Planting Spring Bulbs

PLANT SPRING BULBS NOW

It is always very uplifting to see the emergence of the first spring flowers after a long dark cold winter. They are the sign that winter is ending and warmer weather is on its way.

Traditionally March was the turning point when shoots started to appear, then up popped the first snowdrops and winter aconites. Global warming has changed all that, but climate change is not occurring gradually. It is a bit like the stock market, over time it improves but has wild swings along the journey. Several years ago I was enjoying a coffee break outdoors in glorious warm sunshine at the end of February. Last April my early tulips were broken down with the weight of snow on them. I used to think Narcissus February Gold was a joke as it flowered in April, but now it almost does flower at the end of February. See the drifts of them along the Lochee Road next February or maybe March.

This is the time of year to be planning, buying and planting bulbs for that early flower display. The garden Centres, nurseries and stores are full of bulbs for every situation around the garden.

Bulb planting ideas

Bulbs start to flower in February with the snowdrops and continue till mid summer with the lilies. They will give a more impressive display if they are planted in bold drifts. They can also be mixed together with several types of bulbs to extend the season of display. Snowdrops can be mixed with crocus and tulips which are planted deeper and also summer lilies which flower much later, but all grow happy together.

However consider the location for each type. Snowdrops, aconites, bluebells, chionodoxa and grape hyacinths are all happy in partial or dappled shade, whereas crocus need sunshine to open up the flowers. Many bulbs thrive under deciduous trees as they do their growing early before the trees develop a dense canopy. Often this canopy will dry out the soil surface in summer which may suit the bulb during its dormant stage.

I find numerous places to grow bulbs in association with other plants such as in the herbaceous border, coloured stemmed or winter border, woodland border amongst the Himalayan blue poppies, and of course in the spring bedding displays in borders and tubs.

Bulbs, such as hyacinths and narcissus can also be grown in pots for the house, then later after flowering dried off and planted out in the garden.

Early flowering bulbs such as narcissus and crocus can be planted in lawns, but remember to let the leaves grow to feed the bulbs for the following years flowers. Always allow a minimum of six weeks from flowering before mowing off the leaves, though many people will advise to leave them till they begin to turn yellow. In some wet years that can take a long time especially with the large headed daffodils.

Another great plant association is a drift of Anemone blanda with Cyclamen hederifolium as they both have totally different flowering and growing seasons. Anemone blanda flowers in spring, then grows quickly till mid summer before dying down. The cyclamen flowers emerge in late August to September and continue to grow till winter before dying down.

To capture and enjoy the beauty of those first flowers in late winter plant some snowdrops, aconites and crocus species in view of the main house windows. Then even after a snowfall you can still see them emerging unscathed from the comfort of a warm house. I have a drift of these next to a beautiful pure white Christmas rose, Helleborus niger which flowers at the same time and viewed from the patio window.

Bulbs for the house

Hyacinths are hard to beat for a flowering scented house plant and come in many colours. My favourite was always the red Jan Bos, but there are excellent blues, pinks and whites. For the earliest flowers choose bulbs that have been prepared for forcing and try to get them potted up at the end of August or early September.

Bulbs can be planted close together, even one above the other in bulb fibre compost in wide pots. Water them in then put them outdoors against a north wall. They prefer to be kept dark at this stage for about ten or so weeks and protect them from frost and mice.. This encourages root growth but holds back leaves and flowers. They should not need much watering. Keep checking them for signs of shoot growth and as soon as they begin to grow, probably in late November to December, introduce them to a light but not sunny place such as a cold frame or cool greenhouse. Keep them cold but frost free, until the flowers begin to show. Gradually warm them up but leave it to the last minute before you take them into the warmth of a house otherwise they will grow too tall.

Early narcissus and dwarf tulips e.g. Red Riding Hood, can also be grown in pots for early flowering. I like the scented Cheerfulness types which have double flowers and a heady perfume. Grow them the same way as hyacinths.

Bulbs for the garden

My season starts in early February with a clump of snowdrops planted under my grape vine on a south facing wall which gets a lot of heat from the sun. Then other snowdrops, aconites and crocus species all come together. Crocus should come after the snowdrops, but not any more. Anemone blanda is drifted under our apple trees and follows the crocus before the bluebells smother the ground under our Bramley apple and Victoria plum, all happy to grow together. In the front of our fruit tree mini orchard, (five trees) there are drifts of lilies which grow up into the sun.

The herbaceous border is covered in hyacinths previously grown in pots but now naturalised plus Chionodoxa, the Glory of the Snows. One display after another.

Where ever there is a space amongst shrubs I have planted sacks of daffodils, narcissus, tulips and grape hyacinths which are all left to grow and spread as they wish. I keep adding to them every year. Types of fosteriana tulips have large flowers, are very early and naturalise well.

Tubs and Beds

My Parks Dept training as a gardener was very thorough so I always follow our tradition of planting both summer and winter bedding plants in borders, tubs and hanging baskets.

At this time of year the normal selection will be Wallflowers, Myosotis, Polyanthus and winter flowering pansies.

I choose the tall Darwin Hybrid tulips for interplanting amongst the wallflower, but dwarf early tulips or species to go between the others.

Tubs and pots are also planted with dwarf tulips amongst the pansies and myosotis and often a few crocus are added to give an early display.

