Spring garden preparation

As the weather warms up, it’s time to give your garden some tender loving care. Start by clearing away any debris, leaves, or winter remnants from your garden beds. Loosen the soil to improve drainage and aeration.

To prepare your garden for a productive spring, enrich your soil with Wonder Plant Starter All Purpose granular fertiliser. This exceptional blend provides essential nutrients like nitrogen, phosphorus, and potassium, which are crucial for healthy plant growth. The sustained release formula ensures a steady supply of nutrients, promoting strong root development and vigorous growth.

With your garden beds refreshed and nourished, you can now focus on cultivating the perfect environment for your tomato plants.

Choosing the perfect tomato for you

With countless tomato varieties available, selecting the right one can be overwhelming. But fear not! Consider what you love most about tomatoes – sweet and small for salads, or large and hearty for sandwiches? South Africa’s diverse climate means there’s a tomato for every palate and purpose. Research different types and find your perfect match.

Understanding tomato types

  • Determinate tomatoes: These compact plants produce a concentrated harvest over a short period. They’re perfect for small spaces and those seeking a quick yield.
  • Indeterminate tomatoes: These vigorous vines continue to grow and produce fruit throughout the season. They require more space but offer a continuous supply of tomatoes.

Nurturing your tomato plants

Preparing your soil

Growing tomatoes requires rich, well-drained soil. Before planting, enrich your soil with Wonder Organic Vita-Boost for better drainage and soil structure. Calcium is vital to prevent disease. Consider adding crushed eggshells, Wonder Dolomitic Lime and Wonder Root Builder Bone Meal to your soil.

Spacing your plants

To ensure your tomatoes grow strong and healthy, give them enough space. Plant them approximately 75 centimetres apart. Smaller varieties can be planted slightly closer together.

Watering and feeding your tomatoes

Tomatoes prefer moist soil but dislike wet leaves. Avoid overhead watering to prevent fungal diseases. Gently water the base of each plant, creating a small basin to retain moisture. Mulching with organic materials like compost or straw helps conserve moisture and keeps roots cool. Water deeply and regularly, especially during flowering and fruit development. Feed your plants with Wonder Plant Starter All Purpose to support vigorous growth and consistent fruit.

Overcoming common challenges when growing tomatoes

Even experienced gardeners encounter problems when growing tomatoes. Common pests like whiteflies, aphids, and American bollworm can be troublesome. Regularly inspect your plants and use appropriate insecticides when necessary. To prevent blossom end rot, ensure your plants receive adequate calcium by incorporating Wonder Dolomitic Lime or Wonder Root Builder Bone Meal into the soil.

Planting and harvesting for maximum yield

Time your planting

In South Africa, the ideal time to start growing tomatoes and sowing seeds is between August and January. For an early start, nurture seedlings indoors before transplanting once the soil warms up and the last frost has passed. You can typically harvest your first tomatoes around 80 days after transplanting. Some varieties offer a longer harvest period, allowing you to enjoy homegrown tomatoes for weeks.

Planting techniques

When transplanting your tomato seedlings, bury them deeply so the lowest set of leaves is at soil level. This encourages a robust root system. For a continuous supply of fresh tomatoes, consider succession planting. Plant a batch of tomatoes, then sow another two months later.

Maximising sunlight

Tomatoes are sun-loving plants. Ensure your plants receive at least six hours of direct sunlight daily. South Africa’s continuous sunshine is ideal for cultivating healthy, productive tomato plants.

Enjoying your harvest

There’s nothing quite like the taste of a homegrown tomato. Watch for the perfect moment when the tomato starts to change colour – it’s ready to be picked and savoured.

Preserving your tomatoes

South Africa’s bountiful tomato harvest offers a fantastic opportunity to enjoy these delicious fruits throughout the year. Here are some popular preservation methods:

  • Tomato sauce and paste: This is a classic way to preserve tomatoes. You can make your own sauce or paste or use a pressure canner for a longer shelf life.
  • Tomato jam and chutney: Sweet and savoury tomato jams and chutneys are delightful accompaniments to cheese and crackers or as a condiment for meat dishes.
  • Tomato drying: Drying tomatoes is a simple method that produces concentrated flavour. You can air dry, oven dry, or use a dehydrator. Dried tomatoes can be stored in airtight containers for several months.
  • Pickling: Pickled tomatoes add a tangy flavour to salads, sandwiches, and other dishes. You can pickle whole tomatoes or sliced tomatoes.
