Complete Guide: How To Plant Begonia Tubers

With the winter months coming to an end and spring on the horizon, you may well look to the garden and start plotting another year of beautiful borders and overflowing hanging baskets.

In recent years, Begonias have soared in popularity for their versatility and reliability. These colourful favourites will solve all your summer garden needs, from hanging baskets and window boxes to borders and pots. With such a shining reputation, its an easy choice to make but you may be wondering which variety is for you.

This week we’ll help you get a head start on that summer planning with our comprehensive guide to Begonias.

History

Although it has been theorised that Begonias have been around for thousands of years, the plants first got their name in 1690. The renowned botanist Charles Plumier named the plant after his colleague and friend Michael Bégon, a fellow plant collector.

Native to the slopes of the Andes, tuberous Begonia thrived naturally in the cool mountain temperatures and moist shade of the Amazon rainforest. Hundreds of years of propagation and hybridisation has given us the larger, more colourful and diverse Begonia. Nowadays we are spoilt for choice, with everything from giant, double flowering show-stoppers to unusual, fringed favourites.

Tubers

Tubers can even be stored over winter and reused year after year, making the Begonia plant excellent value for money. Preferring half-sun and rich, moist soil with good drainage, we recommend that Begonias are grown indoors first and planted outdoors only when all traces of frost have disappeared.

Growing Begonias from quality tubers helps improve results. We only supply the best grade tubers possible to offer you the best results. They are simple to plant, care for and the high level of results they achieve make them an easy choice when growing Begonias.

Begonia sizes are measured by the diameter of the tuber. The tubers are counted into breathable bags and carefully packed to be delivered to you. Many of our varieties are supplied either as standard size (3/4cm) great for mass planting or exhibition size (5cm+) excellent for large flowering displays. We always state the tuber size so please check the description before ordering.

How to Grow

You can follow some top tips for success with Begonias below, or watch our video series with Jeff for his sage advice on planting cascading Begonias for hanging baskets.

  1. You can start planting Begonia tubers from February onwards. Mix some good top-soil with one-sixth part of manure should form the basis. Once you’ve prepared the soil, add some leaf mould in a mix of 1 part leaf mould to 3 of loam and enough sand to make a fairly porous compost. Soot and bonemeal added to the compost will be appreciated.
  2. As soon as the shoots of the tubers are about 2cm long pot them up in 15cm pots and place them into larger pots as the roots reach the sides of the pot.
  3. Plant in full sun or partial shaded areas. The more access to sun, the more vibrant the colours will be.
  4. You can feed once every two weeks with a high potassium up until the blooms begin to fade.
  5. Make sure they are watered regularly during the summer and that the soil is not allowed to dry out. Begonias love moisture and will use up quite a lot during the hotter spells in the summer.
  6. Lift tubers after flowering has finished and the leaves have begun to turn yellow. Store in a dry, cool (but frost-free) location over the winter. Store in soil that is only a little moist and keep this a little moist over the winter (with irregular watering) to keep the tubers from drying out.

Gardening Jobs for June

Summer Bedding
If you held off planting in May, now is the ideal time to clear these plants out of your greenhouse and get your summer bedding and hanging baskets finished. There is minimal chance of frost even this far north so line your baskets, prepare the soil and use some organic compost to fertilize the soil. Ensure you water regularly particularly if the weather is warm and dry.

Hot weather protection

Hot and dry weather can be just as dangerous as the harsh conditions of winter for your plants. Recent dry spells mean watering is more important than ever. Don’t let all your hard work go to waste. Regular watering of pots and baskets is essential to maximise your garden show this summer. You should also remember to keep your greenhouses cool and prevent scorch with shading and ventilation.
Perennial Work
Prepare to tie up tall border perennials with support. Tall varieties such as Hollyhocks, Delphiniums and Lupins will need a little help and stakes can help prevent wind damage. You might also like to cut back early-flowering perennials such as Papavers as this will provide fresh foliage and possibly even a second flowering.

Protect fruit trees
Protect the newly developing fruit on your fruit trees from birds. This can be tricky as netting suggested last month for soft fruit, is not a viable option. We recommend using some of those unwanted DVDs or CDs in newspaper supplements by hanging these from your trees on string. The changing reflections of light created in a little breeze should keep birds away.

