Frequently Asked Questions
The five most common garden pests are aphids, cabbage worms, slugs, tomato hornworms, and flea beetles. Aphids affect nearly every vegetable and are easy to spot in clusters on new growth. Cabbage worms target all brassicas (broccoli, kale, cabbage). Slugs attack leafy greens, especially in moist conditions. Tomato hornworms can strip tomato plants overnight. Flea beetles create tiny holes in leaves of seedlings across many crops. Regular weekly inspection is the best defense against all of them.
Integrated Pest Management for Home Gardens
Integrated Pest Management (IPM) is the approach used by agricultural extension services and organic farms worldwide. It prioritizes prevention first, then monitoring, then the least-toxic intervention. In practice, that means building healthy soil (the foundation of pest resistance), choosing resistant varieties, rotating crops yearly, encouraging beneficial insects, and only reaching for sprays as a last resort. Most home garden pest problems can be solved with hand-picking, row covers, and companion planting before any product is needed.
Quick Tips for Staying Pest-Free
- Inspect your garden at least twice a week, checking leaf undersides, stems, and the soil surface around plant bases.
- Water at the base of plants in the morning. Overhead watering in the evening creates the damp conditions that slugs, fungal diseases, and many pests prefer.
- Rotate crop families on a 3 to 4 year cycle. Planting tomatoes in the same spot every year lets soil-borne pests and diseases build up to damaging levels.
- Encourage beneficial insects by planting a border of flowers like alyssum, yarrow, fennel, and dill. Ladybugs, lacewings, and parasitic wasps are your best allies against aphids, caterpillars, and whiteflies.
- Use the companion planting checker to find pest-repelling plant combinations, and the watering calculator to avoid the overwatering that leads to root rot and fungal problems.
