lecture 14 Flashcards
what are the advantages of container gardening? (10)
good for beginners
can be moved - protect from unfavourable conditions
Suitable for small spaces - verticle & balconies etc.
flexibility
Can control soil/media, drainage, water, etc.
less weeding
protect from pests
Fewer soil-borne pathogens
Many different materials
accommodate disabilities
what are the disadvantages of container gardening?
watering - more frequent than ground
nutrients (may need to add more)
wt
not suitable for some plant types
what are possible materials for container gardening?
Pots, pails, wooden boxes,
what factors should be considered when selecting materials for container gardening? (7)
consider wt
Clay & porous materials dry out and accumulate salt residues
size of pot should match plant (4:1)
drainage
colour
cost
aesthetics
what are the advantages of raised beds? (10)
Eliminate probs with thin, poor, or contaminated soils
can control soil mix used
drainage
more intensive production
Water use efficiency
easier weed control
accessibility
can be covered
can adapt to automated watering
flexible design options
what are the disadvantages of raised beds?
cost
aesthetics
what factors need to be considered when designing raised beds? (5)
location
shape & size
space b/w multiple beds
materials
fits location & purpose
what is a desirable exposure to sun for raised beds?
min 8 hrs per day
North - South orientation better than East – West
what factors should be considered about the location of raised beds?
exposure to sun
flat surface
surface type
access to water
room to work
what determines how deep the raised beds should be?
depends on what you’re growing
what factors should be considered about the shape & size of raised beds?
accessible from edge
Length flexible if have side access
depth
what factors should be considered about the space b/w multiple beds of raised beds?
people only? - 18-24 inches
wheelbarrow width
wheelchair
other tools
what factors should be considered about the space b/w multiple beds of wheelchair accessible raised beds?
May need to increase height of bed
surface b/w beds is important
what factors should be considered about the materials of raised beds?
durabilty
cost
ease of construction
what is the most common material used for raised beds?
wood
what are possible materials for raised beds? (5)
wood
bricks
concrete blocks
logs
modeled plastic
what should be done if raised beds are being constructed on a grass surface?
Best to “smother” grass and break up sod before placing bed
Allows root penetration beyond depth of bed
how do you treat an area of a raised bed if it is a potentially contaminated site? (4)
Remove contaminated surface layer if possible
Line bottom to prevent root penetration & mixing soil
Do not compromise drainage
Cover areas b/w beds to reduce exposure to contaminants via dust & transfer to clothing/footwear
what are the advantages of an in-ground garden?
inexperience
Efficient use of horizontal space
Makes use of available resources
easier water management
Good when you have good soil, drainage, etc.
what are the disadvantages of an in-ground garden?
Only as good as the soil, exposure, etc. will allow
may require more work
more difficult to protect from pests
May take time to improve productivity
when terminating grass, why is it disadvantageous to lift & remove the sod?
Takes away a productive layer of soil
when terminating grass, why is tilling disadvantageous?
Many grasses difficult to terminate this way due to vegetative propagation
when terminating grass, what are the probs with herbicides?
Difficult to get 100% control - may need multiple applications
what is a good herbicide to use to terminate grass?
weedZap
