Growing Spider Plants in Water Only:
Many people wonder if spider plants can live and grow in water alone. Although some people my argue with me, in my experience, the answer is yes. Growing spider plants in water alone works.
That said, I have not grown a full-size plant in water. The longest time I have left a spiderette in a glass of water has been about 4 months.
I don’t know if a full-grown plant could survive in water for a year, for example. Most likely, they would need a source of nutrients, especially before shooting off spider plant babies..
I usually transplant plantlets into soil before then so they don’t overtake my kitchen counter. However, if I don’t get around to transplanting for several months, the plants seem to be quite happy in water.
I don’t even add fertilizer. But adding fertilizer to spider plants doesn’t hurt.
Spider Plant Watering Tips:
You don’t have to worry about any “special requirements” for watering spider plants because they are so forgiving. You can forget to water these low maintenance plants – or even overwater them and they will usually survive and do just fine.
That said, for optimal growth and happy plants, follow these guidelines and tips:
1. How Often Should You Water Spider Plants?
Generally, I water my plants once a week. However, some people say that you can even extend that period up to 2 weeks. Spider plants don’t mind having their soil dry out completely between waterings.
Many people say that, as a rule of thumb, you should water your plant if the top inch of soil feels dry to the touch. How often will depend on how dry the surrounding environment is. For example, houseplants typically need more frequent irrigation than their outdoor counterparts.
2. Signs You are Overwatering or Underwatering Your Plants
When spider plants need more water, they will start to droop. This signifies that you should give them a drink. On the other hand, if the leaves yellow or form black tips, this can mean that the plant needs less water.
Tip: Even though these easy-going plants can grow fine without a self-draining pot, they do prefer drainage. Some people even like to water their plants over the sink, so they can give them plenty of fresh water and let the excess drain out thoroughly.
3. Irrigation Needs Change with the Seasons
The Farmer’s Almanac recommends watering your spider plants often enough to keep the soil moist during the summertime. In the winter months, you can cut back on the watering.
4. What Type of Water Do Spider Plants Like?
Although filtered water is better, regular tap water can work fine. That said, Joy Us Garden says that if you have water with a high salt content, consider using distilled water instead. This will keep your spider plant healthier and prevent brown leaf tips.
