What you will be able to do
- Assess root-zone moisture with more than one check, and explain why the surface, moss, a probe meter, or a tag's schedule is not enough evidence.
- Explain why a tree's water use changes with weather, light, season, growth, container, and substrate.
- Explain and choose a watering method that wets the whole root ball and lets it drain, and name the checks that confirm it did.
- Tell a watering decision apart from a problem that needs investigating, such as wilting in a wet pot.
- Plan a checking routine and a holiday arrangement that hold up through changing weather and time away, and read a watering record for patterns that call for a change in care.

- Lesson 2: Reading moisture below the surface how to tell whether your tree needs water today.
- Lesson 3: How to water effectively how to water so the whole root ball wets, not just the surface.
- Lesson 4: Drying, saturation, and root oxygen why a tree can droop in a wet pot, and what to check first.

- Lesson 5: Rain, water quality, and unusual conditions18 min
Did the rain water the tree, and when does the water itself or the weather change the plan?
- Lesson 6: Building a routine that survives real life18 min
How do you keep a tree watered through busy weeks, changing weather, and time away?

How completion works
- Read and explore. Take the lessons in order or jump to what you need. When you finish one, mark it complete.
- Pass the quizzes. Each of the 2 quizzes is untimed and open book, passes at 80%, explains every answer, and can be retaken as often as you like. Your best result is saved.
- Earn your certificate. When every lesson is complete and every quiz is passed, your Certificate of Course Completion is issued automatically and appears on your dashboard.
The certificate records your coursework. It does not certify hands-on technique or the readiness of any particular tree.
