Others, such as many conifers, have extensive root masses that spread far out from the base of the tree in search of resources. Alternatively, modeled trees initiated with root access to bedrock groundwater matched the hydraulics of the experimental trees by increasing their water uptake from bedrock groundwater when soil layers dried out. What shape/form do they have (e.g. Blocked drains and lifted paving may also be a problem. Your suffering conifers appear to be leylandii, which have shallow fibrous roots systems not deep as Mike suggests. Reproduction by the transfer of pollen produced in male cones. Seeds.

Conifers do not need much fertilizer and a light dressing of fish, blood and bone worked into the soil around the plants will be quite adequate. As part of the research, the team compared the behavior of modeled trees to that of real trees at the Los Alamos Survival-Mortality experiment site (pictured), where trees underwent drought and heat treatments. Conifers are trees with sharp, needle-like foliage that remains on the branches year round with only a few exceptions. More. Conifers generally don't require staking, but there are three exceptions: Those used in very windy locations may need to be staked, but for no more than a year, long enough for anchor roots to develop sufficiently to support the plants.