Keep everything tidy
The warm weather and increased sunshine means that weeds are popping up everywhere and can be an eyesore in your garden. Keep an eye on these particularly during dry spells and it will make your garden look much neater. You should also now be cutting the lawn weekly, pruning many spring flowering shrubs and trimming hedges into shape. For bulbs, allow foliage to die down naturally before cutting back to ground level. Keep any waste for your compost bin!
Lawn Care
If you’ve been lucky enough to get some relaxation time in the garden, you may have had furniature such as lounger out on your lawn. Be aware that this could damage grass and cause patches of yellow damaged lawn. This is easily prevented simply by moving your lawn furniture regularly. Keep up trimming your lawn regularly, including the edges, and apply fertiliser for a healthy looking growth.

Gardening Jobs for May

Summer bedding plants

Mid-to-late May is the best time to plant out summer bedding plants. Prepare the soil and use some organic compost to fertilize the soil ready for the new bedding. You do need to keep an eye on the long term weather forecast when doing this, as a late strong frost can put pay to your hard work. You can keep plants in the greenhouse until the weather improves and move them out towards the end of the month. Just make sure they’re well watered and the greenhouse is well aired, vented and shaded during the day so that these plants don’t over heat in warm weather. The same rules apply for hanging baskets. You can plant these from April onwards, but until the last sign of frost has passed you may want to protect them in the greenhouse. If you don’t have one, hold off planting until the end of May. Line your basket well and add a fertilizer rich compost soil. There are plenty of varieties to choose from but trailing plants work well for covering the sides of your basket. Water well, add fertilizer weekly and keep any eye out for pests!

Tidy up

You may find you need to clip any hedging and topiary now to keep its shape neat and tidy. The warmer weather will also mean regular mowing of the lawn will be a necessity now and through the summer months. Once a week should be sufficient, keep on top this and your garden will look tidy all summer!

Deal with weeds

As the temperatures rise your prized plants will spring to life, but unfortunately so will any unwanted weeds! Pull up any seedlings and dig out perennial weeds with a fork to try and get rid of any roots. Time and effort spent on these perennial weeds will benefit not only your borders but also your lawn, as May is the ideal time to identify those nasty dandelions and deal with them.

Pond

If you have a pond, pond weed is equally important to deal with and should be removed regularly before it becomes too difficult to manage and harmful to pond life. Make sure you leave any weeds by the side of the pond for a good while before removing just in case any pond life is hiding there!May is a great time to begin stocking ponds with fish, just make sure any aquatic plants have established first.

Keep an eye on growth

Many growing plants may need your attention this month, add plenty of feed to keep them happy. Tall perennials may need trellis and support as they start to grow to keep them straight and upright.It is also important to tie up your clematis to control their climbing in the direction you would like them to grow. For rambling roses, try and tie as horizontal as possible as this will restrict the flow of sap and increase side shoots, thus causing more flowers. Spring flowered Montana type clematis need pruning after flowering to keep them tidy.

Gardening Jobs for April

Get set for summer
Now would be a great time to think about your summer garden. There’s still a few months left of spring but it won’t be long until the weather improves, in theory. Add some seating areas and get your summer garden furniture now and you’ll be immediately prepared to take advantage of any sunshine we get.
Summer Bulbs

You can start planting summer-flowering bulbs out from mid-April. The winter
months are over and we can expect far less harsh conditions for your plants. Keep an eye on the weather however as frost is always a possibility. If the weather forecast looks chilly, keep your bulbs inside until it perks up a bit. Shrubs and spring flowering bulbs will appreciate a bit of feeding at this time of year in preparation for the growing season.

