How to Water String of Pearls Plants

String of pearls are drought-tolerant and only require irrigation when the soil around the roots have completely dried out. Typically , watering each 14 days can be sufficient for string of pearls to satisfy their requirements for moisture and not cause root rot, but the frequency of watering will vary depending on the conditions.

Making sure that the watering is just right is essential when taking care of string of pearls since they are prone to root rot that is caused by excessive irrigation and slow drainage of soils.

String of pearls also have different water requirements at different seasons because of their summer period of dormancy.

The proper watering regimen must be used combined with well-draining soil and the proper pots to support a healthy string of pearls plant.

How Often to Water String of Pearls Plants

String of pearls plants are succulents with special adaptations for growing in dry and hot desert conditions. Their leaves are designed to look like pearls, allowing for the highest the water storage capacity of each leaf and reduce the area of the loss of water.

Since string of pearls favor dry conditions , they are vulnerable to issues that result from excessive watering.

To produce pearl strings with success, it is essential to mimic the conditions for watering in their natural environment by giving them in the correct quantity.

String of pearls plants must only be watered after the soil has dried completely. Usually, this means that the string of pearls need to be watered each 14 days.

The time required for the soil to dry can differ based on:

  • Temperature and humidity in your environment.
  • The pot’s size as well as the hanging container.
  • The pearls are in an air flow caused by air conditioning, forced air, or close to an energy source.
  • The rate at which the soil drains the soil.

The most effective method to determine the proper frequency of watering for the string of pearls plant in accordance with your specific environment, is to touch the soil in the base of the container via the drainage hole and check if it’s wet or dry.

If the soil is moist then you may leave the watering for a day or two however if it feels dry, this is the ideal time to water your the string of pearls.

This is a perfect representation of the conditions of moisture that the pearl string has been adjusted, making sure that the plant has access to water, while the soil is able to dry out around the roots to prevent root decay.

String of pearls can also enter a state of dormancy during the summer months (as an approach to deal with high temperatures and drought) and then actively grow throughout the year.

This means that the plant has less need for water in the summer months and is more susceptible to root rot as a result of excessive irrigation.

Your pearl string should be sprayed with water at least once every three weeks during the summer months at maximum.

A good indicator of whether the pearls plant needs watering is when the pearls begin to shrink after dehydration. If your pearls are green but beginning to shrink it is a sign to water them.

How to Tell if you are Watering too Often…

If you’re watering your the pearls of your string more than every week, it’s likely that you are overwatering even in dry climates.

The signs of excessive watering are pearls turning yellow or translucent and translucent. At this point, you need to reduce the amount of watering and allow the soil completely dry so that your plant can recuperate.

String of pearls are extremely sensitive to excessive watering (particularly in the summer months when it is dormant) but under-watering is easily remediated, therefore always allow your soil’s drying out between watering sessions.

A string that is well-watered pearls must be healthy, green and solid pearls that indicate that the plant has the appropriate amount of water to meet its needs.

Correct Method for Watering String of Pearls

While your climate will determine the frequency of watering your pearl string, the watering method remains the same regardless of your climate.

Make sure to water your plants with plenty of water, so that the excess water seeps out of the bottom in the container.

This will ensure it is penetrated the soil, allowing it to reach the roots.

If you water your plants too light, only the top inch of so of the soil is wet and the roots aren’t capable of absorbing the water they require, causing the pearls to shrink and possibly change color as an indication of drought stress.

(Succulents often shrivel because of excessive watering, as well as under watering. Check out my article on how to recognize the distinction).

The practice of watering generously, and allowing for the soil to dry between intervals of watering, mimics the conditions for watering of the string of pearls’ natural environment . It is followed by a massive down torrent of rain, and a time of drought.

