Although spring only officially starts on September 1, we don’t need a calendar to see that spring is on the way.

For most of the country there is a delightful springiness in the air. Although August is warm to even hot in parts of the country, apply these rules when planting or sowing plants that are sensitive to frost damage:

In frost-free areas, start planting at the beginning of August.

In areas of light to moderate frost that lasts until about the end of August, plant in early September.

In areas with late frosts or winter rainfall, wait until late September.

Push aside the winter chills and spring into action.

An African appetite

Have you considered growing an edible local fruit? These shrubs, trees and ground covers can form an aesthetic part of your garden and become a valuable, unusual food source:

The kei-apple (Dovyalis caffra) is an evergreen large shrub, or small tree, that creates an impenetrable hedge with its spiny thorns.

The kei-apple (Dovyalis caffra) is an evergreen large shrub, or small tree, that creates an impenetrable hedge with its spiny thorns. The yellowish-orange fruits are delicious and mostly used for jam, jelly and syrup-making. The flowers feed honey-bees and attract butterflies while the fruit is a delicacy for several birds.

The shrub num-num (Carissa macrocarpa) and the ground cover num-num (Carissa macrocarpa ‘Green Carpet’) both have beautiful glossy leaves with compact, thorny growth. They have star-like white flowers which have an orange-blossom fragrance with elongated mini plum-like num-num fruit, which is red when ripe. They can be eaten raw or made into jams or jellies. The num-num shrub is also rather impenetrable as a hedge. Carissa’s love the coastal weather but grow in most areas with light to mild frost.

Tip: They attract birds and butterflies and their flowers feed honey bees.

The cross-berry (Grewia occidentalis) is a fine, hardy landscaping shrub that produces little purple berries, which are relished by birds and man alike. The dried fruits can be boiled in milk to make a bushveld milkshake or a great tasting African beer.

Bush geraniums (Pelargonium x hortorum) and ivy, or cascading geraniums (Pelargonium peltatum), are some of the most sought after of our indigenous plants.

Flowering in pots, ready to add colour to the patio or the garden, are Pelargoniums.

Geraniums are incredibly rewarding as garden plants and do exceptionally well in containers too. They love a sunny to semi-shade position and well-drained soil that should be moist but not wet. Give them a weekly mild liquid feeding for excellent results.

Coloured arum lilies: Although hybridised, they stem from our indigenous arums or Zantedeschias. Often referred to as Zant’s, they have the most beautiful, elegant vase-like flowers in gorgeous colours. You can buy them already in flower, in a pot, or as bulbs.

Tip: Zant’s are best planted in the sun.

Lemon-scented verbena, also known as Aloysia.

Fruity fragrance

Lemon-scented verbena: Also known as Aloysia, this is a must-have if you enjoy drinking deliciously refreshing lemony tea. A delightful drink is easily made from the scented leaves or you could use them to add fragrance to the garden. If you locate the plant close to a path, the lemony scent will be released whenever a person brushes past the leaves. This rather wispy looking shrub can reach up to 2m in ideal conditions, but normally about 1m tall in areas of light to moderate frost as it can survive a little icy chill. Prune back every spring if you prefer a dense, bushy plant. It is easy to grow and the sprays of white flowers it bears are a bonus.

Claim to fame: The lemon-scented verbena leaves contain essential oils, which have many culinary and aromatherapy uses.

Tip: Verbenas like well-drained soil and prefer not to be watered in the evenings.

Lawn

Proud or pitiful? What makes the difference?

It’s time to give your Kikuyu lawn a boost with some spring treatment:

Scarify: Use a steel rake to remove thatch- the dry matted grass at the base of the leaves. The vigorous use of a plastic rake or hard-bristled yard broom can also work.

No 1 haircut: Mow the lawn with the mower blade set low.

Spike: Use a garden fork or aerator to punch holes all over the lawn.

Fertilise: Chose a fertiliser recommended by your local GCA Garden Centre.

Water: The lawn gets thirsty too!

Dress: Spread lawn dressing over the lawn and rake it evenly over the surface. A 30dm3 bag of lawn dressing covers 4 to 5 square metres.

Now just watch and wait for your stunning new grass to appear through the lawn dressing. Fertilise monthly for best results and water at least once a week until the rains start.

Shopping list:

A good, strong rake

Sharp new lawnmower blades

Garden fork or hollow tine aerator

Lawn fertiliser
