Here is another of my favorite annual flowers for great all-summer color.  Gerbera daisies are a very easy plant to grow.  I enjoy the “happy” look of their flowers which just keep coming all summer. The color range covers everything but blue. In previous seasons the only plants available for...

As we transition from winter to spring, we have to anticipate some variability in our weather and temperatures.  A couple of really warm days and some folks are ready to plant potatoes. But the calendar is a better indicator than our emotions.  None of us has the crystal ball, but the law of...

I have finished my hibernation! It amazes me that when we finally get to see the sun in the morning after weeks of cloudy weather, we realize that our daylight hours have increased dramatically. That mean it’s time for gardeners to get to work ... that means me, and I’m loving it! If you have...
  If you have been “vacationing” indoor plants outdoors for the summer, now is the time to begin to acclimate them for their return to indoor conditions.  The houseplants have been used to summer’s long days with light coming from all around them, but indoors they will have to adjust to what...
  These early autumn days of a really warm daytime temperature and a cool night are ideal for flowers to develop their best color. At this time, planters are full to overflowing with growth, and that much foliage requires a lot of water and food to keep the color coming strong. Many of my pots...
  I just walked over to some of my shrub roses and was shocked to see that black spot had attacked with the intention of taking off every leaf!  This summer has been ideal weather for every form of blight and fungus because of our high humidity and the onset of dew lasting from dust through mid...
  I had a friend ask me what it would take to make a Christmas cactus bloom. Their plant was several years old and was a large plant but it never produced a single flower. Christmas cactus, like a poinsettia plant, initiate flower buds when the days get shorter and the nights get cooler in late...
  It just seems like many crops are maturing earlier than they normally would. However, when I look back in my archive of garden advice, we’re not too far ahead of a typical season. Summer always becomes a blur because we have waited so long for it to arrive and then we’re back to facing another...
  Two years ago Corrine and I attended a seminar in Fairmont for small fruit growers facilitated by the University of Minnesota staff. He mentioned a new fruit fly that was already confirmed in Rock County. Drosophila has moved east from California since it was discovered in 2008 and is now a...
  It is August … already! This is the month to transplant, move or thin our German bearded iris. The plant will continue to grow in the direction the rhizome is pointing, so keep that in mind when you are replanting them so that someday you won’t have to move the house to make room for the iris....
