Top Quality, Top Size Bulbs Flower Bulb Specialists Since 1868

GENERAL PLANTING AND CULTURAL INSTRUCTIONS When to plant If bulbs are planted in grass, mowing may only take place after the bulb foliage has died off sufficiently, (Narcissi, Crocus and Chionodoxa are suitable naturalising bulbs). It is best to plant as soon as you receive the delivery of your bulbs. If that is not possible open the bags to admit air and place them in a cool, well ventilated room with a temperature of about 60oF. How to plant Bulbs will flourish in almost any type of soil, provided it is welldrained and reasonably cultivated. Very heavy, as well as light sandy soil can be improved by forking in compost or peat substitute.

Depth to plant Failures with bulbs are most frequently due to their having been planted too deeply or too shallow. Unless otherwise stated, a good general rule to follow, is to cover the bulb with soil one and a half to twice its own depth, measuring the bulb from the base to the shoulder. Thus a Daffodil bulb measuring 5 cm (2”) from the base to the shoulder should be covered with 8-10 cm (3-4”) of soil.

CROCUS A family which may flower continuously from September, when the autumnflowering species start to bloom, until the large-flowered Dutch Crocus finishes in March. The autumn-flowering species should be planted in August and September, and the spring-flowering varieties from September to November - the earlier the planting the better the result. Corms should be planted about 8cm (3”) deep in any good fertile garden soil. The winter and spring-flowering species are well suited to the rock garden or the front of borders, and the later Dutch varieties for groups, edging borders or naturalising. For the best results, plant 8-10cm (3-4”) deep, 5cm (2”) apart, and leave undisturbed. Croci are suitable for a pot or bowl culture, with the exception of large-flowered Yellow Crocus, and may also be grown in pebbles and water. It is important to remember that they must not be forced too hard, as too much heat or dryness in the atmosphere will lead to excess of leaf and no flower.

FT: January-March and September-October. FH: 10-20cm (4-8”), depending on variety.

CURCUMA Grow in well-drained soil; add peat substitute or coarse sand to improve drainage. Will also thrive in pots. Plant 30cm (12”) apart just below the surface.

Protect from frost in winter - mulch well around the plant.

FT: June-September. FH: 30-75cm (12-30”), depending on variety.

CYCLAMEN These are supplied in 9cm pots. They prefer to be planted in a shaded area, in well-drained, rich, but not heavy, soil. Cyclamen need to be left undisturbed once planted, and do not always flower in their first season.

FT: January-October, depending on variety. FH: 8-15cm (3-6”).

5

CYCLAMEN TUBERS Plant Tubers slightly on their sides so that any water can drain away freely, planting just below the surface 15cm (6”) apart. Ideal for planting under trees and shrubs.

FT: January-October, depending on variety. FH: 8-15cm (3-6”).

DAFFODILS AND NARCISSI Can be grown in many ways. Some are suited to informal planting in rough grass in sun or partial shade, where they may be left to flower for years without any attention. Some do well in hedged banks; other more formal varieties are suited to borders, where they provide early colour before the summer-flowering plants commence. These can also be left undisturbed for several years. Many of the smaller species and varieties suit rock gardens and will fill small gaps between other plants. In all cases let the leaves die down completely, or at least become yellow, before removing them. This is necessary to allow the foliage to feed the bulbs, thus ensuring flower production in subsequent years. The bulbs do best in soil which is reasonably well-drained, but not too light and sandy, so that it does not dry out excessively - soil conditions are a most important factor in getting the best results.

After flowering, the soil must not be allowed to become waterlogged before the foliage dies, as this can retard bulb growth for the following season. Failures with bulbs are frequently due to planting too deeply or too shallowly. A good general rule to follow is to cover the bulb with soil one and half to twice its own depth. Plant 10-20cm (4-8”) apart, depending on variety.

FT: March-April. FH: 15-50cm (6-20”).

DICENTRA SPECTABILIS Producing up to 80 multiple flowers in their first year and thereafter. Plant in a shady border in well-drained soil 5cm (2“) below the soil and 50cm (19.5”) apart.

