Jade Plant Sunburn: Signs, Red Edges and How to Recover
Updated
Why does my Jade plant have sunburn?
Sunburn on a jade plant shows as pale, bleached patches that turn tan or brown and dry, usually on the most exposed leaves soon after a move into stronger sun. Red leaf edges in bright light are normal and not a burn. The burned tissue will not recover, but the plant usually does.
What to do first
Move the plant back a step from the strongest sun and check the mix is not bone-dry. Then reintroduce bright light gradually over several weeks. Leave burned leaves until they drop or trim them for looks.
Jade is a sun plant, which makes a scorched jade confusing. It is usually not the amount of sun but how suddenly the plant got it. Clemson Extension says jade does best with four or more hours of direct sun a day (Clemson HGIC 1507). The trouble starts when a plant used to dim light goes straight into that sun.
Is it sunburn?
Iowa State University Extension describes sun damage on succulents as brown or tan patches on leaves or stems, especially on interior leaves or new growth (Iowa State: succulent problems). University of Maryland Extension describes the early stage: pale, bleached or faded areas that later turn brown and brittle (UMD: excess light).
Signs that point to sunburn:
- Damage appeared within days of a move to a sunnier window or outdoors.
- Patches sit on the side facing the light, or on the most exposed leaves.
- The patches are dry and flat, not soft or raised.
- The mix may also have been dry. UMD says symptoms are more severe when strong sun combines with dry soil.
Rule out the look-alikes
| What you see | What it is |
|---|---|
| Red or purplish leaf margins in bright light, leaf firm and glossy | Normal color. NC State says the margins acquire a red tint in direct sun |
| Small raised blisters on leaf undersides that turn corky | Edema; see our jade edema guide |
| White dots or crust that wipe off | Mineral salts; see our mineral deposits guide |
| Soft, mushy, yellow leaves and stems in wet mix | Overwatering and rot (Iowa State) |
| Leaves dull, speckled or dusty-looking | Spider mites (Clemson) |
| Wrinkled, shriveled leaves with dry mix | Underwatering (Iowa State) |
Colored cultivars need a second look. Clemson notes ‘Sunset’ leaves are edged in gold and ‘California Red Tip’ edges turn purplish-red in bright light to full sun (NC State: Crassula ovata lists several red-tinted cultivars too). Bright color on a firm leaf is a sun response, not damage.
Why it happens
Iowa State says the main cause of sun scald is a succulent kept in low light for a while, then suddenly moved into bright or direct sun. The University of Maine warns that sudden increases in light, such as moving a plant outdoors into full sun, can damage even sun-loving plants (UMaine: Bulletin 2612).
Common triggers for jade:
- Moving it outside for summer straight into full sun.
- Moving it from a dim room to a south-facing sill.
- A new plant from a shaded nursery going into your sunniest spot.
- Hot afternoon sun through glass. NC State suggests a sunny spot that also gets some afternoon shade.
What to do
- Pull the plant back a step. Move it a little further from the glass, or into morning sun, while you acclimate it.
- Check the mix. If it is dry well below the surface, water thoroughly and let it drain. Clemson says to keep jade moist but not wet in spring and summer.
- Leave the damaged leaves. Iowa State says burned areas will not recover and leaves with sun scald usually drop. Stems callus over and keep a scar. Trim leaves for looks only once they are mostly dead.
- Acclimate gradually. UMD suggests starting with about 2 hours of direct sun a day outdoors, then increasing slowly. Iowa State advises changing light levels over several weeks.
- Do not overcorrect. A jade kept in dim light grows thin and stretched. Our jade light requirements guide explains how much sun to aim for.
Recovery
Judge recovery by new growth. Firm, glossy new leaves, perhaps with red edges, mean the plant has adjusted. Scarred older leaves will stay marked until they fall.
