flag patios or walkways can make attractive and hard-nosed landscape feature . Although a flagstone patio can improve a yard or garden ’s esthetic , it can also have an unintended negative effect on trees or bush whose tooth root system of rules are paved over or otherwise affected by construction . If the terrace must be placed near the tree , there are certain stone - laying method that will minimise the effect of the stones on the tree .
Step 1
A tree ’s radical system ply vital functions for whole Sir Herbert Beerbohm Tree health , including food and water uptake , energy storage and ground the tree . Most of a tree ’s antecedent system of rules is locate within the top few feet of soil . The upright manner to ensure that a tree will continue healthy is to settle the terrace or walkway outside the tree diagram ’s protect ancestor geographical zone , the area of the ground within the tree ’s drip line . However , for many projects , this spacing is not feasible . In this case , the University of Minnesota extension recommends disturbing no more than 25 percent of the source located within a tree ’s drip line . The characteristics of individual tree species should also determine construction considerations . Some Tree can withstand more antecedent scathe than others . to boot , Sir Herbert Beerbohm Tree root can originate near or above the ground surface and lift the flag .
Step 2
Laying the Flagstone
Certain flagstone - laying methods or option will help understate the effect of the patio on the roots and can also aid forbid large surface ancestor from push up the flag . Curtis W. Smith of the New Mexico State University Cooperative Extension Service recommends using lamp chimney flue roofing tile with one side removed to create a sort of bridge to make a burrow that give up for tooth root enlargement and breeze telephone exchange . Avoid digging or making cut into the ground during raging , dry weather , do all toil by hand , water the tree on a regular basis and apply mulch to the undercoat around the undertaking area . Do not use trench mortar or concrete underneath or between the flagstone . Instead , use a substructure and infill of crushed rock , pea plant gravel or sand that will appropriate moisture and air to pass roots .
Tree Care After Patio Construction
Certain steps can be take after the source - damage activeness in ordering to cut back impairment . The destruction of rootage and compaction diminish the tree diagram ’s power to take up water and nutrient , but disciplinal action can help . Thin out branches selectively to reduce the tree ’s piss requirements , water the tree on a regular basis so it has adequate moisture and consider applying plant food that will stimulate solution growth . Avoid using excessive nitrogen .
Recognizing Damage to Trees
Careful monitoring of the tree after placement of the flagstone patio will take into account for the straightaway recognition of building - connect harm and may indicate a need for corrective legal action . A tree diagram suffering the effects of rootage harm will often endure from wilt , folio distortion and other leaf drop . Adjust the care regimen and mitigate any construction damage if potential . A importantly affected or particularly raw tree can also decline enough that it eventually dies and fails to leaf out during the following growing season . In this shell , the Sir Herbert Beerbohm Tree should be removed and the patio setup should be adapt or a more suitable Sir Herbert Beerbohm Tree specimen should be planted .
