The Benefits of Planting a Fall Cover Crop by Jennifer Verprauskus

When Fall rolls around and everyone starts to put their gardens to bed, there are a few things to consider before you say good bye to the garden until next spring. It’s during this time of year that we have the choice to either plant a fall garden or a fall cover crop. 
The fall garden is typically started at the end of July or early August but it can be planted into September and October. In early to mid-October, we can replant spinach, cilantro, arugula, asian greens, kale, and other fast growing semi-cold hardy crops. However, when I plan on planting this late into the Fall, I think about using a season extender, which is a structure that captures heat from solar radiation and warms the plants and soil inside the covering, such as low hoops, heavy weight Reemay, cold frames and much more.

Cicadas: The Sounds of Summer's Close by Carol King

Nothing signals that August is here like the sound of cicadas singing: they can be counted on to sing until frost. In fact, according to folklore, it's six weeks after the first song that a frost is possible. Here are some other interesting facts about cicadas:

Cicadas are essentially tiny violins with wings. The body of a cicada is similar to that of a violin or a guitar, in that much of it consists of empty, air-filled spaces that act like a resonating chamber and amplify the sound they generate. The loud noise we hear is the male's mating call—females are silent.

Cicadas are the loudest insects in the Southwest. Their mating call and response can reach over 90 decibels. That is as loud as a gas lawnmower or a motorcycle. 

Cicadas are super sneaky. Ever tried to locate a cicada you are hearing, only to find nothing there? Once you start walking to a tree they stop calling as soon as you get too close, making it even more difficult to find them.

Cicadas have enemies that are the stuff of nightmares. The female cicada killer wasp flies around,  finds a cicada, stings and paralyzes it, and carries it to a burrow, lays one egg on it, and then closes the burrow up where the larva proceeds to feed on the victim.

There are 26 species of cicadas native to Colorado. The most common one along the Front Range is the Dog day cicadas (Tibicen dorsatus, T. dealbatus), the largest cicadas found in Colorado. They may be upward of two inches long. Their common name is derived from the males’ piercing call, which is often heard in the so-called “dog days” of mid-summer.

Harvesting and Enjoying Sunflower Seeds By Joyce D’Agostino

Sunflowers are one of the most popular and recognized parts of American gardens. In addition to their bright beauty, they attract beneficial insects. Some species produce seeds that are not only a great snack but have good nutritional value.

This time of year, most sunflowers are in bloom and some are already producing their dried discs of seeds. There are several varieties of sunflowers now available to the home gardener. These include pollenless flowers that have been developed for cutting bouquets. This type does not shed the yellow pollen onto furniture or cause issues for those with pollen allergies. There are dwarf varieties, also preferred for flower bouquets, as well as specialty color combinations.

Proper Soil Drainage Helps During Monsoon Season By Joyce D’Agostino

Gardeners in the front range of Colorado often find themselves during the summer growing season with hot temperatures and little rainfall or watering restrictions. This month we experienced the opposite effect with monsoon effect storms. While the moisture is welcome, often these storms produce very heavy rain in short periods of time supersaturating the soils and can include high winds and hail.

Preserving Herbs by Donna Duffy

One of the joys of summer cuisine is the addition of fresh herbs. Fresh herbs are showing up at the Farmers Markets, and many are ready to harvest in home gardens. As a general rule, herbs grown for their leaves should be harvested before they flower. For most herbs, the best time to pick is early in the morning just as the dew evaporates, but before the heat of the day.  Herbs can be used fresh from the garden or dried and enjoyed later. Following are tips for preserving and storing herbs.

Growing Your “Third Season” Crops By Joyce D’Agostino

By now, many gardeners are enjoying the bounty of their warm season vegetables such as tomatoes, green beans and cucumbers. However we do know that these vegetables do not tolerate frosts well and their production will be done in the fall.

If you would like to continue to harvest into the fall, there is still time to plant a few hardy garden crops. Many of these vegetables are very nutritious and will help extend your garden harvests even after some frosts.

Kale and collard greens are very cold tolerant and can be planted now. Be sure to review the attached bulletins for suggested varieties. You will want to choose those that do not take more than about 60 days to maturity, to allow them to produce before the killing frosts. For the best results, choose those that have been tested in our area for best production, hardiness and flavor.

Many cold season tolerant plants such as the brassicas and collards tolerate light frosts and in fact the flavors are enhanced when they are exposed to a light frost. As you can see in the kale bulletin below, it is recommended to plant kale in the front range area in the fall rather than in the spring to get the sweetest flavor and texture. There are a few other favorites such as radishes, carrots, lettuce, spinach and turnips that also tolerate cooler weather and in fact with some protection may continue to produce well into the late fall.

For more information about growing cold tolerant vegetables and extending your garden production, see the bulletins below:

Cheers to Your Plants! by Carrie Garczynski

Photo courtesy Horticulture magazine
Have you experienced hints of raspberry, swirls of lily, or essence of grass? Yes, in your yard, and perhaps in your favorite bottle of wine. Anyone who drinks wine probably has oodles of wine corks! What do you do with all of them? And what do corks have to do with gardening? 

Well, corks are hand-harvested and made from the cork oak trees Quercus suber from Spain and Portugal. They don’t soak up water, do not rot, are impervious to air, and can mold into the contour of any container.
