User Story:
As an incoming Gardening Manager, I want the system to automatically generate a task for me when I am designated as the manager of a newly created garden record, so I am promptly informed and can take necessary action to acquire plants for the garden.

Acceptance Criteria:

1. When a new garden record is created and a manager is assigned, create a new Task record and assign it to the manager
2. The subject of the task should be "Acquire Plants"
3. The task should be linked to the garden record

• The task should only be created when a garden record is first created AND the manager field is populated
  
  

Field Mapping

Example:

• If a garden record is created with a manager, a task should be created
• If a garden record is created without a manager, a task should not be created
• If a garden record is updated with a manager, a task should not be created (we'll do that next)
