🚨 Serious Problems (5)
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.
Symptoms:
Wilting leaves despite moist soil • Yellowing or browning of leaves • Stunted growth and poor vigor
⚡ Quick Fixes:
Emergency unpotting: Remove plant immediately from wet soil. Speed is critical....
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Symptoms:
Pale discoloration spots on leaves • Fine silk webbing covering leaves and stems • Tiny yellow or white speckles on leaf surface (stippling)
⚡ Quick Fixes:
Step 1: Immediately spray all affected plants with rubbing alcohol (70% isopropyl) diluted 1:1 with water...
Fusarium Wilt
Fusarium wilt is a serious fungal disease caused by the soil-borne fungus Fusarium oxysporum. The fungus invades roots and blocks the water-conducting vessels (xylem) of the plant, causing progressive wilting and eventual death. Host-specific forms of the pathogen exist that attack different plant species.
Symptoms:
Wilting during the hottest part of the day with recovery at night (early stage) • Asymmetrical yellowing of leaves (one side of plant or leaflets) • Progressive upward wilting from the stem base
⚡ Quick Fixes:
Remove Plant: Immediately remove entire infected plant with roots. Dispose in sealed trash (DO NOT compost)....
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Symptoms:
White cottony masses on leaves, stems, or fruit • Small pink or white soft-bodied insects (1/20 to 1/5 inch) • Sticky honeydew secretions on plant surfaces
⚡ Quick Fixes:
Step 1: Immediately spray visible mealybugs with 70% isopropyl alcohol for instant kill on contact...
Southern Blight
Southern blight is a devastating soilborne fungal disease caused by Athelia rolfsii (formerly Sclerotium rolfsii), affecting over 500 plant species including vegetables, ornamentals, and fruit crops. The fungus survives in soil through resting structures called sclerotia that resemble mustard seeds and can remain viable for years.
Symptoms:
Brown to black lesions on stem near soil line • Water-soaked appearance on lower leaves • Sudden and permanent wilting of entire plant within days
⚡ Quick Fixes:
Step 1: Remove infected plants IMMEDIATELY with roots and soil...
