Planting Broccoli, Cabbage, and Cauliflower in the Home Garden


Broccoli, cabbage, and cauliflower are members of the cabbage family.  They are also referred to as cole crops.  Cole crops are cool season vegetables which grow best at temperatures between 60 and 70 degrees F.  When planted in spring, these crops produce high quality heads before the arrival of hot summer weather. 

Brown Marmorated Stink Bug Update


The brown marmorated stink bug (BMSB), Halyomorpha halys is becoming more well-known as it appears in more and more counties around the state and in more and more homes in the counties where it was previously reported. 

BMSB was first reported in Iowa in 2011 and since has been reported in 23 counties.  We continue to document reports of BMSB in counties where it has not been previously reported.  See the map below and please let us know if you find BMSB in an unmarked county.

Dividing Perennials


The perennial flowers in your garden or landscape can be divided (split into smaller pieces) in order to control the size, to rejuvenate plants or to propagate (creatie additional plants).  Learn more about dividing perennials in the Iowa State University Extension & Outreach Yard and Garden news release from March 8, 2018.

Propagating Houseplants


Stem or leaf cuttings, slips, and air layering are ways for growing a new houseplant from an existing one.  Getting a new houseplant identical to your old houseplant is usually an easy procedure but there are details that must be carefully followed depending on the species of plant.  Find tips for propagating your favorite houseplants in the Iowa State University Extension & Outreach Yard and Garden news release from February 21, 2018.
