Wintering daisies in the garden and in containers: what winter care needs popular flower?

Many people use daisies as bedding plants and throw them away at the end of the fall, but these pretty, semi-hardy plants can be protected for the winter and bloom again the next spring. Gardeners like daisies for their brilliant white flowers. In the garden, on the patio, balcony or front steps, they exude a cheerful, summertime flair that always comes with an air of neatness and tidiness. Their botanical name Leucanthemum, borrowed from ancient Greek, means nothing more than “white flower”. These flowers have some requirements for overwintering, and in our article you will learn how to overwinter daisies.

Wintering daisies in the garden

In autumn, it is customary to cut back the stems of daisies to 5 cm above the ground

If you have sown or planted one of the native daisy varieties, you need not worry about wintering in the garden – daisies can easily tolerate temperatures as low as minus 40 degrees. It never gets that cold even in the typical “cold regions” of Germany. If your daisies have the term Maximum or Superbum in their name, you should find out which winter hardiness zone these plants are intended for when you buy them. If you don’t yet know which winter hardiness zone your home is in, you should definitely find out with these hybrids.

At least if you live in one of the colder regions of Germany, you should take the precaution of helping these daisies through the winter with a little winter protection, such as a loose mulch compost blanket applied in late fall. Spread 5 to 8 inches of mulch over the flowers to protect them throughout the winter. Straw, leaves and pine needles work well.

Marguerites overwinter in the garden and in tubs - What winter care needs the popular flower.

The various hybrids of the garden or perennial daisies, with their names such as ‘Group Pride’, ‘Silver Princess’, ‘Alaska’ and ‘Polaris’ may well be a clue to pay attention to the winter hardiness attributed to them. In autumn, it is customary to cut back the stems of daisies to 5 cm above the ground, after the foliage has yellowed. You can also leave the dying stems in place to protect the plant during the winter. In this case, remove the dead shoots in early spring to make room for new growth.

Wintering the flowers in containers

Care is not complicated, the plants do not need much attention in the winter

If you have purchased or self-sown a variety of true daisies to keep in containers, moving them to winter quarters is always recommended. This is because even meadow daisies survive the worst frosts only because they can send their long taproots deep into the garden soil to areas that remain frost-free. They can’t do that in a tub. Also, the soil will freeze through much faster in a tub because the cold can penetrate from the sides as well.

You should not just “forget” the daisies in the tub on the balcony. Marguerites overwinter by being prepared to bring them indoors as soon as the first night frost comes. If the winter quarters are not ready and the first night frost is somewhat severe, this could be the end of the potted flowers.

The best winter quarters are winter gardens or greenhouses, where the flowers get plenty of light and can be kept at temperatures between 5 and 7 degrees. If such a room is not available, you should put the tubs in the room that remains the coolest in the winter and allows a lot of light.

As a precaution, you should help the flowers through the winter with a small winter shelter

Before moving to this cool room, as a rule, it is recommended to vigorously cut back daisies. You should cut away up to a third of the shoots. It would be ideal to cut at a time that gives the plant time to close its cuts. For example, you could use the late summer flowering break for pruning. Then the flowers will form a few new shoots for the rest of their time outdoors. They then move to the winter quarters without pruning.

However, there are gardeners who, if they overwinter their daisies, do not prune them back before moving, but wait until spring to cut them back . This could be an advantage when overwintering at the lower temperature limit, for example, with the foliage the flower carries some winter protection. It is also an alternative if you have not managed to cut back the flowers before the first frost. Daisies cut too late tend to dry out badly in winter, which is unsightly and makes new shoots difficult.

Care over the winter

You should not simply forget about the daisies in the tub on the balcony

Care is not complicated, the plants do not need much attention in the winter. Marguerite now does not get fertilizer and watering is greatly reduced. The colder the location, the more sparingly you should water. A little water every week or two will only prevent the root ball from drying out completely. A sign of overwatering is new shoots in winter, then you should keep the daisy drier. The flower is best given soft water, such as rainwater.

If the leaves on the daisy turn yellow or brown, you should remove them immediately. In the spring, the daisy is then carefully accustomed to more warmth by placing it in a slightly warmer and brighter place starting around March. During this transitional period, the flower gets a little more water and the first fertilizer. Only in May it is finally placed back in its summer location.
