What grows at 35.0645, -86.5914#
Generated 2026-10-09 from open data. These are starting points, not answers: check them against local knowledge, a soil test, and your own records.
The site#
- Climate class Cfa; average 15.4 °C; 1376 mm of rain a year; USDA hardiness zone about 8a.
- Last spring frost around March 31 and first fall frost around November 3; at least 207 frost-free days in 8 years of 10.
- 2774 growing degree days a year (°C, base 10); about 1048 chill hours in winter.
- Over the record, the later fifteen years were +0.5 °C warmer than the earlier fifteen.
- Soil: Dickson silt loam, 2 to 5 percent slopes — Moderately well drained, 4.0% slope; topsoil pH 6.2, organic matter 2.8%.
- Left bare, this soil would erode at about 26 times the rate it can tolerate: keep it covered — cover crops, perennial forage, buffers.
Climate is from NASA POWER's grid, tens of kilometres across: winter lows and frost dates in a field can be colder than shown.

Fruit trees by winter chill#
Winters here give at least 1090 chill hours (hours between 0 and 7.2 °C, November to March) 8 years in 10. Against published cultivar requirements — stone fruit compiled by Fadón and others (2020), apples by González Noguer and others (2023, the dessert and cider apples), pears measured by Fadón and others (2023) — taken in many countries and by several methods, so a guide, not a guarantee, this many cultivars of each would get their chill.
- Almond: 68 of 68 cultivars
- European apricot: 26 of 41 cultivars
- Japanese apricot (ume): 6 of 8 cultivars
- Peach: 115 of 126 cultivars
- Nectarine: 10 of 10 cultivars
- Flat peach: 7 of 7 cultivars
- European plum: 4 of 9 cultivars
- Japanese plum: 16 of 16 cultivars
- Cherry: 25 of 40 cultivars
- Apple: 55 of 78 cultivars
- Pear: 16 of 16 cultivars
Bloom and frost: for 185 cultivar estimates whose studies also give a heat requirement, bloom is simulated on this site's own winters — chill from November 1, then heat — and a year counts as frosted when the minimum falls to −2.2 °C (28 °F) or below within two weeks after bloom. The grid's minimums are milder than an orchard floor's, so the counts err low.
- Almond: blooms February 4 to March 12 (median February 20); frost after bloom in 8 years of 10.
- European apricot: blooms March 14 to April 15 (median March 23); frost after bloom in 3 years of 10. For 9 of its 32 estimates, chill falls short in more than 2 winters of 10.
- Japanese apricot (ume): blooms December 18 to March 21 (median February 28); frost after bloom in 7 years of 10. For 2 of its 6 estimates, chill falls short in more than 2 winters of 10.
- Peach: blooms March 19 to April 13 (median March 26); frost after bloom in 2 years of 10. For 5 of its 34 estimates, chill falls short in more than 2 winters of 10.
- Nectarine: blooms March 16 to April 2 (median March 21); frost after bloom in 4 years of 10.
- Japanese plum: blooms March 12 to April 5 (median March 27); frost after bloom in 2 years of 10.
- Cherry: blooms March 29 to April 30 (median April 28); frost after bloom in 0 years of 10.
- Apple: blooms April 7 to April 23 (median April 15); frost after bloom in 0 years of 10.
- Pear: blooms April 1 to April 5 (median April 3); frost after bloom in 1 years of 10.

For bees#
- Bees can fly here in February, March, April, May, June, July, August, September, October, November, December.
- Nothing on the list is recorded in flower in September, October, November: plant for those months. (A gap can also be missing data.)
For livestock#
- Dairy cattle face heat stress on 96 to 172 days a year: favour heat-tolerant breeds, shade and water.
When to propagate#
By the ways USDA PLANTS lists for each plant, in windows set by this site's median frost dates — common practice for each method, a first approximation. The plant-by-plant list is in propagation.csv.
- Seed that needs cold (67 plants): sow outdoors November 3 to December 1; March 31 to April 21 — the first after the fall frost, so winter stratifies it; the second for seed stratified cold and moist indoors.
- Seed (114 plants): March 31 to May 30. Food crops with a crop model have their own sowing windows above.
- Bare-root stock (101 plants), planted dormant: February 17 to April 14; November 3 to December 15.
- Container stock (117 plants), out of midsummer heat: March 31 to May 26; September 8 to November 3.
- Hardwood cuttings (65 plants), taken dormant: November 3 to February 17.
- Sprigs and sod (26 plants), in warm soil: April 14 to August 25.
- Tubers (2 plants): March 31 to April 28.
