Gardening: Avoid Common Seedling Mistakes in Early Sowing

Gardening guides highlight several frequent errors that can hinder seedling growth. Overwatering creates root rot and damping‑off disease; seedlings should be kept in moist but not soggy soil, preferably watered from below. Insufficient light causes plants to stretch thin and weak, a condition known as vergeilen; a bright south‑facing window or supplemental grow lights are recommended.

Sowing too early, especially for warm‑season vegetables such as tomatoes and cucumbers, leads to weak stems and poor establishment. Recommended sowing windows range from late February for early varieties to mid‑April for later crops. Using nutrient‑rich garden soil instead of a light, low‑fertiliser seed‑starting mix can suffocate roots; a specialized seedling substrate promotes healthy development. Planting seeds too densely limits access to light, water and nutrients, so spacing seeds according to label guidance is vital. Finally, planting depth must match seed size—large seeds a few centimeters deep, fine seeds barely covered—to ensure proper emergence.