DAHLIA Best started off in greenhouse or indoors, but care must be taken against frost when transferring outdoors. Plant with the crown slightly above the soil. Do not divide the roots prior to planting. After planting, water well and keep the soil moist but not wet. Increase watering as the plant grows, taking care not to get the foliage wet when watering. Once replanted in the garden protect against slugs. When flowering has finished, lift the tubers, and store upside down for approx 14 days so that any 6

residual water can drain from the hollow stem. They should then be stored in peat substitute or vermiculite, or between layers of straw or wood shavings, in a frost-free area. If started outdoors, plant the tuber 10cm (4”) deep with the neck under the soil but pointing upwards. Plant tall varieties 90cm (36”) apart, medium height varieties 60cm (24”) apart, small varieties 30cm (12”) apart.

Stylosa This is a rhizomatous type, increasing to form a mat of knobbly rhizomes which are nearly hidden by the tough evergreen leaves. At any time from November 11

through to March the buds can push up, in a long succession when the plants are doing well. If the weather is mild these can be left on the plant in the open; in frosty weather, however, it is much better to pick them for a vase indoors since they are not all frost resistant and will ruin overnight. In a warm room buds open in a very short space of time and emit a subtle fragrance suggestive of Primrose.

FT: November-March. FH: 35cm (14”).

LEUCOJUM A family of attractive plants resembling the Snowdrop but much larger.

They do best in moist conditions. Plant 7.5cm (3”) deep, 10-20cm (4-8”) apart.

FT: March-May. FH: 15-45cm (6-18”).

LIATRIS Fully hardy. Grow in light, moderately fertile, moist but well-drained soil in full sun. Plant 5cm (2”) deep, 45cm (18”) apart.

FT: July-September. FH: 70cm (27”).

LILIUM The cultural requirements of Lilies are so diverse that only general guidance can be given. The conditions essential for growing Lilies successfully may be generally summarised: a cool rooting medium in open porous soil, perfect drainage and, for most Lilies, shade from hot sun near their roots. These conditions can be readily fulfilled when the bulbs are planted in herbaceous borders or among Azaleas and Rhododendrons. In such positions, the young spring growth is protected from cold winds and the ground is kept cool by the shade of the surrounding plants. This is especially needful in the case of those Lilies which make stem roots, as these are only developed freely in shade. The majority of Lilies should be planted 15-23cm (6-9”) apart, 15cm (6”) deep. Surrounding the bulb with sand helps drainage and discourages slugs.

Lilies are remarkably resilient to drought but should never be allowed to dry out. Nor do they want to be sitting in a container without drainage, where a period of rain is going to drown them. Most Lilies grow well in pots. Make sure they are deep enough to allow at least 10cm (4”) of soil above the bulb and use a humus-rich compost. Give liquid feed in the summer. Remove faded flowers as necessary, but don’t cut back the whole stalk until the autumn. Top dress with new soil each spring and re-pot every two years.

The scarlet lily beetle is a growing menace. Spray as soon as you spot any conspicuous adult beetles or their larvae, which are hump-backed reddish-yellow and covered in black slime; these appear from May onwards.

FT: June-August. FH: 45-150cm (18-60”), depending on variety.

LYCORIS Grow in well drained soil in full sun. Plant 9” apart with top 1/4” of the bulb neck exposed. In wet areas best grown in containers. When in growth water freely and feed monthly. Keep dry in summer when dormant. In winter protect with a dry mulch.

FT: August-September. FH: 30-60cm (12-24”), depending on variety.

MIRABILIS Plant in moist but well drained soil in a sunny position. Plant vertically so that top of tuber is about 2.5cm (1”) below ground level 30cm (12”) apart. Lift in winter 13

and store in a dry frost-free building.

FT: June. FH: 60cm (24”).

MUSCARI Very easy to grow, this is a useful and popular clump-forming plant, producing splashes of colour in the rockery or at the edges of beds and borders.

Usually blue (but not always), they are frequently planted between taller bulbs such as tulips and daffodils. They can also be used for naturalising in woodland or planted in swathes. Plant 7cm (3”) deep, 10cm (4”) apart.

FT: April-May, depending on variety. FH: 10-20cm (4-8”).

NARCISSUS PAPERWHITES Do very well if planted in pots filled with a good quality potting compost. Keep them moist and warm and you will get excellent results.

Can also be planted in pebbles with water up to the base of the bulb. Paperwhites look their most attractive when planted in tight bunches, and perform so much better when crowded together. You will get 4/5 blooms to a stem and 2/3 stems from each bulb: for example, planting 7 bulbs in a bowl could produce as many as 60+ blooms. Place directly in window and they will flower in 6 to 8 weeks.

FH: 40cm (16”).

