ZINNIA - Choose, sow, plant, care

Zinnia, beautiful erect annuals ...

Zinnias do not leave you indifferent. There are those who adore them and those who appreciate them less, who reproach them for an unnatural aspect, or too rough port and too "rough" leaves. Well.

Maintaining your kitchen gardens

Maintaining your vegetable patches is essential if you want to maintain a good yield from one year to the next, or simply succeed in growing your plants and vegetables.


Watering should be well dosed. Watch the weather forecast, if it rains you won't need to add water to your vegetable patch. Check your land regularly. If it is dry on the surface, you can water to moisten it. Never let it dry completely either. Again, there is no hard and fast rule, it’s your sense of observation that will make the difference.

Finally, avoid wetting the leaves as much as possible of your plants when watering. Indeed, the water that stagnates on the leaves can promote the development of certain diseases such as late blight on tomatoes, for example.

Also think about regularly clean the glass Ideally, keep a reserve or a water point near your vegetable garden, and if possible collect rainwater, which is better for plants than tap water.

Protect your plants from insects

Some insects can be harmful to your plants, especially if they proliferate too much. To keep them away, we strongly advise you to avoid any industrial chemical insecticide, for obvious reasons of toxicity for the fauna, the flora, and you!

Rest assured, there are many plants that naturally repel insects. You can plant a few between your vegetable garden plants, they will grow together without any problem. Here are some examples of insect repellent plants, some of which are well known:

  • Tansy
  • Lemongrass
  • The Basilic
  • The fragrant pelargonium
  • Petunia
  • Lavender
  • Nasturtium
  • Rosemary
  • Lemon balm
  • Absinthe
  • Mint (beware, mint is an invasive plant!)
  • Lemon verbena
  • Etc.

Generally speaking, insects do not like plants with a strong odor, which is why in the above list there are a lot of aromatic plants. The simple fact of plant basil or rosemary will suffice to protect your vegetable garden from pests, while providing you with fresh herbs to season your dishes.

There are also solutions for certain species that are harmful to the soil. In principle, with a vegetable patch you will not have this problem. However, remember that the coffee grounds and crushed eggshells, arranged at the end of the mulch on your vegetable garden, will prevent these crawling animals from coming to eat your salads!

Maintenance of the land

Crop rotation

In order for the soil in your square vegetable garden to retain its nutritional properties, it is essential to carry out a crop rotation year after year. In other words, not to always cultivate the same plants on the same surfaces. Even on a single vegetable patch, which will be divided into several smaller squares anyway, be sure to vary the fruits and vegetables you plant.


In a vegetable patch, you must regularly ensure that your soil contains the nutrients your plants need, and in the right quantities. Most of the “nourishment” of the soil is done in autumn and winter, while waiting for spring sowing. Favor as much as possible natural fertilizers ! There are plenty of them and their effects are as effective, if not better, than chemical fertilizers. Natural fertilizers can appear in different ways:

  • Some plants that are placed between the plants in the vegetable garden and allowed to decompose so that they provide nutrients to the soil (lettuce, lentils, etc.)
  • Compost, humus, some mulchings also provide nutrients when broken down by the fauna present underground
  • Natural fertilizers that are easy to make yourself and are very powerful, such as nettle manure (dilute to 10% when using it, and apply sparingly!)


Mulching your vegetable garden, summer and winter, has several advantages:

  • In summer, this allows protect the floor from direct sunlight, which can damage it
  • By using certain types of mulch, you keep some pests away.
  • In winter, mulching protects the floor from the cold, and helps regenerate for the spring, again preserving the wildlife there, which helps produce the nutrients your plants need to grow.

For your mulching, you can use all kinds of materials, as long as they are natural: straw, wood chips etc. You can choose them according to their aesthetics, their advantages, or both.

  • Type: flower and flowering plant
  • Height: from 0 to 30 cm, from 30 to 60 cm, from 60 to 80 cm, from 80 cm to 1 m, from 1 to 2 m
  • Flower colors: red, white, pink, yellow, orange
  • Desired exhibition: sunny
  • Soil type: well drained, humus
  • Sanitizing: no
  • Varieties: zinnia elegans, zinnia acerosa, zinnia violacea, zinnia citrea, zinnia maritima.

Attached to the genus Zinnia which includes around twenty species, the zinnia is a flower belonging to the asteraceae family, known for its long flowering stems and for the multitude of colors that its varieties offer. Native to Mexico and the southwestern United States, zinnias love warm, sunny regions where they can thrive and offer their flowers with white, yellow, red, orange, pink or purple petals, all on a height. up to one meter depending on the species.

This bushy plant annual is ideal for brightening up flower beds, planters, borders or pots in a garden as well as on a terrace or balcony. It flowers abundantly all summer long, and the decorative effect is guaranteed if the varieties are mixed to obtain different shapes and colors. The tall varieties of zinnias can also be cut and put in a vase, where they hold very well.

To note : if you want to mix them with other flowers in a bed, know that zinnias go very well with volubilis, marigolds, Indian roses and nasturtiums.

The But is a fast growing plant, but requires some care. Sowing is done in "pockets", that is to say three or four seeds together, in loose soil and in holes 2 cm deep. The pockets are spaced 25 cm apart. It is necessary to maintain moist soil until the first shoots appear. When the young seedlings have 3-4 leaves, keep only the most vigorous of the pocket: this is called thinning. Also remember to butter (= bring back the soil) at the base of the stems after a month and a half.

Hoe on the surface regularly to keep the soil cool and stop the growth of weeds. Mulch and water to keep the soil cool but not soggy.
