Cordyline Australis Red Sensation

Outdoors: Place in full sun (6-8 hours) to part sun (4-6 hours). Indoors: Bright south-facing exposure in indirect light.

Keep the soil moist consistently (but not soggy).

Add a gravel tray, spritz daily, use a humidifier or group with other plants.

This plant loves heat and humidity so the warmer the better. Keep away from heating vents or direct sunlight though as the leaves could burn.

Outdoors in full (6-8 hours) to part sun (4-6 hours), where nights are above 62°F.

A slow release fertilizer or diluted liquid fertilizer can be applied to the soil surface on the exterior or interior of this plant. Refrain from fertilizing during the winter. If the foliage exhibits tip burn, back off on the feeding as it can have exude salts from their leaf tips.

Indoors: 

When the plant is rootbound or there is dieback on its growth, then it's ready to repot (early spring before growth starts), plant in a 2" bigger container in diameter and slightly deeper than the existing planter. 

Use an indoor container mix that is well-draining. Add soil to the bottom to elevate the root ball. 

Lift the plant and inspect the root ball. Notice if there are any dead or rotting roots and trim off with sterile pruners. If the plant is rootbound, cut through the roots to alleviate continued encircling. Trim up the side of the root ball so new roots will form. 

Ensure the plant is sitting about 1" below the edge of the pot to avoid water spillage. 

Add more soil and backfill around the sides by tamping down. Do not cover the current level of soil on the plant but add soil up to this level. 

Water thoroughly, leaving the soil damp but not soggy. Add more soil after watering if the soil settles.

Outdoors: 

Before planting or repotting in a container, water the plant in the grower pot well. 

Find a spot in the garden where there are at least 4-8 hours of direct sunlight each day. 

Be generous by digging a hole twice the pot's width and 1 inch shorter than the grower pot to raise it above the soil level for good drainage. 

Use a pitchfork or a sharp object to stab the soil walls to make several indentions for the roots to take hold. 

Tickle the roots to loosen them if they wrap inside the container.

Place the plant in the center of the hole. 

Fill the hole with water first, so the roots get another good drink.

Next, backfill with native soil mixed with compost by one third to one half (if the native soil is clay). 

Add a rooting hormone fertilizer to this backfill mixture. Tamp the soil firmly down around the edges and mound up. Avoid covering the original soil level of the plant that was in the container. 

Add mulch as needed but not next to the stem or branches of the plant. 

Water lightly. Continue to observe the soil moisture each day, depending on the temperatures and soil drainage. Keep consistently moist.

Keep yellowing or browning fronds cut off. If tips get burned, trim off the edges at an angle so it looks more natural. Keep the soil clean and replenish with soil if depleted.

that's well-draining. You may mix in a rooting hormone into the soil to help establish root growth. Fill the container with soil to an inch at the top. Very lightly scrape off small portions of the brownish covering of the epidermis on the stem to expose the green cortex. Stick the branch in the pot and add more soil if needed. Give the plant a drink and let drain. Keep the soil consistently moist to promote the roots to grow from the stem. Keep it in part-shade or bright, indirect light to get it established. Check after 8-10 weeks to see if the roots are getting established by gently pulling upward on the stem. If it is snug, then you have success! Keep the soil moist continually, and don't let it ever dry out completely.
