Yellow dot is a fast, trailing groundcover that spreads into a dense mat of glossy, lobed green leaves dotted with small yellow daisies from spring to fall. It grows in full sun, part shade or shade, which makes it useful for covering ground where many desert plants struggle.

It needs moderate water, and frost can knock it to the ground in winter, though it grows back in spring. It spreads quickly and roots where its stems touch soil, so keep it edged and away from open desert areas.

Best for: covering ground fast in sun or shade, raised planters, large patio pots, and green groundcover beds that get regular water.

Where it works best in Arizona yards
Fast green groundcover
Fills in within a season
↓

Yellow dot spreads quickly into a dense mat about 1 to 2 feet tall and 6 to 10 feet wide. Plant it 4 to 6 feet apart to cover a bed fast. Small yellow daisies dot the leaves from spring to fall.

Sun or shade
Covers the shady side too
↓

It grows in full sun, part shade or shade, so it can cover the ground under a tree or on the north side of the house. It keeps its leaves through a mild winter.

Raised planters and large pots
Spills over the edge
↓

It works well in raised planters and large patio pots, where its trailing stems spill over the sides. A pot also keeps its spread under control.

Where it struggles
Frost and spreading
↓

Frost can kill it to the ground, though it usually grows back in spring. It spreads fast and roots where stems touch the soil, and it is listed as invasive in parts of the United States. Keep it edged and out of open desert areas.

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

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
About once a week
↓

Water it about once a week, and more often in summer heat. It survives short dry spells, but regular water keeps it thick and green. Let the top of the soil dry a little between waterings.

Frost
Cut back in early spring
↓

Frost can kill it to the ground in winter. It usually grows back quickly as the weather warms. Trim off the frost-damaged growth in early spring.

Keeping it in bounds
Trim edges often
↓

It spreads fast and roots wherever its stems touch soil. Trim the edges often and cut it back hard to thin it. Pull stems that root outside the bed.

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.

Soil guide: tap any type for details
Sandy soil
Ideal
Sandy soil that drains well suits it best.
Sand dries out faster, so check it more often in summer.
Native desert soil
Manageable
It grows in most soils, including alkaline soil, if water drains away.
Give it regular water, since it is not a dry-desert plant.
Clay
Manageable
It tolerates clay if drainage is good.
Water that stands in clay can rot the roots.
Pots and raised planters
Well suited
It trails nicely over the edge of large pots and planters.
A pot keeps its spread under control.
Caliche
Prep required
A caliche layer traps water around the roots.
Break through it when you dig so the planting hole drains.

Is yellow dot invasive?
It can be if it is not kept in check. It spreads fast, roots where its stems touch soil, and is listed as invasive in parts of the United States. Edge the bed, trim it back often and keep it out of open desert areas.

How fast does yellow dot spread?
It grows fast into a mat about 1 to 2 feet tall and 6 to 10 feet wide. Plant it 4 to 6 feet apart to cover a bed in a season.

Does yellow dot grow in shade?
Yes. It grows in full sun, part shade or shade, so you can use it under trees and on shady sides of the house.

How often should I water yellow dot?
Water it about once a week, and more often in summer heat. It survives short dry spells, but it looks best with regular water in soil that drains.

Will frost kill yellow dot?
Frost can kill it to the ground, but it usually grows back quickly in spring. Trim off the frost damage in early spring once new growth starts.

How do I keep yellow dot in bounds?
Trim the edges often and cut it back hard when it gets too thick. Pull up stems that root where you do not want them.

Can I grow yellow dot in a pot?
Yes. It works well in large patio pots and raised planters, where the stems trail over the edge. A pot also keeps it from spreading.

When does yellow dot bloom?
It blooms from spring through fall with small yellow daisy flowers. Keep it watered through summer to keep the flowers coming.

How far apart should I plant yellow dot?
Plant it about 4 to 6 feet apart. Use 4 feet when you want the ground covered quickly.

What soil does yellow dot need?
It prefers sandy soil that drains well and tolerates clay if water does not stand. Avoid low spots that stay soggy.

Can yellow dot irritate skin or allergies?
Yes. The leaves and stems can irritate skin, so wear gloves when you trim it. Its pollen can also bother people with allergies.

Can I plant yellow dot near a pool?
Yes. It drops very little litter, so it works in beds near a pool.
