Childrens Gardening

Crocus

Dutch Crocus and Crocus Species prefer gritty, poor to moderately fertile, well drained soil in full sun plant around 8-10 cm deep allow 75-100 per sq meter

Daffodils & Narcissi

If planted in pots they prefer cool conditions, if they get too warm it could cause the flower buds to die off. Cyclamineus varieties delay cutting until seed has dispersed.

Water later flowering varieties in dry spring weather as they are prone to non flowering if left to dry. Dead-head as soon as the flowers begin to fade, and leave the foliage to die back naturally for at least six weeks. Apply high potash fertilizer during the growing period, this can be stopped once the flowering has finished this will help promote the flower storage for the following year. Lift and divide the clumps if flowering is sparse of congested.

Iris

Grow in moderately fertile well-drained, neutral or slightly acidic or alkaline soil in full sun to light dappled shade. Plant around 10 cm deep and allow around 75-100 per square meter

Miscellaneous Bulbs

Please see our planting guide for full details for each category in this list.

Tulips

Plant in fertile well drained soil in full sun, dwarf tulips like gritty soils, all tulips dislike excessive wet conditions, Once they finish flowering dead head as soon as possible to prevent the seeds from growing, if left it will affect the flower production. Tulipa and Griegii varieties can be left in the ground for a few years. For other varieties once the leaves have died down lift and clean, remove the offsets, and allow them to ripen in a shed or greenhouse, you can replant the larger bulbs the following autumn, smaller offsets can be planted in a nursery bed to mature. Bulb rot may affect tulips planted in poorly drained soil. Aphids can carry virus from variety to variety. Apply high potash fertilizer during the growing period, this can be stopped once flowering has started, this will help promote the flower storage for the following year.

If planting Narcissi in grass or light soil plant slightly deeper. They prefer full sun to partial shade. Allow around 10-15 cm deep allow around 50-60 bulbs per sq meter for the dwarf varieties around 75-100 per sq meter they will tolerate most soils put prefer moderately fertile, to slightly alkaline soil that is well drained and moist during the growing season.

If planted in pots they prefer cool conditions, if they get too warm it could cause the flower buds to die off. Pseudo and Cyclamineus varieties delay cutting until seed has dispersed.

Water later flowering varieties in dry spring weather as they are prone to non flowering if left to dry.

Dead head as soon as the flowers begin to fade, and leave the foliage to die back naturally for at least six weeks. Apply high potash fertilizer during the growing period, this can be stopped once the flowering has finished this will help promote the flower storage for the following year. Lift and divide the clumps if flowering is sparse of congested.

Indoor Flowering Bulbs

Amaryllis Hippeastrum

Plant in loam based potting compost JI No.2. Plant the bulb with the neck and shoulders just above the surface. Place in dappled light or full sun, water sparingly until in growth, you can provide base heat to quicken the process. Feed around every two weeks with a good balanced fertilizer. After flowering remove the flower stem and reduce the water as the leaves begin to die back. When dormant leave in the pot (they hate root disturbance) place in a shed garage or greenhouse to rest, repeat this process when ready to grow again. They can be re potted around every three to five years.

Narcissi

For indoors planting plant in a good compost JI2 with the tops out of the soil, place in a dark place for a couple of weeks to allow the roots to develop, once established bring into the light in a cool room, if the temperature is to high they will bolt and become very long, they can be grown in pebbles, add water to just below the top of the pebbles. Place the Narcissi so they are almost touching and a few more pebbles to slightly cover around half way up the bulb. It is important the base of the Narcissi do not come into contact with the water to prevent mold and rot.

Place the Narcissi in a cool dark place to help establish the root growth, maintain the water level to just below the top pebbles. After a couple of weeks check the root system, if the bulbs feel rooted they can be placed in a light spot but not direct sunlight.

If they are kept in cool conditions they will last longer, this will also help prevent them from getting long and flopping.

Prepared Hyacinths

Plant with the tips of the bulbs just showing through the compost, use a loam-based potting compost JI No.2, you can use bulb fibre (please do not use peat based compost). The pots will need drainage holes; they need to be kept in a cool dark place with a temperature of no more than 45F for around 8-12 weeks to will allow the roots to develop.

When the shoots are around 2.5 to 5 cm high gradually increase the light and temperature, if they are brought out into the light and warmth too soon they can produce elongated leaves and weak flowers. It is important not to get any water on the shoots as this can cause the flower to rot. Avoid water logging the compost, damp conditions together with poor drainage can cause rot and fungal diseases. When flowering is finished they can be planted out in the garden.

Iris

Grow in moderately fertile well-drained, neutral or slightly acidic or alkaline soil in full sun to light dappled shade. Plant around 10 cm deep and allow around 75-100 per square meter.

Lilium / Lily

If you are able to do so, Lilium should be planted on receipt. Should this not be possible, keep them in cool, well ventilated conditions.

Most lilies require full sun for most of the day but will take dappled shade for part of the day (see list below for shade loving varieties). A well-drained sandy rich soil with a little added humus is ideal but a heavy soil can be lightened with course sand or light grit to improve it for your lilies.  Adding a little bone meal to the soil also improved your lily growth.

Different types of lily prefer different soil types as follows:

  • Longiflorum – Lime tolerant
  • Oriental – Ericaceous
  • Species – Most soil conditions
  • Trumpet – Lime tolerant

Plant your lilies around 17-20 cm deep and around 30 – 40 cm apart or, for Trumpet and Oriental Varieties, plant around 20-25 cm for extra protection in the wind when they grow. Lilies grown in containers should be planted around 15 cm deep allow around 10-15 cm of soil above the bulb. Use JI No.2.

You can plant the Lilium slightly tilted to avoid water getting inside.

Pack the soil well around the bulb and water freely to help the soil to settle and prevent air pockets. Lilium will not usually require daily watering: over watering will rot the bulb so keep it moist but not wet.

To feed your bulbs, use a well balanced fertiliser especially high in potash during flowering and as the growth dies back to help keep the bulb healthy. It is important to stop feeding after this time.

After blooming has finished, leave the foliage to die back and nourish your bulbs. The lilies will rest over winter before starting to grow again the following spring.

Problems to look out for with Lilium

Botrytis - This is a fungal disease that affects the leaves it is usually caused by excessive moisture and warm temperatures. The first sign of it is usually brown spots on the leaves. If left untreated the whole plant can decay. Once identified, you should remove the leaves. It is also advisable to spray the leaves when dry with either a copper spray or 1tbsp of baking soda per gallon of water. The disease is not carried by the bulb so it will not affect the growing the following years.

Blue mould – Lilium have high sugar content and bruising or indeed any injury can cause a penicillin mould to form on the injured part. It may look undesirable but this is harmless to the bulb and can be carefully removed. You can dust the bulb with a fungicide and plant as usual.

Viruses – These are usually transmitted by aphids so try to control infections with a garlic spray or insecticide.

The following is a list details possible viral infection;

  • Mottling and flecking of the leaves;
  • Reduction of plant size and height;
  • Distorted growth; or
  • Colour breaking in flowers.

If Lilium show severe infection they should be destroyed to control this as soon as possible.

The Lily Beetle is becoming more of a problem. These bright red insects are easy to spot as they’re bright red. To rid your lilies of these pests either remove them and crush them by hand or use a systemic insecticide on the plant and soil. Avoid moving infected soil to other sites as the Lily Beetle larvae may then spread.
