About Mr Bowling Ball Arborvitae
Thuja occidentalis 'Bobozam' · also called Mr. Bowling Ball Arborvitae, Globe Arborvitae · flowering
A dwarf, naturally ball-shaped evergreen with fine, feathery, sage-green to blue-green threadlike foliage that gives a soft texture unlike typical arborvitae. It keeps a neat sphere without shearing and stays small, suiting borders, foundations, and containers. It thrives in full sun to part shade with moist, well-drained soil and is exceptionally low-maintenance and cold-hardy.
Ideal humidity: Ambient outdoor humidity
Watch for — Spider mites: Hot, dry conditions encourage mites that brown the delicate foliage; hose off and treat with horticultural oil if needed.
The watering schedule, season by season
Mr Bowling Ball Arborvitae flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for mr bowling ball arborvitae is twice weekly while establishing; weekly thereafter, 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 (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
- Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
- Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Keep soil evenly moist, especially the first two years. Drought-tolerant once established but the fine foliage can brown if it dries out badly; mulch to retain moisture.

How to tell mr bowling ball arborvitae needs water
A calendar is the worst way to water mr bowling ball arborvitae. 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.
- Leaves or flower stems lose turgor and start to droop.
- Buds stall or the pot feels light.
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 mr bowling ball arborvitae for a day is almost always safer than over-watering it.
Overwatering vs underwatering mr bowling ball arborvitae
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For mr bowling ball arborvitae specifically:
Signs you are overwatering
- Yellowing leaves, bud drop, and a heavy, constantly wet pot.
- Mushy stems or crown rot at soil level.
- Fungus gnats and a sour soil smell.
Signs you are underwatering
- Wilting, bud and flower drop, and crispy leaf edges.
- A faded, stressed look and a rootball that has pulled from the pot sides.
Erratic watering — bone dry then flooded — makes mr bowling ball arborvitae drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for mr bowling ball arborvitae unless your water is very hard; rainwater is a safe default if leaf tips brown.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For mr bowling ball arborvitae, the levers that matter most are:
- A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
- Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
- Empty the saucer after every water so the roots are never sitting in run-off.
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 mr bowling ball arborvitae.