Top Tips for Watering String of Pearls

  • Always make sure to water the base of the plants. The watering of the pearls from above will increase the humidity of the micro-climate , and reduces the transpiration (water removal) of the leaf. This is the primary method of the plant to regulate the balance of the water within its pearls.
  • Make sure to water your pearl string early in the morning. The morning watering will allow the plant to utilize the water efficiently, whereas the stomata on succulents shut down at night, which restricts the ability of pearls to shed excess moisture their leaves, so they are able to keep the proper level of water.
  • The practice of watering at night while the plant is in dormancy is a sign that the roots sit in wet soil for a long time, which increases the chance of root decay.
  • Reduce the frequency of watering in summer. Although it might seem counterintuitive to cut down on watering during Summer the string of pearls go dormant during the hottest times of the year to provide a strategy to save water during times of high temperatures and drought therefore it needs less frequent irrigation.
  • A generous amount of water, but not often enough, promotes healthy root growth, whereas water that is not soaked completely deprives your string of water pearls and excessive watering can increase the chance of root decay.

The Plant String of Pearls are placed in Pots with drainage holes in the Base

String of pearls plants are prone to excessive moisture around the roots, so it is vital that the pot includes a drainage hole at the base that allows the excess water to drain after the watering.

Then, water until you can get a little bit of water draining from the bottom of the pot is one of the best methods to make sure you’ve watered your plant with an sufficient amount of water.

If you place string of pearls in pots that do not drain, then the water will pool around the root of your plant, which causes the pearls to become transparent or yellow and could result in the plants to turn brown or rot.

It is important to note that sometimes, excess water may still clog the root of your pearl string despite the drainage holes in your pots because of:

  • Roots that block the drainage hole. If you purchased your pearl string as an established plant and you notice it drains slowly, examine the drainage hole to determine if there are roots that have grown in the drains and slow down the speed of water drainage.
  • Use of saucers and tray beneath pots. A lot of people put containers and saucers underneath pots that have drainage holes to stop water from spilling into their homes. It is essential to clean the saucer frequently to ensure that the amount of water been absorbed is less as it can keep your soil too wet.
  • decorative outer pots. When plants with string of pearls are offered in shops, they are usually planted in plastic pots with drainage holes , and an attractive pot with drainage holes that have similar effects to saucers or trays that have standing water. Make sure that water is able to escape easily to ensure that your string of pearls remain healthy.

Well Draining Potting Mix is Critical When Watering String of Pearls

To make your string of pearls to success and to ensure they stay alive, it is essential that they are placed in the correct pots of soil.

String of pearl plants will not thrive in standard compost or potting soil because they retain too much moisture around the roots for a prolonged period of time, which causes the pearls to turn transparent or yellow and creates the conditions that cause root decay.

String of pearls develop naturally in extremely sandy, gritty soil that drains quickly after irrigation and doesn’t retain moisture.

It is crucial that you recreate soil and conditions of the native environment before potting your pearl string.

There are special succulents and cactus potting dirt (available at garden centers as well as on Amazon) that contain more inorganic materials (stones, grit , and sand) to aid in promoting drainage and replicate the characteristics of soil in the native string of pearls habitat.

The correct soil can help keep the ideal moisture balance for your pearl string to reduce the risk of excessive watering, and ensure that your plant is healthy.

Key Takeaways

  • String of Pearls are drought-resistant plants that require watering with an adequate soak once each 14 days. Make sure that your soil have completely dried before you water again. Do not water more than three times per week during the summer dormancy. to prevent root decay.
  • String of pearls need a potter’s soil that is similar to the soil that drains well in their natural habitat to allow excess water to drain from the root.
  • String of pearls can be planted in pots that have drainage holes at the base so that water can drain instead of accumulating around the roots, which causes root rot.
  • The sign of an over-watered string of pearls are pearls that change color, or become soft and translucent in appearance. Pearls that are not hydrated become brown and shriveled. A healthy string of pearls plant is one with green pearls that are hard and hydrated. Make sure the soil is dried before irrigation.
