Where are they?

Are plants in public, private, or utility/work area?

 

Need higher maintenance

  • Highly visible
  • Containers

Timing & Placement of

Plant Nutrients

save money and frustration

 

When?

  • WHEN NECESSARY!
  • Newly planted
  • Under stress (pruned, construction, pest pressure)
  • Mixedplantings (i.e. trees, shrubs,herbaceous)
  • Spring & very lightly in fall when planting

 

Where?

  • At ‘‘feeder‘‘ roots

beyond plant  canopy

  • Surface broadcast

(under mulch)

  • Incorporated into bed/planting hole
  • Foliar
  • Injected (trees)

Recommendations

  • General
  • Slow release (WIN 50% minimum)

(IBDU, sulfur-coated urea, resin-coated urea, nitroform, Osmocote)

  • Incorporated
  • To establish
  • With moderate N, P?, & low K
  • 1-4 lbs. of N/1000ft2/year (split application)
  • Shade areas less
  • Sand more frequent applications

Specific Recommendations
based on area, soil test, species, mgt. goals
– Annuals – photo
– quick release + slow release, high P & K
– incorporated into the entire bed

– Bulbs – photo
– after bloom, high P & K, bonemeal

Perennials – photo

– higher P & K for roots & flowers

– early spring for nutrients over season

– lightly for perennials planted in fall for

root growth

– around established plants

– in the hole for new plants

 

Trees & shrubs (1-4 lbs N/1000ft/year)

– Newly planted – yearly, 3-4 lbs N

– Mature/established – every 3-4 years, 1-2 lbs N

-Hollies & junipers – less

– Red tip, roses, English  laurels – more

– Ericaceous (azalea, rhododendrons, pieris, mountain laurels, camellias,  pH 4.5-6.0  -very lightly due to shallow  roots                         5#

– In early spring for season

– From dripline of established plants

– In hole for new plants

 

Chemical fertilizers, analysis, speed of reaction and effect on soil pH.

Other nutrient sources

  • Compost
  • Soil conditioners
  • Organic mulches
  • •Manures

 

Over/improper  Fertilization

  • pH change – deficiencies
  • Root damage
  • Crown damage,  death
  • ‘‘Burn‘‘

– marginal leaf necrosis from high salinity

– similar to injury from

drought

  • Surface & groundwater contamination

 

Situations that don’t need added nutrients

  • Buffer areas
  • Infiltration trenches
  • Rain gardens
  • Bioretention basins
  • Wetlands
  • Green roofs
