Quick Overview

Climbing courgette varieties

For vertical cultivation in a pot or raised bed, you need to choose a zucchini variety that forms tendrils and grows in a creeping manner. Not every zucchini variety does this. Here are some examples of varieties that you can grow with a climbing aid:

  • ,Tromboncino d'Albenga'
  • ,Black Forest'
  • ,Shooting Star'
  • ,Vert de Blanc'
  • ,Rugosa Friulana'
  • ,Cocozelle'
  • ,Erken'

Suitable climbing aids and trellises:

As zucchinis do not usually climb on their own, you need a climbing aid. You have various options for this. In most cases, you should tie the zucchini plants up to the climbing support, as they do not stay up on their own.

  • Bamboo sticks
  • Tomato spirals
  • Garden trellis or trellis
  • Trellis made of wood or metal
  • trellis net
  • Obelisk

Growing climbing zucchini vertically: Ideas for the balcony

If you don't have a garden or only have limited space, but still want to grow fresh vegetables, climbing zucchinis are an excellent choice. These zucchini varieties tend to grow creeping, form tendrils and can therefore be grown vertically. There are just a few things to consider to ensure that your own climbing zucchinis grow and thrive successfully, such as the choice of variety or trellis and tying them up. However, if the zucchini feels at home, you can harvest plenty of zucchinis even in a limited space and make optimum use of your space.

Planting zucchinis in a pot

Zucchinis thrive well in large pots or planters. However, you should definitely choose the right pot size so that it has enough space and nutrients. Choose a pot with a capacity of at least 40 to 50 liters or a diameter of 50 to 60 cm. You should also think about waterlogging when growing in a pot. Your pot should therefore have holes at the bottom and be well drained if necessary.

As zucchini plants are heavy feeders, you should fill the pot with nutrient-rich garden soil and compost. It is also advisable to fertilize weekly during the season with liquid organic fertilizers such as nettle manure. In order for the plants to produce fruit properly, they must be placed in a sunny and warm location with enough light. As zucchinis consist of a lot of water, an even water supply is very important. A layer of mulch can help to protect the soil in the pot from drying out, as this happens much faster in a pot.

Grow zucchini vertically
There are many ways to grow vegetables in a space-saving way. So don't be sad if you don't have a garden or balcony.

Planting zucchinis in the raised bed

Growing zucchinis in raised beds offers a number of advantages that can both make care easier and increase yields. Raised beds are usually well drained and well ventilated, which reduces the risk of root rot and mold growth. Zucchini plants are quite susceptible to mildew.

To save as much space as possible when growing zucchini plants, you can choose either bushy and small-growing varieties in the raised bed. Alternatively, you can choose a climbing variety that you can guide up climbing aids and grow vertically. This minimizes the space required and looks beautiful at the same time. When planting, make sure there is sufficient planting distance to other plants, regular fertilization and an adequate water supply. Especially in freshly filled raised beds, you can grow high-yielding plants such as zucchinis, as the nutrient supply is still high. You can find an example of a mixed crop planting plan with heavy eaters for the first year with your raised bed in the article. Otherwise, you risk leaching out unused nutrients with a low-yielding bed planting.

Our tip: In raised beds or pots, zucchini plants and especially their roots are exposed to temperature fluctuations. To ensure they are warm enough, you should only plant them outdoors when the soil temperature is constantly above 15 to 18 degrees and there is no longer any risk of late frosts.

Tendril zucchini varieties: an overview

There are many different varieties of zucchini, but not all of them are suitable for vertical cultivation. If you want to grow climbing zucchinis, you should look for varieties that grow climbing. It is important to know that zucchini plants do grow creeping with tendrils. However, most varieties do not climb themselves and therefore need to be tied up to a trellis for the whole thing to work well. When selecting zucchini varieties for vertical cultivation, it is important to choose varieties with strong tendril growth.

Climbing zucchinis: varieties for growing in pots

  • Tromboncino d'Albenga: An Italian variety with long, slender, slightly curved fruits and a mild flavor. It climbs well and is ideal for vertical cultivation.
  • 'Black Forest': A climbing zucchini variety that produces dark green, cylindrical fruits and grows to a height of around 2 meters. This variety is resistant to some diseases and grows well on climbing supports. Unfortunately, this variety is an F1 hybrid and therefore not reproducible and seedfast.
  • Shooting Star': A yellow zucchini variety with an aromatic flavor that grows up to 1.2 m tall. As it is also an F1 hybrid, you cannot obtain your own seeds here either.
  • Vert de Blanc: A French, climbing variety with green-white, slightly ribbed fruits and a pleasant taste.
  • 'Rugosa Friulana': A creeping, Italian variety with slightly ribbed, yellow fruits and a firm texture. It is well suited to vertical cultivation when supported by climbing aids.
  • Cocozelle': This variety is easy to care for and produces long, green striped fruits. It grows easily in containers and can grow up a climbing aid if you tie the zucchini plant up.
  • Erken': Seed-resistant, old variety with greenish-creamy white fruits. This zucchini variety grows slightly creeping and is very productive. Due to its growth habit, you can also grow this variety vertically as a climbing zucchini plant.

