About Aptos Blue Redwood

Sequoia sempervirens 'Aptos Blue' · also called Aptos Blue Redwood, Aptos Blue Coast Redwood · flowering

Aptos Blue Redwood is a selected cultivar of Coast Redwood prized for its intensely blue-green, drooping foliage and vigorous upright form. Faster-growing than many redwood cultivars, it makes a striking specimen or tall screen tree in mild climates. The pendulous branchlets and blue-toned needles set it apart from the standard species.

Mature size: 15–30 m tall (50–100 ft) in cultivation, spread 4–6 m (13–20 ft); can be larger in ideal coastal sites

Watch for — Summer leaf scorch on new growth: Young pendulous shoot tips may scorch in intense reflected heat or persistent dry winds. Water deeply and site away from heat-reflecting walls in hot inland gardens.

Indoor size vs how big it gets in the wild

Aptos Blue Redwood is a tree at heart. Indoors a pot and your ceiling keep it to 15–30 m tall (50–100 ft) in cultivation, spread 4–6 m (13–20 ft), but in the ground it is a different scale of plant entirely (can be larger in ideal coastal sites). Indoors and in a pot, expect 15–30 m tall (50–100 ft) in cultivation, spread 4–6 m (13–20 ft). In the ground with no restriction it is a completely different plant — can be larger in ideal coastal sites — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Aptos Blue Redwood is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: apply a slow-release acidifying conifer fertiliser in early spring. young trees benefit from annual feeding for the first 3–5 years to support rapid establishment. mature trees in fertile soil need little additional nutrition.

How to keep aptos blue redwood smaller

You are not stuck with the maximum size. For aptos blue redwood specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: aptos blue redwood can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want aptos blue redwood and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow aptos blue redwood bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for aptos blue redwood the accelerators are:

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

Light is almost always the ceiling. The aptos blue redwood light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When aptos blue redwood outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for aptos blue redwood:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the aptos blue redwood repotting guide. If you want more of this plant instead of a bigger one, the aptos blue redwood propagation guide turns prunings into new plants.

Aptos Blue Redwood size — frequently asked questions

How big does aptos blue redwood get?

Aptos Blue Redwood reaches 15–30 m tall (50–100 ft) in cultivation, spread 4–6 m (13–20 ft) when grown indoors, and far larger where it grows unrestricted (can be larger in ideal coastal sites). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is aptos blue redwood slow or fast growing?

Aptos Blue Redwood is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Aptos Blue Redwood is a tree at heart. Indoors a pot and your ceiling keep it to 15–30 m tall (50–100 ft) in cultivation, spread 4–6 m (13–20 ft), but in the ground it is a different scale of plant entirely (can be larger in ideal coastal sites).

How long does aptos blue redwood take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
