Water ratings
What an established plant needs to thrive in the growing season, from the City of Austin's Grow Green guide:
- Very low
- Water occasionally, if no significant rainfall for 30 days.
- Low
- Water thoroughly every 3–4 weeks if no significant rainfall.
- Medium
- Water thoroughly every 2–3 weeks if no significant rainfall. Most of the guide's Medium plants prefer shade, so the soil dries out more slowly.
- High
- Water thoroughly every 5–7 days if no rainfall. Plant these where the ground stays naturally moist or gets stormwater runoff.
A Low-rated plant often survives on rain alone, though it may not thrive. New plants need more, sometimes daily, until established.