NERINE Once planted they do not like to be disturbed. Plant in a sunny location 8cm (3”) deep, 10cm (4”) apart. Nerine Bowdenii are recommended for outdoor planting in a sunny spot, with the neck of the bulb just above soil surface. Other Nerines can be grown in cool greenhouses or as a conservatory plant.

FT: September-October. FH: 30-60cm (12-24”).

ORNITHOGALUM They should be planted about 8cm (3”) deep and 10cm (4”) apart. Umbellatum and Nutans are very suitable for naturalising in light woodlands or under trees. Arabicum requires lifting and storing in a cool dry place.

FT: April- September. FH: 15-80cm (6-32”), depending on variety.

OXALIS Ideal for borders and rockeries, they are also excellent as pot plants. Plant in a sunny situation about 5cm (2”) deep and 13cm (5”) apart in ordinary well-drained soil.

FT: April-November, depending on variety. FH: 10-20cm (4-8”).

PAEONIA Needs to become established before flowering really well, as flower buds are formed in spring. Select a situation facing north-west, south-west or west, so that early morning sun does not fall on the buds. Before planting, trench the ground as deeply as possible, working in a good dressing of rotted manure. Care should be taken, however, that this does not come in contact with the roots. Do not plant too deeply, the topmost eye should be 1.5cm (1/2”) below ground level. During the growing season an occasional application of weak liquid manure is beneficial. It may not flower in the first year, and will not be fully established for three years.

FT: May-July. FH: 45-100cm (18-39”), depending on variety.

PANCRATIUM Plant in deep containers 15-20cm (6-8”) deep in John Innes No.2 with added grit, when in growth water freely and apply liquid feed monthly. Outdoors, grow in well drained soil in full sun. Half hardy to frost tender.

FT: July-August. FH: 25cm (10”).

PICTORIAL MEADOWS MIXTURE Prepare the soil in late Autumn/early Spring to remove any grass or weeds. Prepare the plot to a depth of 20cm (8”), or 10cm (4”) in previously planted plots. Ensure the area is prepared to a fine tilth, wait a few weeks, then clear any weeds that may have grown, either with a systemic weed killer or by hand. It is most important that the site is completely free of weeds.

Sowing the seed A quick and simple method is to mix the seeds with sand and scatter evenly over the area. The sand will help you see where you have sown. The seed needs light to germinate, so rake in trying not to bury the seed. The suggested sowing is 2-3g per square metre.

The perfectionist’s way Divide the area to be sown into metre squares, measure out the seed required for one square metre, and pour this into a see-through plastic cup.

Mark the depth on the side of the cup - this saves having to weigh the seed each time.

Pour one measure of seed onto a shovel and spread evenly over one of the metre squares using a stick to tap the seeds off the end of the shovel. Gently rake the seed into the soil but don’t bury the seeds, as they need light to germinate.

Maintenance At the end of the flowering season, the dead stalks should be cut off and removed, and the area sprayed to kill off any grass or weeds that have grown during the flowering season.

PLEIONE Will always grow well in the house or greenhouse but must be protected from frost. Plant with tip of bulb just above the surface. They like moist compost during 15

TULIPA Tulip bulbs should be planted in late autumn when temperatures have cooled down, any time up to the end of November; they do not start rooting as early as other bulbs, and should be kept cool when first planted. Bulbs are best lifted to

18

guarantee flowering the following year, bulbs that are left in the ground may only produce a 30-40 percent return the following year. Plant in well-drained, fertile soil in a sunny spot. For Tulips that are to be left in the ground after flowering, pull off old leaves and stems once they have withered and be sure not to leave any tulip petals rotting on the ground. Keep site relatively clear of other vegetation during the summer so that the bulbs receive the sun’s warmth to ripen them. Apply an annual dressing of either potash-rich fertiliser or sulphate of potash in late winter or early spring, before young shoots appear. After flowering the tulips can be dug up if the site or containers are otherwise needed, and the bulbs - complete with foliage - can be planted in an odd corner of the garden out of the way until the leaves turn yellow. Once the leaves have turned completely yellow, lift again and place in boxes in a dry shed or garage where they will be warm but not in direct sunlight. When dry, clean off the old stems, roots and soil and keep the bulbs for replanting in the autumn. Plant 10-20cm (4-8”) deep, 10-20cm (4-8”) apart depending on variety.

FT: March-May, depending on variety. FH: 10-70cm (4-28”), depending on variety.
