Perennials Amy Jo Detweiler
2
Perennial plants that live for 2+ years once mature they flower annually
3
Herbaceous non-woody plants that die back and go dormant in winter
4
Perennial lifespan depends on type of plant, soil, climate, care, etc.
5
Perennial types: ground covers biennials border plants rock/alpine plants
6
Perennial types: herbs bulbs ornamental grasses water plants ferns
7
Planning & Design research visit nurseries, gardens neighbors consider time
8
Planning & Design yourself/professional consider site environment
9
Stats for The Dalles USDA Hardiness Zone 6-7 microclimates/frost dates annual precipitation ~ 14” soils – sandy loam/silty loam climate summary at http://www.ocs.orst.edu/
10
Design principles balance contrast repetition harmony unity dominance
12
Design Elements color texture flower fragrance
13
Design Elements bloom time seasonal interest function mature size
15
Formal Design symmetrical shaped beds straight lines
16
Informal Design asymmetrical shaped beds free-flowing beds
17
Low Maintenance non-invasive resistant sturdy stems adaptable short/long life span
18
Do a design sketch out use a garden hose consider hydrozones
20
Site considerations soil sun/shade wind bed/border existing features viewpoint
21
Plant material nurseries, greenhouse seeds neighbors mail order
22
Soil provides nutrients improves aeration address drainage concerns
23
Soil add organic matter 1/2-1/3 improve water holding capacity
24
Prepare the hole twice as wide as container, same depth amend with soil
25
Containers check out roots avoid planting dry root balls
26
Following planting water new plants in well irrigation type root stimulant optional mychorrhizae
27
Mychorrizae
28
Watering plants water deeply less often avoid water on foliage once established, as needed
29
Drip line
31
Irrigation Test dig down 6-8” ball up soil
32
Using Mulch reduce weeds/weed cloth prevents desiccation prevents erosion
33
Using Mulch covers bare ground 2-5” deep types
37
Maintenance fertilization weeding cutting back transplanting dividing
38
Maintenance winter watering ? pest management reapply mulch as needed
39
Fertilizing avoid direct contact with the roots wait for establishment increase the amount of nutrients available to the plant
40
Fertilizing spring feeding avoid late summer, early fall feedings slow-release, phosphate
41
Weeding weed cloth mulch within a bed
42
Cutting back encourage repeat bloom promote new growth control size
43
Transplanting in spring or fall redesigning mislocation
44
Why divide? decline in vigor becomes invasive for propagation
45
How to divide every 3-5 years early spring, late summer dig around drip line avoid root damage
46
Propagation seeds stem cuttings root cuttings grafting(advanced)
47
Seeding light soil moisten soil sprinkle seeds cover with thin layer of soil repot when larger
48
Stem cuttings in morning cut 3-5” remove bottom leaves dip in hormone place 1/2-1/3 in soil clear plastic
49
Root cuttings 1/4’+ wide roots, 3-4” long when plant is dormant plant upright when growth is seen transplant
50
Other uses cut flowers dried flowers
