A few weeks ago, I got to go out to Oregon and visit several nurseries to see their selection. It was very cool to see the variety of plants that they can grow that we can’t. Geographically, we’re almost straight across the country from each other with our southern borders hovering around the 41-42° North parallel line. We are zone 5 and they are zone 8 or 9 depending on where along the coast you are. It was amazing to hear that they can potentially gain up to 12” on a Japanese maple in one growing season or to see 4.5’ emerald green arbs that they say in a few weeks will be nice 5-6’ arbs. It was a very busy trip as I saw 10 different nurseries in 4 days, but it was totally worth it.

A Boxwood Revolution! 

Have you heard about the two NewGen® boxwood that have come onto the market? 'Independence' and 'Freedom' came out recently and are a fresh breeze of improved genetics in the Buxus arena. They have a strong tolerance to boxwood blight and are resistant to leaf miner. Both are considered zone 5-8.

With both of these being relatively new to the market finding any that are larger than a #3 is difficult. But with more time and a few more growing seasons, I am sure we will start seeing larger plants available. At this time, we do not stock any of these at Christensen’s Plant Center but can special order them for you. I am looking at bringing some in for next spring and just wanted to make you aware of these new beautiful boxwood that are coming soon.

Whether you are going to sod or to seed your next lawn project there are advantages to both. Depending on the job, leveraging your options could give you a competitive advantage with your customers. Here are how the choices stack up.

The biggest advantage that sod has is the instant gratification of a green lawn and immediate erosion control by acting as a blanket to help hold soil in place. Sod has a faster turnaround time for when your customer can use their yard. After about two to three weeks the sod is rooted in and ready for normal lawn traffic. So, for those customers that decided to re-do the whole yard right before the graduation party/outdoor wedding/backyard baby shower, think sod.

The biggest advantage when you choose seed is the initial cost. Both the cost of product and installation start out lower. Having many different choices of blends of seed to make sure that you get the right lawn you are looking for. From Kentucky bluegrass to perennial ryegrass to red fescue, seed allows you to customize your mix to the area you’re planting. Seed can be a boon when you’re working with a discerning homeowner that’s willing to wait a little to get exactly what they want out of their lawn.

Whether you choose to seed or sod, here at Christensen’s we have options for both to make sure you get the right product for your job. When it comes to seed Christensen’s carries three choices for you, sunny mix, shady mix, and fast green mix. If you require a special mix for your job beyond those, we can special order it for you. For those spots that need a little extra care, you can pick up sunny/shady lawn patch.

We also offer several items to make sure that your seed is given the best possible start. Try PennMulch, a mixture that fertilizes, holds in moisture, and holds the seed in place, over top of your seed to speed up germination and fill in quickly. Straw blankets are MDOT approved and help manage erosion, protect seeds from birds and shade the ground to help retain moisture. Talk to a sales rep about EZ Straw, fertilizer, sprinkler towers, and hoses. We stock all of these items to make your lawn and turf endeavors successful.

If sod is your choice, Christensen’s stocks a few pallets of fresh-cut sod in our yard, brought in bi-weekly. However, if you let us know when you are going to be laying the sod we can get as much as you need for your job. Upon ordering, you can pick it up from our yard or, if it meets the quantity minimum, you can have it shipped directly to your job site or yard.

So, whether you are laying sod or spreading seed Christensen’s has you covered.

Ever wonder how Christensen’s stores and maintains trees in "the field" to keep them viable all year long? If you've ever tried to keep above-ground material healthy over a long period of time you know there are challenges to be met. But for the most part, it’s really not that far off from what you do when you plant a tree in a landscape - except we do it for a few thousand trees.

First, we grade out the area where the trees are going to go and then auger holes to place the trees in. After the tree is straight in the hole we backfill it with dirt and lightly pack it down.

Then an irrigation emitter is placed into every root ball. We use two different sizes of irrigation emitters, yellow for trees that are 3” or smaller and black for anything larger. We do an irrigation check on the trees at least once a week depending on the time of year. The irrigation system for the field might run 24 hours a day in the summer, so making sure that the trees get the required amount of water is sometimes difficult. We check the emitters to make sure they are not clogged, that they are spraying correctly, and that they haven’t come off of the feeder line and are flooding the tree.

After the trees are put in the ground we apply pre-emergent to prevent weeds from growing in the root balls and the surrounding soil. We generally do this twice a year. As the year goes on if weeds begin to grow we spray with non-selective herbicide. We add a non-toxic blue indicator dye to make sure that we are only hitting the targeted weeds and not the trees.

We do several other sprays throughout the year to prevent disease or insect damage. For instance, we spray for apple scab in the early spring as the trees just start to leaf out. There's also a scheduled spray to prevent gypsy moth, when the temperature is right. We do other targeted sprays as issues come up. Our nursery is inspected regularly for pests so we can be sure that our material is ready for distribution.

At the end of the season we put tree guards on the trunks to prevent damage that could be caused by roaming rabbits and deer. In the spring we remove any guards that are made from solid material in order to allow the trunk of the tree to stay dry and also to prevent bugs from making a home there.

Lastly, when we lift trees from the field to go on your truck, we carefully re-wrap the rootball with fresh burlap if needed. You can be confident that the trees we store are ready to go on your landscape job, spring, summer, or fall.

Boxwood blight is a fungal disease of boxwood that results in the defoliation and decline of boxwood plants. Once it’s in the landscape it is very costly and difficult to control with fungicides. The boxwood blight fungus has a short life cycle and infections can spread quickly between plants, especially under humid, warm and wet conditions that favor disease development.

The main way that this disease is spread is through the movement of infected plants, cuttings, and boxwood debris. The sticky fungus spores are also spread on contaminated tools and equipment, worker's clothes, and water. The spores are unlikely to travel long distances through the wind. All plants infected with the fungus should be destroyed, as the chance of further spreading the fungus is highly probable. Limiting the spread of this sticky fungus is very difficult and can only be accomplished by following good sanitation practices.

Boxwood blight has been found in Michigan. Because of this we will NOT accept any returns on boxwood once they have left the nursery. We will also ask that you do not bring any boxwood plants, leaf litter, or clippings into our nursery. We reserve the right to not load any vehicle that has boxwood or debris from outside of our nursery. Please do not bring in any samples of boxwood that you are trying to match - take several pictures of the plant you are trying to match and we will help the best we can.

Boxwood blight can look like many other issues that boxwood can have, such as leaf spot, winter burn, and other non-threatening fungal diseases. This means that:

The only way to confirm whether a plant has boxwood blight is to submit samples to a professional plant disease diagnostic lab.
