Spring will come…Eventually

Thinking about spring planting blog, Jan 16, 18

It has been quite cold the past few weeks. It is hard to think about spring, but maybe thinking about it will warm us up and bring spring weather back to Nebraska sooner. We can begin to plan our landscapes this time of the year to have a plan in place as soon as planting season begins.

Landscaping seems to never be completely finished. Every year you find new plants you really like and unfortunately it is common to lose a few here and there. When you are thinking about a redesign in your landscape, be careful to avoid causing problems to existing plants you want to keep. A common problem I see is when people add soil around an existing tree to add a decorative block border or a new garden bed or to level off a slope surrounding a tree. People often add soil to roots that have emerged from the soil so that they can continue to mow over the roots. Once a tree is growing in a location, adding soil to the rootzone of the tree can and likely will kill the tree.

Tree roots need to breath just like the rest of the tree does. When you add soil to the existing soil around roots, it will basically suffocate the tree. The majority of tree roots are found in the top 18 inches of soil, they are there so that they still have access to oxygen. If you add more soil to the area around the tree, those roots will now be deeper in the soil profile and unable to get the oxygen they need to survive. The tree won’t die immediately from this addition of soil, but overtime the roots will die.

Also, when thinking about your landscape and what changes you will make to it, think about common problem areas. If you have Lilacs that are severely damaged every year with powdery mildew or roses that constantly have black spot, maybe it is time to rethink those plants. If a plant commonly has disease problems, it may be planted in the wrong location. Plants only grow to the best of their abilities in locations where they are supposed to grow. Hostas that are planted in full sun will develop brown, papery areas on their leaves every summer. In this case, the hosta isn’t planted in the best location and should be transplanted to more shade. This gives you a new area of full sun to plant something different in.

Try to think about all of the problems you have had in your landscape in the past. Sometimes our plants grow too large for the area they are planted in. If the plant needs to be pruned often throughout the year so it doesn’t grow over a sidewalk or window, it might be time for removal and replacement with something smaller. Or if the plant has a seedhead that is troublesome to you in some way, replacement may be a good option. Maybe the plant has a heavy top and weak stem, causing it to flop down in your garden or causing you to pinch it back often when you don’t have the time or ability. If this is the case try replacing it with a more self-reliant plant. Landscapes can become weedy or overgrown if the space is too large to manage in your spare time, keep your landscape at a manageable level for you.

Ice and Snow in the Landscape

2015-02-04 09.33.35

Now that we are through the holidays, there is a little less hustle and bustle going on. It was nice to have been blessed with a white Christmas. Fortunately, the snow wasn’t too deep, but there was plenty that we had to get outside for a little cleanup on the sidewalks and driveways. With all the snow we received over the weekend and plenty more weeks of winter to go, I thought I’d give you all a reminder of how to properly take care of snow to not harm our plants.

Deicers can cause damage to our concrete sidewalks and to our plants growing beside them. Many deicing agents contain salt substances, such as sodium chloride and potassium chloride. Because of the salt content found in these products, it can cause severe damage to our plants, if too much is piled on them too often. Typical plant symptoms of salt damage include desiccation (drying out), stunting, dieback, and leaf margin and tip damage that looks as though the leaves were burned by a chemical.

To avoid damage to the concrete, remove the salt as soon as you can. Deicers are meant to make shoveling easier, not to completely melt away the snow and ice. As soon as the salt melts through the ice and snow enough that it can be removed, go out and shovel it off of the concrete. When removing the snow, do it in a manner that protects the landscape plants growing in the yard. Do not pile the snow onto trees, shrubs, or flower gardens. If it has to be piled onto your landscape, move the salt onto the grass and try to do it in a manner that makes it more uniform on the grass surface. If too much salt continually gets piled up on the grass in one location, the turf can be harmed.

The snow didn’t build up too much on our trees with this past snow storm, but when we get a lot of heavy, wet snow, this can be a concern. Sometimes, ice and snow can build up on the branches of our trees and shrubs and can cause the branches to bend improperly. We saw this problem last January with the ice storm that came through. It is best to let snow and ice melt naturally off of our plants. Snow can be lightly brushed off of branches with a broom, if you desire. Do not try to hit the ice off of the tree branches because this can cause you to break some of the branches, which will be more detrimental to the plant. If there is snow on your tree causing it to bend down, it will reform in the spring once the snow melts off of it.

Finally, watch out for your lawn in the winter months as well. It is best to minimize winter traffic on any turf area and especially when frost is present on green turf. If frost has formed and foot or vehicle traffic occurs, the physical abrasion can damage turfgrass. Winter traffic can cause aesthetic damage, physical abrasion, and/or soil damage depending on the situation. Too much traffic on turfgrass at a time when it cannot recover also leads to winter injury. If you have to walk on the lawn for some reason, such as to take a pet outside, try to use a different path each time.
