A peace lily grows best in bright, indirect light and a draining pot, with water added when the upper mix begins to dry. Keep the root ball lightly moist rather than saturated, and empty the saucer after watering. The plant can tolerate a dim corner, but stronger filtered light usually produces better growth and a better chance of flowers.

Understand what you are growing
Peace lilies belong to Spathiphyllum, a group of tropical foliage plants. Their white sail is a modified leaf called a spathe; the small flowers sit on the central spike. A spathe often becomes green as it ages, so green flowers are not automatically evidence of disease. Cultivars differ substantially in mature size. A small desk plant and a large floor specimen need the same general approach but different amounts of space and water.
Choose a plant with firm stems, several healthy leaves and no unpleasant smell from the pot. A few tired flowers are less concerning than a soft crown. Remove decorative wrapping that blocks drainage, and find the actual nursery pot inside the outer container.
Choose light by observing the leaves
An east-facing window or a position protected from strong afternoon sun is a useful starting point. Window direction alone does not determine light: trees, neighboring buildings, curtains and distance from the glass all matter. Direct summer sun can leave bleached or brown patches, while a distant shelf can keep a plant alive without supporting vigorous growth.
Move a poorly lit plant closer to a suitable window gradually rather than placing it abruptly in hot sun. Compare new growth over several weeks. Existing burned patches will not turn green again. Dust broad leaves with a soft damp cloth, supporting each leaf underneath so its stalk is not bent. Leaf-shine products are unnecessary.
Water before repeated dramatic wilting
Check the upper inch of mix with a finger and lift the pot to learn its weight. When the surface begins to dry but the root ball has not become a hard, dry block, water slowly across the surface until excess drains out. Allow the container to drain completely before returning it to a decorative cover.
A wilted plant in dry mix often needs water. A wilted plant in wet mix needs investigation, not another drink. Check drainage, recent watering and root condition. Repeated collapse followed by rescue watering stresses the plant even if it seems to recover quickly. The interval changes with light, temperature, pot size and season; a fixed weekly dose cannot account for all four.
Use an airy mix and a modest pot
A commercial indoor potting mix that holds moisture while draining freely is a reasonable base. Avoid dense garden soil indoors. Repot when roots densely fill the container, watering becomes difficult, or the mix has broken down. Move up only one practical pot size. A large amount of unused wet mix can stay saturated after the rooted portion has used its water.
Set the crown at approximately its previous depth and work fresh mix around the sides without burying leaf bases. Drainage holes are essential. Stones in the bottom do not substitute for holes and reduce usable rooting space. If the plant is healthy and not crowded, leave it alone rather than repotting on a rigid annual schedule.
Encourage flowers without forcing fertilizer
Healthy foliage is the first goal. Improve inadequate light before trying to stimulate flowers with more fertilizer. Commercially produced plants may have been treated to flower for sale, so a purchased display does not guarantee continuous flowering in a home. Mature plants can bloom again under suitable conditions, but their schedule varies.
During active growth, use a houseplant fertilizer at its labeled rate and interval; reduce or pause feeding when growth slows. More fertilizer is not a shortcut to blooms and can contribute to brown tips or salt accumulation. Cut a fully faded flower stalk near its base with clean scissors, taking care not to cut the adjacent leaf stalks. Leave healthy leaves to support the plant.
Read brown tips and yellow leaves in context
One aging lower leaf may yellow naturally. Several yellow leaves, persistently wet soil and declining growth point toward a root-zone problem. Brown edges can follow drought, salt buildup, harsh sun or low humidity. These symptoms overlap, so avoid buying a treatment based on the color alone.
Write down the last watering and inspect the underside of leaves for pests. If the soil smells sour or the plant stays limp while wet, gently inspect roots. Firm pale roots are different from mushy, collapsing tissue. Remove badly rotted material with clean tools and correct the drainage problem. A severely damaged crown may not recover. Trim only dead leaf tissue for appearance, leaving a narrow brown edge rather than cutting deeply into healthy green tissue.
A practical first-month routine
For the first week, choose one suitable location and learn how quickly the pot dries. Check it every few days without automatically watering. Keep it away from heating vents, cold drafts and glass that becomes very cold at night. After two weeks, compare a photograph of the whole plant with the original rather than judging a single leaf each morning.
If new growth looks healthy, keep the routine steady. If conditions are clearly wrong, change the most likely cause and note the date. Changing light, pot, fertilizer and watering simultaneously makes it hard to identify what helped. Divide a crowded clump only when each division can retain useful roots and leaves; division is optional, not a requirement for flowering.
Household safety and placement
Peace lilies contain insoluble calcium oxalate crystals and should be kept away from children and animals that chew plants. They are not true lilies, but that distinction does not make them edible. If a person or pet chews the plant, seek advice from the appropriate poison service or veterinarian instead of trying a home remedy.
Place a large specimen on a stable surface with a waterproof saucer that will not damage furniture. Keep foliage out of busy walkways and check that a decorative pot can be lifted safely when wet. The useful measure of success is firm new foliage and a root ball that cycles between watering and gentle drying, not a plant that remains constantly soaked.
A useful product example
Product example: the Fiskars Softouch Micro-Tip Pruning Snip is a small cutting tool to consider for removing faded flower stalks. It is not needed for ordinary watering, and a clean sharp pair of household scissors can handle the same light work. Check the exact model, blade style and lock before purchasing; never use a tool on the plant immediately after cutting diseased material without cleaning it.
