Fertilising a Taxus baccata 'Fastigiata Robusta'
To support the robust and dense growth of Taxus 'Fastigiata Robusta', a conscientious fertilization routine is crucial. It is recommended to fertilize this evergreen hedge plant in early spring, just before the onset of the growth season. Utilize a balanced, slow-release fertilizer that is appropriate for evergreen species, ensuring it provides a steady supply of nutrients over several months.
The application of fertilizer should be calibrated to the plant's specific needs, taking into account its moderate growth rate of 10-20 cm per year and its ability to thrive in a range of soil types, provided they are well-drained. A single annual feeding is typically sufficient to maintain the plant's vigor, deep green foliage, and overall health, particularly when preparing for the colder months and to bolster its winter hardiness down to USDA zone 6 conditions.
