Care Instructions for Cryptomeria japonica Funny

The Dwarf, Whimsical Japanese Cedar


Cryptomeria japonica 'Funny' is a delightful and compact cultivar of the Japanese cedar, known for its quirky, dense, and finely-textured foliage. Its soft, fern-like needles and upright, conical shape make it an excellent choice for smaller gardens, containers, or even as an interesting accent plant in mixed borders. At Lakeside Tree Nursery, we are thrilled to offer this charming variety, and we?e here to provide you with expert care tips to help your ?unny?thrive in the British climate.


1. Planting Location

Cryptomeria 'Funny' is well-suited to a range of positions in the garden, though it will perform best in well-drained soil and a sunny to partially shaded spot. It is a versatile plant that will brighten up both sunny borders and more sheltered corners.


Soil: Prefers slightly acidic to neutral soil with good drainage. Avoid heavy, waterlogged soils, as these can cause the roots to rot. Loamy or sandy soils are ideal for healthy root growth.

Space: ?unny?is a small, slow-growing variety, typically reaching a height of 1?.5 metres and a spread of 1 metre at maturity. It is perfect for planting in smaller gardens, pots, or as part of a rockery. Plant it around 1 metre apart from other plants to allow it to maintain its compact, conical form.

2. Watering

While Cryptomeria 'Funny' is relatively drought-tolerant once established, it will thrive with consistent moisture, particularly during dry spells.


Young Plants: Water regularly in the first year to establish a strong root system. Keep the soil moist, but avoid waterlogging, as Cryptomeria dislikes having its roots sitting in standing water.

Mature Plants: Once established, ?unny?will be more drought-tolerant. Water deeply during dry periods, typically once every 1-2 weeks. However, ensure the soil does not dry out completely, especially during prolonged dry spells in summer.

3. Feeding

Cryptomeria 'Funny' is not a particularly heavy feeder, but a light feed each spring will help it grow strong and maintain its healthy green foliage.


Spring Feeding: Apply a balanced, slow-release fertiliser in early spring, just as the growing season begins. Organic options, such as well-rotted compost or an all-purpose fertiliser, work well.

Avoid Over-Fertilising: Too much fertiliser can result in excessive, soft growth that is more prone to damage from frost. Stick to a light feed to maintain the plant? natural, compact shape.

4. Pruning & Maintenance

One of the benefits of Cryptomeria 'Funny' is its naturally compact and sculptural form, which requires very little pruning. However, some light maintenance can help it stay healthy and looking its best.


Light Pruning: Prune in late winter or early spring to remove any dead, damaged, or diseased branches. This ensures better airflow and helps keep the plant healthy.

Shaping: You can lightly trim the tree to maintain its form, but avoid cutting back into older wood, as new growth may not regenerate from these areas. Stick to trimming soft, new growth for best results.

Deadheading: Although ?unny?does not flower, you can remove any dead or yellowing needles to keep the plant looking fresh and tidy.

5. Winter Care

Cryptomeria japonica 'Funny' is fully hardy in the UK and will typically cope with cold winters, but some winter care is recommended, particularly for young plants or those in exposed positions.


Frost Protection: Younger plants or newly planted specimens may need a bit of extra protection during the coldest months. Apply a layer of mulch around the base to insulate the roots, and consider covering the tree with horticultural fleece in very cold weather.

Winter Colour: During winter, 'Funny' can take on a bronze or coppery hue, adding beautiful colour and interest to the garden. This seasonal colour change enhances its appeal even in the colder months.

6. Pests & Diseases

Cryptomeria 'Funny' is generally pest-resistant and less prone to diseases compared to other conifers, but there are a few things to watch out for.


Root Rot: Ensure the plant is in well-drained soil to prevent root rot, which can occur if the soil is too heavy or waterlogged. If the plant? roots are consistently wet, this can cause damage or kill the tree.

Scale Insects: Scale insects can occasionally appear, but they are usually easy to manage. If you spot them, use a soft brush to remove them, or treat with an insecticidal soap or oil.

Needle Discolouration: Yellowing or browning of the needles can be a sign of environmental stress, often from inconsistent watering or poor drainage. Ensure the tree is receiving proper care, with even moisture levels and well-drained soil.

7. Mulching

Mulching around your Cryptomeria 'Funny' helps retain moisture in the soil, insulates the roots during the winter months, and suppresses weeds.


Apply Mulch: Spread a 5?cm (2? inches) layer of organic mulch, such as bark chips, pine needles, or leaf mould, around the base of the tree. Be sure not to pile the mulch directly against the trunk to prevent moisture build-up that could cause rot.

Replenish Mulch Annually: Mulch naturally breaks down over time, so it? a good idea to replenish it each spring to maintain its insulating and moisture-retaining benefits.

8. Propagation

Cryptomeria 'Funny' can be propagated from semi-ripe cuttings taken in late summer or early autumn. These cuttings can be rooted in a well-draining compost mix. However, for the most reliable results and to ensure the tree maintains its specific characteristics, it? best to purchase a young plant from a reputable nursery.


With minimal care and attention, your Cryptomeria japonica 'Funny' will reward you with years of charming, feathery foliage and its distinctive, compact form. Whether used as a focal point, in containers, or as part of a mixed border, this delightful cultivar offers a whimsical touch to any garden.
