Many of our favorite plants have multiple personalities. There is a good side and a bad side, shown especially when they escape the landscape and spread to our native areas, becoming invasive. When it comes to invasive plants in landscapes, there is good news and bad news. The bad news is that invasive plants are planted intentionally as ornamentals, and several species known to be invasive are readily available for sale from nurseries and garden centers. The good news is that there are many beautiful plants to choose from that are not invasive. Indeed, while many of the most picturesque garden plants are not native to the Midwest, the majority are not invasive. For example, hosta, smoke tree, boxwoods, Japanese tree lilacs, and dwarf shrub junipers are all non-native to the region but are not known to be invasive. However, brad ford pear, red barberry, burning bush and other “go-to” landscape plants are damaging our natural ecosystem by establishing themselves where they really aren’t welcome. These plants should be avoided and even considered for removal and replacement.

Garlic mustard produces chemicals that inhibit the growth of other plants.

Several professional landscape and nursery organizations have taken the charge in eliminating these harmful plants. They believe invasive species adversely affect the integrity of ecosystems and cause both environmental degradation and economic harm. Invasive species – whether they are plants, animals, fungi, or insects – may cause deterioration of native habitats and plant communities as well as damage to designed and managed ecosystems. Because invasives reduce biodiversity and disrupt the healthy structure and function of both native and human ecosystems, planners, contractors, arborists, landscape architects and other green industry professionals should not introduce or support the use of known invasive species. And, where they are already existing, steps should be taken to eradicate them.

Iron_Clorosis_of_TreesMany trees, shrubs, and other ornamental plantings in Indiana and throughout the Midwest suffer from iron deficiency caused by high pH (alkaline) soil. Soil pH affects plant growth directly and indirectly by affecting the availability of essential nutrients and microbial activity. One of these nutrients is iron, an essential plant nutrient that is required for the production of chlorophyll. Chlorophyll is necessary for photosynthesis and gives plants their green color. Iron (and manganese) deficiency results in leaf yellowing (chlorosis); over time, scorching of foliage, dieback and even death of the tree or shrub can result.

Iron Chlorosis of Trees and Shrubs talks about the symptoms, the cause and the managing of iron chlorosis. One of the authors is Lindsey Purcell, an urban forestry specialist from the Department of Forestry and Natural Resources at Purdue University.

Purdue Landscape Report: We all have heard about dormancy and the restful time of woody plants in our landscapes. That “chill-out” time is nearing the end and it’s time to think about tree maintenance. Trees and shrubs have actually been growing for quite some time, we just can’t see it… yet. Woody plants begin growth after the chilling requirements have been filled. These requirements are different for every plant. Chilling units are hours of time spent above freezing. The number of hours required for chilling varies for different plants from less than 500 to 1,500 hours or more. Many people think the plant is tracking hours below freezing, but in actuality, hours below freezing has no effect on chilling but does increase cold hardiness. Our mild winter and early spring arrival is playing a role in this process.

Spring-Buds

Figure 1. These oak tree buds may look dormant but have completed their chilling requirement and are ready to break. Source

An important maintenance task is supplemental fertilization during early spring weather, especially if there wasn’t any type of fall fertilization. Let’s take a look at how a tree uses and gains energy during the year to understand why and when trees need good nutrition. After the leaves have fallen there is no way to generate food because without leaves, there is no photosynthesis. There are huge demands on the carbohydrate reserves due to increased metabolic functions to support new leaves, flowers and fruit. Supplemental nutrition can help if storage levels are low or depleted until the new photosynthates are available. That’s a huge demand on its reserves! The tree must rely on stored carbohydrate reserves in its woody parts such as stems and branches to grow. Hopefully, the tree was healthy and developing those reserves going into fall or supplemental nutrition was offered with fall fertilization. If not, then the tree exhausts much of its energy and is in need of new resources.  In some situations, it may be considered safer for the tree to apply fertilizer in the spring. Fall applications, if applied too early in the fall season, can create the risk of forcing the plant into becoming metabolically active right when cold weather hits, creating growth susceptible to freeze damage.

Many woody plants begin the new year’s growth with stored food from the year before. An application of fertilizer in the spring gives an additional boost to this new growth. It is important to note that not all trees and shrubs need fertilization, however, most can benefit from this application, especially the younger actively growing trees. In forests, soils have an abundance of nutrients, but in our landscapes and urban forest areas, that’s not often the case.  As we sweep away leaves, twigs and fallen bark, we’re removing potential recycling of nutrients for the soil. Additionally, the grass around our trees is unnatural and often outcompetes trees for available nutrients and water. That’s why we need to fertilize our trees, spring or fall. Look for signs that your tree is lacking nutrients in the soil. If you see these signs, fertilization may be necessary.

Seasonal-Starch

Figure 2. The graph shows the starch loss or energy used during various growing stages for the tree during the year. Most energy is depleted after leaf emergence and then regained as leaves begin photosynthesizing new resources. Source

  • Shorter than normal annual twig growth
  • Undersized leaves that are fewer in number
  • Dead branches and branch tips
  • Leaf veins darker than leaf margins
  • Leaves any other color than dark green, such as yellow or red

However, never fertilize without getting a soil test. If your trees are experiencing any of the above symptoms, have your local arborist inspect the tree to determine the best treatment. Also, Review Consumer Horticulture: Fertilizing Woody Plants (pdf) for more details on fertilizer application techniques and rates.

