Taxonomy
Description
Preparation
- Asters make a good cut flower for fall arrangements. Cut the flowers late in the evening to avoid contact with avid bee visitors. Take stems when about 1/5 of the flowers are open for the longest vase life.
Culture
- Choose an area with full to partial sun for your plants. Too much shade will cause lanky plants. Asters appreciate soil on the slightly acidic side, with a pH ranging from 5.8 to 6.5. If your soil is alkaline, you can correct it by adding organic matter such as well-rotted manure, leaf mold, or compost. Although asters are common in garden centers in the fall, when they are visually appe…
Prevention
- Gardeners often blame the death of an aster the following year on hardiness issues, but many asters perish over their first winter due to heavy soils and poor drainage. If you have heavy clay in your flower garden, plant your asters in raised beds or consider double-digging the soil. Most insect pests leave asters alone, but lace bugs can be a bother. You're more likely to notice the da…
Cultivation
- Asters are moderate feeders, and they appreciate a balanced flower fertilizer given twice a month from spring until the blooms begin to open. Excessive nutrients can shorten the blooming time, so stop fertilizing asters in August. As is the case with many flowers with wildflower heritage, asters are somewhat drought tolerant; certainly more so than...
Management
- Rust and powdery mildew disease can affect aster foliage. Follow proper plant spacing to improve air circulation, and avoid overhead watering to prevent these problems.
Features
- Because asters and mums bloom at the same time, you can plan several attractive garden schemes with these two fall perennials. Plant blue asters beside yellow mums; these opposites on the color wheel pop. Combine purple asters and white mums in a garden container. Pair the dainty blooms of a pink aster variety with the larger double flowers of a pink or purple mum for textural …
Uses
- Some people are surprised to learn that the aster is an edible flower. As such, they are welcome members of the vegetable garden, where they will draw bees to pollinate the end of the season harvest. Sprinkle fresh aster flowers in salads, or use the petals as a finishing garnish on cooked meats or vegetables.
