Environmental Stress
First, let’s take a look at what’s happening around your plant. Sometimes, the problem isn’t the plant itself—it’s what’s going on in its environment. Could something be stressing it out?
Here are a few questions to help you figure out if environmental stress is the culprit behind your plant’s struggles:
1. Has there been a sudden cold snap?
Signs: Blackened, mushy leaves (frost damage).
Solution: Cover plants with frost cloth or bring potted plants indoors when cold weather is expected.
2. Is it too hot?
Signs: Wilting, crispy edges, scorched or faded leaves.
Solution: Water deeply in the morning, add mulch, and provide temporary shade for delicate plants.
3. Is wind damaging plants?
Signs: Torn leaves, plants leaning to one side, dry soil.
Solution: Use stakes, plant windbreaks (like shrubs), or move potted plants to a more sheltered spot.
4. Are plants getting the right amount of sunlight?
Too little: Pale, leggy growth.
Too much: Bleached or sunburnt leaves.
Solution: Adjust placement—shade plants that scorch easily, and move light-starved plants to a sunnier spot.

Water Issues
Watering seems simple—until your plant starts looking sad, and you’re left wondering if you gave it too much or not enough. Too dry? Too soggy? Somewhere in between? Water problems are one of the most common reasons plants struggle, but the good news is, they’re also one of the easiest to fix.
Here are some key questions to help you determine if watering issues are to blame for your plant’s troubles.
1. Is the soil too wet?
Signs: Yellow leaves, moldy soil, mushy roots (root rot).
Solution: Improve drainage, avoid overwatering, and use well-draining soil.
2. Is the soil too dry?
Signs: Wilting, crispy brown edges, slow growth.
Solution: Water deeply and consistently—check soil moisture before watering.
3. Does water drain properly, or is it pooling?
Standing water can drown roots and invite disease.
Solution: Amend soil with organic matter or raised beds for better drainage.

Soil Health & Nutrients
Your soil is more than just dirt—it’s your plant’s entire support system. If something’s off beneath the surface, your plant will let you know, often with yellowing leaves, stunted growth, or weak stems. Poor soil or a lack of nutrients could be the hidden reason your plant isn’t thriving.
Here are some key questions to help you determine if soil health or nutrient deficiencies are behind your plant’s struggles.
1. Is the soil compacted and hard?
Signs: Stunted growth, difficulty absorbing water.
Solution: Loosen soil with a garden fork and mix in compost.
2. Have you tested the soil pH?
Signs: Yellowing leaves, nutrient deficiencies.
Solution: Test with a soil kit—adjust pH with lime (to raise) or sulfur (to lower) as needed.
3. Do plants need fertilizer, or have they had too much?
Deficiency: Yellowing leaves, weak growth.
Over-fertilization: Brown leaf edges, burned spots.
Solution: Use a balanced fertilizer sparingly and follow plant-specific needs.
4. Is the soil lacking organic matter?
Healthy soil supports plant growth!
Solution: Add compost or well-rotted manure to improve fertility.
Pests & Diseases
Sometimes, the problem isn’t your watering or soil—it’s something sneaky lurking in your garden. Pests and diseases can wreak havoc on plants, often showing up as chewed leaves, strange spots, or sudden wilting. The tricky part? They’re not always easy to spot at first.
Here are some key questions to help you figure out if unwanted visitors or plant illnesses are to blame for your plant’s struggles.
1. Are there holes or chew marks on leaves?
Common pests: Caterpillars, beetles, slugs.
Solution: Hand-pick pests, use natural deterrents like neem oil, or introduce beneficial insects.
2. Are leaves sticky or covered in black soot?
Likely pests: Aphids, mealybugs, or scale insects.
Solution: Spray plants with insecticidal soap or use a strong stream of water to wash them off.
3. Do plants have spots, powdery coating, or odd discoloration?
Likely disease: Fungal, bacterial, or viral infections.
Solution: Remove affected leaves, improve air circulation, and avoid overhead watering.
4. Are plant roots healthy or rotting?
Signs: Brown, mushy roots (root rot).
Solution: Reduce watering, ensure proper drainage, and use well-aerated soil.

Plant-Specific Needs
Not all plants play by the same rules. What works for one might be completely wrong for another. Some thrive in full sun, while others prefer shade. Some love rich, moist soil, while others need it dry and well-draining. If your plant isn’t happy, it might just not be getting what it personally needs.
Here are some key questions to help you determine if your plant’s struggles come down to its unique requirements.
1. Is this plant suited for my climate zone?
Some plants can’t handle extreme temperatures.
Solution: Check plant tags or research what grows best in your area.

2. Is this plant in the right soil type?
Some need sandy soil, others thrive in clay or loam.
Solution: Amend soil if necessary—cactus and succulents need fast-draining soil, while vegetables like rich, loamy soil.
3. Do plants need support, pruning, or staking?
Tall or vining plants may fall over.
Solution: Use cages, stakes, or trellises as needed.
4. Are companion plants helping or competing?
Some plants thrive together, while others compete for nutrients.
Solution: Research companion planting to avoid conflicts.
