Frequently Asked Questions

Everything you need to know about growing a beautiful garden

The best time to plant vegetables depends on your climate zone. Generally, cool-season crops like lettuce and peas thrive in early spring, while warm-season crops like tomatoes and peppers should be planted after the last frost date.
Most gardens need about 1 inch of water per week, either from rainfall or irrigation. Water deeply but less frequently to encourage strong root growth. Early morning is the best time to water to minimize evaporation and disease.
Loamy soil with good drainage is ideal for most plants. It should be rich in organic matter, have a pH between 6.0-7.0, and retain moisture while allowing excess water to drain. Adding compost annually improves soil structure and fertility.
Companion planting, crop rotation, and encouraging beneficial insects are effective natural pest control methods. Marigolds deter many pests, while ladybugs and lacewings eat aphids. Regular inspection and hand-picking larger pests also helps.
