🌱

Layering

Pin the stem down with a stake or stone to keep it in firm contact with the soil.

  1. 1
    Bend a flexible stem down to the soil without detaching it from the parent plant
  2. 2
    Nick the bark where it touches the ground and cover that spot with soil
  3. 3
    Keep moist until roots form, then sever from the parent plant

Division

Choose suckers that already have roots for a higher success rate.

  1. 1
    Locate root suckers emerging around the parent plant
  2. 2
    Dig around the sucker, keeping some roots intact
  3. 3
    Transplant immediately to its permanent spot and water well

What Diseases Commonly Affect Trumpet Vine?

TLDR: Trumpet Vine is susceptible to 6 known diseases. Monitor regularly for early detection.

Powdery Mildew

Medium

Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.

Aphids

Medium

Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.

View solution

Root Rot

High

Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.

View solution

Scale Insects

Medium

Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
