Plant sun-loving sunflowers, celosia, brachycome, zinnias, Californian poppies, marigolds, nasturtiums, petunias and phlox for a brilliant summer display.
Impatiens, bromeliads, cinerarias, violets, pansies and coleus will brighten up shady spots.
Apart from good soil preparation and feeding, a regular watering regime is essential for fast growing vegetables to produce good crops. To minimise fungal problems water plants in the morning as evening watering, especially in humid weather, may result in disaster.
If you notice brown lines through the flesh of potatoes when peeling them it is most likely net necrosis which occurs when potatoes have gone through a period of stress while growing.
The vascular system at the stem end of the potato breaks down causing this brown discoloration. Just cut the streaks out.
As gardens have become smaller the popularity of miniature roses has increased.
The result of an accidental cross in the 1930s, miniature roses grow to no more than 50cms high with a diameter of around 30cms. They make ideal edging and potted plants, and in the open garden are seen at their best in groups of three or five at spacings of about half-a-metre apart.
WEED OUT PROBLEMS
Cape weed grows in flat rosettes and often forms a thick yellow carpet when flowering.
Dig out this insidious weed as soon as plants are seen because it spreads very quickly and smothers all in its path.
Laurus nobilis 'Baby Bay' is a new dwarf form growing to about one to two metres high with a compact growth habit, making it perfect for pots or a low hedge.
Clipped as a topiary or standard it looks great as a centerpiece for a vegetable or herb garden, and makes a bold statement planted in a pot as a feature plant.
The aromatic leaves are a popular culinary seasoning.
Blueberries grow as thornless shrubs and ripen in late summer into autumn.
The soil should be deep, well-drained and have a pH of 4.5 to 5.5. Don't use lime near these plants as they are very sensitive to it.
The fruit changes colour as it matures from green to red to blue.
They can be planted as a hedge or in the shrub bed.
Too much nitrogenous fertiliser can cause the fruit of apple trees to turn brown on the inside.
If this is the case use a fertiliser with a NPK of 2:2:1 instead of one containing a high level of nitrogen and only give the tree enough water to keep growing.
