Mutsu Apple
Large green-yellow fruit with firm flesh and a sweet, mildly tart flavor. Late season. Tree size, anchorage and drought response depend strongly on the grafted rootstock; full sun, drainage, compatible pollination and annual crop management are essential.
Profile
- Fruit
- Large green-yellow fruit with firm flesh and a sweet, mildly tart flavor.
- Harvest
- Late season. Timing shifts with region and weather.
- Cultivar distinction
- Also called Crispin; triploid Golden Delicious × Indo cultivar and poor pollenizer.
- Pollination
- Triploid: needs compatible pollen and is a poor pollenizer; ensure other trees can pollinate one another.
Water & soil targets
- Moisture (VWC)
- Site-calibrated; varies by soil and rootstock
- Salinity tolerance
- Sensitive to saline irrigation; rootstock affects response, but salt accumulation can reduce growth and fruit quality.
- Drought tolerance
- Limited to moderate; fruiting and dwarf-rootstock trees need reliable moisture.
Optimal root measurement depth
8–18 in
Most absorbing tree roots live in the upper 12–18 inches, out toward the drip line. Typical guidance; confirm with a soil probe on site.
Allow room for its vigorous growth and maintain even root-zone moisture; use separate compatible pollenizers and do not attribute poor set solely to irrigation. Wet the active root zone, keep the graft union and trunk base clear, and let drainage restore aeration between irrigations.
Problems to watch
- Blister spot on fruit
- Codling moth or locally important fruit insects
- Fire blight, apple scab or cankers according to local pressure
Stress signs
- Persistent leaf wilting or marginal scorch
- Reduced shoot extension and undersized fruit
- Premature leaf or fruit drop
Where you'll find it
- Fresh fruit
- Baking and processing
