Common Grass Seed Buying Mistakes
Mistake 1: Choosing Based on Price Alone
Problem: Cheapest seed often means poor germination, weed seeds, or inappropriate varieties Solution: Consider cost per successfully established plant, not just cost per kilogram
Mistake 2: Ignoring Growing Conditions
Problem: Selecting sun-loving varieties for shady areas or vice versa Solution: Honestly assess your garden's light, soil, and water conditions
Mistake 3: Buying Too Much or Too Little
Problem: Waste from over-purchasing or project delays from under-purchasing Solution: Accurately measure areas and buy 10-20% extra for touch-ups
Mistake 4: Ignoring Seed Age
Problem: Old seed has reduced germination rates and vigor Solution: Check packaging dates and buy from reputable suppliers with good turnover
Mistake 5: Mixing Incompatible Varieties
Problem: Combining varieties with different growth rates or maintenance needs Solution: Use pre-mixed blends or consult experts for custom mixes
