Grow coffee, tea in a pot

Tea and coffee addicts can now turn their drinking habit into a gardening hobby — simply grow your own!

■ Tea

Tea plants Camellia sinensis, the tea camellia, is the common source of tea leaves. But this attractive species of camellia doesn't look anything like the flakes we tip into the teapot.

The leaf tips are harvested regularly throughout the growing season and the different types of tea (green, black and so on) are the result of post-harvest treatment.

Although the tea camellia doesn't have the big, showy flowers found in most garden camellias, it makes a charming garden shrub.

It has glossy, mid-green leaves with slightly serrated edges and pleasantly fragrant, small, creamy white flowers.

While it's fun to harvest your own tea, it's best to allow the plant to establish itself for the first few years before attempting to pick the leaves.

Camellia sinensis does well in the dappled shade beneath larger trees.

It will grow in full sun but must be kept well watered through the heat of summer.

And, in spite of its long association with warm parts of Sri Lanka and India, the tea camellia, a native of China, is surprisingly tolerant to cold.

There are plenty of tea substitutes that can be grown in the garden, too.

The New Zealand native manuka (Leptospermum scoparium) is said to have been first christened "tea tree" by Captain Cook when he infused some of the leaves to make a hot drink.

Lemon myrtle (Backhousia citridora) is an Australian rainforest tree that is grown commercially as a native tea.

Other widely gown plants are infused to make herbal teas.

Growing from seed is a cost effective way of developing a herbal tea garden.

■ Coffee

Coffee (Coffea arabica) loves warmer temperatures much more than the tea camellia. It won't cope with cold conditions and can only be grown outdoors in a frost-free climate.

Fortunately, coffee makes a successful indoor plant.

Coffee's glossy leaves have an attractive pleated appearance and the perfumed white flowers appear in masses along the stems. The flowers are followed by the coffee cherries, a name that doubtless comes from the bright, cherry red colour of the ripe fruit.

Coffee is extracted from the seeds that are found within the cherries, but processing the seeds into coffee is a fairly tedious job that's best left to the really dedicated. So, it may be better to enjoy your coffee tree for its good looks and regard it simply as a talking point.

In the warmer months a normally-indoor coffee tree will appreciate some time outside. Move the pot into a shaded outdoor spot, and then gradually expose it to a little more sunshine. But even though you acclimatise it to the sun, it will probably be happiest in a gentle, morning sun position.

Don't forget that your coffee plant will need much more water outdoors than it did when inside.

Feed with some slow release Acticote or Nutricote pellets in spring and, in cold areas don't leave it outside at the sign of the first frost.
