Q. Longevity of chrysanthemums. I am heartbroken because white mums bred by the U of MN did not come back as bountifully as every yea

r since 1971. Other bushes are from abt. 2001. I know we’ve been lucky but I don’t know the reasons why this year most of the pl ants are left as dry sticks. Now an animal is pushing down the last surviving plants, breaks off the stems and leaves leaves on the soil.
We’ve never seen deer around. Could these be rabbits or squirrels? If I would send you photos how huge my chrysanthemum bushes were still last year, you would be surprised. I will try to still find verbena and coneflower plants and impatiens to help repel. Deer and dog repellents did not help.
We are often absent at the height of the summer. Maybe last summer, my mums did not get enough water I also last winter did not cut down the branches and wilted flowers. What did I do wrong>
Thanks for any suggestions.

Squirrels, Chipmunks, mice, Voles, Moles...all possible reasons for plant injury.
Mums can tend to be short lived and it may not be anything you have done other than the age of the plant.

Q. Watering Mums

Following advice to water each plant with 1″ of water – how would I measure that 1″?

A.

Adding an inch of water applies only when there has been less than an inch of rain. If there has been rain in the preceding week, subtract that amount from 1.0 inches. An inch equals 16 gallons per square foot which is a lot. If using a sprinkler or soaker hose, sink a tuna or pet food can with straight sides until it is level with the garden soil. Time how long it takes to reach one inch; this may be several hours by soaker hose. As temps cool and days shorten, the plant needs less water. The soil should be dry down 1.5-2 inches before the next watering. Weekly is an average. Temps over 85, sandy soil, large plants and windy weather increase the need for water. If your soil is heavy clay, it will hold water longer than loam or sandy soil. Certainly, the soil should not be mucky or wet. Damp soil is what you are after. By watering heavily once a week or so, you encourage the roots to go deeper into the soil; this is important for long-term survival. If your plant is in a container, water when the top 1 inch of soil is dry. The one inch recommendation is for plants in the ground in average soil.

Q. Why did my fall mums turn brown and quit flowering?

I purchased large, beautiful mums in August and now they quit flowering and the new buds are turning brown before they open.

The mums that are often sold in autumn and are covered in blooms are highly cultivated and forced into that abnormal bloom. It seems to leave the plant exhausted. In addition, these mums are often not hardy. They are treated as annuals and tossed onto the compost pile when their glory fades. Try dead-heading and fertilizing to coax more blooms. If you have planted it, put 3-4 inches of wood mulch over the crown once the ground freezes. If still in a container, try over-wintering in a garage. Don't let it dry out as this kills the plant for sure. A gentle watering on Thanksgiving, New Year's, Valentine's Day and Easter should be sufficient. The link that follows goes to an article on container mums. https://www.gardeningknowhow.com/ornamental/flowers/chrysanthemum/growing-mums-in-containers.htm

Q. My fall mums are dying

Good afternoon! I bought some beautiful fall mums a few weeks ago and the yellow buds have started turning brown. I’ve been watering them daily and they sit on my front porch (partial sunlight – they get some direct sunlight in the afternoon). I attached a photo – does it took like they need more sunlight or water? They were so lovely when I first got them, it’s a shame they seem to be dying. Thanks so much! -Laura T.

They need 4 hours of sun daily. However, you can prolong bloom by giving it bright indirect light instead of full sun.

They do need plenty of water, but try watering thoroughly then waiting till the top of the soil is dry to water again. Daily may be too much. Make sure the pot is draining well.

Go ahead and cut off the brown buds. Also, inspect the plant for pests.
