not dead-headed, because they do not respond too well to it. Poppy ‘Bridal White’ is having its last flush of flowers and then it will be going to seed. The seed heads create an unusual backdrop for the remaining flowers in my garden. I am also leaving my Nigella ‘Delft Blue’, the seed heads are a show stopper all of their own. The few grasses I have such as the Verbena bonariensis are also going to seed. The insects really like living here and I don’t want to disturb them while they are happy!
Speaking of happy, don’t forget to let your Fuchsia FUCHSIABERRY go to seed, they will go on to provide you with an abundance of berries for jams and puddings. They are delicious…
So there you are, a bit more work and you have a lot more flowers.
I have worked for Thompson & Morgan for nearly four years. In that time I have learnt lots about gardening, but consider myself very much a novice. I have started growing veg on a colleague’s allotment and also growing windowsill seeds such as Salad Leaves and Rocket. I love gaining more knowledge about horticulture and am lucky enough to work here.
My magnolia was cut back after its second show of flowers now the Susan is in bloom again is this normal for time of year?
Hi Anna, thank you for your query. I have spoken to our horticulturalist who has said it is not uncommon to get a second flush. You must be doing something right! Send a picture on Facebook if you would like. We love seeing great images from our lovely customers. Take care, kindest regards, Wendie
