Watering

Water is the #1 growth factor after sunlight. But most garden failures come from the wrong watering habits, not too little water. The rule of thumb: water deeply, less often, and at the root – not on the leaves.

When to water

  • Early morning (6–9 AM) is best – leaves dry before the sun hits, roots drink all day.
  • Evening (after sunset) works too, but wet leaves overnight invite fungal disease.
  • NEVER water at midday in full sun – up to 50% evaporates before reaching the roots.
  • Finger test: push your finger 3–5 cm into the soil. Dry? Water. Damp? Wait.
  • Weather matters: rain of under 5 mm doesn't reach the root zone – you still have to water.

    • Shallow vs. deep watering

    Light daily watering

    Deep watering 2–3× per week

    Watering methods

    Watering can

    Classic, cheap, gives you control. Slow method, but good for small beds. Aim at the soil, not the leaves.

    Drip irrigation

    Porous hoses or drippers deliver water right at the root. Uses 50–70 % less water than sprinklers. Best for raised beds; combine with a timer.

    Ollas (clay pots)

    Unglazed clay pots buried in the bed, filled with water. Moisture seeps out slowly. Great for vacation coverage (1 refill lasts 3–5 days).

    Sprinkler

    Good for lawns, not ideal for vegetables – wets leaves, loses water to wind/evaporation. Only use for young seedlings and germinating beds.

    Save water

  • Mulch! 5–10 cm of straw/grass clippings halves evaporation.
  • Collect rainwater in barrels from your gutters – plants prefer it over chlorinated tap water.
  • Loosen the topsoil after every watering – breaks capillary channels that wick moisture out.
  • Group plants by water needs – heavy drinkers together, light drinkers together.
  • Water at the base only. Avoid sprinkling from above.

    • Water needs by category

    Different plants need different amounts of water. Match your watering to the plant:

    High (heavy feeders, fruit-bearing)

    Tomato, pepper, cucumber, zucchini, pumpkin, corn, celery: water deeply 2–3× per week, more in hot spells. Avoid wet foliage.

    Medium (root veg, leafy greens)

    Carrot, beet, lettuce, cabbage, broccoli, kohlrabi, spinach: keep soil evenly moist – especially important during head/root formation.

    Low (Mediterranean herbs, N-fixers)

    Thyme, rosemary, sage, lavender, beans, peas: tolerate drought well. Overwatering causes root rot. Water only when the top 5 cm is dry.

    Quick check: the finger test beats every timer. If the soil feels damp 3–5 cm down, wait another day. Your plants will thank you with deeper roots.
