Giant Sequoia Tree Care Guide

Provide young giant sequoia (Sequoiadendron giganteum) with sufficient light, water and fertilizer, and you will find caring for the most massive tree species in existence is surprisingly trouble-free.

Planting the Tree: When your tree is a few feet tall, you may want to transplant it to a permanent location in the landscape. Early spring and early fall are especially good times for transplanting.

Light: Give the Sequoia tree full-sun exposure but don’t worry if its current location is in light afternoon shade. If it receives heavy shade any time of day, however,  try to allow more sunlight to filter to the tree or move it to a sunnier location. 

Water: Water giant sequoia's regularly so that the ground is constantly moist but never saturated. Within the dripline, apply about 10 gallons of water for each inch of a diameter that is measured on the trunk at your knee height. Garden hoses supply 10 gallons of water about every five minutes.

Temperature: If the weather in your region is severely hot or cold, you'll need to pay special attention to your tree — especially when it's small. Do not let your seedling burn in extreme heat, nor freeze in harsh, cold weather. Generally speaking, keep your tree indoors during times of freezing and sub-freezing temperatures. In the spring, after your last freeze, place the tree outdoors once again in a sunny location.