I do not use bulbs in my winter hanging baskets as these are usually filled with winter pansies which can suffer from too much foliage from the crocus which just loves to grow when you water and feed them.

All of these bulbs get dried out after flowering to be reused elsewhere in the garden the following year.

The Winter Garden

Plan a garden for colour all year round

A garden can have year round interest with the availability of such a wide range of plants to choose from at local garden centres, or by mail order from a host of excellent gardening magazines.

It is very easy to create interest from spring to autumn, but winter can also have its charm to be enjoyed through the window of a warm home, or to wander round the garden on those cold but pleasant sunny winter days.

The Winter Garden

When the summer flowers fade, the last roses get frosted and the few remaining leaves with autumn colour fall off, now is the moment the winter garden gets some attention. An attractive winter garden full of colour is much appreciated during the long winter months of cold weather and short days.

Plan the garden

It is a useful exercise to make a list of all the different types of plants you wish to grow, pondering through gardening books, visiting garden centres, botanical gardens or National Trust gardens of stately homes or look through gardening magazines to find out what can be grown successfully in your own area.

Consider ground cover including heathers, coloured stemmed shrubs, flowering shrubs, scented shrubs, climbers and for late winter plant some early flowering bulbs.

The winter season

In past years the winter garden began its season in late autumn as other parts of the garden were going into dormancy. The recent climatic changes brought about by global warming effects have given rise to an extended season for many plants. We now get roses and geraniums up to December. The autumn leaf fall now happens in early winter and yellow Jasmine can easily provide a beautiful Christmas table decoration combined with red carnation (purchased.)
Spring flowering bulbs no longer wait for spring but are ready to put on a show from January onwards. These really are a bonus for the winter garden.

A Scottish garden

My winter garden in sunny Dundee has only a few square metres combining ground cover plants, shrubs with coloured stems, climbers at the back, a specimen tree and all underplanted with bulbs.
The show begins when the tree and shrubs lose their leaves to reveal the brilliantly coloured stems of Cornus sibirica Westonbirt and Mid-winter Fire, Kerria japonica, Leycesteria Formosa and the dazzling orange stemmed willow, Salix britzensis emerging from the ground cover of the black grass, Ophiopogon nigricans. This grass is quite black forming dense ground hugging clumps that give a perfect background to a drift of snowdrops. Now white on black; that’s different.

I did have a black stemmed Cornus kesselringii but I am afraid it was a curiosity, not quite a thing of beauty to warm the soul on a cold winter’s day so it has been relegated to the shade border.

The coloured stem border leads into the heather garden where a magnificent specimen birch tree Betula jaquemontia with pure white bark takes a central positio

n within a drift of gold and crimson heather, Calluna vulgaris Beoley Gold and Beoley Crimson. All of these plants are enhanced with the first cold evenings and a bit of frost. The heather garden extends with drifts of a wide range of Calluna and Erica including the winter flowering Erica carnea Springwood white and Springwood Pink.

If there was more room I would include a Rubus cockburnianus, the grey stemmed bramble. This is a lovely grey plant but has vicious thorns.
For those in a more frivolous mood in need of the perfect small specimen tree, I recommend the Japanese maple Acer palmatum Sangokaku and although it is not cheap, it will not disappoint. After the vivid colour of the autumn leaves fall off the bright wine red stems are brilliant in sunshine.

It is important to create a dark background to enhance this border, so consider the fence colour, or use evergreens or climbers on a fence or wall. Climbing plants and wall trained shrubs can be grown on all fences and walls to add beauty, (climbing roses), provide scent, (honeysuckle), give protection, (pyracantha), or provide a fruit crop (figs, vines, or peaches). The winter flowering yellow Jasminum nudiflorum is superb at this time of year.

Spring arrives in February

The winter garden would be incomplete without a heavy planting of spring flowering bulbs drifted in amongst the low ground cover. It is quite feasible to have successional plantings each at their own depth giving a long display of flowers right out of winter and into summer.
The show starts in February when the Aconites, Snowdrops and Hellebore all compete with each other to see who can flower first, followed by the Crocus species. The large Crocus hybrids flower a week or so later, but what a fantastic display they make. Then immediately behind them is the polyanthus a couple of months early, but very welcome.

Cultivations

It is important that the border is kept weed free especially in autumn and top dressed with a mulch of well rotted garden compost. This humus helps to feed the soil, as well as creating a clean darker surface which helps to show off the coloured stems and spring flowers at their best.

In March there is always the occasional warm spring day that brings out the best from the flowering bulbs, and then we know that winter is past. Large drifts of brilliant crocus give way to the first early Narcissi and daffodils. February Gold usually leads this group, though in Scotland more often in March. Above the daffodils the Kerria japonica now puts on its show for a few weeks, before the first of the tulips underplanted amongst the cornus push up and open into the sun.

At the end of March the buds on the shrubs will start to grow, so now is the time to prune them back to a stool to encourage the growth of strong young stems that have the brightest colouring. Assist this growth with a dressing of nitrogenous fertiliser, but only after the flowering bulbs have finished. However I do not prune back the Kerria or Leycesteria. These get a light pruning after flowering by removing some older shoots back to decent fresh young growth.

The winter season ends, but the display continues.

Although the coloured stems have been pruned and the early spring bulbs are finished, I have also planted drifts of tulips which can now add interest to the border in May then these are followed by my scented lilies in mid summer. All these plants seem to work well together without any overcrowding

The show goes on.
