Succulents are easier to grow than most, but like all plants, they have their problems, too. Here are some troubleshooting tips for common afflictions and conditions from the author of Succulents Simplified.

SYMPTOM Bleached, beige, or dark patches on leaves
CAUSE Excessive sun exposure
REMEDY Move plants into bright shade. Remove damaged leaves if unsightly.

SYMPTOM Distorted buds that don’t open, tiny insects on new growth
CAUSE Aphids or thrips
REMEDY Spray with isopropyl alcohol diluted half-and-half with water and improve air circulation.

SYMPTOM Cancerous growth on aloes
CAUSE Aloe mite
REMEDY Cut out the damaged tissue, clean your tools, and if the plant is potted, isolate it from other aloes.

SYMPTOM Distorted growth at leaf axils and centers of rosettes, cottony bits
CAUSE Mealybug
REMEDY Remove or isolate affected plants; spray with diluted isopropyl alcohol and improve air circulation.

SYMPTOM Cottony bits adhering to roots
CAUSE Root mealybug
REMEDY Discard the affected soil; wash the container in soapy water; take cuttings of the plant and repot in fresh soil.

SYMPTOM Black depressions in aloe leaves
CAUSE Bacterial leaf spot
REMEDY Apply cinnamon spray or commercial systemic per label directions.

A graptopetalum already damaged by ahil has become colonized by mealybugs. When an infestation is this extensive, it’s best to discard the plant.

SYMPTOM Webs and paprika-like dots on leaves
CAUSE Red spider mite
REMEDY Spray with diluted isopropyl alcohol and improve air circulation.

SYMPTOM Sickly look, brown bumps on stems
CAUSE Scale insects
REMEDY Remove or isolate affected plants, spray with diluted isopropyl alcohol, scrape the scale off stems with a plastic knife, wash the plant with mild liquid detergent, and repot it in fresh soil.

SYMPTOM Collapsed outer leaves, upright center (agaves)
CAUSE Agave snout weevil
REMEDY Dig up and destroy the affected plant. Do not replant agaves in or near that area. Treat nearby agaves and soil with systemic insecticide.

SYMPTOM Holes in leaves
CAUSE Snails and slugs
REMEDY Hand pick; release predator snails or apply iron phosphate (Sluggo).

SYMPTOM Garden plants cropped to ground level
CAUSE Deer, squirrels, rabbits, or javelinas
REMEDY Enclose young, tender plants in chicken-wire cages.

SYMPTOM Collapsed, putty-colored leaves
REMEDY Tent in-ground plants with frost cloth until the temperature exceeds 32 degrees F. Move containers beneath shelter or indoors. Prune dead tissue.

A type of mite that affects aloes makes tissues distorted and bubbly looking, with an orange tinge.

SYMPTOM Squishy stem or trunk
CAUSE Overwatering
REMEDY Take cuttings from healthy tissue and replant. Discard the old soil with the plant.

SYMPTOM Loss of sheen, shriveling at tips
CAUSE Underwatering
REMEDY Water thoroughly and then keep soil about as moist as a wrung-out sponge.

SYMPTOM Elongated, stretched-looking stems and leaves; flattened or downward-curving rosettes
CAUSE Not enough light
REMEDY Give greater sun incrementally. Rotate container weekly for even exposure.

SYMPTOM Greening of yellow, red, or orange leaves
CAUSE Too much pampering
REMEDY Stress the plant with less water, more sun, and less rich soil. Don’t fertilize.

SYMPTOM Irregular white rings on dark leaves
CAUSE Mineral deposits from evaporated water drops
REMEDY Using distilled water, gently wipe the leaves. Avoid splashing the leaves when watering the plant.

SYMPTOM Dry leaves at base of echeverias, aloes, or other rosette succulents
CAUSE Normal growth
REMEDY Crisp, papery leaves shade and insulate the stem. But if you find them unsightly, peel them away.

SYMPTOM Stem awkwardly long with rosette at the tip
CAUSE Normal growth
REMEDY Remove any old, dry leaves at the base of the rosette, then cut the stem 1 inch below healthy leaves and replant the rosette as a cutting.

SYMPTOM Closed or shrunken rosettes
CAUSE Heat, drought, or cold; dormancy
REMEDY Move container-grown plants under an eve or overhang to protect from harsh outdoor conditions. If plants are merely dormant, leave them alone; they’ll revive when they awaken.
