What do asters do

I have a large aster plant in my new yard. It dried out and fell over this winter. Should I cut it to the ground?

Yes, you can cut off the dried out dead branches. This is normal for asters. As soon as the weather warms up you should see some new growth from the bottom of the plant. I just bought a pot of asters a week ago and the leaves started turning brown from bottom up. At first, I watered every 2 days.

When they start wilting, I asked the seller about it and he said to water everyday. So I watered every night. But it's not helping.

Need help urgently. Really don't want the Asters to die. Or I at least want them to last till the Chinese New Year. Thanks in advance.

You can start the seeds indoors during the winter by sowing seeds in pots or flats and keeping them in the refrigerator for 4 to 6 weeks to simulate winter dormancy. They need this period of colder weather to kickstart germination.

How to Grow Asters Add a thin layer of compost or a portion of balanced fertilizer with a 2—inch layer of mulch around the plants every spring to encourage vigorous growth. If you receive less than 1 inch of rain a week, remember to water your plants regularly during the summer. However, many asters are moisture-sensitive; if your plants have too much moisture or too little moisture, they will often lose their lower foliage or not flower well. Keep an eye out for any stressed plants and try a different watering method if your plants are losing flowers.

Stake the tall varieties in order to keep them from falling over. Pinch back asters once or twice in the early summer to promote bushier growth and more blooms. Cut asters back in winter after the foliage has died, or leave them through the winter to add some off-season interest to your garden.

Some gardeners say a layer of organic mulch will supply all the nutrients they need, while others suggest a light application of an organic fertilizer at the start of their growing season. Do not apply fertilizer once they have started blooming as it may shorten the bloom time.

Asters help to position cleavage furrows so that cytoplasmic division results in two evenly divided cells. The cell cortex is responsible for producing the contractile ring that constricts the cell and "pinches" it into two cells.

Cleavage furrow formation and cytokinesis are essential for proper development of cells, tissues, and for proper development of an organism as a whole. Improper cleavage furrow formation in cytokinesis can produce cells with abnormal chromosome numbers , which can lead to the development of cancer cells or birth defects.
