This guide on how to plant Summer Flowering bulbs will have your garden blooming right on time for the upcoming season. Planting bulbs is a super easy way to make your garden ready for summer. Whether you are aiming to show off some beautiful boarders or create a dynamic display with pots, this guide will show you how!
The best time to plant your Summer Flowering bulbs is during the season before – Spring. Summer bulbs need warm weather and warm soil to grow which makes April and May the best time to start planting if you want your flowers to bloom on time.
Step 1: Check the size
To ensure that your bulbs grow correctly it is important that you make sure you know the size of the bulb. As they need to be planted at two to three times their depth, ensure you dig a hole wide enough and deep enough for the bulb to fit.
Step 2: Spacing
When figuring out how to lay out your garden, ensure that the bulbs are spaced out at least twice the bulbs own width apart. Then place the bulbs in the hole with the tip or shoot facing upwards towards the sky. Replace the soil and firm. Be careful not to tread too heavily as this could damage the bulbs.
Step 3: Water
Water your plants straight after planting. Then make sure they are watered regularly, but allow the soil to dry in between watering.
Step 3: In the green
Don’t forget about those boarders! Remember to plant your pot-grown bulbs in the desired boarder position for them to flower. Make sure the hole is the same depth as before but deep and wide enough to allow the roots to spread.
As most bulbs are acquired and planted when dry and dormant, plant them as soon as possible. If left in storage too long they may flower poorly.
Regularly check that the bulbs are healthy and be on watch for any pests including slugs, snails and squirrels. Also, keep the area weed-free to ensure your plants are taking in as much nutrients as possible.
For a display: plant in groups of at least six to create a wonderful display. The more plants the better!
Dahlias are an ever-popular choice for many a summer garden. Their easy-to-grow tubers produce phenomenal displays of colour and texture in a range of styles throughout the season. However, if you’re new to gardening, you may be wondering how to plant these beauties.
Planting dahlia tubers is a straight forward process, perfect for those with less experience. With their beauty and effortless maintenance, it’s easy to see why they’re a horticultural favourite.
Why Choose Dahlias?
Dahlias are easy to grow and suitable for gardeners of all skill levels. These blooms are fast-growing by nature and will flower in the first year and for many years to come (keep them stored and frost-free over the winter).
Dahlia tubers are versatile and will tolerate most types of well-drained, fertile soil or compost. They can be grown successfully in pots, tubs, window boxes and in borders.
They are a firm favourite due to the many different types, sizes, and colours available on the market.
New varieties are created each year. Once you’re hooked on Dahlias, you will always be able to find something new.
They flower continuously through the summer, right up until the first frost of the autumn.
They look fantastic as cut flowers, making any display a memorable one.
Before we move onto planting dahlia tubers, here are the main types of Dahlias. Each variety can be classified into several different categories, representing the main characteristics of the flower blooms themselves.
Anemone Flowering – Also known as Powder Puff Dahlias, these beauties produce unique flowers with double feathered central petals resembling a fluffy ball.
Cactus– A favourite for many years, Cactus Dahlias produce fully double pointed petals which turn backwards to create a tubular petal effect. Are sometimes referred to as Spiky Dahlias.
Dark Leaf – As the name suggests, the foliage on this variety is not the usual bright green that you see on your average Dahlia. They create an abundance of flowers through the summer, with each bloom appearing on darker (usually purple/black) foliage.
Decorative – Produces large, fully double flowers with rounded petals through the summer right up until the first frosts. A perfect choice for cut flower displays.
Dwarf– A range of smaller, more petite Dahlias which are perfect for the front of the border. They are prolific flowering varieties, look also great planted mixed in pots on the patio.
Dinner Plate – As the name suggests these are the largest flowers within the range, often up to as much as 25cm in diameter (see illustration below). Another popular choice as cut flowers.
