Orchids are some of the most exquisite flowers you can grow in your garden, and winterizing orchids is an essential part of their maintenance. The colorful blooms can do wonders to spruce up your yard during the spring and summer. However, the plants do not do well in the winter if you live in a region that sees four distinctly different seasons. You will have to take measures to winterizing your orchids to ensure they stay healthy and will thrive again once the spring returns.
The first thing you should do to winterize your orchids is to cut back on watering them. The cooler the temperature becomes, the less water you should give it if you leave the plants outdoors. However, if you dig your orchids up and replant to store them in your house, you will have to water them more often than usual. In this instance, you should also keep the plants in a warm, humid room. If you are storing your orchids in the garage or shed for the winter, make sure the temperature remains between 30 and 40 degrees Fahrenheit.
Cut back on fertilizing your orchids. You can apply fertilizer only on an occasional basis to aid in setting the flower spikes, but otherwise, this should be kept to a bare minimum.
When you move your orchids indoors during the colder months, make sure to give them a good amount of sunlight. This means you should place them on a windowsill in a room in your house that gets a good amount of sun. If you are keeping the plants in a greenhouse, you should cover them with shade cloths so that they can receive some sunlight and partial shade. Of course, this is also dependent on the variety of lilies you own, as some require much more sunlight than others.
If you are leaving your orchids in the garden for the winter, putting stakes around them will help to keep them upright. This will also protect them from cold winds. Avoid doing this while the plant's spikes are maturing, as this will cause the spikes to grow in strange angles.
