Due to the flat square structure of the “roof”, roof top trees typically look at their best from an architectural point of view when planted in lines or squares. This being the case it is important to make sure the stems line up, the heads are at a similar height and they are square. We sell roof / umbrella / parasol trees UK wide, we also provide a planting service. Machinery is required to plant all but the very smallest of the trees we supply so taking time to plan will save time and money in the long run.
Parasol Tree Care and Maintenance
Maintaining parasol trees is relatively straight forward. All you need is a sturdy platform with the necessary support, a sharp pair of secateurs, loppers, safety glasses and appropriate gloves which are available from Felco, our preferred brand. The aim is to clip lightly once or twice during the growing season to retain the shape of the crown and a sense of order. Once a season – timing dependent on species, the aim is to prune back the previous year’s growth, leaving the original leaders in place. Over time these leaders can be left to grow to the desired length. Once the canopy is the correct size it can be maintained as such by clipping back each season – easy!
Some species such as Limes, Mulberries and Planes for example enjoy being managed heavily where only the main leaders remain at the end of each season. Carpinus Betulus or Hornbeam on the other hand, look better left with a dense network of branches. The species of parasol tree you choose will determine the pruning method.
Feeding & Watering
We supply detailed feed and watering instructions with all orders. While failures are rare, they tend to be down to a lack of water and in very rare cases to much water. It is therefore important to implement a strict watering regime once the trees are planted and to monitor soil conditions closely. Plants will benefit from a seasonal feed and therefore application of organic or manufactured feed. General purpose granular fertilisers such as Osmocoat are good for this purpose.
Roof top trees are particularly popular on the continent and this seems to be rubbing off on home-owners back home. In Zurich Switzerland for example umbrella or parasol trees can be regularly found at tram stations around lake Zurich (Zürichsee), offering passengers welcomed shade in the summer months. All along the south coast of France, they can be found at private residences overlooking the Mediterranean. Plane trees (that don’t normally enjoy sea side locations) have been planted in small private harbours meters from the sea and they are thriving.
Roof form trees or parasol trees are extremely versatile and while still not as common in the UK as on the continent, they are catching on. From young trees to the largest mature trees available in Europe we will help you find the trees that best suit your plans. Please contact us for more details.
