Fruit: Generally a medium sized, but may be larger, round to conic, regular to slightly angular shaped apple. Subject to severe russet formation, especially on the stem-end and the basin, in most seasons. Moderately susceptible to scarfskin. Lenticels are prominent and tan colored. Fruit are moderately susceptible to corking. Flesh is above average in firmness, is somewhat crisp, and juicy. The texture is fine and somewhat tough and the skin is tough and chewy. The flavor is tart to very tart at low starch index ratings (S.I. 3 to 5) but improves to subacid with a good mix of sugar at S.I. of 6 to 7. Storage life appears to be good (maybe 3 months, or slightly longer) for a late summer maturing apple.  Shelf life is more than 5 days, but the skin becomes greasy after extended exposure at room temperatures. Arlet is susceptible to bitter rot and apple scab.  Low susceptibility to plum curculio.  Moderately susceptible to tarnished plant bug, codling moth, oriental fruit moth, tufted apple bud moth and redbanded leafroller.

Tree: A low to moderately vigorous tree with spreading, somewhat open canopy. Arlet is precocious but only moderately productive. Trees are moderately susceptible to mildew and cedar apple rust and appear to be susceptible to fire blight.  Moderately susceptible to rosy apple aphid, European red mite, Japanese beetle, spotted tentiform leafminer and white apple leafhopper.  In the year of planting, Arlet trees showed good resistance to leafhoppers. Bloom has been early on Arlet planted at Kearneysville, WV.
