Most likely cause

Rot at the base. Do the opposite of watering: let it dry out fully, check the pot drains, and inspect the base for brown mush. This is why you always feel the mix before reacting to a droop.

What’s causing it

Thirst (dry potting mix)

How to tell

The soil is bone dry and the whole plant has gone limp. It perks back up within hours of a good drink, often with wrinkled heart leaves beforehand.

The fix

Water thoroughly (for a Sweetheart plant that’s usually every 11 to 17 days in summer), and the leaves should recover the same day.

Cold, wet roots

How to tell

It’s sitting near a cold window or an AC vent, and the soil is damp at the same time. The combination of cold and wet is what actually stresses this plant, not the cold alone.

The fix

Move it somewhere with steadier temperatures and let the soil dry fully before the next watering. Cold plus wet roots is what tips this plant into trouble.

Recently moved or repotted

How to tell

It started drooping right after a repot, purchase, or move. The disturbed, slow-to-recover roots on this plant can’t take up water properly for a while.

The fix

This is transplant shock. Keep it dry for a week or two rather than watering to ‘help it settle’: extra water on a stressed, slow-rooting plant like this does more harm than good.

Too much heat or sun

How to tell

It wilts in the heat of the afternoon but recovers by evening.

The fix

Shift it out of direct midday sun. A temporary wilt in heat is the plant conserving water.

A sudden change while budding

How to tell

Along with drooping foliage, unopened buds or flowers fall, usually a reaction to a sudden change in light, temperature, or watering right as Sweetheart plant was budding.

The fix

Keep its spot and watering completely stable through the bloom cycle. Once it settles, the next flush of buds should hold.

Prevention

Before watering, check that the pot drains freely and never sits in standing water. If the mix is still damp, wait and check again.
