Bulb Planting Advice


Growing Summer Flowering Bulbs


 


Acidanthera murielae


 

They take a long time to develop and as a rule don't flower until September. Plant 8cm deep with a spread of 15cm.

 


Agapanthus


 

Also known as the African Lily these perennial plants flower from Mid Summer to Early Autumn, they thrive best in a well-drained sunny position. If grown in pots they do their best once they become root bound, they should be protected from frost in the Winter bycovering with straw or bracken. The crowns should be planted 2 inches below the soil surface.

 


Alstromeria Ligtu Hybrids (Peruvian Lily)


 

Plant tubers deep, 25cm, in rich well drained soil in a sheltered place preferably facing South. Apply a thick mulch of compost every Autumn. 

 


Amarcrinum Howardii


 

 A cross between Amaryllis and Crinum. Follow the same cultural instructions as Nerines.

 


Anemone coronaria


 

Plant in rich well drained soil from December until May, incorporating some well-rotted manure. By staggering the planting time a continuous supply of cut flowers may be obtained.

 


Bessera elegans (Coral Drops)


 

Plant 5cm deep in March in a sheltered south facing border.

 


Caladium


 

Plant in April in humus rich soil and water liberally when growth has emerged. Shade from the hot mid-day sun to ensure the best colour effect. Not winter hardy in most places so treat like Dahlias and lift tubers in Autumn.

 


Canna


 

Treat in a similar manner to Dahlias. Plant out in April in well cultivated soil in a sunny warm place. Lift the tubers after the first frost in Autumn and store frost free in the Winter.

 


Convallaria majalis (Lily of the Valley)


 

Plant the crowns in a moist soil in a shady place with the roots spreading well downwards. They normally require a season to become establised, thereafter they will flower more profusely each year.

 


chlidanthus fragrans (Peruvian Daffodil)


 

These may be grown outside in milder parts of the country provided thet are given winter protection, otherwise they should be lifted in the Autumn and replanted in March.

 


Crinum


 

A good plant for a sheltered border, plant the bulbs with the neck showing just above the soil level and cover in Winter with a layer of bracken or compost.

 


Crocosmia


 

An excellent border plant should be planted approximately 10cm deep with room to spread as they increase rapidly once established.

 


Cosmos Atrosanguineus


 

Also known as "The Chocolate Plant" for its colour and scent. Treat in the same manner as Dahlia tubers and plant in April. The tubers are slow to develop, usually flowering between August and October. Frost protection should be provided in the garden.

 


 [Hardy] Cyclamen


 

Plant in a dampish site working in plenty of leaf-mould and apply a top dressing of the same when plants are dormant.

 


Eremurus (Foxtail Lily)


 

Plant tubers with the crown level with the soil but not covered. Good drainage is essential. Mark planting area with a cane to avoid treading on the tentacles and causing damage.

 


Eucharis


 

Member of the Amaryllis family. Good drainage is essential so use a loam based compost, such as John Innes No. 2, mixed with grit or sharp sand, two parts compost to one part grit or sand. Plant tubers with crown level with the soil but not covered.  Mark planting area with a cane to avoid treading on the tentacals and causing damage. When the plant is growing strongly ensure that it has plenty of water and feed once every two weeks with a high potash fertiliser, such as tomato feed. Do not let the bulbs dry out.

 


Eucomis


 

Plant in a sheltered border of large pot, approximately 15cm deep and about 30cm apart. They do require some winter protection. Eucomis need warm, fertile soil with plenty of sun and lots to water during the Summer. Can be difficult to keep upright as they tend to flop and are difficult to stake.

 


Freesia Hybrids


 

Specially treated strain to grow in the garden where they will bloom from the latter part of July to October. Plant in April in a sunny sheltered part of the garden. In dry weather, water regularly. 

 


Galtonia


 

A valuable border plant. Must have fertile, well-drained soil that does not dry out. In really cold areas may need some Winter protection. Provide a good amount of compost in Autumn to provide food and some protection. When in growth they will need plenty of water

 


Gladioli


 

They will thrive in any good garden soil but like it to be well drained. Plant form March until June, 10cm deep and the same distance apart.

 


[Medium Flowering] Gladioli


 

Recommended planting depth of 6-8cm. These varities are naturally sturdy and about half the height of the standard Gladioli sou are ideal in borders or pots.

 


[Dwarf] Gladioli


 

Commence flowering in June and last for a long period throwing up secondary spikes. Like the larger Gladioli they prefer good garden soil and should be protected from severe frosts.

 


Gloriosa


 

Plant from February to April in a greenhouse where temperature can be maintained around 60F/16C. Use a 15-20cm pot and plant in light loam mixed with compost. Plant is of a climbing habit.

 


Hippeastrum Sonatini


 

An Amaryllis suitable for planting in the garden, they may be left to naturalise, we would recommend providing some protection during severe Winter weather by covering the area with tree bark or bracken in the dormant Winter season. Plant from March onwards with the neck of the bulb is still exposed in well-drained soil. Keep the area watered during the growth stage and fertiliser can be added once you have seen the first leaves develop. Hippeastrums are also ideal for pots. 

 


Liatris Spicata


 

Commonly known as "The Gay Feather" this plant will grow in most conditions but performs at its best in moist fertile areas.

 


Nerine


 

The ideal situtation is against a wall facing Souuth, setting the bulbs with the nose just below the soil level. When plants have died down they should be covered with a thick layer of bracken to give Winter protection. Nerines are best left undisturbed. When clumps become congested lift and replant after flowering. If required for pots, cover the bulbs half way up the neck and set in a frost-free place until April. Water freely when in full growth but withold water while dormant.

 


Ornithogalum


 

Bulbs will multiply rapidly to form dense stands and are a favourite in cut flower arrangements due to their lasting qualities.

 


Pleione


 

Surprisingly easy to grow but requires some Winter protection.

 


Polianthes tuberosa


 

These make superb plants for pots and cut flowers. Grow in a warm sheltered place with maximum sunlight. Lift in Autumn and store frost-free.

 


Rhodohypoxis


 

A small genus of tuberous plants. These plants are suitable for either containers or as a rock garden, they are hardy provided they do not get too wet and the temperature does not fall below zero in the Winter. It may be advisable to cover them during their domant season.

 


Sandersonia aurantiaca


 

Plant in mid-March in a sheltered South facing position and use pea sticks to support the plants. In cold areas start in pots in a greenhouse using a mix of John Innes No. 2 and sharp river sand.

 


Schizostylis


 

Known as the Kaffir Lily, plant in a sheltered position in a light well drained soil and protect during Winter especially in gardens in the Northern areas of the United Kingdom.

 


Sprekelia formosissima (Jacobean Lily)


 

It can be over-wintered outdoors in mild districts but it needs a warm sheltered place. Set the bulbs just below ground level and apply a protective layer in the Winter. If in pots, cover the bulb up to two-thirds and keep in a cool greenhouse.

 


Tigridia pavonia [Mixed]


 

Flowers only last one day but every spike produces a succession of flowers and each corm throws up several spikes creating a continuous display through July and August. Plant 7cm deep in a sunny of semi-shaded position.

 


Tulbaghia


 

Native to South Africa it should be treated in a similar way to an Agapanthus. For best results plant in a dry sunny position. An old wives tale says to plant them in pots near your doors and windows to keep away mosquitos.

 


Zantedeschia (Calla Lily)


 

Under normal conditions they are perfectly Winter hardy and will only suffer from the most severe conditions. A well-drained soil incorporating plenty of compost or well-rotted manure suits them best. Plant corms about 10cm deep in either a sunny border or a container.
