Spring Bulbs

Gardening has its good and not-so-good parts. It is a healthy hobby, but intense at times. Whether it is a vegetable, annual, or perennial, nothing is as rewarding as seeing the home landscape in full maturity.  However, it takes a lot of work, trial, and error to achieve results.  One benefit of gardening is it teaches us patience.  Good things come to those who wait.  As we are getting ready to put our gardens to bed for winter, we also need to think of next year at the same time, but we will be rewarded in time.

Think about spring color now, how nice it would be to see bright colors emerging as the rest of the garden still slumbers.  Tulips, hyacinths, daffodils, can greet us warmly, but we have to do the work now.  Spring-flowering bulbs are unparalleled in terms of choices for plant material, kinds of blooms and colors, and a varied bloom time.  There is some time left to do this, and you can find some really good deals at your local garden center now.

Some things to consider...
Site:
Most bulbs need well drained soil.  If the area tends to have standing water after a spring thaw, then look for another location.  It is generally recommended not to plant under trees.  Bulbs require five to six hours of full sun at a minimum, and eight to ten for the best flowers.  Clusters, or larger groupings, have the most eye appeal so make sure you have plenty of room for a big display.  Avoid planting in a lawn or location that might be damaged from lawn care.  Their foliage needs as much sun as possible, so if they are cut down before dieback, it may affect the bulb quality. Spring bulbs do best if they are left in the same location year after year, so pick a site with that in mind.  Preparation is key to success for spring bulbs.  Loosen the soil to a depth of about twelve inches.  Add composted organic material to the top eight inches.  If you haven’t had a soil test done, then choose a low nitrogen formula.  There are many tailored just for spring bulbs.

Selection:
“Bulb” is a general term used to describe a host of plants. True bulbs include tulips, lilies, and daffodils.  Crocus start as corms.  Bearded iris and lily of the valley have tubers, which are thick underground stems.  Whichever you choose, tulips and daffodils have a wide variety of colors, and bloom types. They offer the greatest range of bloom times as well. Crocus give you the earliest color.  Hyacinths have a sweet fragrance outside.  Consider mixing and staggering your plantings to give you continuous color from March through May.  Spring bulbs, with very little care, will come back each year, fuller with better color.

Gardeners Have Mulch To Do In Early Spring

There isn't a lot you can do in a Pennsylvania flower garden on a March day, even if it's sunny and warm. But Robert Berghage, associate professor of horticulture in the College of Agricultural Sciences, recommends spreading mulch to delay plant emergence as long as possible.

"You have to keep the soil temperature as cool as possible to delay spring flowers and perennials. A good layer of loosely packed mulch can insulate against temperature fluctuations. Don't mulch too heavily, because a dense mulch will smother plants. A layer of dry leaves would be ideal."

Berghage explains the loose mulch will protect the tops of emerging shoots from rapid temperature changes that still may occur. "If emergence has started, even temperatures below freezing for an extended period usually will not damage the actual flower stalk, which is deep into the bulb at that point," Berghage says.

Trees and shrubs that have begun flowering will retain some dormancy as long as there are no extended warm periods. If the trees do flower fully too soon, Berghage says it's unlikely the tree will bear fruit later in the season.

"Pollination will be poor or nonexistent in most cases because insects and birds aren't really active yet," Berghage points out. "If a freeze happens, that can prevent fruit as well."

Berghage says plants in protected locations close to buildings, pavement or stone walls -- all of which concentrate heat -- will continue to grow and not much can be done to delay growth.

"Keep track of the plants that have significant vegetative or flower-bud injury," Berghage suggests. "In the summer these injured plants should be watered more so stress on the foliage is reduced and the plant can generate food for the next growing season."

If a bulb plant fails to flower this season, Berghage emphasizes that gardeners should let the plant follow its normal life-cycle. "Often gardeners will mow off the leaves if the plant fails to flower," Berghage says. "If the plant's foliage is not allowed to go through the growing season, the plant will be weakened and might not produce quality flowers next season or ever."

Uninvited Guests: Squirrels

With winter fading away (we hope!) now is a good time to implement some of the squirrel management methods described below so you will be ready for next winter … and deal with any current squirrel issues!

During the cold winter months, wildlife such as tree squirrels sometimes find their way into buildings and homes through loose siding or ventilation screens, looking for a place to nest. Once inside, they can damage walls, insulation, and tendency to chew. In most cases, these squirrels can be managed using IPM tactics that are safe and effective.

