My mellow yellows: He has glorious roses of every hue in his garden

For the past month my cottage garden has been filled with flowers from more than 50 different varieties of shrub roses. 

These are of every hue from the pure white of ‘Madame Hardy’ to the almost purple ‘Cardinal de Richelieu’, though the dominant colour is pink in every shade. But I have one border with only yellow and apricot roses and another part of the garden, The Mound, where only soft yellow, white and pale-blue flowers are planted. 

This also features three different yellow roses.

In fact, I came to yellow by way of apricot. Apricot is a rare colour in plants, and the peachy tones of pink, orange and yellow combined tend to veer one way or the other without hitting that exact spot in the middle. 

British gardening expert Monty Don, shared his advice for blooming roses throughout summer. Pictured: Monty with his ‘Crown Princess Margareta’ roses

Although there are scores of pink roses I adore, I have yet to find a distinctly orange rose that I like. Roses of a strident yellow are not my thing either. Luckily, there are a few delicious peachy apricots and even more lovely soft yellows.

I like roses with loose, blowsy petals rather than the sugar-icing formality of hybrid teas. 

Over the past 40 years David Austin roses have combined the romantic looseness of old roses with the repeat-flowering qualities of hybrid teas and other more modern varieties to produce some of the best garden roses you’ll find.

The most famous yellow rose is ‘Graham Thomas’, bred by David Austin and introduced in 1983. 

Ask Monty

Q I have a mahonia planted close to my bungalow. Will the roots damage the building?

Carol Blackburn, Northamptonshire

A People get very anxious about this but it is not a problem save with certain trees like large willows or ash – even then, only on certain soil types. Relax and enjoy your mahonia!

Q For my compost bin, I’ve used woody material layered with soft material, a compost accelerator and turned it all, but nothing works. What’s wrong?

Tony Vardy, Derbs

A Do not build the compost in layers but mix it all up as you go. Fill the bin to the top, leave it for three weeks, then turn it. Repeat three or four times. Compost is made almost entirely by bacterial and fungal activity. Bacteria need oxygen, water and food. A so-called accelerator is just a fancy form of the nitrogen found in garden waste and kitchen scraps. So, mix it all up well, and turn, turn, turn!

Q We have a wisteria growing up a wall which is several years old but has never flowered. Why?

Pam Boon, West Sussex

A Wisteria can take up to eight years to start flowering. If a mature wisteria ceases to flower it’s because it’s being fed too much nitrogen – which encourages leaves – or it’s been wrongly pruned. Prune now, cutting back unwanted new growth to two or three leaves. New shoots next spring will carry flowers.

It is quite a rich, almost egg-yolk yellow with a lot of noisette roses in its parentage that gave it toughness as well as the clusters of flowers that characterise noisette varieties. 

One of the best-known noisettes is ‘Madame Alfred Carriere’, which remains one of my favourite climbing roses. ‘Graham Thomas’ is available as a climber, too. 

However, my two favourites that I grow here are ‘The Pilgrim’ and ‘Vanessa Bell’, both also David Austin roses and both rather subtle. 

‘The Pilgrim’ was introduced as a medium-sized shrub but is now reckoned to be better as a climber, and I grow it trained up wooden wigwams. It has a delicious fragrance and is touched with a hint of pink in its massed primrose-yellow petals as the colour fades.

‘Vanessa Bell’ is a recent introduction and, I think, a real winner. The flowers are very pale yellow, held in large clusters and can be grown equally well in a container or a border. 

We have it growing on The Mound, where it is a modest star. Also growing there is the yellow rambler ‘Malvern Hills’. 

As rambling roses go it is restrained and able to be accommodated in a small tree, pergola or even fence and – extremely unusually for a rambler – its lovely, small, multi-petalled, lemon-coloured flowers repeat throughout the summer.

Of the apricot flowers, the best, for my money, is ‘Crown Princess Margareta’, which has delicious fragrance and will cope with quite a lot of shade, so is recommended for almost any garden. 

‘Charles Darwin’ can appear almost primrose yellow, through shades shifting from bright yellow to apricot and then on to orange. The warmer and sunnier it is the paler it becomes, so in our increasingly wetter, more overcast recent summers it almost falls into the apricot category.

As with all roses, the secret to keeping these blooming for as long as possible is to deadhead daily, cutting right back to just above a leaf to stimulate sideshoots that will carry fresh flowers. 

They all take a rest at the end of July but will start flowering again from late August until well into autumn. 

THIS WEEK’S JOB: FEED CONTAINERS

Monty explained that plants should be fed weekly to perform at their best all summer

Monty explained that plants should be fed weekly to perform at their best all summer 

To perform at their best all summer, plants in containers need a weekly feed. Ensure it’s high in potash for root and flower formation, but not high in nitrogen which promotes soft foliage. 

Tomato feed or liquid seaweed are good, but make them no stronger than what the pack says.
