Plant Spacings
Plant Spacings values are used to calculate planting numbers for Area Planting and Linear Planting. If values are displayed for single plant labels, plant quantities in labels and schedules (reports) are based on the number of items individual plant components selected.

The Labels area is divided into 'Header' and 'Details' and users are able to define what information is displayed in either section and whether or not each is displayed (shown).

Header and Details are defined from a combination of 'expressions' and 'free text'.
Label Headers are stacked above Item Details and can be applied for both single species planting labels or for planting mixes (comprising a mix name and associated planting components, specifications and percentages).
Users are able to alter the percentage coverage for linear or area planting by entering a value in the Coverage % field. Note this is not available for individual plants that are part of a Planting Mix.

Users are able to change the slope factor for linear and area planting (single species or mixes) by selecting a value from the Level pop-down menu.

Characteristics
The View Characteristics command is available at the bottom left of the Edit Planting dialog. Note that the View Characteristics option is only available for single planting species.
