Planting Ginkgo biloba Goldspire™ Obelisk Trees
Adding just one type of tree, bush, or plant can totally transform a space.
I enjoy planting interesting and beautiful specimens that add texture and beauty at different times throughout the year. I also like arranging groups of certain plantings to create borders, allées and appealing displays. Last week, I purchased six Ginkgo biloba Goldspire™ Obelisk trees from Select Horticulture Inc. in nearby Pound Ridge, New York. I knew these narrow upright tower trees would look excellent on both sides of my pool. They were delivered, positioned, and planted right away - and they look just perfect.
Here are some photos, enjoy.
-
- There is always so much happening at my Bedford, New York farm. On this day, six Ginkgo biloba Goldspire™ Obelisk trees arrived. Select Horticulture Inc. secures their trees excellently for transport – they came in perfect condition.
-
- Ginkgo Goldspire™ is a highly ornamental, non-fruiting male tree originating in Italy. It has a very upright, tight fastigiate habit, and the foliage tends to be smaller than other species.
-
- Once the trees are delivered, each one is positioned inside the pool area. Each grows about one to two feet per year and prefers mostly sun and well-drained soil.
-
- New foliage on the Ginkgo Goldspire™ emerges a rich shade of green, fan-shaped, and slightly curled. It keeps its color through summer, then turns buttery shades of yellow and gold in autumn before dropping.
-
- I placed wooden stakes where I wanted the trees to go.
-
- My outdoor grounds crew foreman, Chhiring Sherpa, measures the locations and then uses white landscape paint to mark a circle where each tree will be planted. These specimens should have at least 10-feet of space between them.
-
- Chhiring goes over the circle line with our Classen Pro HSC18 sod cutter. The sod cutter goes over the lines smoothly and deeply.
-
- There are different types of sod cutters, but they all essentially cut grass at the roots so entire sections of sod can be removed to expose the bare ground underneath.
-
- Here is the new cleared out area. This will become the tree pit.
-
- All six circles are done in the same way. It’s important to get these trees into the ground before the grass underneath the waiting trees gets burned – it’s been unseasonably warm this week.
-
- The team begins digging. The holes must be pretty wide – each one should be at least two to five times as wide as the root ball, but no deeper than the root ball. Once in the hole, the top of the root ball should just be slightly higher than the soil surface. The hole sides should also be slanted. Digging a proper hole helps to provide the best opportunity for roots to expand into its new growing environment.
-
- A good fertilizer made especially for new transplanted specimens should always be used. This is Miracle-Gro Shake ‘N Feed Flowering Trees and Shrubs Plant Food. A generous amount of the fertilizer is mixed in with the nutrient-rich soil.
-
- Then each tree is placed into its designated hole. When moving heavy specimens, only hold it by the root ball, the base and trunk of the planting – never by its branches, which could easily break. Once the Ginkgo is in its hole it is turned so it is straight and its best side is facing the pool.
-
- This part of the process is very important. Chhiring stands at a distance to make sure the tree is positioned properly. Always look at the specimen from all sides, especially from where it will be seen most often. And because these trees are specially shaped with straight sides, they must all be turned just right, so the sides match.
-
- All the trees are positioned first before any backfilling is done, so adjustments can be made. These trees are now all in the ground and positioned correctly.
-
- The burlap and metal cage wrappings help to support the root ball during loading, shipping, and transplanting. Some leave them in the ground, but I prefer to remove everything completely, so there is nothing blocking the growing roots.
-
- Finally, the crew backfills the holes until they are properly filled. And remember, don’t plant it too deeply – always leave it “bare to the flare.”
-
- Phurba tidies up the tree pit and makes sure there is good contact between the tree and the surrounding soil.
-
- Here are three of the Ginkgo Goldspire™ Obelisk trees on one side. The term “obelisk” refers to the tall, four-sided, narrow tapering which ends in a pyramid shape at the top.
-
- And here is a view looking south. The trees look so beautiful with the staddle stones at one end. I am looking forward to seeing these Ginkgo biloba Goldspire™ Obelisk trees develop and flourish.
