Tecoma Plant Problems

Tecoma is an attractive variety of flowering shrub that can bring an abundance of life and color to your outdoor spaces. Unfortunately, Tecoma isn’t immune to common outdoor pests and weather problems that afflict many other types of plants.

Aphids, caterpillars, and whiteflies can often be seen clinging to the foliage, while fungal diseases like powdery mildew usually require more intensive treatment.

Extreme heat can cause the plant’s leaves to curl and wilt, while prolonged exposure to cold temperatures can damage the roots. Proper management of your Tecoma will go a long way in keeping its health at optimal levels throughout the seasons.

Be sure to provide enough irrigation during dry periods, prune it regularly, fertilize once every two weeks, and either cover or treat it for any infestations it may face. With the right care, you’ll be rewarded with a vibrant show as Nature’s display of beauty for years to come.

Tecoma Plant Problems



Wilting leaves, yellowing of the leaves, fungal growth on the roots, drooping stems and branches, as well as an overall unhealthy appearance of the plant.


Poor drainage of the soil, too frequent watering and not allowing the soil to dry out between watering intervals, and overwatering due to incorrect calculation of water required by the plant.


Ensure that your Tecoma is planted in a well-draining soil mix; allow your Tecoma enough time to dry out between waterings (check if the soil is moist before adding more water); water plants thoroughly once a week to saturate the root zone; and take care not to apply too much water.

Be sure to keep track of how much you are watering your Tecoma so that you can adjust when necessary. Also, consider using fertilizer or mulch during periods of drought to help your Tecoma stay hydrated for longer periods.

Problem Description Solution
Yellowing leaves Leaves turning yellow and dropping off Check soil moisture and adjust watering, ensure proper drainage, and fertilize regularly
Powdery mildew Fungal disease causing a powdery white coating on leaves Prune affected leaves and increase air circulation, treat with fungicide if necessary
Root rot Fungal disease causing wilting and root decay Improve soil drainage and avoid overwatering, replant in fresh soil if necessary
Aphids Small insects that cluster on new growth, causing stunted growth and yellowing leaves Spray with insecticidal soap or neem oil, or introduce natural predators such as ladybugs
Caterpillars Larvae that chew on leaves and flowers, causing damage Handpick or use a natural pesticide such as Bacillus thuringiensis
Frost damage Exposure to frost causing browning and wilting of leaves and flowers Cover plants with frost cloth or move to a protected location
Nutrient deficiency Lack of essential nutrients causing stunted growth and yellowing leaves Fertilize with a balanced fertilizer according to manufacturer’s instructions

Poor Drainage

Symptoms of Poor Drainage in Tecoma Plants

The most common symptom of poor drainage in Tecoma plants is wilting or yellowing of foliage. Other signs include stunted growth, root rot, and leaf spots.

The leaves may become dry and brittle, or they may exhibit signs of nutrient deficiencies. If left untreated, the plant will eventually die.

Causes of Poor Drainage in Tecoma Plants

Poor drainage in Tecoma plants can be caused by heavy clay soil or compacted soil that prevents water from draining away properly. Over-watering or not allowing the soil to dry out between waterings can also be a factor.

Incorrect planting techniques such as burying the stem too deeply can lead to poor drainage and cause root rot.

Solutions for Poor Drainage in Tecoma Plants

To resolve poor drainage issues with Tecoma plants it’s important to fix the underlying cause before attempting to provide further care.

If the issue is heavy clay soil, consider amending it with compost or other organic materials to improve its ability to drain well.

Ensure that you are avoiding over-watering by checking the soil moisture with your fingers before applying more water.

Make sure that you are providing adequate spacing when planting so that roots have enough room to spread out properly without becoming overcrowded and impeding drainage.

Common Tecoma Pests and Diseases


Common tecoma pests and diseases include

  • Powdery mildew
  • Leaf spot
  • Root rot
  • Aphids
  • Mites
  • Whiteflies
  • Sap-sucking insects

Symptoms of these pests and diseases range from yellowing or discoloration of leaves to spotting or discoloration of flowers to wilting or drooping of foliage. In addition, infested plants may also experience stunted growth along with premature leaf drop.


