|Due to the nature of air spading work, we had to perform this portion of the job at night. Typically, soil is aerated using a tiller, but aerating near existing plant roots with a tiller could potentially destroy the root system. Air spading (pictured right and above) allows us to aerate the soil around trees without damaging the roots. The air spade we fabricated and used for this project is attached to a large air compressor and efficiently loosens the soil by forcing a targeted stream of air to an area so that we are able to install plants. Pictured below is a specimen japanese maple that required using an all-terrain lift to access the 12′ raised planter it was going in.
