How do I hold my peace lily alive? Among the plants and flowers sent to my family after my grandfather's...

Among the plants and flowers sent to my family after my grandfather's recent annihilation was a big peace lily within a pot. It's dying and we'd really like to gather it. We've tried watering it more, watering it less, we've tried more sunlight, smaller quantity sunlight. What are ideal conditions for a peace lily?
Is at hand math contained by a flower,...
Funeral plants are notoriously over planted (a big green flush for a week or so)I would call somebody names out starts(hand them out to family) and use fresh potting soil. Spathiphylum(Sp?) are pretty good house plants, they agree to you know when to water them by flagging(drooping)before things acquire critical, I've seen them used surrounded by Beta splendors vases, where on earth the vase is clear and holds a Siamese combat fish and a plant in the dampen as a sort of closed ecosystem.

Spiders surrounded by my mulch?

What generous of plants take home a dutiful...
Answers:    They should be pretty undemanding... here's the lowdown.

Assuming the plant is 1.5-2' tall, it should be getting 6-8 ounces (about a cup full) of water once per week. A bit smaller number if smaller a bit more if bigger.

Light - low to medium, mostly won't do direct sun.

Fertilzer - NO miracle grow or blue crap, use a good natural that doesn't have a brackish buildup.

IF the leaves are browing around the edge, mist the plant couple times a week might be dry nouns, (low humidity).

IF the leaves are soft and yellowing, probably too much water.

IF the leaves are browning from the center outward, too much sea or something toxic to it (ie cat pee, soda dumped in pot, something approaching that).

Chances are its going through shock as its probably changed environments recenetly (grower, shipper, florist, gift benefactor, then you). probably merely needs a bit of time.
