Slide 2

Selecting Quality Trees from the Nursery Dr. Edward F. Gilman and Traci Partin

Slide 3

Poor versus great quality

Slide 4

Advantages to choosing quality trees Higher survival post-planting Greater life span in the scene Reduces timeframe required for foundation Reduces probability of disappointment from auxiliary imperfections amid a typhoon

Slide 5

Important contemplations for choice Production technique Maximum size at planting Root ball measurements Root neckline area Root abandons Root ball: caliper: stature relationship Trunk and branch structure Other

Slide 6

Tree creation strategies Balled in burlap (B&B) - root pruned preceding transplanting - not root pruned Container - over the ground - pot in pot - texture Bare root

Slide 7

Choose among tree generation techniques in view of weight and staking capacities * B&B = Balled-in-burlap

Slide 8

Tree survival in the scene can rely on upon the creation strategy and water system hones in the wake of planting * B&B = Balled-in-burlap

Slide 9

Tree survival in the scene can rely on upon the generation technique and water system rehearses subsequent to planting * B&B = Balled-in-burlap

Slide 10

Here is the synopsis story Under restricted water system: Root pruned, solidified off B&B – last beyond words – in the center Recently burrowed B&B – first incredible proper, escalated water system: It doesn't seem to make a difference

Slide 11

Oak not root pruned

Slide 12

Root pruned last generation year just

Slide 13

Root pruned a year ago and year before

Slide 14

One year in the wake of transplanting Not root pruned Root pruned last generation year Root pruned last 2 creation years

Slide 15

Conclusions about root pruning Root pruning amid creation gives an item that: 1) is somewhat littler 2) has a denser, more stringy root framework 3) has a more uniform root framework 4) transplants all the more effectively Note: Not all species require root pruning. Some have a thick stringy root framework without root pruning.

Slide 17

Selecting the correct tree estimate Irrigation capacities: When water system is constrained… Site seepage: If waste is poor… Weed control and mulch administration: If weeds are not controlled and contend with tree for water… … then select little nursery stock, for example, 1.5 to 3 inch caliper trees.

Slide 18

Tree estimate impacts tree foundation rate

Slide 19

Tree measure impacts tree foundation rate Percent caliper, tallness, and spread increment amongst May and October 2005 for live oak transplanted from #15 and #45 compartments to the field. ________________________________________________ Container % caliper % height % spread Size increase increment - - - - - #15 (1" caliper) 60.4a 36.5a 55.8a1 #45 (2.5" caliper) 14.8b 9.1 36.4b ________________________________________________

Slide 20

Conclusions about tree measure Smaller trees take less time and water to set up. Survival of littler nursery stock is more noteworthy if water system abilities are constrained. Development rate of little trees is altogether more prominent than when similar species is planted at a bigger size. Unless a lot of water can be provided, it is ideal to plant littler trees.

Slide 21

Important contemplations for determination Production strategy Maximum size at planting Root ball measurements Root neckline area Root absconds Root ball: caliper: tallness relationship Trunk and branch structure Other

Slide 22

Root ball measurements Root bundles of any shape perform similarly well in all around depleted soil. Tall root balls help keep further roots soggy. Wide and shallow root balls are more qualified for planting in ineffectively depleted and compacted locales. Shallow root balls dry faster on all around depleted locales.

Slide 23

Good for ineffectively depleted site

Slide 24

Important contemplations for determination Production technique Maximum size at planting Root ball measurements Root neckline area Root surrenders Root ball: caliper: tallness relationship Trunk and branch structure Other

Slide 25

Root neckline area Remove soil or media around the base of the storage compartment until you find the top-generally root. Root flare Top most root The top-most significant root ought to be inside 2-3" of the surface of the root ball.

Slide 26

Nicely situated root neckline

Slide 27

Trunk without flare ought to trigger a root check

Slide 28

Planted too profoundly Soil level Roots produced in the wake of planting Most normal Original top root Less basic No roots created in the wake of planting

Slide 29

Conclusions about trees planted too profound Do not buy the tree. Soil, media, and roots becoming over the first top-most root ought to be for the most part evacuated preceding planting.

Important contemplations for determination Production strategy Maximum size at planting Root ball measurements Root neckline area Root absconds Root ball: caliper: stature relationship Trunk and branch structure Other

Slide 31

Types of root imperfections Circling roots Kinked roots Girdling roots Root-bound

Slide 32

Circling roots Notice roots hovering at the top and sides of the root ball. Revolving around roots create when trees are developed in holders for a drawn out period, making roots be avoided by the compartment divider and to hover the outside of the root ball.

Slide 33

This tree was discovered inclining after a typhoon. The cause … surrounding roots

Slide 34

Kinked roots Kinked root Kinked roots happen if roots are collapsed into an engendering bed at the seedling stage.

Slide 35

Girdling root Girdling roots are framed when recovered roots develop opposite to a cut root, or from developing in a compartment too long. As the tree develops, these roots may meet the storage compartment and start to choke it.

Slide 36

Girdling root cuts down a monster Indented trunk

Slide 37

Root-bound Root-bound trees have many roots hovering around the outside of the root ball. This causes a physical obstruction, keeping the tree from spreading roots into the scene soil in the wake of planting.

Slide 38

Many roots inside however few on the edge of root ball demonstrate quality.

Slide 39

Quick test for root quality Good Quality Poor Quality Trunk does not twist Trunk twists

Slide 40

Conclusions about root abandons Root surrenders significantly affect tree execution in the scene. Deformities can happen on all trees paying little mind to the creation strategy. Issues are less demanding to amend in the nursery when the tree is youthful; some revision can happen at the season of planting.

Slide 42

Root ball models

Slide 43

Way over-developed

Slide 44

Conclusions about root: stature proportion Ideally, the measurements of the root ball ought to surpass the base that is prescribed.

Slide 45

Important contemplations for choice Production technique Maximum size at planting Root ball measurements Root neckline area Root abandons Root ball: caliper: stature relationship Trunk and branch structure Other

Slide 46

Trunk structure Shade trees of lesser quality have at least two trunks Best quality shade trees have one prevailing trunk low quality best quality great quality

Slide 47

Branch course of action Good quality Poor quality Major branches and trunks ought not touch. Branches ought to be under 2/3 trunk measurement. Principle branches on shade trees ought to be separated.

Slide 48

Young quality tree Small brief branches are OK Lower branches help the root framework and lower trunk develop Protects trunk by shaping a hindrance to mechanical harm.

Slide 49

Poor quality Codominant stems Major branches/trunks touching V-formed groin Included bark

Slide 50

Conclusions about structure Choose trees that have been prepared in the nursery to have great structure. Trees with great shape at time of planting will require upkeep to keep one prevailing trunk. Trees with poor structure will require more extreme and tedious pruning visits.

Slide 52

Other elements impacting tree quality Trunk damage Trunk harm or broken branches. Tree wrap (might conceal wounds). Illness or creepy crawly harm. Overhang consistency and totality. Nature of old pruning cuts. Seed or propagule source. Foliage shading and size. Nearness of stakes. Tree wrap

Slide 53

Carefully investigate the tree for infection or creepy crawly harm.

Slide 54

Canopy consistency and totality Good consistency and completion Poor consistency and completion

Slide 55

Quality of old pruning cuts Flush cut Good cut Callus shaping just around sides of flush cut. Branch neckline do not present anymore.

Slide 56

Seed or propagule source

Slide 57

Foliage shading and size

Slide 58

Presence of stakes Stake

Slide 59