Most tecoma pests and diseases are caused by environmental issues such as too much moisture or insufficient light exposure.

Other causes include damage from insects that suck the plant’s sap, over-fertilization, inadequate air circulation, and poor drainage conditions. In some cases, improper pruning can also lead to pests and diseases in a tecoma plant.


To prevent tecoma from being affected by pests and diseases, it is important to keep the plant’s environment free of excess moisture and well-ventilated with plenty of sunlight exposure. Avoid overcrowding your plants as this can lead to reduced air circulation which contributes to disease outbreaks.

Regular watering using a soaker hose can help reduce pest infestations while proper pruning techniques can help improve air circulation within the plant’s canopy and limit potential insect damage.

Insecticidal soaps or oil sprays are effective at controlling most insect pests while fungicides are available for treating fungal problems such as powdery mildew or leaf spot infections.

Common Tecoma Pests and Diseases

Lack of Light


Inadequate lighting can cause a Tecoma plant to become weak and spindly, with pale foliage and fewer blooms than normal. The leaves may also appear smaller than expected, or in some cases, the growth may be stunted altogether.


The main reason for inadequate lighting could be that the plant is located too far away from a window, or it’s not receiving enough direct sunlight throughout the day.

Other causes could include shading from an object nearby (such as other plants or trees) or too much artificial lighting in the area that’s preventing the Tecoma from absorbing all of the necessary light it needs to thrive.


To ensure your Tecoma gets enough light, start by positioning it closer to a window or other source of natural sunlight if possible; aim for at least 6 hours of direct sunlight every day during spring and summer months, while 4-5 hours should suffice in fall and winter.

Also make sure no objects are blocking the sunlight from reaching your plant (e.g., curtains, furniture, etc.).

If you need to supplement with artificial light sources such as grow lights, consider installing them on opposing sides of the room for more balanced coverage and ensure they are positioned about 12-14 inches away from the plant itself.

Prevention and Maintenance

Proper soil and watering techniques

These are essential parts of successful gardening, as the right soil and water ensure that plants are getting the correct nutrients they need to flourish.

Soil should be well-draining yet retain moisture to keep plants hydrated; this can be achieved by mixing organic matter such as compost into the soil.

Watering should be done regularly but not in excess, as this can lead to root rot or other issues.

Proper soil and watering techniques

Adequate lighting conditions

Adequate lighting conditions vary depending on the types of plants being grown and their natural environment.

As a general rule, plants will require six to eight hours of direct sunlight each day for them to thrive; however, some may prefer partial shade or full shade depending on their species.

Supplemental lighting such as grow lights may be necessary indoors or when an area is not receiving enough sunlight.

Regular pest and disease control

Regular pest and disease control measures should also be taken to maintain healthy plants. This includes checking your plants regularly for signs of pests or diseases, as well as applying suitable treatments if any are found.

Common pest treatment methods include insecticidal soaps, neem oil sprays, or traps; while for diseases copper-based fungicides may be used in prevention or treatment applications.

Regular pest and disease control

Proper pruning and grooming

Proper pruning and grooming are important steps to take when caring for garden plants to encourage healthy growth and flowering displays throughout the year.

Pruning involves selectively cutting away dead or unwanted branches from trees or shrubs to promote new growth; while grooming involves trimming off any overgrown branches or foliage that may be impacting other parts of the plant negatively (e.g., blocking light).


Overall, Tecoma plants have a variety of problems that can be difficult for gardeners and homeowners alike to handle. Although proper planting and fertility management can help prevent some of these problems, others such as powdery mildew may still occur.

Gardeners and homeowners will likely have to remain vigilant about watching for signs of Tecoma plant problems and take prompt preventive action if necessary. Resistant cultivars are also available that are less likely to succumb to pests or diseases than other plant varieties.

With the right knowledge, resources, and cared-for plants, Tecoma plants should be able to thrive in our gardens.
