We've all seen the standard daisy with elongated white petals and a bright yellow button center. Imagine a beautiful pink, white or red flower that looks similar to the center of a Shasta daisy, and you've got an English daisy. These lovely plants can grow so well in some locations that gardeners consider them nuisances. English daisies look best as edging plants or in rock gardens, since these flowers tend to grow in clumps. English daisies tolerate cool weather and thrive in rich soil and partial to full sun. Winterizing this plant requires careful attention to the weather, since English daisies often act very similar to an annual.
Care for the plants properly during the growing season. Clip off dead blooms to encourage foliage growth. Fertilize your English daisies with a high-quality organic fertilizer to improve their health during this important growth period. Water regularly, especially during the hotter times of the summer.
Continue watering your English daisies into the fall. Plants continue growth of their root systems even as leaves die off in preparation for winter dormancy. Keep an eye on the weather and assist your plants with a good watering if dry periods of more than 10 days occur during these months.
Decide if you prefer to prune the plants back for the winter or if you simply want the foliage to die off naturally. Two schools of thought exist on this topic. You can either prune back plants for a neat appearance in your winter garden. Some gardeners believe in simply allowing plant stalks to fall to the ground during winter to decompose. This allows additional nutrients to reach the soil in your garden. Either choice won't harm your English daisy plants.
Clip back plants (if you choose this method) to about 3 to 4 inches from the ground.
Apply a light layer of shredded bark mulch or shredded leaves around the base of the plants. If you've pruned the plants back, cover the stems with a layer of mulch. This layer of insulation retains moisture in the soil and limits the effects of freezing and thawing on the roots.
