Pumpkins, corn stalks, and mums will likely be decorating our porches. Some people purchase mums every year and some have their mums come back every season. People often wonder if chrysanthemums are an annual or a perennial plant. Watch this video to learn more:
Late September through October is an excellent time to plant spring-flowering bulbs such as crocus, tulips, and daffodils. These plants need to develop roots in the fall and must meet a chilling requirement over the winter in order to bloom in the spring.
If your irises aren’t looking healthy this year, they may have a condition called bacterial soft rot. The bacteria will cause a smelly and slimy rot of the leaves and rhizomes. Leaves often separate easily from the rhizome. If your plants are heavily infested they may die.
Though most often associated with iris borer, environmental damage can also provide an entry point for this disease.
Rhizomes that show extensive signs of damage should be discarded. If there is a plant that has special value, you may wish to try to save it. The American Iris Society suggests using a spoon to remove all infected tissue. Then, allow the rhizome to dry in the sun. Finally, use a chlorine based cleanser to powder the wound. Dousing in place with Dial antibacterial soap (with triclosan) can be substituted for the chlorine based cleanser.
When dividing rhizomes from beds that have shown evidence of soft rot, disinfect the knife between cuts of even apparently healthy rhizomes with a 10% bleach solution or rubbing alcohol.
As mentioned previously, iris borer damage can provide a place of entry for this disease. To control iris borers, remove and discard dead leaves in the fall to eliminate a number of the iris borer eggs. Larvae can also be killed by hand in June by squeezing infested leaves in the vicinity of the injury. During division, borers in lightly infested rhizomes can be killed by poking them with a piece of wire. Borer control can also be achieved through the use of imidacloprid (Merit, Bayer All-In-One Rose & Flower Care, Bonide Systemic Granules, Hi-Yield Systemic Insect Granules) or through the use of the parasitic nematodes Steinernema carpocapsae or Heterorhabditis bacteriophora.

Christmas plants such as poinsettias, holiday cactus, and amaryllis bulbs are a fun way to bring some color to the winter months. They like a bright, sunny location in your home and regular watering. With proper care these plants can be kept from year to year for lasting value.
Is the thought of cold, winter days bringing you down? Fall is the best time to plant bulbs to have a pop of color in your landscape in the spring. Bulbs are often the first plants to make an appearance after a long winter and can be enjoyed with little effort and maintenance.

Nature always gives us signals as seasons change. When summer starts to shift toward fall, the leaves begin to change colors. Another sure sign that fall is right around the corner is the arrival of colorful and beautiful fall mums in garden centers.
Now is the time to plan how and where to use these plants effectively around your home and landscape. A newer trend for growers is to mix colors in containers, so be ready for even more decisions.
Watch this video for information on how to get your mums to last through the winter:
Sunflowers are usually ready to be harvested beginning in mid-September and into October. Seed heads can ripen on the plant, but they will need protection from birds. Try covering the heads with a paper sack or cheesecloth once the petals start turning brown. Use a twist tie or rubber band to secure the covering. This will not only help keep birds out but will prevent ripened seeds from dropping out of the head. Check for maturity by looking for the following signs:
– Florets in the brown center of the flower disk should be shriveled.
– Heads should have turned down.
– The backside of the head should be lemon yellow.
The ultimate check, of course, is to pull a few seeds to see if they have turned black with white stripes, the typical color. Empty shells usually indicate a lack of pollination earlier in the year. If heads are to remain uncovered, harvest when a few seeds start turning black and white. The flavor will not be good as when seeds are allowed to ripen on the plants, but fewer seeds will be lost.
Cut the heads and place in a paper sack. Some people prefer to cut the heads with about a foot of stem attached and hang them upside down in a dry, well-ventilated area. A paper bag or cheesecloth can be placed over the heads to prevent seeds from dropping as they dry. Seeds can be easily removed from dry heads by rubbing gently.