Pompom – Love the unusual? Pompom Dahlias produce ball-shaped blooms that appear through the summer. Each petal has rounded tips and are curved upwards at the edges, and are available in plenty of colours.
Planting Dahlia Tubers
All our Dahlias are supplied as top quality dormant tubers which can be planted as soon as you receive them. The success rate from these dahlia tubers is extremely high. They are also an inexpensive way to create a large number of flowers from one plant.
Dahlia tubers should be planted 10cm deep in fertile well-drained soil, outdoors in spring when the frost has disappeared. They prefer to be in a sunny location and spaced at approximately 45cm apart. In areas where there is extreme cold, dig up dahlias and store in a cool peat over the winter. Apply a high potash fertiliser every few weeks in the summer to help growth and they can be dead headed when necessary.
Planting Dahlia tubers in Pots & Containers
Planting Dahlias in pots and containers is a fantastic way of brightening up your patios. Their unique colours and shapes will brighten any space, a perfect choice for gardens with less space to play with.
Once your tubers arrive safely in the post, they can be soaked overnight in a bucket of water to soak up as much moisture as possible.
When all signs of frost have passed they are ready to pot up, leaving plenty of time to grow a well-established root before the summer.
It is recommended to place some pebbles at the bottom of the pots before adding the compost to help with drainage, by ensuring the compost doesn’t block the drainage holes.
Fill in some compost and then add the tuber with the growing tip facing upwards.
Continue to fill in the rest of the compost to firmly hold the tuber, making sure the growing tip at the top is peeping out and is not completely covered. This is now ready to be moved to the patio or garden area, with access to as much sun as possible.
Water well after potting, keeping the compost moist but not waterlogged, as the tubers will rot. Add a liquid feed weekly during the growing season and provide some protection from slugs as they have a strong love for Dahlias.
If growing tall varieties, insert a cane to help with growth and to keep secure.
Very little pruning is needed with Dahlias. However, you can deadhead as flowers begin to fade.
Do you find watering the summer garden time consuming? With British summers getting hotter and drier, drought tolerant plants are the answer to growing a beautiful garden that can withstand the summer heat.
What are drought resistant plants?
Drought tolerant plants are specific varieties that are suitable for planting in dry conditions. They are perfect for planting in bright, sunny spots in the garden. Many drought tolerant plants have silver or grey-green leaves, their light leaf colour reflecting the harsh rays of the sun. Some have a coating of fine hairs on their leaves or stems, helping to trap moisture around the plant tissues.
Check out our favourite drought tolerant plants that will best adapt to the prolonged dry season.

Eucomis descend from South Africa and have an unusual pineapple shape. Their long-lasting flowers and attractive foliage are an exotic feature point of borders, pots and flowerbeds. Planting time is from February, if into pots and containers.
The general rule for planting bulbs is to dig deeper than the obvious. The usual guide is two to three times the depth of the bulb itself, however you will do less harm by planting too deep than too shallow. The other general rule is that bulbs need good drainage. The best way to achieve this is to mix grit into the general area or container of planting.
Many summer bulbs are ideal for growing in patio containers, especially tender species. These can then be lifted in winter and stored.
Step by Step:
Planting in borders:
Dig a hole wide and deep enough for your bulbs. Most bulbs require planting in a hole two to three times their depth.
Place the bulbs in the hole with their shoot facing upwards. Space them at least twice the bulb’s own width apart.
Replace the soil and gently firm. Avoid treading on the soil as this can damage the bulbs.
Planting in containers:
Dig a hole three times the bub depth, and plant the bulbs one width apart.
Water bulbs once after planting then regularly when in active growth. Reduce watering once the leaves die down through the dormant season.
If you bring pots of hardy bulbs indoors for flowering, put them in a sheltered spot outside as soon as flowering is over.

Verbena Bonariensis were dotted around almost every show garden on display this year. Whether as a background plant for a wild border or used as a centerpiece plant with their long stems, these beautiful purple flowers were definitely in the spotlight this year. A fantastic summer border plant with good pest resistance.
