Bulbs are an excellent addition to any garden. They provide a splash of colour in your borders throughout the year, many can also be planted in containers to provide a burst of colour anywhere in your garden, or even in your lawn to give an informal look to your grassed areas.

Buying bulbs

Buy bulbs at Jacksona Nurseries Most bulbs have a long period of dormancy, meaning they require very little attention for most of the year. When choosing bulbs, look out for big, fat, firm bulbs, these will be the healthiest ones. Avoid any which are damaged, shrivelled, soft or mouldy, as these are likely to fail, leaving you with a disappointing gap in your flower beds. When buying bulbs, aim to plant them within 1 week of purchase to prevent them sprouting too early. Keep them in a cool, dark place until you are ready to plant. 

When to plant bulbs

Bulbs can be planted throughout most of the seasons, the best time to plant them depends on the variety and its flowering time. Spring flowering bulbs are generally best planted in early autumn, summer and autumn flowering bulbs are best planted in the spring.

Spring flowering bulbs (to plant in autumn) - Nerines, Daffodil, Snowdrops (variety specific), Crocus, Hyacinth, Lillies, Allium, Tulip, Crocosmia, Iris, Narcissus, Ranunculus, Tree Lily, Anemone, Fritillaria and Muscari

Summer/Autumn flowering bulbs (to plant in spring) - Gladioli, Begonia, Cardiocrinum, Dahlia, Bluebell, Ponerorchis and Snowdrops (variety specific).

Where to plant bulbs

Different species of bulbs will require different types of soil and sun conditions, so it is always best to check any packaging before you plant them. As a general rule, most bulbs require well drained soil, as any waterlogging over winter can cause the bulbs to rot before they have even sent out any shoots. Hardy bulbs, such as Daffodils and Tulips, prefer a warm, sunny site, whereas bulbs from cooler climates, such as Cardiocrinum, prefer a cooler, moist site with dappled shade.
Many bulbs look stunning when planted in bold drifts in borders, such as Fritillaria and Crocosmia, but they can look equally beautiful when planted in containers or even in a lawn. Snowdrops lend themselves well to any of these situations, especially lawns, whilst Tulips and Lilies look spectacular when planted in containers. Drainage is key with bulbs, so no matter where you choose to plant them, ensure there is adequate drainage.

How to plant bulbs

Always plant bulbs with the growing tip facing upwards. With some varieties the growing tip is not always obvious, in which case planting them on their side will ensure the shoot heads for the surface, no matter what end it is. Remember, bulbs can also be combined with other summer bedding plants to create a beautiful display. Violas, Erysimum and Forget-me-nots are great for combining with the striking colours of Tulips.


When planting bulbs in your garden borders, aim to plant them in groups of at least 6 to provide a better display. Dig a hole wide and deep enough for your bulbs. As a rule of thumb, measure the bulbs from the base to the tip and double or triple this measurement to get a rough idea of the planting depth. Our planting depth diagram will also help you to work out how deep to dig your hole. Place the bulbs in the hole with their growing tip facing upwards. Space them at least twice the bulb’s own width apart. Replace the soil and gently firm it, avoid doing this with your feet or too much force as this can damage the bulbs.

Most bulbs are ideal for growing in containers, but showy flowers such as Tulips and Alliums make great statements. Use a good quality multi-purpose compost in your containers combined with a handful of grit to improve drainage. Specalist bulb compost is also available. Plant bulbs as you would in a garden border, but they can often be planted closer together to provide a stronger display. If mice and other pests are a problem, cover the top of your pots and containers with chicken wire or mesh until the new shoots appear. Pots may need protection from frost during the winter, so wrap the pots with newspaper or horticultural fleece. Clustering several pots together will also help them to stay warm.


Bulbs grown in an informal lawn can make a spectacular display. The key is to keep the appearance informal and natural. The best method of achieving this is to scatter your chosen bulbs on top of the lawn. Wherever each bulb lands, dig a hole with a strong trowel and plant according to the required bulb height. Replace the soil and gently firm to remove any air pockets. Avoid treading on this area of lawn as this may result in the bulb becoming damaged. A good time saving method for larger areas is to remove the turf and plant the bulbs underneath en masse. Once the new shoots appear, leave the lawn mowing until they have finished flowering and the leaves have started to die back. 


For a more spectacular display, bulbs should be planted in groups. The size of the group depends on the type of bulb. See the table below for details on some of the recommended densities

  Bulbs per metre squared
Allium schoenoprasum 50
Colchicum autumnale 150
Crocus chrysanthus 'Snow Bunting' 75

Galanthus nivalis 'Flore Pleno' (double) 225
Galanthus nivalis 'Lili Wen Fach' (single) 225
Hyacinthoides non-scripta 150
Narcissus 'Tete a Tete' 75
Tulipa 'Red Riding Hood' 50
Tulipa sylvestris 50


After planting your bulbs, ensure that the ground around them does not get trampled or squashed, as this can cause the bulbs below to break, which in turn will hinder their growth. Keep the planting areas well watered throughout the growing period. Pay extra care and attention to any bulbs in containers and pots as they will require more water than those in flower borders and beds. Although they can look ugly, plant tags are essential for remembering where you planted your bulbs, and will prevent you from accidently digging them up in the spring and summer. To promote a good show of flowers next year, feed your bulbs every 7-10 days with a high-potassium feed, such as Westland Gro-Sure Tomato Plant Food. Begin to feed them once the shoots appear and stop once the foliage has started to die back. 

Tulips and other bulbs re-flower well if they are removed from the soil. After flowering, remove the seed heads and wait for the foliage to die back. Once this has happened, lift the bulbs from the ground, clean off any soil and store them in boxes or net bags in a cool, dry place until next year.
