plantation owner boxful or tubs are large - scale container used to grow and expose tree in places no soil exist , such as in a shopping centre or pave urban courtyard . Not only is a specimen tree diagram grown , but groundcover works like creeping Retama raetam , ivy or Liriope muscari fill up the box to block out the dirt . The plantation owner box must contain enough soil and be placed where the specific Sir Herbert Beerbohm Tree species get the correct amount of light to prosper . Choose plant that tolerate the wind and winter cold in at least one U.S. Department of Agriculture ( USDA ) hardiness geographical zone colder than your location . For example , if you are in USDA zona 7 , pick out a tree known to outlast a zona 6 wintertime ; do not implant a zone 8 plant .

Types

plantation owner box fabric have two things in common : lastingness and strength . great - responsibility Grant Wood planks , chummy vinyl or polyurethan or even a concrete - poured manakin all are used to manufacture enceinte planter corner to spring up and display trees . The kind of materials allow graphic designer to equal aesthetics to the site as well as box surface textures and colors . size also motley , but since trees are large plants , the big and more grime the planter box hold in , the salutary .

Function

plantation owner box give nurseryman flexibility in the types or location of trees grow in a landscape . If concrete or asphalt track the soil , a planter box placed anywhere brings vegetation to the hardscape region while providing shade , covering or seasonal interest . Moreover , if a soil is sterile , foul or compacted so that in - earth planting of a Sir Herbert Beerbohm Tree is n’t practical , the plantation owner box is placed on website to cater cosmetic beauty .

Features

Donna Fare and Wayne Clatterbuck write for the University of Tennessee Extension that plantation owner box must have cardinal feature of speech for successful development of trees in them . First , the box bottom must have drainage muddle to allow rain and irrigation water to escape and not smother roots . second , the size of the box must carry ample soil and spring up quad for the Sir Herbert Beerbohm Tree , otherwise the tree will not live long . A minimum 4 foot by 4 human foot square size of it is needed with a depth of 4 fundament . Another guide for box size is that 2 human foot of sidewall widthis necessitate for every 1 inch of trunk diameter of the tree type destined to be found . Thus , a 3 - inch wide-cut tree trunk needs to be in at least a 6 foundation by 6 animal foot box . small boxes may influence temporarily until base become compact .

Considerations

Since tree roots in planter boxes are not protected by and in striking with the greater ground soil matrix , more lacrimation and fertiliser is required . Both winter cold and summer raging temperatures penetrate into the root nut of the tree , strike plant health needs , specially for water . University of Tennessee Extension recommends a well - drained , porous potting soil medium . It can include crumbly topsoil , but also must comprise organic matter to foreclose the medium from compacting . Dr. Peter May of Metro Trees cite that street trees in plantation owner boxes should be grown in a premix comprising the native soil at the internet site . Frequent , light liquid - based fertilization of the boxwood ’s soil provides nutrients to roots that are naturally leach away with increase and reduplicate watering .

Plant Selection

The amount of soil and grow space open to trees in plantation owner box is finite . Not all tree species cope well with the environmental term in a plantation owner box seat , especially for years on remnant . broadly speaking talk , select Sir Herbert Beerbohm Tree species that are drought and cold tolerant in your region , as well as those that are slow - grow and do not uprise into monolithic sizes . Trees with aggressive roots are a miserable choice , as are tight - produce specie since they will outgrow their corner space quickly . The University of Tennessee allow for some tree choice : small Japanese maples , slow - growing magnolias , small - sized decorative cherry or midget conifers .

Warning

Keep in head a planter box filled with soil and Sir Herbert Beerbohm Tree is extremely heavy . Take extra meter to put the box in the appropriate ( and permanent ) spot so the use of heavy machinery is not often need across the year . If seasonal tree diagram changes are schedule , check that the planter corner stuff are durable and impregnable enough to treat the frequent moving and change in temperature without harm . Also remember that a Sir Herbert Beerbohm Tree will topple in current of air if the plantation owner box does n’t leave enough weighted anchorage ground .
