Conifers are attractive additions to any garden landscape because of their year-round greenery. They're also attractive to gardeners and landscapers who need low-maintenance trees. Conifers require little care after initial planting, so if you understand a few simple rules, you can be an excellent grower of conifers.
Know when to plant conifers. The best time to plant conifers is in the spring or early autumn. Conifers do best when planted during periods of cooler temperatures and higher rainfall. If possible, choose an overcast day to plant a conifer so the tree won't lose as much water.
Dig a hole twice as wide as the root ball, but more shallow, allowing the root ball to stick up slightly from the ground.
Loosen the root ball before planting by tapping the side of the pot with your hand.
Water the conifer as soil dries out for two weeks after planting. After that, conifers rarely need water except during extremely dry periods.
Mulch around the conifer's base with 5 to 7.5 cm (2 to 3) inches of mulch. Do not allow the mulch to touch the tree's trunk.
Fertilise annually with a balanced, all-purpose garden fertiliser. For best results, fertilise in early spring or late autumn.
Prune dead branches of the conifer as soon as possible to prevent possible spread of disease or infestation. Conifers are not capable of regenerating growth from old wood, so avoid pruning more than a third of the length of a branch at one time.
Conifers rarely wilt, but instead will lighten in color if they need water. They may also turn brown on the inside of the tree. If in need of water, water conifers slowly and abundantly, allowing the water to penetrate deep into the soil. A full, deep watering is better than frequent watering.
Stake the conifer for the first year after planting if it's in a windy location.
