Preparing the Planting Site
#12
Basic Steps
Whether you're growing flowers, vegetables, shrubs or trees, the basic steps for preparing the beds for planting are similar: – – – – – 1. Site Analysis 2. Laying Out New Beds 3. Removing Sod/Weeds 4. Preparing Soil 5. Finishing Borders
Site Analysis
Know your site above and below the ground There are three main planting site characteristics that will influence how plants will thrive These three characteristics are – – – – Soil type and condition Drainage Availability of light
Below the Ground Soil Type
Three Basic Soil Types
Sand soils
- have easily detectable particles and are gritty in texture; water retention is very poor, and they are more resistant to compaction and have minimal nutrient value.
Loam soils
- have relatively equal proportions of sand, silt and clay; feel smooth but there is evidence of graininess; have some nutrient value, and have fair to good moisture retention.
Clay soils
- have very fine particles, smooth texture, retard the movement of water, contain high nutrient value and compact easily when wet
Native Soil vs Desirable Soil
pH Texture Drainage Fertile
Below the Ground Soil Texture
Fine Texture Clay – compact – poorly drained – low oxygen # 1 cause of plant decline in Georgia
Below the Ground Soil Test
Soil pH
pH governs the availability of nutrients & activity level of microorganisms
Below the Ground Soil pH
Most plants can grow in a soil pH 5.5 - 7.0
Low pH < than 5.0 (acidic soil) – Dolomite or Limestone High pH > 7.0 (alkaline soil) – Ammonium sulfate , Aluminum sulfate, Sulfuric acid
Below the Ground Soil Drainage
Good Drainage : water drains in 2 hours Fair Drainage : water drains in several hours Poor Drainage : 8-10 hours water still there
Above the Ground SITE ANALYSIS
Sun Exposure – Full sun – Part sun – Part shade – Shade
Above the Ground Wind Flow
Wind – increase the amount of water loss from plants – big problem if root space is limited or poorly drained soil (lack of root development)
Laying Out New Beds
A garden hose is often the best tool for establishing the new boundaries First, lay it out approximately where you want it. Then, flex the hose as needed to achieve the best looking layout.
Laying Out New Beds
If you're working off a plan and exact dimensions are critical: – – – – Choose a landmark on the plan (like a corner of the house or lot) Determine the lengths at right angles from that to the bed's boundaries on the plan Measure those same lengths off the landmark in your yard Lay the hose through those points to get the boundaries exact.
Removing Present Vegetation
Once you've determined the boundaries for the beds, you can remove the sod or whatever vegetation falls within the boundaries – Chemically: Post Emergence Herbicide
Removing Sod
First, cut into the sod down to the soil along your boundary line using a square-nose shovel.
Next, use the shovel to pry up the edge of the sod down to the soil and push the shovel in between the sod and the soil as level as you can get it to cut the sod away.
Sod Cutter
For larger beds, a gas operated sod cutter can be used Front blade slices the sod away from the soil
Preparing Soil
Area should be turned and dug to a minimum depth of 12 inches and minimum width of 3x the canopy
Amend the soil
Organic Materials Improve Drainage Till 4 to 6 inches of decomposed materials into the entire planting area to a depth of 12 inches
Types of Organic Materials
Decomposed – – Animal Manure Bark – Peat Moss – Grass Clippings – Leaves – Wood Chips – Sewage Sludge
Compost an Organic Material
Elevate Beds
Increase drainage Decrease soil compaction 30% greater growth
Soil Sample and Analysis
Determining the fertility level of a soil through a soil test is the first step in planning a sound lime and fertilization program for the home landscape and garden.
Lime & Fertilizer Recommendations
Based on your soil sample analysis add needed lime and nutrients to site.
Finishing the Borders
For a simple, natural look, you can finish your new beds with a
beveled edge
.
Just dig down along the edge about 4 inches deep, pushing the soil back into the bed and leaving a gap between the bed and the edge. Then shape the soil so it slopes down to the bottom of the new edge at a 45 degree angle.
Install Edging
Dig down about 6 inches along the edge of the bed, keeping the outside edge fairly plumb. Set the edging against that outside edge. Backfill the loose soil against the edging. Compact the soil to embed the edging firmly. Concrete curbing can be laid by machine
Definition of Bed
If you use edging material or not, show a definition between lawn and bed.
