My Kiepersol died!

My Kiepersol (Cabbage tree - Cussonia paniculata) is dead. Yea, dead.

The first signs were leaves drying out and then all the leaves dropping to the ground every day - and large gouges in the trunk of the tree. Like some animal has been eating the bark. But there are no large animals in my garden. So that was not the problem.

Then, a couple of weeks later, I discovered that I had a Ground Squirrel living in my garden.

(I did not manage to get a photo of him, this one is from Google)

Ground squirrels are primarily herbivorous, and their diet changes with the season. After emerging from hibernation, they feed almost exclusively on green grasses and herbaceous plants. When annual plants begin to dry and produce seed, squirrels switch to seeds, grains, nuts and roots, and begin to store food. They are a bit bigger than a large rat with a fluffy tail and are regarded as troublesome rodent pests for many home gardeners.
Although ground squirrels look similar to tree squirrels and can climb trees, when frightened they generally will retreat to their burrow, and I did find his burrow under all the ferns surrounding my Kiepersol.

So I concluded that he was the culprit causing the early demise of my lovely Cabbage Tree...

Growing the Highveld Cabbage Tree (Kiepersol) from seed

We're deep into Autumn here in South Africa and my Kiepersol is already starting to lose its leaves. Time to stop watering so much, but we've had quite a bit of rain over the last week, so hope it dries out before the real cold weather hits.

(This article is especially for George, who enquired about growing these lovely trees from seeds.)

This evergreen tree makes a beautiful focal point in a garden as it has an unusual shape, interesting gnarled bark and stunning, large, gray-green leaves. It is a short, thick-set tree, rarely exceeding 5 meters in height, therefore making a perfect garden specimen. Even though it is an evergreen, we live in a heavy frost area and my tree loses its leaves in winter, but has always bounced right back every spring. The plant is native to southern Africa : Botswana, Lesotho, South Africa (Cape Provinces, Northern Provinces, KwaZulu-Natal) and Swaziland, where it grows till 2.000m of altitude in the savannah and the mountain slopes, usually in the rocks fissures.

Cultivation
The Highveld cabbage tree (Cussonia paniculata) is cultivated from seed, preferably fresh. One can grow Cussonia paniculata from a cutting, but this is not advisable because it does not make the proper, fleshy, underground rootstock that it forms when grown from seed.

The seeds should be planted in a well-drained mix of river sand and compost (70:30). Germination is erratic - the best results have been obtained with seeds that have been "passed" through birds (Look for the seeds underneath the tree....). First germination occurs after about 2 weeks.

The C. paniculata is an ideal pot plant (plant it in a big pot in a well drained mix), or can be planted as a single specimen or in a cluster - the effect is always striking. Growth rate is about 70cm per year, depending on the climate. The tree is drought hardy and is able to withstand heavy frost after 2 years.

Sow seed as soon as possible as it loses much of its viability within 3 months. However, seed sown in summer months will germinate faster (in about 4 weeks) than seed sown in winter (7 weeks to germination).

Put a mix of rich soil and compost into your seedling trays and place the seeds into them. Cover the seeds to a depth of 5mm with the soil and mulch. Keep moist during germination.

When the seedlings get to a “2-leaf” stage (about 4 months), plant them out into larger black nursery bags.

Make sure seed trays are at least 15 cm in depth to allow the small tubers to form. Do not allow seed to become waterlogged or dry out. Keep seed and seedlings in a semi-shaded area or, if you are planting the seeds now, during winter, keep them indoors in a sunny place, but not sun shining through glass as this can burn the plants.

Transplanting is easy when small. Bigger trees require care with the hug root system that tends to rot upon transplanting if an injury occurs in digging it out.

When ready to plant the sapling into the ground, position a 50 mm size x 1m length of plastic piping vertically near to the sapling, leaving +- 5 cm above ground level.  When watering around the sapling, also pour water into this pipe, as it will encourage the roots to grow downwards looking for the moisture below.  Keep the ground around the sapling well mulched with dry leaves etc to assist with water retention above ground.

Well drained soil, some water and lots of sun.

Maybe you could also try your hand at making a Bonsai with one of the seeds - they do well in Bonsai-form. Due to the stem, which can easily assume contorted forms, and the succulent roots, it is an appreciated subject for the collectors of bonsai.

Kiepersol tree

Trees are beautiful in their peace, they are wise in their silence. They will stand after we are dust. They teach us, and we tend them.

My Kiepersol (Cussonia paniculata subsp. sinuata) in April 2012, just starting to show signs of winter 

Even though most websites say the Kiepersol (Cabbage Tree) is an evergreen tree, that has not been the case with mine here in Tarlton (Gauteng, South Africa). Above is my Kiepersol in April, just before the winter, and below is my Kiepersol last week (Sept 2012) - it was completely bare, looking almost dead, but now sprouting new leaves and heads. 

