💡 The Finger Test Rule: Before watering your money plant, push your finger 1–2 inches (2.5–5 cm) into the soil. If it feels dry at that depth, it is time to water. If it still feels moist, wait another 2–3 days and check again. This simple test outperforms any fixed schedule.
💡 The 10% Volume Rule: A reliable method for money plants is to water with approximately 10% of the pot’s total volume per session. A 6-inch round pot holds roughly 1 quart (1 liter), so water with ~100 ml (3 fl oz). Always water until you see a little drainage from the bottom (if drainage holes are present), then empty the saucer after 30 minutes to prevent root rot.

Money Plants belong to the simplest species to grow in Water. Simply lay fresh cuttings in a glass full of pure Water, making sure that the knot stays underwater. The plant adapts soon and forms roots during some days.

Only the roots must stay underwater. That is a nice evergreen house vine that can grow in Water without special tools or experience.

How to Grow Money Plants in Water

The Money Plants known also as Pothos, rank among the best for indoors. They enjoy big popularity because of their ability to stay alive in Water, what makes them great for folks that want green decor without soil or trouble of care. One can grow them in simply pure Water or with hydroponics, without any addition of food.

Money Plants in Water really do not need feeding.

One uses healthy cuttings to spread new plants, whether in soil or in Water. Farming of Money Plants in Water is liked because of their nice looks and little need of attention. They show big flexibility and adapt to different vases according to the style of the rooms.

If you cut a stem and put it in a bottle full of Water with a bit of sugar, roots will appeer already after one week. Money Plants answer to Water or soil, even so mineral Water brings stronger growth.

Change the Water weekly is needed. Clean the glass well will stop the growth of algae. Here is the main issue for keeping Money Plants healthy in Water.

Act carefully with the amount of food, if you decide to add something. Quarter strength at every second change of Water is enough, when one does that twice a month. Too much minerals ore fluoride in the Water can harm the leaves and in the end kill the whole plant.

An interesting trick is to use plastic vases with holes in a pretty jar without drain. Pouring Water in the outer tin allows the inner jar to slowly absorb the right amount of Water. Even almost dead plants revive commonly within some weeks by means of this way.

Growing Money Plants in a plastic bottle, the leaves can fall over time. Moving the plant to glass vases helps it grow new leaves, even under the Water level. That is unusual, but genuinely happening.

The Chinese Money Plants, called Pilea peperomioides, differ from Pothos. They need Water when the soil feels dry, almost weekly during summer and every two weeks in winter. Roots of Pilea absorb and keep Water well, so they fail in cases that keep them too wet long.

A small jar helps better control the state of the plant, because soil dries more quickly. Lay small stones one inch deep in the bottom of the jar helps drainage and stops root rot. A plant with roots in soil, if moved directly inWater, probably will get root rot and will die.
