Choose the planting site carefully. Avoid low-lying areas in the landscape, as this is typically where frost settles, earning these areas the nickname “frost pockets.” The ideal site is downwind of large trees to protect the kiwi from heavy winds.
Clear all weeds and cover crops from the planting area.
Fix drainage problems by tilling the soil to a depth of 2 feet and amending the soil. Horticulturists with Oregon State University cite a New Zealand study in which it was determined that kiwi roots that spend as little as three days in soggy soil show severe damage. Add 3 to 6 inches of bark chunks or chunky compost, mixed into the top 6 to 12 inches of soil, to aerate it and help it drain quickly.
Dig the planting hole deep enough so that the kiwi's roots don't bend when planted. Remove the kiwi from its pot and place the roots in the hole. Fill the hole with soil. Attach the vine to the support structure.
Water the kiwi until the soil is damp to a depth of 6 inches, and keep it slightly moist until you notice new growth.
