10 types of vegetables and fruits that grow well on the rooftop of a townhouse

1. Water spinach

Because of its easy germination, easy growth and development, water spinach is often grown in foam boxes. Tools for growing water spinach in foam boxes include: foam trays, composted coconut fiber treated with microorganisms, nutritious soil, and water spinach seeds.

After the vegetables are planted in the foam box, you need to regularly use a water sprayer to water the soil, ensuring that the soil is always moist. After only about 40 - 50 days of planting, the vegetables will reach a height of about 35 - 40 cm and then they can be harvested. After the first harvest, add fertilizer about 20 - 25 days later and harvest the second time. If you take good care of the water spinach and provide enough nutrition, you can harvest 5 - 6 times.

2. Cruciferous vegetables

The cruciferous vegetable family contains a lot of vitamins, and each season of the year has a variety of cruciferous vegetables suitable for planting. Therefore, cruciferous vegetables are always chosen by many urban households as the choice for growing in Styrofoam boxes.

If planting cabbage by tree, dig holes 20 - 30 cm apart, each hole 10 - 15 cm deep. Put a handful of composted manure or vermicompost, or biofertilizer in each hole. Plant 4 - 6 cabbage plants in each hole in a styrofoam box.

Before planting cabbage, you should pay attention to carefully preparing the soil, loosening it, and adding lime to kill pathogens. After planting, you must water immediately, once or twice a day, you can water directly at the base until the plant takes root, then only water when the soil is dry. Note, the styrofoam planting box must drain well.

3. Malabar spinach

Dishes made from Malabar spinach help cool down and refresh the body on hot summer days. Moreover, this vegetable is easy to grow and care for, so it is commonly grown in many families.

Malabar spinach is a light-loving plant, so you can choose a plot of land close to the outside wall with regular sunlight. For urban houses, you can grow Malabar spinach in plastic pots or foam trays on the balcony or terrace.

When the vegetable has 3-4 large leaves, you can trim the leaves to eat. After each harvest, Malabar spinach needs to be supplemented with a layer of nutritious soil and fertilized with processed cow manure.

4. Lettuce

This vegetable is not too picky about the soil, just need the soil to drain well and not get waterlogged when watered. Unlike the vegetables above, lettuce usually only likes shade and moderate sunlight.

Lettuce seeds have a thin shell so they do not need to be soaked like other seeds, they can be spread directly on the surface of the pot. Then cover the soil on top, add a little water to create moisture for the seeds to germinate.

When the lettuce has grown seedlings and has 2 pairs of leaves, plant them in pots or foam boxes; plant 10 cm apart, and 15 cm between rows.

Water the plants regularly twice a day in the early morning and cool afternoon; fertilize with organic fertilizer twice while the plants are growing;After about 35 days the vegetables can be harvested.

5. Amaranth

Amaranth is very easy to grow, does not need much care, just water enough for the plant to have enough moisture to grow. In the dry season, you need to pay attention to watering a lot to keep the soil moist. Water the vegetables twice a day in the morning and cool afternoon.

For vegetables to grow well and have high productivity, it is necessary to fertilize with manure, a mixture of nitrogen, urea, potassium or NPK diluted with water to water the vegetables periodically every 10 days.

All types of amaranth such as rice amaranth, white amaranth, red amaranth or purple amaranth are ready to harvest within 25 - 30 days after planting. If you want to eat young vegetables, you can harvest at the stage of sowing amaranth seeds for 3 - 4 weeks.

6. Tomatoes

This is one of the vegetables that is suitable for growing on the terrace, because tomatoes do not always need a large space to grow. Tomatoes can grow well even in hanging baskets, containers, plastic pots on the windowsill and many others; suitable for growing on the terrace in all seasons of the year.

Because tomatoes are climbing plants, when planted on the terrace, avoid areas with strong winds to avoid knocking over or breaking the plants.

When the tree begins to flower, you can add organic fertilizer to support its growth and fruiting... Although it is a sun-loving plant, it should be covered because direct sunlight is too harsh and will not be good for the tree.

7. Carrots

Eggplant is a suitable vegetable to grow on the terrace because the plant loves light, just need enough light to grow and develop well; can be grown in foam boxes or small wooden boxes; choose loose soil with coconut fiber and burnt rice husks to grow; each pot or box should only grow 2 -3 plants to give carrots room to grow.

8. Cucumber

If you want to create shade for your terrace and have fruit to eat, cucumbers are a perfect choice. This climbing plant only requires a pot, a styrofoam box, and a few dry plants for them to climb. More elaborately, you can create a trellis with wire for the cucumbers to grow.

Cucumbers need to be grown in pots or containers that are slightly larger than other vegetables; the pots should be placed in a place with plenty of light. Because they require a lot of water, they must be watered regularly, especially when the plant is flowering and fruiting; on hot summer days, they need to be watered twice (early morning and late afternoon).

Cucumbers grow very quickly, after a few days of planting you will see the growth of the plant clearly. You should harvest the fruit when it is still green, when it turns yellow it will taste bitter.

9. Green beans

Growing green beans does not require soaking and incubating the seeds; need to choose clean soil in a plastic tray or foam box about 15 - 20cm thick; sow seeds evenly in the tray about 20 - 30gr of seeds/tray. Cover the surface with a thin layer of clean soil and then water to keep it moist. After sowing, cover the seeds tightly with cardboard for the first 2 days for the seeds to germinate. Water twice a day, in the morning and cool afternoon.

Because green beans have large leaves and a high transpiration coefficient, the soil must be kept moist regularly, especially during flowering and fruiting. At this time, the soil moisture needs to be 70% constant.

Start harvesting 50 - 55 days after planting; should be harvested when the fruit skin is smooth green, if left to ripen the fruit will be hard, fibrous, poor quality and not tasty.

10. Squash

Zucchini is a light-loving plant and cannot survive in cold soil. Therefore, it should be planted when the outdoor temperature reaches at least 23 degrees Celsius.

The plant thrives in areas that receive plenty of sunlight, with ample space for the roots and leaves to spread freely. Choose a location that receives at least 6-10 hours of sunlight per day, without shade. Make sure the pot has drainage holes, the plant prefers moist soil but if it is soggy or waterlogged, the plant will not grow.

To produce fruit, the tree must go through a pollination process. If there is a lack of supporting insects, manual intervention is required, byPick a male flower (usually has a long, thin stem) and rub it against the pistil of a female flower (usually has a short stem)...

When the squash reaches about 10 cm long, it is ready to harvest; use a knife or scissors to cut off the stem.
