Landscapes New & Old – Maintenance & Care

Your landscapes will always require some form of care, there is no such thing as a care free landscape. A landscape will require frequent weeding, trimming, and the occasional dividing of your perennials and ornamental grasses, to maintain the original design intent of the landscape.

When a landscape is originally installed, thoughts towards what plants will go in will determine what level of care the landscape will require. Hedges will require regular pruning or the hedges will become unruly and can overtake the surrounding plants. Plant selection can help reduce pruning frequencies for example; if you are looking for a small evergreen hedge that you wish to stay small, you want to choose a plant that will not mature to a large size. This will reduce pruning frequencies. This same practice can also be applied to flowering shrubs. The industry as of late has started to develop plants that have a much smaller mature size such as Little Lime Hydrangea. These smaller mature sizes can reduce pruning times and are great for smaller spaces that cannot contain its larger counter- part; Limelight Hydrangea.

The same thought in pruning goes for well-established landscapes. Older landscapes unfortunately do not have that luxury, but the use of chemical growth inhibitors can be implemented to reduce level of pruning.

Weeding is universal in all landscapes, if weeding is not done nature will reclaim it; extreme vigilance is necessary when the wind, birds or other animals deposit weed seeds within your landscape. There are many methods used to try and reduce weeding such as Preen, which only prevents weed seeds from germinating, it does not stop weeds that already exist, which is a common misconception. Another issue that most people do not know is that Preen can also inhibit your groundcover from spreading. A second chemical application used is Round Up, this chemical is a non-selective herbicide that will kill almost everything that it comes into contact with. Yes, there are plants out there that can understand such an assault, so even Round Up is not the complete answer. Round Up is a great product, and when used as directed it can be a great tool to help reduce weeds within the landscape. A physical barrier is also frequently used, which is great if you are trying to smother existing weeds that are a nuisance, but the usefulness ends there. What most people do not understand is that organic matter will end up on top of the barrier. Whether you use mulch (which will break down to become soil) or any other type of organic material, soil will eventually end up there via wind, birds etc. The best way to combat weeds is to plant a landscape that can help smother the ground reducing that competition. Plants such as Hostas and other ground coverings cover the ground, reducing the spaces in which weeds can grow. Planting such plants, again, is not a guarantee that weeds will not grow. They need to become established first, maintaining a weed free zone until that time. Once these plants have become established your weeding frequencies will be greatly reduced.

Another great way to help reduce weeds within your planting space is to provide a 3” layer of mulch that has a great matting capacity, this means the fibers fuse together. This matted layer not only provides a great level of water retention for the soil, but creates a thermal barrier that helps prevent weed seeds from growing. Again this is not a guarantee that weeds will not grow, sometimes just physically removing them is the best option.

Winter preparation can be an intricate part of your landscape maintenance. Being prepared can be a difficult thing to adjust for, one cannot know what kind of winter we are going to have. Your best way to assure that most of your plants will make it through the winter is to make sure you select plant material that grows well within our growing zone. Zones are based on low temperatures throughout our county. Choosing plant material that is on the boarder of the zones can leave you a little heartbroken if the winter’s low temperatures dip too much lower than those plants tolerances. Winters with a great deal of snow can be very good to retain soil temperature by creating an insulating layer, while winters with little snow and a great deal of cold can wreak havoc on all of your landscape plants. Broad leaf evergreens are extremely susceptible to winter desiccation. This is when a plant tries to draw moisture from the frozen earth and there is nothing to draw from or when there are high winds that pull the moisture right from the leaves causing the plants leaves to fold in and turn brown. How to prevent this is to either physically adding something around the plant to help protect the plant from the damaging winds and to shade the plant when there is a great deal of sun during those late Indian Summers that we are known for. Another option to help reduce this is to add a chemical application called an anti-desiccant which will help close the plants pores and help prevent water loss. Perennials can also be susceptible to harsh winter weather that can not only cause them to be stunted for the season but also can cause them to parish. To assist this adding mulch to help insulate the soil is a great deal of help and if you have a particular sensitive perennial that you are growing that is on the boarder of our growing zone you can place straw on top of them to help keep them for the winter. A winter like the one that we have just had is something that no one can prepare for, no matter how far within the tolerances you are with your plant material, temperatures fell far below what we have seen in many decades so remember mother nature can be very unpredictable and we must be prepared for almost anything.

Once your landscape has become established, your bed maintenance should be greatly reduced, granted that you do not have a hedge filled formal garden. The general removal of the occasional weed, along with seasonal pruning and the occasional dividing of perennials and ornamental grasses should be all that is needed to maintain a healthy and well-kept landscape. Keep following our future blogs on tips on transplanting and dividing.
