There are many plants that are suitable for planting in flower boxes. Of course, some do better than others. It is important that you choose strong plants that do not need too much space to grow. Flowers that bloom for a long time are logically better, this way you ensure that your flower boxes do not become bare again too quickly.

Summer is the season of colour in your garden. We all enjoy lots of colourful flowers and plants in our garden. With the help of flower boxes and pots, it is possible to grow plants in places where you would normally not be able to place them, such as your terrace. But which plants are the most beautiful and the most suitable for growing in flower boxes or flower pots? I will list the best plants for you.

Which plants are the best?

There are many plants that are suitable for planting in flower boxes. Of course, there are some that do better than others. It is important that you choose strong plants that do not need too much space to grow. Flowers that bloom for a long time are logically better, this way you ensure that your flower boxes do not become bare again too quickly. Below I have already listed my favourites:

- Hanging petunia: Annual - flowering period April to October - Sun - White, blue, red, pink, purple and multi-coloured.

- Lobelia: Annual – flowering period June to October – Sun, partial shade – White, blue and purple.

- Violets (Viola): Winter hardy – flowering period April to September – Sun, partial shade – White, blue, red, pink, purple, yellow, orange and multi-coloured.

- Balloon plant (Platycodon): Winter hardy – flowering period June to August – Sun – White, blue and pink.

- Bacopa (Sutera): Annual – flowering period May to October – Sun, partial shade – White, blue and pink.

There are many more flowers that are perfect for planting in flower pots. Go for nice combinations with different colours or choose different flowers with the same colour to keep it simple and sleek. You can also choose to put only one type in your flower pot, the Hanging Petunia is a good example of this. This takes up the entire flower pot and, as the name suggests, hangs over it, creating a beautiful flower bulb.

You can also use evergreen plants such as ivy (Hedera) between your flowers to fill your flower pot or planter a bit more and to make the colours of your flowers stand out even more.

Ornamental grasses also look beautiful in a flower pot. In addition, they are also super easy to maintain and fit on any terrace. You can even combine them with other plants.

Tips for planting your flowers

Choose a flower box with drainage holes, so that excess water can drain away properly.

- Use potting soil for flower boxes, this stays moist for longer and contains nutrients so you do not have to add fertilizer immediately.

- Choose plants that need the same conditions. A plant that needs a lot of sun should not be placed next to a plant that cannot tolerate much sun.

When to water plants in flower boxes?

Plants in flower pots will have to be watered slightly more often than plants in the open ground. It depends a bit on the type of plants you have and the weather, but once a week is definitely not an unnecessary luxury. If it doesn’t rain much and it’s very warm, you may even have to water every day. A general rule: make sure the soil around the plant is soft and that the water stays. Then the soil is saturated.

The best time to water is in the morning or in the evening. It is still cool so that the water does not evaporate too quickly and the plant has a long time to absorb the water. Never water your plants during the warmer times of the day. The water will evaporate too quickly, so that the plant does not have time to absorb it and the leaves of your plant can also burn.
