Common Name:
Common persimmon

Species Code:
DIOVIR

Ecotype:
South Central Missouri

General Distribution:
Common persimmon is found throughout the eastern and central United States, from New York west to Iowa and Nebraska and south to Texas and Florida. It inhabits rich bottomlands and coastal plains forests. Our seed sources are from south central Missouri.

Known Invasiveness:

Propagation Goal:
plants

Propagation Method:
seed

Product Type:
Bareroot (field grown)

Stock Type:
1+0

Grow Time:
1 Years

Target Specifications:
Height: 24 to 36 in
Caliper:0.25 to 0.50 in
Root System: Root system must balance top growth.

Propagation Collection:
Seeds are purchased from local people who collect within a 50 mile radius of the nursery. The fruits are green to yellow to almost black at maturity, each containing 3 to 5 seeds.

Propagation Processing/Propagule Characteristics:
We use a Dyb-Vig to clean seeds. We air dry seeds on stacked, ventilated screens. Seeds are dried to less than 10% seed moisture content prior to storage.
There are 1,460 to 3,880 seeds per kilogram (665 to 1,764 seeds per pound)(Olson and others 2004).
We store our seeds in sealed plastic bags inside sealed plastic tubs in a cooler at 36 F.

Pre-Planting Propagule Treatments:
We plant seeds by hand in late October into prepared field beds.

Growing Area Preparation / Annual Practices for Perennial Crops:
Soils: Our field soils are silty clay loams.
The spring before planting, we amend the soils with 700 lbs/acre of 1N:3 P205:5K20, grow a soybean cover crop, and fumigate in the fall. We use Roundup Ready soybeans so we can control weeds by using glycosate herbicide without harming the cover crop. During early August, we disk under the cover crop and disk the soils several times during the next 6 weeks to obtain a smooth soil surface. Soils are fumigated in late September. Field Bed Preparation: We mark out and form beds as needed. Beds are prepared with a rototiller/seedbed former and are typically 4 to 6 inches high and 4 ft wide. Fields are cultivated for weeds as needed throughout the growing season.
Irrigation: We use overhead irrigation with two inch pvc pipe that can be moved from field to field each year. Our principle water source is from 3 on-site wells and is very good quality water.

Establishment Phase:
We sow seeds at least 2 inches deep to protect them from deer, rodents and birds. Seeds are covered and irrigated when soils appear to be drying out on warm days. We apply old sawdust and hydromulch after sowing.

Length of Establishment Phase:
1 month after emergence in the spring

Active Growth Phase:
Year 1: Fertilization: We apply ammonium sulfate 21-0-0-24 with a mechanical spreader. We put on the first application the last week of May and to only those 1+0 seedlings that have been germinated for at least 5 or 6 weeks. We put down our last application during the last week of July. We apply fertilizer at the rate of 125 lbs/acre. Frequency of application depends on the species and how they look that season. We irrigate for at least 45 minutes following all fertilizer applications. This insures that foliage will not burn and incorporates fertilizer into the root zone.
ROOT PRUNING PROCEDURES: Seedlings are root pruned during June. Pruning depth is at least 10 inches for 1+ 0 stock. Irrigate heavily for 2 to 3 days prior to pruning to saturate the root zone. Set pruning blade to slightly wrench seedlings as they are pruned. Check pruning depth frequently and adjust as needed. Irrigate for a minimum of 2 hours following root pruning to settle soil back around roots. This step is critical to eliminate post root pruning mortality. Irrigate field heavily for 2 to 3 days to further settle the soil.
TOP PRUNING PROCEDURES: We top prune only to keep seedlings from being damaged by the mechanical lifter. Our clients prefer seedlings that have not been severely shoot pruned.

Length of Active Growth Phase:
4-5 months

Hardening Phase:
Hardening begins during August. No fertilizer is applied after August. Irrigation frequency and duration is shortened and applied only when needed.

Length of Hardening Phase:
2-3 months

Harvesting, Storage and Shipping:
Lifting window is from late November to April, depending on species. We try to obtain a large a root mass as possible. We try to lift when the majority of leaves have dropped. Seedlings are hand lifted after the seedling beds have been undercut at an average depth of 10 or 12 inches using a lifter. Lifted nursery stock is immediately stored in cooler until graded and bundled. The majority of species are graded, bundled and shipped during February.

Length of Storage:
3 months
