🔍 Possible Causes (8)
Aphids
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.

Boron Deficiency
Boron deficiency is a nutrient disorder that affects plant growth and development, particularly at growing points. Boron is essential for cell wall formation, reproductive development, and carbohydrate transport. While critical for plant health, boron has a narrow range between deficiency and toxicity, requiring careful management.

Calcium Deficiency
Calcium deficiency is a common plant disorder caused by insufficient bioavailable calcium in the growing medium or, more frequently, by low transpiration rates that prevent proper calcium transport to new growth. It manifests as necrotic leaf margins, curling of young leaves, stunted growth, and in severe cases, conditions like blossom end rot in fruits. The disorder primarily affects rapidly growing tissues where calcium demand is highest.

Phosphorus Deficiency
Phosphorus deficiency is a common nutritional problem that hinders healthy plant growth. Phosphorus is essential for root development, flowering, fruiting, and energy metabolism. When deficient, plants exhibit stunted growth and leaves with purple or reddish coloration, especially on older leaves.

Downy Mildew
Downy mildew is a fungal-like disease caused by oomycetes (water molds) that thrives in cool, wet conditions. It affects a wide range of plants, causing yellowing leaves with fuzzy white-gray growth underneath, leading to defoliation and reduced yields if left untreated.

- • Stunted growth in severe cases
⚡ Quick Fixes:
Remove and destroy all infected plant parts. For severe infections, remove entire plant.
Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.

Caterpillars
Caterpillars are the larval stage of moths and butterflies that feed voraciously on plant foliage, stems, flowers, and fruits. Common species include cabbage loopers, tomato hornworms, armyworms, and cutworms. These pests can cause extensive damage by consuming large amounts of plant tissue in a short time. They vary in size from small (1/4 inch) to large (5 inches), with colors ranging from green to brown, often featuring stripes or spots. Caterpillars are highly mobile and can quickly spread throughout gardens, making them one of the most destructive common pests.

Root Rot
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.
