Micro Crested Blue Myrtle is a crested blue myrtle cactus that local growers sell as a micro crested form. Its blue-gray growth spreads sideways into folded, wavy crests rather than climbing into columns. Crested plants build slowly over many years. This is a collector's plant for a patio pot, a raised planter or a spot near the door. It needs little water once rooted.

Best for: a collector's patio pot, a raised planter by the entry, and close-up spots where the folded texture shows.

Where it works best in Arizona yards
Collector's patio pot
Texture up close
↓

Crested growth folds back and forth on itself, so the plant looks best where you can see it up close. A patio pot or a table-height planter shows it off.

Raised planters
Stays low and slow
↓

Crested plants build slowly over many years, so it keeps its shape in a raised planter or entry bed for a long time.

Keeping it crested
Trim normal growth
↓

Now and then a normal round stem pushes out of a crest. Cut it off at its base so it does not take over the crested growth.

Where it struggles
Wet soil, frost, young sun
↓

Soil that stays wet causes rot, especially in pots without drainage. Frost near 25 to 30°F can scar it, and young plants can sunburn in hard sun.

Needs may vary based on your yard layout, desired density, sun and shade, and any underground wiring or piping.

How many plants fit in your bed or planting area?
These are general guidelines. Conditions vary by soil type, sun, and time of year.
For this plant: Keep it in fast-draining soil or cactus mix and let it dry fully between waterings. Shade it lightly while young. Trim off any round, normal stems. Cover it on nights near freezing.

Ideal The easiest time to plant. Roots get the longest stretch of good weather to settle in.
Good Plantable with normal care. Roots settle in more slowly, but there is little stress.
Extra care needed Can be done with closer attention to watering while the plant settles in.
Most demanding The hardest window. Planting is possible, but expect frequent deep watering while it settles in.
This month Outlined in the strip.
This plant can go in the ground any time of year. The colors show how much effort getting it rooted takes in each month.
In the Valley, frost is possible from about Thanksgiving to Valentine's Day.
When to plant around Sedona, Cottonwood and Globe
Not a good fit for mid elevation areas. See the plant check above for why.
When to plant around Prescott, Payson and Chino Valley
Not a good fit for the high desert. See the plant check above for why.
When to plant around Flagstaff, Show Low and Williams
Not a good fit for the mountains. See the plant check above for why.
Watering a new plant
Wait, then every other week
↓

Wait about a week after planting before the first water. Then water every other week while nights stay above 60°F. In cooler weather, water only after two to four weeks without rain.

Watering once rooted
Deep and occasional
↓

Water deeply in the warm months only when the soil is dry, and give little or none in winter. Plants in pots dry out faster and need water more often than plants in the ground.

First summer sun
Prevent sunburn
↓

Plant it with the same side facing the sun as in the nursery. Cover a new plant with light shade cloth its first summer, then remove it.

Frost nights
Protect below about 25 to 30°F
↓

Below about 25 to 30°F, frost can scar the stem tips. Cover the tips with foam cups or frost cloth that reaches the ground, not plastic. Take covers off in the morning.

Keeping the crest
Cut off normal stems
↓

Now and then a normal, round stem sprouts from the plant. Cut it off at its base so the plant puts its energy into the crest.

Site and soil prep
Drainage test, weed cloth, rock and decomposed granite yards
↓

Drainage test first. Dig the hole and fill it with water. If water is still sitting in the hole a day later, you likely hit caliche, clay or hard soil, so fix the drainage before planting. If it drains very fast, the soil is sandy. Standing water around roots is a common reason new plants fail.

Weed cloth. Cut it away from the planting hole and where the roots will spread. Remove any plastic sheeting completely, since it keeps water and air out of the soil.

Rock or decomposed granite with no soil underneath. Bring in soil close in texture to your native soil, mix it with the soil below, and build up enough depth for roots before planting.

Caliche prep
Break through or mound over it
↓

If you can break through. Use a breaker bar, pick, or jackhammer. Dig through the caliche and break out the solid chunks. Backfill with the soil you dug out, with no compost or manure in the hole. Confirm drainage before planting.

If you cannot break through. Dig narrow holes through the hard layer beside the root ball, not under it, and refill them with the same soil, not gravel. If it still will not drain, plant on a low mound of the same soil.

Planting
Root ball, depth, emitter placement
↓

Root ball. Check the outside edges for any roots circling around. Loosen or cut those so they grow outward. Do not break up the center of the root ball.

Depth. The top of the root ball should sit at or just slightly above the surrounding soil level. Planting too deep can lead to rot and kill the plant.

Drip emitters. At planting, put the emitters on the root ball, on different sides of the plant. After about 2 months, move them to the outer edge of the root ball. Over the first year, add emitters farther out toward the edge of the branches as roots grow. Once a plant is rooted, never water only at the trunk.

Ideal
Drains fast, which is what this cactus needs
Backfill with the same native soil, no rich amendments

Holds water around the roots and leads to rot
Loosen the planting area with coarse sand or pumice

Prep required
Water cannot drain through a tight caliche layer
Dig through it so the planting hole drains

Use a fast-draining mix of sand, grit and gravel
Pots dry faster, so check the soil more often in summer
Have a question?
Ask us anything about this plant and we will get back to you directly.

What does micro crested mean?
It is the name local growers use for this crested form of blue myrtle cactus. Like other crested plants, it grows in folded crests instead of round columns.

How is it different from the regular Crested Blue Myrtle?
Both are crested forms of the same cactus. This one is sold as the micro crested form. Ask us to see current plants before you choose.

How big will it get?
Crested forms of blue myrtle grow slowly and stay far smaller than the regular cactus. Plan on a pot or planter plant, not a tall column.

Why is a normal stem growing from my crest?
Crests are unstable, and normal growth can return. Cut the round stem off at its base, or it can take over the crest.

How often should I water it?
Let the soil dry out completely, then soak it. Water more in summer and very little in winter. Always use a pot with a drainage hole.

Does it need full sun?
Give it light shade while young and full sun as it matures. Keep the same side facing the sun when you plant or repot.

How cold can it take?
It can be scarred by frost near 25 to 30°F. Cover it on those nights with frost cloth that reaches the ground, or move a potted plant under cover.

Does it have spines?
Yes, it has short spines. Handle it carefully, with gloves or folded newspaper, when you repot it.

Micro crested cactus for Phoenix patios

This crested blue myrtle grows in folded crests instead of columns. It suits a patio pot or raised planter where you can see its texture up close.

How crested cacti grow

In a crested plant the growing tip spreads into a line, so the stem folds into wavy fans. Crested plants grow slowly and stay much smaller than the regular form.

Keeping a crest from reverting

Normal round stems sometimes grow out of a crest. Cut them off so the plant stays fully crested.

Watering a crested cactus in a pot

Soak the pot, then let the mix dry completely before watering again. Water more in summer and very little in winter.

Frost care for micro crested blue myrtle

Protect it on nights below about 25 to 30°F. Frost cloth that reaches the ground works best.
