• Cultivar grows extremely quickly. These trees will often reach 18-20' within two years of planting.
• Structural integrity to reach a mature height of 40 - 50 feet. Average height is 45' and width is 15-20'. 
• Width can easily be controlled by pruning. 
• Grows well in all climates. This tree is hardy down to the cold of zones 2/3, up to zones 9/10.
• Disease resistant and has no known insect problems that affect the overall growth habit.
• Grows well in many different soil types, from sandy to clay soils. 
• Moisture is an important requirement for Hybrid SuperTrees. If water is provided weekly during the first year after planting, the root system will easily support the tree after that, unless extreme drought conditions occur.

HOW FAR APART TO PLANT - will vary of course, but a six foot spacing works well if you are planting a single row. It is ideal to plant two rows and then stretch to eight foot spacing between the trees and also eight feet between the two rows, but stager the trees between the two rows. This gives a very effective wind, snow, dust, sound and visual barrier. The row of trees will be thick enough that it is difficult to walk through them after three years of growth. 

A WORD OF CAUTION: Please do not trust other internet sellers who claim these trees will live longer than 30 years or even "up to 70 years."  It is simply not true. We believe in being honest with our customers! Our experience indicates that Hybrid SuperTrees will begin to have broken branches and decline at about 18-20 years old. Total lifespan seems to be about 30 years. We have about 500 of these Hybrid SuperTrees at our nursery that are 30 years old, which we are about to remove to replant more. Average trunk diameter of those specimens is about 30". They look pretty rough by 30 years old, so plan to remove them before they begin to rapidly decline and drop branches.

ANOTHER WORD OF CAUTION: Avoid purchasing this species of tree from nurseries or online sellers who ship them as simple cuttings or scions. This particular species struggles to establish without a healthy complete root system. The death loss percentage can be very high (35%+) because this hybrid species DOES NOT like to start with weak roots or with no established roots, and is sensitive to drying out and can be hard to get established. This means extra work for you, even if the seller agrees to replace your dead trees. If one tree in a row dies, you will have an open space in the row that is difficult to fill. The new replacements will be very small and the visual contrast will be exaggerated because the first set of trees planted will grow so quickly. Of course, you will unfortunately experience the same death loss percentage (35%+) with your replacements. Also, be aware that unrooted stock can only be planted in early spring. We do offer bare-root transplant stock, but all of ours are second or third year plants with well established root systems. We are also the only nursery in the US with the ability to ship plugs to fill in any gaps from March to October, if you did need a replacement tree. 

OUR BARE ROOT STOCK IS EXCELLENT:  Our bare root transplants are shipped dormant and the roots are well wrapped in moist dunnage for the trip. Our stock WILL NOT die if given even basic care, and you can plant anytime during spring. Your trees can be kept in water for a day or two if you cannot plant immediately after they arrive. It is very important that you keep the bare root stock moist at all times. Stock will arrive in a long carton, via either UPS, Postal or SpeeDee Delivery, depending on where you live. Shipping cost varies by location and quantity ordered, which determines the weight. We do not try to profit on shipping, it is already too expensive in our opinion. Instructions for care and planting will be shipped in the box with your trees. Please read those instructions. You can also read information about Care and Planting instructions here.

OUR ROOTED-PLUG METHOD IS SUPERIOR: Our Karsten Nursery Hybrid SuperTrees are sold and shipped as rooted plugs, with soil enclosing the roots so they are never exposed to the air. Our bare root transplants are shipped dormant and the roots are well wrapped in moist dunnage for the trip. Our stock WILL NOT die if given even basic care, and you can plant anytime during the year. Your trees can be kept in water for a week or two if you cannot plant immediately after they arrive. It is very important that you DO NOT remove the netting on the plugs, which will be around the root ball. The root plug is about the size of a soda can so it's easy to plant. Your plug trees will arrive as 12-24" rooted plugs in a long carton, via either UPS, Postal or SpeeDee Delivery, depending on where you live. Shipping cost varies by location and quantity ordered, which determines the weight. We do not try to profit on shipping, it is already too expensive in our opinion. Instructions for care and planting will be shipped in the box with your trees. Please read those instructions. You can also read information about care & planting on this page.

ADD SOME PLANTSKYDD® TO YOUR ORDER! We highly recommend that you also purchase some PlantSkydd® animal repellent to protect your young trees from hungry critters like rabbits & deer. We are an authorized provider of PlantSkydd® & offer it because we want our trees to arrive healthy & then enjoy the best possible conditions to thrive after you planet them. You can order your PlantSkydd® in liquid or powder concentrate form, along with a sprayer to apply it to your freshly planted trees. Click here to see your options.

WHY PLANT HYBRID SUPERTREES? Other trees can take 30 years to give you shade and provide a visual barrier from unsightly views. Why wait that long? If you need a fast-growing hedge row that will provide quick protection from wind, snow, noise or dust, order your Hybrid SuperTrees from Karsten Nursery and get them in the ground soon! If you have enough space, we encourage you to plant a variety of other species parallel to your row of Hybrids so that in 20 years you will have a healthy, mature stand of trees inside the declining row of Willows.