Now for just a little about tree pruning. All of that new tree growth is going to prompt the pruning activities… be patient!  Once trees start budding and blooming in the spring hold off until after the flush.  Pruning in the spring can limit bloom potential and remove newly expanding leaves that will be needed to produce new food products for energy.

Generally, the best time to prune is several weeks after the spring flush or during the summer months. Early spring pruning should focus primarily on pruning for safety to remove any dead, dying or decayed branches. Aesthetic or structural pruning can be completed much later and when the tree is better prepared to seal those pruning wounds with energy reserves.  For more information refer to the publication Tree Pruning Essentials from the Education Store on pruning topics.

Purdue Landscape Report: Yes, we need trees and here’s why…

Trees have presented as more than just a pretty face as research has indicated that trees are even more valuable for their function as much as their form. Currently, more than 50 percent of the world’s population now lives in towns and cities. In the Hoosier state, the last census indicated that 72% of our population lives in an urban area and this statistic is increasing annually.

For the most part, the rapid expansion of cities takes place with little consideration to land use planning strategy. The resulting human pressure has highly damaging effects on our urban trees and green spaces. The environmental impacts of climate change are intensified by urbanization such as increased pollution, increased temperatures, and larger demands on infrastructure such as stormwater systems.

Urban trees can help to mitigate some of the negative impacts and social consequences of urban sprawl and make cities more resilient to these changes. These important functions are called ecosystem services. This is the way urban foresters measure the benefits that trees provide other than just their beauty. Ecosystems services are the many benefits that trees and plants provide to the community. They improve our quality of life by providing food, cleaner air and water, regulating temperatures, supporting pollination and providing recreational, health and spiritual benefits.

Here are some easy ways in which urban trees and woodlots contribute to making cities more environmentally sustainable and livable:

  • Trees can contribute to the increase of local food and nutrition security, providing food such as fruits and nuts for wildlife and human consumption.
  • Trees play an important role in increasing urban biodiversity, providing plants and animals with a proper habitat, food and protection.
  • A mature tree can absorb up to 350 lbs. of CO2 per year. As a result, trees play an important role in climate change mitigation. In cities with high levels of pollution, trees can improve air quality making cities healthier places to live in.
  • Strategic placement of trees in cities can help to cool the air between 30-40o F, thus reducing the urban “heat island” effect, helping reduce extreme heat conditions in summer weather.
  • Large trees are great biological filters for urban pollutants and particulate pollution. They absorb pollutant gases (such as carbon monoxide, nitrogen oxides, ozone and Sulphur oxides) and filter fine particulates such as dust, dirt, or smoke out of the air by trapping them on leaves and bark.
  • Research shows that living in close proximity of urban green spaces and having access to them, can improve physical and mental health, for example by decreasing high blood pressure and stress. Also, research indicates greatly improved neo-natal health as well. This, in turn, contributes to the well-being of urban communities.
  • Mature trees regulate water flow and play a key role in preventing floods and reducing the risk of sewer overflow. Stormwater management is a crucial city infrastructure issue and trees help. A mature tree, for instance, can intercept more than 5,000 gallons of water per year and without trees, every rain would contribute floods.
  • Trees also help to reduce carbon emissions by helping to conserve energy. For example, the correct placement of trees around buildings can reduce the need for air conditioning by 30 percent and reduce winter heating bills by 20-50 percent.
  • Planning urban landscapes with trees can increase property value, by up to 15 percent, and attract tourism and business.

These are just a few examples of the functional benefits that trees provide to our everyday life. A community or neighborhood with well-planned and well-managed green infrastructure becomes more resilient, sustainable and equitable in terms of livelihood improvement, climate change mitigation and adaptation, disaster risk reduction and ecosystems conservation. Throughout their lifetime, trees can thus provide a benefit package worth two to three times more than the investment made in planting and caring for them. Trees aren’t the answer, but they are part of the equation. Planting trees is important, but their maintenance is as equally important.

Trees make life better.

Rainscaping, planting to help with water runoff.

The Purdue Extension and Illinois-Indiana Sea Grant Rainscaping Education Program was highlighted in the National Oceanic and Atmospheric Administration’s Education Accomplishments Report for fiscal year 2019.

This report highlighted all of NOAA’s greatest accomplishments related to education in five main goal areas: science informed society, conservation and stewardship, safety and preparedness, future workforce and organizational excellence.

The Rainscaping Education Program was featured in the Conservation and Stewardship section of the report. The Purdue Rainscaping Education Program offers state-wide training for Purdue Master Gardeners, conservation agencies and organizations, stormwater professionals and landscape companies and consultants. Through two-day workshop sessions, the program provides an introduction to rainscaping and rain gardens, including segments on site selection, plant selection, garden design, installation, maintenance and community engagement.

“It is wonderful to have the innovative and collaborative work of the Purdue Rainscaping Education Team recognized for its efforts,” Kara Salazar, assistant program leader and extension specialist for sustainable communities said. “The team has been working together since 2013 to develop and implement the interdisciplinary program addressing the need for community education on sustainable landscape practices to prevent polluted runoff.”

Salazar and John Orick, Purdue Master Gardener State Coordinator, are co-leads on the project. View  the full Rainscaping Team.
