When seedlings arrive, keep the seedling roots protected and moist. Begin planting as soon as possible.
To store for two weeks or less
- Put the bales in a cool, shaded place.
- Separate the bales (to avoid overheating and molding).
- Pour cold water into the open end of the bales often enough to keep seedling roots moist.
- Do not store trees in water because roots may be damaged.
- Protect from severe freezing.
To store for more than two weeks
- Either hold bales in cold storage at 35 to 37 degrees Fahrenheit, or
- Put trees in a heeling-in trench.
- Dig trench in a shaded, protected place. Adjust depth to fit the roots (Figure 2). Avoid areas with high rodent populations.
- Cut bundle strings and spread trees.
- Pour water on roots as trench is being refilled with soil.
- Water as often as necessary thereafter to keep soil moist, but avoid overwatering.
- A mulch placed on soil close to trees will help hold moisture.
- Once the trees have begun growing, it is best not to remove them from the heeling-in bed until the following spring.
Never leave open bales of seedlings exposed to the sun and wind. During planting operations, take out a few bundles of trees at a time. Cover the others and keep them cool and moist until they are needed. Be careful to avoid damaging the terminal buds.
- Always carry seedlings in a bucket half-full of water or wet moss. Don't allow seedling roots to become dry. Do not store the trees with their roots in water.
- On unprepared areas scalp or skin off the sod and weeds from a spot 18 inches in diameter where each tree is to be planted.
- Center or side-hole methods of hand planting are shown in Figure 3.
- Slit method of planting with a grubbing hoe is shown in Figure 4.
- Slit method of planting with a tree planting bar is shown in Figure 5.
- Dig hole to fit root system.
- Set at same depth trees grew in nursery.
- Fill hole half full of soil and tamp well.
- Finish filling hole and tamp with feet.
- Use a three- or four-person crew. One person follows the machine to straighten and pack poorly planted trees. Another keeps seedlings protected, separated, and ready to load into planting machine trays.
- Trees in planting trays should be kept covered at all times with wet burlap or wet moss. This is important
If roots are exposed to the sun and wind, the trees may be dead before they are planted.
- Run the machine deep enough to allow the roots to hang down straight in planting slit
Typical depth is 8 to 10 inches. If soil is too rocky or hard to permit machine planting, plant by hand.
- Set seedlings at same depth or just slightly deeper than they grew in the nursery seed bed
Care of plantations
Livestock damage trees of all ages, so keep livestock out of your plantations.
Protect trees from fire. Plow or disk a fire break if necessary, and maintain it during the fire season.
Prevent rank growth of weeds and grass on good soils by cultivating, using proper chemicals, disking, mowing, or hoeing as often as necessary for the first two or three years. On poor soils, a light growth of vegetation such as broomsedge or ragweed provides some protection and may be beneficial.
Inspect plantations regularly for evidence of attacks by insects or disease.
Fertilization usually is not necessary for evergreens unless serious nutrient deficiencies exist. Hardwood (deciduous) trees sometimes benefit from fertilization. Fertility needs should be determined by soil test or foliar analysis.
To avoid damaging seedling roots, do not apply fertilizers directly in the planting holes.
