1. Choosing the right variety

For an urban garden, it is important to select tomato varieties that are adapted to small spaces and have a fast growing cycle. Some ideal choices are:

  • Cherry tomato: Perfect for salads and snacking, with high productivity.
  • Pear tomato: Excellent for sauces and stews, with medium size fruits.
  • Compact orchard tomato: Specific varieties that do not require much space and have a controlled growth.

2. Seedbed preparation and sowing

A. Choice of substrate
Use a light, well-drained substrate, ideal for germination. A good mix is seedling soil combined with worm castings and a pinch of seaweed compost, which will enhance seedling growth.

B. Seeding in seedbed

Place the seeds on the moistened substrate and cover them lightly. Ideally, maintain a constant temperature of 18-22 °C to promote germination and finally water with a sprayer to avoid displacing the seeds and maintain the humidity without flooding.

3. Transplanting and care during growth

When seedlings have 4-6 true leaves, transplant them to larger pots or to the urban garden plot. Some key tips:

  • Planting frame: Make sure to leave enough space between plants (about 50-60 cm) to allow for good root development and adequate air circulation.
  • Staking: Install stakes or cages to support the weight of the fruits as the plant grows.
  • Watering: Maintain regular watering, avoiding waterlogging. It is essential that the water penetrates well into the substrate and reaches the roots.
  • Fertilization: In addition to the initial substrate, use compost or liquid fertilizer every 2-3 weeks to replenish nutrients. The application of seaweed compost also helps to strengthen the plant and improve nutrient absorption.

4. Pest and disease management

Although tomatoes are relatively hardy, it is important to be aware of potential problems:

  • Aphids: Control these pests with organic solutions such as potassium soap or neem oil.
  • Downy mildew: Be sure to avoid excess moisture and improve ventilation between plants. In severe cases, use specific organic treatments.
  • Rot: Constantly check the leaves and fruit, removing damaged parts to prevent the spread of disease.

5. Tomato harvest and use

The ideal time to harvest is when the fruits reach a uniform color (red, orange or depending on the variety) and have a firm but juicy texture. A timely harvest not only guarantees a better flavor, but also stimulates the plant to produce more fruit.