Control Pests
The first green shoots of new growth are very susceptible to damage from slugs and snails. Container grown plants can be protected by copper rings around pots. Slug pellet application is always effective however a gravel barrier/border can also be a natural deterrent. Weeds will also become an increasing problem with the weather improvements so keep those under control.
Tidy up
The weather will begin to improve and provide a suitable climate for preparations for summer flowering bulbs and the ideal platform for tidying up your borders/shrubs after the long winter. Deadhead spring bedding plants and remove tired winter bedding. Prune shrubs and hedges now before the birds begin to nest to encourage healthy new growth. All deciduous shrubs need pruning as soon as they have flowered. Often the most leggy and untidy shrubs can be pruned hard now to create a much neater and compact specimen.
Treat the Lawn
April is the most important month when caring for your Lawn. Your lawn will need cutting approximately twice a week by mid-April. Think about sowing new lawns or repairing any bare patches. Applying feed at the start of the month will be beneficial for stronger growth. In a mild period, apply feed evenly and economically. Use a wheeled distributor if possible. Now is also the perfect time to apply weed killer to your lawn.
Get your trellis prepared for climbing plants
Now is the time to put up trellis in preparation for your existing or planned climbing plants. Soon your Clematis or Honeysuckle will burst into life and demand climbing assistance.

How to Plant Roses

climbing-roses-on-trellis-2

Few shrubs/plants will add the elegance and beauty to the British garden quite like a Rose. Roses can come in a number of colours, shapes and sizes and are grown for their attractive and often fragrant flowers, flowering mainly in summer and autumn.

Ht-roses
HT Roses. Prolific flowering, scented well formed blooms, these classic and popular roses are prized for their distinctive colour and shape. From left to right Lovers Meeting, Black Baccara and Sunblest.

Roses are ideal for planting as stand-alone specimens, planted together in groups, miniature roses can be used in raised beds and climbing varieties to climb a wall, trellis or a fence. All make perfect cut flowers.

Rose-Tickled-Pink
Floribunda Roses. Produces in clusters these really give you more roses for your money! Great bedding plants and good in the vase, the blooms are open and less of a classic rose shape than the HT varieties but they do have a real charm that’s all their own. Image variety Tickled Pink.

How to Plant Roses

 

To plant, dig a hole large enough to take the roots when fully outspread, remembering that the point at which the plant was originally budded should be sufficiently low in the hole to be 2.5cm below the surface of the soil when it is filled in. Distribute the roots evenly round the hole and put in a little fine soil to which has been added a small amount of bone meal.

Fill in a further 5cm of ordinary soil over the roots and tread in firmly. Tread in additional soil firmly at each stage as the hole is filled. Roses must be firmly planted. If they are not the winds of winter will loosen the roots and may cause the newly planted rose to die.

Generally speaking, the depth of holes in which the roses are to be planted will vary between 10-20cm but examination of the plants will show quite clearly the depth to which they were originally planted and this depth should be adhered to provided that it does place the point at which the stock was budded just below the surface of the soil.

Still impossible but highly coveted – the elusive blue Rose. These two are the closest you can get in nature, Rose Blue Moon and Rose Rhapsody in Blue.

How to Prune Roses

(Bush Roses, Floribunda or Hybrid Tea)

Bush Roses should be well pruned in mid-March in Southern England and further north this should be deferred at such a rate that in the North of Scotland it is done in the second week of April.

Floribunda Roses are a little tenderer and should be pruned one week later than the above dates.

Newly planted Hybrid Tea Roses should always be pruned back hard in the spring, provided the roots are firmly established, leaving only three or four eyes per stem, generally leaving about 15-25cm in length. Roses are roughly pruned in the nursery to approximately 35-45cm of stem. If left unpruned they will die back along the stem and perish or produce leggy poor specimens.

Climbing Roses

 

Do not prune for two years after planting and then only sparsely, removing unrequired growing tips. Weak or dead wood should be removed.

Standard Roses

Standard-Rose-Pascalli-0001746

Stake well with expandable ties, driving in the stake below the head of the tree. Plant Rose Tree to old soil mark level. Put liberal amounts of planting medium in hole. Prune back well in spring to good bud. You’ll find a helpful How To Video with our garden expert Jeff Turner here.

Miniature Roses

H390_H392_H394_-Three-Rose-Fairy

 

These are miniature versions of Hybrid Tea or Floribunda types and should be treated the same allowing for the difference of scale. Miniature Roses are ideal for borders and rockeries or as pot plants, though they should be in the dry atmosphere of the house only for limited periods. Prune hard after planting.