Over the years it has changed from a single head to four or five, each consecutive winter frost taking its toll. Below you can see a new head forming on an old branch. 

New head and leaves 

Here it is also forming two new heads on an existing branch - so this one will have three heads. 

I planted my 50cm little Kiepersol in 2006 and within a year it had doubled in size. Two years later, in 2009, it had doubled in size again, growing to an impressive 3m within three years. 

My Kiepersol in December 2007 

My Kiepersol in 2009 

My Kiepersol in Feb. 2010 

At the beginning of 2010 it still had only one head and was almost 4m tall, beautifully thick and lush. 

My Kiepersol in summer - November 2011 

During the winter of 2011 it was severely frosted down and in spring sported three new heads, to my utter dismay! My beautiful Kiepersol now seemed destined to take on a completely new look! 

My Kiepersol at the end of Sept. 2012 - almost thought I'd lost it but now sporting brand new spring leaves. 

To date I've had a lovely trouble-free relationship with my Kiepersol. The only problem I've ever had was two years ago when ALL the leaves were sticky - extremely sticky! I gave the whole tree a thorough once-over, thinking it might be a kind of fly laying its eggs on the leaves, but apart from the stickiness there was absolutely no sign whatsover of any insects, no discoloration, no holes, nothing that I could see. And a Google search has also not revealed anything useful. 

Mountain Cabbage tree - Cussonia paniculata subsp. paniculata 

There are two subspecies of Cussonia paniculata. The smaller Mountain Cabbage tree C. paniculata subsp. paniculata has leaflets without lobes and has a limited distribution in Eastern Cape (see pic above) and rarely exceeds a height of 3m. C. paniculata subsp. sinuata forms a larger tree with deeply lobed leaves and is more widespread. This is the form more commonly found in cultivation and the one I have in my garden. They can grow up to 15-20 ft. (4.7-6 m). 

Cussonias belong to a large family Araliaceae, which include Ginseng, Ivy, and several indoor plants. It is also closely related to the parsley family (Apiacae) which includes several popular vegetables and herbs such as carrots, fennel and parsley.

The Highveld Cabbage Tree (Cussonia paniculata subspc. sinuata) is an evergreen tree that grows up to 4m tall. The Common Cabbage tree has long grey stems with smooth bark. Flowers from April to May and fruits from June to September.

This evergreen tree makes a beautiful focal point in a garden as it has an unusual shape, interesting gnarled bark and stunning, large, grey-green leaves. Plants show up especially well in a layout where rocks are used. Gardeners growing indigenous South African plants favour them greatly for their unique appearance. The wood is soft and light and was used for the brake-blocks of wagons. The leaves provide good fodder for stock and the Zulu name refers to this tree as goats' food. The roots are succulent and edible, mashed roots have also been used in the treatment of Malaria.

Afrikaans Name:
Berg Kiepersol

Zulu Name :
Umsengembuzi

Cussonia paniculata_sinuata occurs inland at altitudes up to 2 100 m. It is often found in rocky places from the mountains of the Karoo and Eastern Cape through KwaZulu-Natal and Free State into Gauteng and further north. It grows in crevices filled with natural organic humus and compost. It is commonly found near Johannesburg and Pretoria. It is frost-tolerant and drought resistant.

Uses: Leaves are browsed by Kudu and domestic stock. Baboons eat the young shoots. Ripe fruit is eaten by Bulbuls, Louries, Starlings, Barbets and Mousebirds.

Medicinal Uses: Decoctions are used to treat madness, convulsions, amenorrhoea, heart pains, venereal disease and pains of the uterus.

Growing Cussonia paniculata
The best method of propagation is by means of seed harvested from fresh ripe fruits. Sow seed as soon as possible as it loses much of its viability within 3 months. However, seed sown in summer months will germinate faster (in about 4 weeks) than seed sown in winter (7 weeks to germination). Make sure seed trays are at least 15 cm in depth to allow the small tubers to form. Do not allow seed to become waterlogged or dry out. Keep seed and seedlings in a semi-shaded area. Seedlings can be transplanted at about 4 months, but be very careful not to damage the fleshy roots when transplanting.

One can grow Cussonia paniculata from a cutting, but this is not advisable because it does not make the proper, fleshy, underground rootstock that it forms when grown from seed.

Cussonia spicata (Natal cabbage tree, 5m) is a shapely tree with the same interesting foliage as the Highveld version. In summer, green flowers are borne that look like 20cm long candles.
