Cytospora Canker on Spruce Trees by Melinda Myers , posted Sep 14 2012 5:05PM

Your blue spruce is just reaching maturity when suddenly needles start turning a purplish brown and eventually the branch dies. The problem may be Cytospora canker. A closer look will confirm your suspicions. Though this disease commonly starts on the bottom branches you may find individual branches dying further up in the tree. Cytospora canker infected trees usually have a bluish white sap on infected branches and the trunk. This fungal disease is most common on 15 year and older Colorado spruce. There is no cure, but the tree usually doesn’t die. You can usually help minimize the problem with proper care. Prune and destroy infected branches. Be sure to disinfect your tools with a 70% alcohol or 10% bleach solution between cuts. Mulch the trees to conserve moisture and improve the soil. And water thoroughly as needed during dry periods. A bit more information: And watch for new research and future control options. Scientists Gary Watson and Karel Jacobs found a tree growth regulator significantly reduced the disease occurrence on treated trees. So, good news may be on the horizon for our spruce trees.

We get your letters...
What an amazing weekend! First of all, a very big THANK YOU to everyone who came out to Grafton and Mukwonago and waited in line amid cold, windy and rainy conditions for those Wisconsin Dells Season Opener Cards. For me, it is a chance to meet / hang out with YOU the listener and give you goodies! Second, got this letter from our 99.1 The Mix Contact Us forum, from the Dawson family of Port Washington and was truly surprised that my "simple gesture" warranted the following... Question: Your Name: Answer: Michelle Question: Your City: Answer: Port Washington Comments: Yesterday I took my parents to Grafton to wait for season opener cards. It was quite a cold morning. We arrived at 10 because in the past there have been huge lines. My mother is recovering from a recent open-heart surgery. She is a very petite older woman. Van McNeil was interacting with people people in line and I asked him if it would be possible for my mom to going to the bank to warm up. He unexpectedly took my mom's hand and escorted her into the building. He was so kind to her and gave her a hug. He made sure she was warm and dry and took very good care of her. My mom and dad are thrilled to be going to the Dells. Unknown to Van my dad just got out of The hospital last Friday after 4 1/2 weeks of being in. It's been a very rough couple of months for my parents and their health. My mother was just beaming about how nice Van was. I wanted to thank you for the season opener cards which will allow my parents and my family to enjoy a vacation in Wisconsin this summer, and send a special thank you to Van for being so wonderful to my parents. You're welcome and THANK YOU Michelle! Just doing what I do because that's how my mama raised me! Enjoy the Dells! -Van #everylistenermatters

Perennial Garden Renovations
Give your tired perennial garden a boost without a total renovation. Topdressing your garden with compost every year or two provides most if not all the nutrients your perennials need. Pull back the mulch if needed. Then spread an inch of compost over the soil surface. You can buy a quality compost or make your own. Leave the compost on the surface or lightly mix it into the soil. The earthworms, ground beetles, and other organisms will take it from there – moving the compost into the soil and around the plant roots where it is needed. Or, do a bit of vertical mulching. Use an auger bit on your cordless drill. Simply drill holes into the soil between plants. Then fill the holes with compost. This gets the compost closer to the plant roots and soil organisms that will help mix it into and improve the soil. Soil preparation and repair will help transform your garden. A bit more information: Apply a plant strengthener such as JAZ spray to increase plant vigor and their natural ability to tolerate environmental stresses, insect attacks, and disease problems. These natural products aren't fertilizers or pesticides. They can be applied to established plants at the beginning of the season to boost their ability to deal with stress or as soon as problems arise.

Growing Banana Plants Indoors or Out
Add a bit of the tropics indoors or out with a banana plant. The large leaves are great for screening views and creating a bit of privacy on a balcony, patio or in the yard. Add a wicker planter or chair and you have your own tropical get-away. The fiber banana (Musa basjoo) is hardy in zones 5 to 11. It grows in full sun. It will die back to the ground and benefit from winter mulch in northern areas of its hardiness zone. Less hardy and smaller, the blood banana (Musa acuminata 'Zebrina'), has large leaves with red markings on 6 to 8 foot plants. It's only hardy in zones 10 to 11, but can be overwintered as a houseplant or allowed to go dormant in other areas. Combine these tropical beauties with palms, ginger and bird-of-paradise. Or add some hardy tropical look-alikes such as Japanese forest grass, large leaf hostas and trumpet vines. A bit more information: Push the limits of your growing region with special wintering techniques developed by Dr. David Francko, author of Palms Won't Grow Here and Other Myths: Warm-Climate Plants for Cooler Areas.

Preserving the Asparagus Harvest
Preserve the flavor and nutrition of asparagus to enjoy year round. This flavorful vegetable is low in calories and high in Vitamins A and C as well as fiber. Unfortunately, it is most readily available and at the best price in the spring. Insure the best flavor with proper harvesting. Select young tender spears 8 to 10 inches tall. Wash, remove the ends, and then cut to fit the freezer bag or container. Blanch the asparagus before freezing to lock in flavor, color and texture. Dip the asparagus into boiling water. You'll need a large pan with a lid. Blanch small spears for 2 minutes, medium spears for 3 minutes and large spears for 4 minutes. Remove and immediately set the blanched spears in ice water for 5 minutes to cool. Drain and freeze. And, if you don't have an asparagus patch, you may want to consider planting one this year. A bit more information: May is National Asparagus Month. For tips on planting and harvesting asparagus listen to my audio tip. And check out the National Center for Home Food Preservation website for helpful tips and guidelines for preserving your harvest.