One of our favourite summer flowering perennials were heavily featured this year, the Echinacea. Also known as Coneflowers, they will flower from summer through late autumn, often still in flower as late as October. They make a bright and bold addition to the modern garden, look larger than life at the back of the border, and are a great way to attract butterflies and bees to the UK garden.
The beautiful giant blooms of Alliums took a center stage this year. Large varieties were spread all around the show, whilst smaller flowering varieties such as Allium Drumsticksand the half-spherical blooms of Allium Miami were featured in this year’s show gardens. An easy to grow and versatile range of plants that can work in any garden.
1. Pollinator Pals (Alliums,Achillea, Agapanthus)
Alliums, Achillea and Agapanthus were strongly featured in the show gardens at this year’s show. The show had a strong theme of pollinator-friendly planting and when it comes to looking after wildlife in the garden, these varieties are well-loved by bees and other pollinators.
Agapanthus are great showy plants with exotic looking flowers, Alliums are easy to grow, stylish plants with tall stems and large pom pom heads of flowers and Achillea are a stunning flowering herbaceous perennial with each flower head containing of hundreds of long lasting, tiny flowers. So, it’s easy to see how these beautiful summer contenders have been a popular choice this year.
Another big trend seen around the show gardens is creating layers of a variety of border plants. Ass seen with the brightly colours florals in the ‘Let’s Go Fly a Kite Garden’, the subtle contrasting tones in ‘The Perfumer’s Garden’ and the wild themed grassy border in the ‘Baroque Garden’.
Creating a layered garden soothes the eye while enhancing other aspects of the garden. Planting a garden in layers considers both vertical and horizontal eye appeal but also the aspect in which we view the area and seasonal interest. Planting a garden in layers will ensure that the highest plants are at the farthest eye point of the garden with medium sized in the middle and the lowest growing at the front.
Repeated patterns, colours, forms and textures throughout a border can create unique patterns in the landscape.
3. Harmonising Hostas
A key trend that was prominent in almost every show garden at this year event was Hostas.
Originating from China and Japan, Hostas are one of the best perennials for shade in the garden, grown in either pots, containers or borders. Renowned for the amazing foliage they produce and have become a common addition for the modern garden designer. Hosta plants are a great perennial plant which is often chosen for their attractive shaped leaves and summer flowers.
Hostas are ideal to add texture and colour to a garden planting scheme. They can be used to complement other plants by adding a contrasting look and style that enhances the overall interest and aesthetic of the scheme. There is a huge choice of varieties available to buy, covering all shapes, colours, and sizes for all tastes.
Ornamental grasses made their presence known in many show gardens this year. A range of herbaceous perennials and grasses were featured in ‘The Mindful Garden’, such as Festuca. The silvery needles of Festuca glauca were featured in the monochrome palette of the ‘Every Cloud has a Silver Lining Garden’, and long and varied grasses were displayed in the ‘Trail of Thoughts Garden’ to represent the fading of memory with colourful flowers giving way to a grassier and more muted landscape.
Grasses have long since proved their value in the landscape, moving from what was once considered a craze to one that is a solid cultural shift. As gardens have shifted toward lower maintenance and nature friendly, ornamental grasses have fit every bill that today’s gardener demands — while providing the contrast, texture and form that designers crave.
Who can forget the ever-changing blooms of hydrangeas. The use of beautiful fragrant shrubs were used for structure in a variety of the show gardens this year. The once overlooked hydrangeas of the past are now the trend setting plants of today.
With immense flower heads, Hydrangeas flaunt an old-fashioned charm that is hard to resist. Unrivaled in the shrub world for beautiful flowers, they are easy to cultivate, tolerate almost any soil, and produce abundant blooms. Hydrangeas are excellent for a range of garden sites from group plantings to shrub borders to containers.
