Falling leaves aren’t the only things that add glorious autumn colour to your garden, says Monty Don

Berries are the surprise gifts that light up autumn. A berry is defined as a fruit with the seeds wrapped in pulpy flesh, which attracts birds and animals to eat them, thus spreading the seeds. Grapes are berries, as are tomatoes, bananas, cucumbers and watermelons, while – technically – raspberries, strawberries and blackberries are not. But that is botanical nicety.

The berries that are probably the brightest thing in our gardens right now are the ornamental fruit of trees, shrubs and climbers such as roses, hollies and hawthorns, although there is a wide range of plants to choose from that will produce them. 

As berries are produced from a plant’s flowers, and will appear as the blooms have faded and fallen, species that flower before the end of June tend to produce a better berry display in the autumn because the little orbs, like all fruit, need time and sunshine to ripen.

Monty suggests autumn berries could add some much needed colour alongside falling leaves in your garden. Pictured, Monty holding hip-laden Rosa ‘Scharlachglut’

The berries produced by roses – what we call rose hips – appear in very diverse forms, from great tomato-like ones on rugosa shrub roses, to gobstoppers on Rosa ‘Scharlachglut’, oval aniseed balls on dog roses, black ones on R. pimpinellifolia and small dangles of orange on R. cantabrigiensis and R. willmottiae.

R. moyesii remains one of my favourite roses: it produces wonderful single crimson flowers that speckle large upright bushes, but the hips – orange flagons, long and waisted like gourds – are better still. 

The very best berries in my garden, however, belong to a rambling rose called ‘Edith’. I have this growing up through a standard ‘Chivers Delight’ apple tree and for a few weeks in October the combination of the rather small (but delicious) orangey-red apples and the mass of orange hips is just wonderful. 

In fact, the hips of ‘Edith’ last for ages, well into the new year and long after every apple has fallen.

ASK MONTY

Q. My Bramley apple tree blew over last year, but shoots have been coming off it ever since. I’ve grown two on – will they become trees?

Angi Williams, Somerset

A. The shoots are branches from the tree so there is no reason why you could not select one to make a new vertical ‘trunk’. Alternatively, you could accept that everything has a lifespan and it is time to plant a new apple tree!

Q.Please can you tell me if coffee grounds are beneficial to plants?

Sandra Lewis, Lincolnshire

A. Coffee grounds tend to be used as a slug deterrent, though their efficacy is limited and there’s evidence they harm growth by reducing bacterial activity. I’d add them to the compost heap instead.

Q. I had a good crop from my Victoria plum this year, but the leaves have now turned silvery and half the tree appears dead. What can I do?

Mrs Hilliard, Hants

A. This is probably silverleaf, a fungal disease whose spores enter the tree through wounds (often pruning cuts between September and May, whereas in mid-summer the tree produces a gum that stops the fungus entering). I’d cut down the tree and not replant a plum within 10 metres of the site.

Last year I planted a little bed specifically to produce berries, both as a decorative display and to provide food for birds. This backs onto a hedge dominated by hawthorn, whose berries are the mainstay for birds, especially winter visitors such as fieldfares and redwings. 

To this bed I’ve added a number of shrubs chosen for the variety and range of their berries. The most unusual is Callicarpa bodinieri var. giraldii, an unspectacular shrub for most of the year but which produces incredible berries that are a gleaming, almost metallic purple.

Another unusual berry belongs to Clerodendrum trichotomum var. fargesii – they are bright blue and develop from white flowers that open from mid-summer. It does best in a very sunny spot – mine is partly shaded – and is not fully hardy so I give it a very thick mulch in autumn to protect the roots from hard frost.

Much tougher is Viburnum opulus ‘Xanthocarpum’, which has lace-cap flowers in spring that convert into gold and yellow berries. It is very adaptable, growing in full sun or part shade and tolerating most soils as long as it is not waterlogged. 

Pollinators love the flowers as much as birds do the fruits. I also planted another viburnum, the evergreen V. tinus ‘Eve Price’, which produces its pale-pink flowers in very early spring, and these then become blue-black berries.

Finally there is Leycesteria formosa. It produces claret-and-white flowers from mid-summer and these then become burgundy-coloured berries in autumn, which are gobbled up by the blackbirds. It looks exotic but is easily grown, adapting to sun or shade and almost any soil. 

MONTY’S PLANT OF THE WEEK

Yellow azalea (Rhododendron luteum)

I know this plant is confusingly titled – its Latin name is rhododendron, the English one azalea – but it offers one of the garden’s most magnificent autumnal displays as its leaves turn a brilliant cherry red, with bright pink highlights and plummy depths.

It’s happiest in acidic soil and cool, moist air, so don’t let it dry out (but avoid waterlogging too) and pay particular attention to watering it regularly from late summer until leaf fall to ensure the buds set properly.

This week's plant of the week is Yellow azalea (Rhododendron luteum) which he says puts on an impressive autumnal display

THIS WEEK’S JOB: STORING DAHLIAS

Cut back material above ground, leaving a few inches of stem. Lift and place the tubers upside down in a dry spot under cover for a day. 

Clean off soil and slugs. Store in a tray packed with potting compost, vermiculite or sand. Keep cool, dark and dry. Lightly water if they shrivel.
