Green roofs: the only way is up

So your flowerbeds are full, the greenhouse is overflowing, there’s no more room for pots on the patio and every vertical surface in the garden is covered in foliage. How do you find space for new plants and enjoy the thrill of a fresh challenge in the garden?

The answer? A green roof bin store. As well as screening your unsightly plastic monstrosities from view, a custom-made green-roof bin store provides the perfect place to grow attractive, scented and edible plants for instant kerb appeal and a lasting first impression. Here’s how I designed mine…

How to build a green roof bin store

Nic’s bin store was inspired by this version in the RHS Community Garden at Hampton Court.

Inspired by the RHS Greening the Grey Community Garden at Hampton Court Flower Show back in 2015, I fell in love with their fabulous bin store with a thyme and wild strawberry green roof.

Working with a local carpenter, I created my own version of a green roof store that would accommodate two bins and give me room to grow plants on the top and up the trellis sides. I also planned a selection of different sized holes in the side panel for solitary bees. Over the last three years these holes have been used regularly. I often see bees going in and out with their mud pellets blocking the holes.

Once the bin store was complete, I lined the top with heavy duty plastic sheeting and covered this with 20mm gravel to improve the drainage. I left a hole at the back through which the water could drain down a hose to the ground and screwed an upturned tea strainer over the hole to prevent blockages. I filled the rest of the top with a low-nutrient green roof substrate based on crushed recycled brick and green waste compost – and I was ready to plant it up.

Best plants for a green roof

The bin store is in full sun, so I chose plants that prefer sunny, well-drained conditions like alpines, succulents and herbs. The sunniest side is filled with lemon thyme (Thymus x citriodorus) and Thymus ‘Silver Queen’, salad burnet (Sanguisorba minor), French tarragon (Artemisia dracunculus var. sativa) and winter savoury (Satureja montana). All have thrived and they are self-seeding on the roof, so I know that the conditions are right for them. Thrift (Armeria maritima) has also done well and self-seeds all over, but perhaps the most successful planting has been the succulents. I positioned them at the front so their delicate foliage and tiny flowers are at eye-level when I pass to empty the bins or get in the car.

In the spring, Sedum ‘Cape Blanco’ and Sedum spathulifolium ‘Purpureum’ have small starry yellow flowers and Saxifraga ‘Buttercream’ adds its soft milky flowers to the mix. During the summer months, Sempervivum arachnoideum sends up pink starry blossom spikelets and I grow annual climbers up the sides of the bin store – this year the trellis has been covered in the apricot shades of Thunbergia ‘African Sunset’ mixed with the deep purple bells of Rhodochiton atrosanguineum.

More than just a screen

The bin store has been a practical success, but it’s added more than just a screen to the garden. I’ve been able to include plants which struggle in the shadier conditions of the back garden and bring some miniature succulent treasures into the limelight.

Although sedum matting is a great way to cover a green roof, if you’re hankering after extra growing room I’d encourage you to be ambitious and experiment with a range of species – perhaps herbs, alpines and different succulents, or even an elevated wildflower meadow – the sky really is the limit!

Grow Your Own.

It’s not too late to grow potatoes now with plenty of late varieties available, I even start potatoes off in September to have new ones on Christmas Day.

Potatoes do best on open sunny ground, but I grow mine in deep sacks. They will grow in an old plastic or metal dustbin so long as there are sufficient drainage holes. Place 4 inches of compost in the bottom of the sack, add three seed potatoes, sprinkle over some fertiliser, (according to the packet directions) then cover with another 4 inches of soil. Each time the stalks grow through the soil, add more compost (earth up) until the sack is 3/4 full. Water regularly. Potatoes do not like to dry out, but neither do they like to sit in wet soil.

Once the potatoes have flowered (12-16 weeks) cut the stalks to soil level, then dig up the potatoes after ten days.

Leave them to dry then wash the skins, dry again and store in a cold dark place.

Inspiring kids to love the garden

Discovering the wonder of nature is a lifelong journey.

My own childhood memories of high summer are filled with light, scent and taste: my dad’s mesembryanthemums with their candy-coloured faces following the sun, honeysuckle perfume saturating the evening air and summer raspberries still warm as I popped them in my mouth.

I was lucky enough to spend my childhood summers playing in a third-of-an-acre garden with apple trees, flower borders, a vegetable plot and a wild area where I was often to be found, at the top of the Scots pine, with an apple and a book.

Modern gardens are getting smaller, and more families are living in urban settings, often with only a balcony or window ledge for outside space. So how can we engage today’s youngsters with plants, nature and the outdoors, especially during the long summer holidays?

How to create a natural den

The Scots pine canopy of my childhood was a special private place – the kind of secret outdoor space that many children like to create around themselves. But there are no mature trees in our small garden, so I planted a willow den for my kids as a place where they could be alone with nature. Willow dens are created by using whips (young, thin willow rods) that will root when driven into the ground and kits can be purchased from specialist suppliers to train into wigwams, domes and tunnels. As they mature, the foliage cover develops and entirely screens the centre of the den from the outside.

My children loved their den. We have fond memories of eager faces appearing from the entrance playing ‘peepo’ and small hands thrust through the foliage to wave at us from within. Willow likes fairly damp ground and our den finally perished after six years as the soil is a little too dry, but in ideal conditions these dens will last for years.

How to sow the magic of seeds

There’s nothing like the magic of watching seeds germinate and develop bright blooms for flower pressing or tasty salad leaves. Getting kids involved in growing from seed can be the start of a lifetime’s fascination with gardening and it’s easy to grow plants like marigolds, lettuce leaves or tomatoes in a container or on a windowsill. If you haven’t sown seeds with the kids yet, it’s not too late. French beans, radishes and beetroot seeds can be sown as late as July, or alternatively you can buy tomato, courgette and pepper plants which will bear fruit throughout the summer.

This year we’ve been growing nasturtiums, calendula, cherry tomatoes and peas so the children can make simple salads garnished with edible petals. We also pickle the nasturtium pods as an alternative to capers – a peppery addition to pasta and pizza. As they eat their way through the vegetable bed, the kids are definitely developing more adventurous tastes and learning about where their food comes from.

How to get up close with wildlife

Nature is filled with beauty when you take time to observe.

There’s a whole world in even the tiniest patch of grass or flowerbed: spiders, woodlice, ants and hoverflies are all easy to spot when you stop and observe the garden close up. We’ve had tawny mining bees in our small lawn this summer, exciting visitors that we’ve been watching as a family and the kids have a magnifying pot so they can examine the patterns on a snail shell or the detail of a ladybird’s wing.

A container in a sunny spot filled with lavender, salvia, agastache, dwarf buddleja or herbs like oregano and thyme will encourage pollinators into the garden or onto a balcony. Putting food and water out for the birds adds another dimension to the garden, allowing kids to learn more about local wildlife.

One of my favourite garden moments was watching fledgling great tits emerge from the bird box by the shed with my five year old son. He’d watched the adults feeding their young for days and was fascinated by the way the fluffy fledglings kept poking their heads out of the hole before finally flying the nest. When the last great tit left the nesting box, to our amazement, it landed briefly on my shoulder and then headed off over the shed – this kind of experience is a fabulous way to ignite a child’s interest, creating the gardeners and naturalists of the future.
