Diagnosing the Problem

1. Watering Issues


For example, these marigolds are like well-drained soil hence they are sensitive to waterlogging which leads to root rot. This can be as simple as feeling, touching the soil, and testing it with your finger to see if it is still damp about one inch down. To know whether the plant is receiving too much water, it is also important to check the texture of the soil; if it feels soggy it’s time to reduce the water being supplied to the plant.


It is important not to let the soil become saturated with water before air-drying between waterings. First of all, the pot or the garden bed chosen should have the right drainage system. If conditions permit it and the soil in which the plant was placed is compacted, it is recommended to transplant the plant into a drainage mix or loosen and enrich the garden soil with sand or perlite.

But more often to water the plant, saturating it to the root zone, not on the foliage. It is advised to mulch the base of the plant for him to maintain as much soil moisture as possible.

2. Nutrient Deficiency

It is not very demanding in terms of fertilizers, but it does need fertilizing to have appropriate nutrition. Calcium deficiency may result in white, brown, or black leaves, wilting, yellowing, or turning red and stunted growth.


This entails applying a slow-release fertilizer with a 10-10-10 NPK ratio on the plants every four to six weeks during that growing period. Or, a liquid one can be applied at a weak concentration every two weeks, for example, and the application can be easily administered as the liquid fertilizer is liquid. Do not apply too many fertilizers as this will compound the salt accumulation problem and worsen the plant’s conditions.

3. Pests and Diseases

Aphids and Spider Mites:

These little creatures are capable of inflicting severe losses by sapping the green matter of plants, thus stunting, and causing the leaves to turn yellow.


Examine the plant for signs of pests such as honeydew setae or tiny webs could be observed. Scrape off aphids with a FORCEP hose them off with water or spray with insecticidal soap. Organic pest management can be applied in the control of spider mites, and this can be done either by using neem oil or miticides.

To incorporate meaning into growth, promote air movement around the plant and do not water it overhead. The fungicides can be used on baits as a last measure under the recommended instructions of manufacturers.

Root Rot:

Affecting both the stem and foliage of plants, root rot occurs due to overwatering or having soils with poor drainage, featured by brown and slimy roots as well as slow development.


If root rot is a serious possibility then the plant should be transplanted out of the pot and the roots should be pruned back. Prune the stalks back to maintain the plant’s size and transplant them into a new potting mix that has good drainage. Water only occasionally because the foliage must be allowed to recover to support new healthy growth from the roots.

4. Environmental Stress

Excessive Heat or Cold:

Marigolds prefer warm climates mostly but these are not good when exposed to very hot conditions or when the climate is freezing.
