Sowing Marigolds: Outdoors and on the Balcony

Planting Marigolds in the Garden: An Overview

Marigolds (Calendula officinalis) are part of the Asteraceae family. The annual flowers grow upright but bushy and reach a height of up to 60 cm, depending on the location. You can recognize a marigold by its beautiful bright yellow or orange flower. The flowering period runs from June to October.

The Right Location

Choose a sunny location so that the flowers develop a bright, intense color. Marigolds also thrive in a semi-shady spot, but are then more susceptible to mildew. Marigolds prefer sandy to slightly loamy soils with not too much nitrogen. If there is an excess of nitrogen, it develops less stably.

Propagating Marigold

You don't necessarily have to preplant marigolds, as they grow quite robustly when direct sown. However, marigolds do not flower until June when direct sown outdoors. If you want to enjoy the beautiful marigold flowers for longer, you can propagate them on the windowsill. The seeds are sown from mid-March and kept evenly moist. Marigold seeds germinate at temperatures as low as 15 ° C/59 ° F and the seedlings usually appear after 10 to 20 days. Three weeks after germination, the young plants are separated and each is given its own pot. The plants can then be planted out in the garden in mid-May.

Sowing Marigolds in the Open Field

Generally speaking, marigold seeds germinate very reliably, provided they have been stored correctly and are not too old. The seeds can be sown in the garden or on the balcony between April and August. To do this, loosen the soil and remove weeds that could compete with the seedlings. Scatter the seeds over the area and lightly rake them in. Alternatively, you can also plant the seeds individually. Marigolds are light germinators, so they are not sown deeply and are only placed about 0.5 to 1 cm/0.2 to 0.4 in deep in the soil. To ensure that the plants have enough space later on, you should keep a planting distance of 15 cm/5.9 in and a row spacing of 20 cm/7.9 in.

Companion Planting With Marigolds: Good & Bad Companion Plants

In a Mixed Culture, marigolds are very pleasant companions and many gardeners like to plant them together with vegetable plants. Their roots release a substance that nematodes don't like at all and keep away. They are a good companion for almost any plant. Only invasive plants such as Jerusalem artichokes and the solitary lovage should not be planted next to marigolds. Marigolds complement a vegetable patch very well, as they have been used as a medicinal plant for a long time. Their petals can be eaten fresh in a salad or dried and used as a tea. Don't worry, if you cut off the flowers, new ones will form. The more you harvest, the more it blooms. The bright yellow flowers also attract pollinators and provide food with their blossoms. This encourages beneficial insects in the garden, which contributes to plant health.

Obtaining Marigold Seeds

To obtain your own seeds, leave the flowers on the plant. The fruits ripen in the flowers: the marigold seeds. You can simply leave the plant as it will self-seed and bloom in its former glory the following year. If you want to sow the marigold in a different place, you can cut off the ripe, dried seed heads in the fall and sow them the following year.
