	* When to to replace? Best time of year to plant trees is late in the year (November etc). The majority of root growth happens in January- February-March, so if a newly planted tree can develop a larger root system during this time, supplemental water demands in spring and summer will be less. Most likely if you plant around November, you could get by with bi-monthly watering of a young/newly-planted tree; if you plant in the spring/summer, it is necessary to water 2-3x a week. Thus more room for failure. So, although the old tree can be removed now (pending owner approval!), we should wait until Winter 2015 to plant any new tree.		* When to to replace?

	* The Italian Cypress no longer grow in the manner typical of Cypress in the wild, which is more 'up' than 'out' -- i.e. normally more cylindrical/conical than spherical. This change to their typical shape is due to incorrect care for the trees in previous years: The Cypress were at some point(s) in time 'topped' by the owner (apparently in an attempt to stop rats from climbing the trees to the roof). Its also probable the tools used for topping at the time were not properly sanitized beforehand, they were not pruned at the right time of year, etc. In layman's terms (the only terms in which I can speak about this), this previous topping caused the trees to basically become confused about which other branch(es) were to be the 'new' top of the tree: The topping caused a hormone to be released that in turn caused various lower branches to each think they might be the new treetop. Lower branches began to grow more outward in various idiosyncratic ways, leading to outward bulges in various places on the trees, ultimately resulting in the trees losing their typical conical shape.		* The Italian Cypress no longer grow in the manner typical of Cypress in the wild, which is normally more 'up' than 'out' -- i.e. normally more cylindrical/conical than spherical.
