About Hosta 'August Moon'
Hosta 'August Moon' · also called August Moon Hosta, August Moon Plantain Lily · flowering
Hosta 'August Moon' is a medium-large cultivar producing broad, rounded, softly puckered leaves that emerge chartreuse in spring and mature to a luminous golden-yellow by midsummer. It is notably sun-tolerant for a hosta and bears white, fragrant flowers in late summer. Toxic to dogs, cats, and horses.
Ideal humidity: 45-65%
Watch for — Yellowing in late summer: Some early leaf yellowing from late August is normal seasonal senescence as the plant begins dormancy, not a nutrient deficiency.
The watering schedule, season by season
Hosta 'August Moon' likes a soak-then-partly-dry rhythm — let the top of the soil dry before watering again, and never leave it standing in water. The base rhythm for hosta 'august moon' is when the top 3 cm of soil is dry, roughly every 6-7 days in summer, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 6-7 days.
- Autumn (slowing down): Autumn: growth slows, so stretch the interval and let it dry a little more between waterings.
- Winter (rest / dormancy): Winter: water noticeably less — often half as often — because low light and dormancy slow water use right down.
Regular, consistent watering maintains the large leaves in good condition. More sun exposure increases water demand. Mulching is recommended to reduce moisture loss between waterings.

How to tell hosta 'august moon' needs water
A calendar is the worst way to water hosta 'august moon'. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch (or a knuckle-deep finger test comes back dry).
- Lifting the pot, it feels distinctly light.
- Leaves droop slightly or lose a little of their gloss just before they truly need water.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering hosta 'august moon' for a day is almost always safer than over-watering it.
Overwatering vs underwatering hosta 'august moon'
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For hosta 'august moon' specifically:
Signs you are overwatering
- Yellowing lower leaves and a pot that stays wet and heavy for days.
- Soft, brown, mushy stems or a sour soil smell — root rot.
- Fungus gnats breeding in permanently damp soil.
Signs you are underwatering
- Drooping, curling leaves with crispy brown edges that perk up after watering.
- The rootball shrinks away from the pot and water runs straight down the sides.
- Slow growth and a generally tired, washed-out look.
Watering hosta 'august moon' on a fixed weekly calendar regardless of season is the most common mistake — in dim winter light the same routine drowns it. Check the soil, not the date.
Water quality notes
Tap water is generally fine for hosta 'august moon'. If your water is very hard and you see brown leaf tips, switch to filtered or rainwater.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For hosta 'august moon', the levers that matter most are:
- More light and warmth speed drying; the brighter the spot, the shorter the real interval.
- Pot size and material matter — small terracotta pots dry far faster than large glazed or plastic ones.
- Lifting the pot to feel its weight is more reliable than any calendar for judging when to water.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of hosta 'august moon'.