Mexican Mint Marigold (Tagetes lucida)
Add a little color and flavor to your garden and salads with Mexican tarragon. This subtle beauty is really a type of marigold, but the leaves and flowers have a tarragon fragrance and flavor. Wait until after the danger of frost has passed to plant this zone 8 to 10 hardy plant. Grow it in full sun to part shade and well-drained soils. It is somewhat drought tolerant. Northern gardeners can treat it like an annual and those in the northern range of its hardiness zone may see it die back to the ground in a hard freeze. But don't worry its root hardy. The yellow flowers appear in late summer and persist through fall. The 14 to 20 inch tall plants make a nice addition to herb gardens and flowerbeds. Harvest the new growth to use fresh. Preserve the flavor by freezing the leaves or storing in vinegar. They tend to lose their flavor when dried. A bit more information: You can find this plant listed under several common names including Mexican tarragon, Texas tarragon, pericon, and sweet mace. No matter the common name you can use the leaves and blossoms in soups, sauces and chicken dishes as well as salads. Some gardeners even seep it for tea. Visit Bonnie Plants for more information and gardeners ideas for growing and using this plant in the garden. For more gardening tips, how-to videos, podcasts and more, visit www.melindamyers.com

Year of the Watermelon
Year of the Watermelon The National Garden Bureau has declared 2013 the Year of the Watermelon. Be part of the celebration and consider planting watermelon in this year's garden. Don't let the sweet flavor deceive you – these are nutritious as well as delicious. High in Vitamin C, low in fat and calories - it is a great way to boost your energy. Plus, all parts are edible. You can pickle the rind, eat the fleshy portion fresh or roast or grind the seeds for flavoring. In china they stir fry watermelon while the Russians often pickle it before eating. You may want to try some new ways of enjoying this tasty summer treat. Grow watermelon in full sun and well-drained soils. Save space by growing these plants on a trellis or decorative obelisk. Just secure the heavy fruit to the support with a cloth or macramé sling. Or plant a few seeds in a container and let the vines wander over your balcony or trellis. A bit more information: Try planting one of the large picnic-type watermelons that can weigh 15 to 50 pounds. These are sure to get everyone in the family excited about growing and eating this, the largest edible fruit in the United States. Or perhaps you want to try one of the icebox melons that is much smaller at 5 to 15 pounds and easier to squeeze into the fridge. And don't forget about those with unique colored rinds and flesh and of course those that lack seeds. For more gardening tips, how-to videos, podcasts and more, visit www.melindamyers.com

Clematis Stem Wilt
Clematis Stem Wilt Your clematis looks beautiful until suddenly the stems and leaves start turning black. Though it looks bad your clematis will survive. The fungus that causes this disease enters your plant through wounds and cracks in the stem near ground level. Fortunately new growth arising below this point will be disease free. Reduce future problems by pruning out and destroying infested stems. Disinfect tools between cuts to reduce the risk of spreading this disease. As new growth emerges from the soil carefully secure it to the support to reduce the risk of cracking and damage. Eliminating the entryways for the fungus will reduce the risk of disease. In the future consider planting the crown of the clematis below the soil surface. This allows the plant to produce new shoots below the point of infection. Try growing small flowered clematis that tend to resist this disease. Alpina, macropetala and the viticella types are a few to consider. A bit more information: For a disease to occur you must have the causal organism (fungus, bacteria, virus) present, disease-promoting weather and susceptible plants. Remove one of these factors and you eliminate the disease. Keep this in mind when managing clematis stem wilt and other plant diseases in your garden.

Watch for and Prevent Borers on Trees and Shrubs
Extreme heat and cold, droughts and floods can leave our plants stressed and more susceptible to damaging borers. These insects are the immature stage of moths and beetles that feed under the bark and inside the stems of plants. Their feeding weakens and in some cases kills the plant. Many borers are opportunists, attacking already stressed trees. We can't control the weather but we can help reduce stress on our plants. Start by growing plants suited to the climate and growing conditions in your landscape. Mulch the area under and around the base of trees and shrubs. Organic mulches like wood chips keep the roots cool and moist and reduce competition from grass and weeds. Be sure to water new plantings thoroughly and as needed the first few years. And do the same for established trees and shrubs during extended drought. This will keep them healthy and help ward off borers. A bit more information: Incorporate trees and shrubs into perennial planting beds. You will create an attractive garden and better environment for the plants. Plus, planting beds as well as mulching will reduce the need for hand trimming and will keep weed whips and mowers away from the trunks of the trees. And don't pile soil or mulch over the stems of shrubs and the trunks of trees. These practices create entryways for pests and encourage disease problems.

Lawn Revival
If sparse, bare spots or lots of weeds describe your lawn, it is time for a little lawn revival. Start by evaluating the current state of your lawn. If more than 60% is bare or filled with weeds, it is time to start over. Look at this as an opportunity to properly prepare the soil, select a more drought tolerant lawn or convert it into a no mow or low maintenance lawn or planting bed. Overseed thin sparse lawns. Core aerate first or use a slit seeder to insure good seed-to-soil contact. For small bare spots use a lawn patch kit or make your own. Mix a handful of quality grass seed into a bucket of topsoil. Remove any dead grass and roughen the soil surface. Then sprinkle the commercial or homemade lawn patch over the prepared bare spot. Keep the soil moist until the grass seed begins to grow. A bit more information: Larger areas will benefit from the addition of organic matter into the top 6 inches of soil before sowing the grass seed or laying sod. Keep the soil moist until the sod has rooted into the soil below and the grass seed begins to grow. Consider overseeding the lawn to help create a more uniform appearance in the lawn.