Step 1 Pest Identification
The first step in wildlife pest management is identifying what type of squirrel is causing damage to your property. The eastern gray squirrel can range in color from black to silver with a white belly. They are 16 to 24 inches in length. Gray squirrels can be found in any area that has nuts and seeds, including urban backyards. Flying squirrels are smaller than other tree squirrels, between 8 and 10 inches in length. They vary in color from gray to brown, and have broad webs of skin connecting the fore and hind legs at the wrists and a flattened tail that allows them to glide from tree to tree. Squirrels can be found anywhere there is an ample supply of nuts and seeds.

Step 2 Prevention
There are many ways to prevent squirrel damage:

• Make your property less hospitable to wildlife pests by keeping the property clean and maintained.
• Trim trees and limbs to 6 to 8 feet away from buildings to prevent squirrels from jumping onto roofs.
• Exclude squirrels from inside buildings by using caulking or mesh to seal up holes where small animals could gain entry.
• Install fences around plants, trees and gardens to reduce their source of food.
  Place birdfeeders 15 to 30 feet from buildings.
• Consider removing birdfeeders if squirrels are a problem.
  

Step 3 Controlling Squirrels Safely
There are very few repellants currently available for use on squirrels and have a very limited success rate. In addition, there are no fumigants or toxicants federally registered for use on squirrels. Try these IPM methods instead:

• Frightening – Frighten squirrels by using loud noises or lights in attics or closets where they are nesting.
• Trapping – Use wire-cage and box traps to capture squirrels alive, baiting the traps with orange or apple slices, walnuts and pecans removed from the shell, or peanut butter. Check the traps twice a day and release the squirrel once exclusion tactics are used to secure the building.

Pruning Peach Trees

The best time to prune peach trees is the middle of April. Pruning earlier, before bud swell, makes the tree susceptible to damage from the disease cystospora canker. A pruned peach tree is less susceptible to the disease brown rot. Brown rot is that brown fuzzy disease that grows on peach fruit as it ripens.

A peach tree should have 3 or 4 main limbs called scaffolds. The tree should have a bowl shaped appearance when pruning is complete. Prune annually to ensure uniform growth and fruit production. Always use sharp, clean pruners.

First, remove broken or diseased branches. Second, cut out vigorous upright shoots that developed on the inside of the main limbs. This is referred to as open center pruning. Finally, once the 3 or 4 main scaffolds have developed, allow secondary branches to develop off of the main scaffolds. Secondary branches should be spaced about 8” apart. Continue to keep upright shoots from developing on the inside of the scaffold limbs. As the tree matures, head back or cut off the ends of secondary branches to a side shoot so new fruiting wood is encouraged to develop. Remove all pruned wood and decayed fruit from around the tree.

Save Your Trees, Your Back and Your Wallet From Mulch Volcanoes!

Spring time is right around the corner so it must be time to start piling on the mulch around our trees … right? Wrong! Mounds of mulch around the trunk encourages rodents and diseases and inhibits oxygen from getting down to the roots (yes, roots need to breathe too!). Now don’t get me wrong, mulch is part of good tree management; just not heaps of mulch. But, you say, professional landscapers do it so it must be beneficial! Sorry, not true. And if your landscaper suggests otherwise, you may want to suggest that they brush up on the topic (show them the website below!) rather than charging you for time and materials to make “mulch volcanoes” that can only harm your trees, not help them.

Tree trunks are meant to be above ground and open to the air, right down to where the trunk flares out at the soil line. What flare, you ask? Well, the root flare is the zone where the tree trunk turns into the root system and the flare should be right at the soil line. If your tree trunk at ground level looks as straight as a telephone pole then the tree is planted too deep. But that’s for another article. Now back to mulching trees.

Proper mulching is good for trees. So, how do we mulch trees properly?

• Keep mulch at least 3-4 inches away from the tree trunk.
• Mulch out to the "drip line" of the tree. The tree (and the grass that you eliminate) will thank you. Must have lawn under your tree? Make the mulched area as large as you can.
• Layer fine-textured mulch no more than 2 inches deep and coarse-textured mulch no more than 4 inches deep.
• Occasionally fluff the mulch layer, especially before putting on new mulch. Remember that the entire mulch layer (old plus new) should be only 2 to 4 inches deep.