Climbing zucchini: location & soil

A sunny location is crucial for growing climbing zucchinis in pots or on the balcony. Zucchini plants need at least 6 - 8 hours of direct sunlight a day for healthy growth. You should also choose a sheltered spot to protect the plants from wind breakage (zucchini plants only have a shallow root system) and strong temperature fluctuations. They prefer fertile, well-drained soil. A high-quality organic vegetable soil together with compost is ideal for growing in pots.

Suitable climbing aids and trellises

As climbing zucchinis climb several meters into the air, climbing supports are essential if you grow your zucchinis vertically. They give the plants the support and stability they need to grow well. There are many different types of climbing aids, including cages, trellises and espaliers. Make sure that the trellis is stable and offers enough space for the plants to grow. Here are a few examples of what might be suitable as a trellis.

Bamboo sticks

Robust bamboo poles can be arranged individually or in a teepee shape to provide stable support for zucchini plants. They are lightweight, durable and environmentally friendly.

Tomato spirals

These spiral-shaped metal rods, which are often used to support tomato plants, are also ideal for climbing zucchini. They provide a stable structure on which the plants can easily grow upwards. However, you will need to tie the zucchini plants up.

Garden trellis or trellis

A garden trellis or espalier can be placed either against a wall or free-standing and provides a large-area climbing aid for climbing zucchini. Make sure that the trellis or espalier is strong enough to support the weight of the plant and its fruit.

Trellis made of wood or metal

These trellises are available in various sizes and designs and can be easily attached to pots or planters. They provide a stable structure for climbing zucchini to grow up and spread out. Make sure the trellis is weatherproof and sturdy enough to support the weight of the plants and fruit.

Growing vegetables vertically
In addition to zucchinis, you can also grow other cucurbits such as melons and pumpkins vertically. Choose the right climbing support for your garden.

Trellis nets

Climbing nets made of plastic or natural fibers can be attached to frames, poles or even balcony balustrades. They offer the climbing zucchini numerous opportunities to hold on and climb up. Make sure you choose a climbing net with sufficiently large meshes so that the plants can easily grow through it.


These conical, free-standing structures made of metal or wood are an attractive option for growing climbing zucchinis in pots or on the balcony. They provide a decorative yet functional climbing aid and can also serve as an eye-catcher in the garden or on the balcony.

Tying up zucchini plants - here's how

As soon as your zucchini plants start to grow, you should tie them up regularly. This will ensure that they grow along the trellis and don't fall down. To avoid injuring the plants, you should only use soft ribbons or cords. Wire or rigid plastic cords, which can injure the stems and leaves, are not suitable.

Now start attaching the plant to the trellis at regular intervals (approx. 20 to 30 cm) along the main stem. Do not tie too tightly so as not to constrict the zucchini plants. You can also support side branches and attach them to the climbing support. When tying, it is important to ensure that the weight is evenly distributed, otherwise the plant can easily be damaged.

Our tip: Tying the zucchini plants up enables better air circulation. This reduces the risk of diseases such as mildew and pests. Nevertheless, check your plants regularly for pests and diseases.

More climbing vegetables for the balcony

Once you've started growing vegetables vertically, you'll probably find that it's a great way to save space and get a bountiful harvest. There are many other vegetables that are great for growing vertically, including tomatoes, cucumbers, peas and beans.

Growing tomatoes on the balcony
You can also grow tomatoes very well on the balcony. Pole tomatoes also grow upwards in a climbing fashion and can therefore be grown with little space.

You can still grow these vegetable plants vertically:

  • Tomatoes: Hanging or climbing varieties (vine tomatoes) such as 'Tumbler', 'Gardener's Delight' or 'Sweet Million' are particularly suitable here.
  • Cucumbers: Choose snake cucumbers or smaller, bushy varieties such as 'Patio Snacker' or 'Mini Stars', which grow well on climbing supports or trellises.
  • Beans: Runner beans, such as 'Blue Lake' or 'Cobra', as well as fire beans, are ideal for vertical cultivation. However, you can also grow bush beans in pots on the balcony without any problems, but these varieties do not tendril.
  • Peas: Sweet peas or climbing peas, such as 'Sugar Snap' or 'Alderman', are ideal candidates for vertical cultivation on the balcony. Use trellises or nets so that the plants can grow upwards easily.
  • Pumpkins and melons: Smaller varieties of watermelons such as 'Sugar Baby' or the pumpkin 'Hokkaido' can be grown vertically as long as the fruit is adequately supported.
  • Nasturtium: This edible flower is not only decorative, but also an excellent climbing plant. It can easily grow along trellises or climbing supports, complementing vertical cultivation on the balcony.
  • Eggplants: Choose compact varieties such as 'Patio Baby' or 'Ichiban' and support the plants with stakes to keep them upright.

Strawberries. I planted frigo plants in the spring. Half of the plants are gone, the other plants are puny, the harvest was almost nothing. Is this normal this year (Schleswig-Holstein)? Not even the snails liked the plants.
