How To Care for String of Tears (Senecio Herreianus)

String of Tears care is a fairly simple process.

Below are a few things you need to know about String of Tears (Senecio Herreianus) care.

Sun Exposure & Light Requirements

String of Tears plants will grow best when they are grown in partial shade or indirect bright light.

Senecio herreianus plants will grow best in areas where they are not experiencing strong direct sunlight, so they should be grown under a tree or bush when grown outdoors.

String of Tears plants can also grow well indoors as long as there is some indirect light.

They can be placed in an east or south-facing window and should receive at least six hours of indirect light each day.

Watering Requirements

The String of Tears plants need to be watered once a week or every two weeks.

This Senecio plant should only be watered when the soil is dry.

The best way to check if String of Tears needs to be watered is by feeling the soil.

If it feels moist, then String of Teardrops don’t need water yet, but if it doesn’t feel moist and you can easily poke a finger into the dirt about an inch, it needs watering.

String of Teardrops doesn’t tolerate being overwatered, meaning you should never leave water sitting in their pot for extended periods.

Soil Requirements

String of Tears care starts with the correct type of soil.

String of Tears prefers a very well-draining, sandy, or loamy soil rich in organic material.

String of Tears does not like soils with high levels of clay. String of tears plants should not be grown in very heavy, poorly drained soils as they are prone to root rot.

A cactus/succulent soil mix is perfect for String of Tears plants.

Temperature and Humidity

String of Tears plants need a temperature range between 18 and 24 degrees Celsius (64.°F – 75.°F).

These plants are very susceptible to frost, so String of Tears should be protected from cold temperatures.

The String of Tears plants have average humidity requirements, which should be kept at around 50%.

Fertilizing

String of Tears plants should be fertilized once a year, preferably during the summer months.

Apply a weak solution of balanced, water-soluble fertilizer diluted to half strength.

Avoid over-fertilizing String of Tears plants as they can become too soft and lose their shape.

String of Tears plants are not heavy feeders, and they will thrive on a much less frequent feeding schedule.

Potting and Repotting

String of Tears plants are usually used as ground covers.

They can be grown in containers, but they grow best when planted into the soil with good drainage.

String of Tears plants need to be planted in a pot that is deep enough for the plant’s roots and not too narrow.

They are susceptible to root rot, so it is important to use drainage holes or gravel at the bottom of your container.

Senecio herreianus do well when grown with other low-water tolerant species like succulents, sedums, and sempervivum if they’re only watered minimally during hot months.

String of Tears plants require repotting every two to three years. You’ll know String of Tears is ready for a new pot when the roots start to come through the bottom of the current one.

Senecio herreianus plants should be transplanted during the fall or winter months.

The String of Tears can also grow as a hanging plant. They thrive in hanging baskets if they are given support to cling onto, like string or wire.

Pruning

String of Teardrops care requires trimming every now and then for more air circulation around the String of Tear’s foliage, which reduces humidity buildup around the String plant’s center leaf layer.

They should be trimmed back to the point where new String leaves start growing.

String plants can suffer from over-trimming, but under-trimming will cause a String plant to grow too tall for its pot and topple over in just a few months.

Make sure not to cut off healthy String leaves when pruning String of Tears.

Trimming String plants will increase the amount of String plant flowers next season because fewer String leaf sheaths are available to support flower buds, which is when they form.

The best time to trim String of Tears is September through October, before new growth starts coming out for the year after their dormant period has ended (generally in December).

Pests and Diseases

Although String of Tears plants are usually pest-free when properly cared for. The following pests can attack String of Teardrops:

  • Whitefly
  • Spider Mite
  • Mealybug
  • Aphids
  • Scale Insects

String of Tears plants can also develop the following diseases:

  • Fungal Disease
  • Verticillium Wilt
  • Botrytis Blight.

String of Teardrops are susceptible to several types of fungal infections, including powdery mildew and rust.

These pathogens usually infect Senecio herreianus during periods when the plant is under stress or not receiving proper care.

String of Tears plants grown under these conditions and not treated with fungicides can be affected by rust for the duration of their lives.

Senecio herreianus may also develop a fungus called Botrytis Blight, which is considered a very serious disease.

The best way to avoid String of Tears plant diseases is by providing String of Teardrops with ample light, good air circulation, and high humidity.

String of Tears plants that are grown under these conditions will be more resistant to disease development than those String of Tears plants not cared for properly.

How to Care for String of Tears (Senecio Herreianus) in Winter

String of Tears (Senecio herreianus) winter care is not very complicated. Still, it is important to note that String of Tears plants are frost-sensitive and need protection from the cold.

String for Teardrops care continues by checking on your plant every day to see if it needs water and to keep an eye out for pests.

How To Propagate Senecio Herreianus (String of Tears)

String of Tears is a succulent plant that can be propagated through stem cuttings or leaf cuttings.

Stem Cutting

String of Tears can be propagated through stem cutting.

Take a Senecio herreianus plant that has just flowered and let it dry for about two weeks to kill the sap. Then, cut off about a six-inch (15cm) piece below where the flowers were located on the stem before they bloomed.

Put this in the soil so it sticks out from beneath the surface but not too high above ground level. Cover with soil or an organic mulch like peat moss, straw, or hay until completely buried.

This will promote rooting at its base as long as there are no weed seeds in your propagation area shortly after planting.

String of Tears plants grow best when planted outdoors during springtime using their natural environment into consideration.

If you live in a colder region, String of Tears plants should be planted in the fall or winter months so they can get enough time to establish their roots before it starts getting cold and dry out again.

Leaf Cuttings

String of Tears can also be propagated through leaf cuttings.

Take String of Tears leaves that have been thoroughly dried and cut off a healthy one-inch (25mm) section.

Put it in a pot of soil with the cut end facing upwards and cover it with a bit of soil. Keep the soil moist to promote rooting.

Do not place String of Tears in direct sunlight, or they will dry out. Place String of Tears where it can be watered easily and receives indirect light.

The Senecio herreianus leaf will soon sprout roots, and String of Tears will be ready to be transplanted.
