Describe the procedure of planting a tree.

Week 28

A

1) make sure tree is being planted in the correct place according to plans.
2) write a risk assessment or talk through job with colleagues
3) keep all of the plants roots damp at all times. Soak the root ball thoroughly.
4) select tools and equipment
5) dig hole, straight sides and deep enough to place turf upside down in the bottom of hole. Scarify the sides of the hole.
6) offer the plant to the hole and make adjustments to the hole.
8) mix well rotted compost and fertilizer with the soil ready to back fill.
9) place turf in the bottom of the hole and chop up.
10) prune any dead, damaged or diseased branches.
11) make sure tree is being planted at the same depth it came out of the ground.
12) for bare rooted plant, knock in a short stake vertically. Arrange roots around it and tie it at the correct height.
13) use a stick laid across the hole to make sure the tree is being planted at the correct depth.
14) fill the hole with the soil and compost, shaking tree if possible to ensure roots are in close contact with the soil, no air pockets. Use feet to gently firm soil as you go.
15) a stake can be knocked in at an angle, avoiding root ball, after planting.
16) water the tree well
Guard the tree from large pests if necessary
Mulch the tree with compost on a weed free surface, about 1m diameter.

Q

Describe the routine maintenance for trees and woody shrubs.

A

Weeding- especially for newly planted specimens. Hand weeding, mulching, hoeing.
Watering- water only when particularly dry, plenty infrequently. Young plants will need more frequent attention until roots spread out and down.
Mulching - supplying nutrients, suppressing weeds. 5-10cm deep.
Feeding - via mulching or as top dressing of fertilizer.
P&d control
Pruning

Q

Name some pests and diseases that attack woody plants.

A

Coral spot- fungus invading dead wood in a canopy and spreading to live wood.

Honey fungus - rhizomorphs spread in top 30cm of soil. Polythene ringing a shrub beyond root plate 45cm vertically into the soil may prevent attack.

Fireblight - bacterial infection entering blossoms, spreading down shoots and potentially killing off branches and whole plants. Scorched leaves.

Aphids, caterpillars and scale.
