Beginner Gardening: Watering Your Plants Effectively

Watering your plants may seem simple, but bad habits can hinder their growth. Too much or too little water, wrong timing, incorrect method... Here's a guide to watering your plants properly and keeping them in top condition.

Understanding Your Plants' Needs

Not all plants have the same water requirements. Before watering, consider:

• Plant type: Cacti and succulents need very little water, while tropical plants and vegetables require regular watering.
• Sun exposure: A plant in full sun dries out faster than one in shade.
• Soil type: Sandy soil retains less water than clay soil.
• Planting type: Soil in the ground dries out more slowly than in pots.

Tip: Insert your finger 2-3 cm into the soil. If it's dry, it's time to water.

Special Cases Requiring Extra Attention

• Potted plants dry out faster than those in the ground, especially if exposed to sun or wind. Check the compost moisture regularly, as water evaporates more quickly in containers. In summer, some plants may need almost daily watering. Also note that compost dries faster in terracotta pots, as this porous material allows water evaporation through its walls, unlike plastic which is non-porous and retains more moisture.
• Seedlings need slightly moist soil to germinate properly, but without excess water that could cause rot. Use a spray bottle to water gently and avoid dislodging them.
• Newly planted plants haven't yet developed deep roots, making them more vulnerable to water shortage. Water them more frequently for the first few weeks until they establish. Once well-rooted, you can space out watering.

When to Water?

The time of day matters to avoid waste and promote water absorption by roots.

• Morning: The best time, as water has time to soak in before evaporation from sunlight.
• Evening: Also a good option, especially in summer, but avoid excess moisture in winter to limit disease risks.
• Midday: Avoid, as water evaporates too quickly and can even burn leaves exposed to sun.

Watering Also Depends on Season.

How Much Water to Use?

It's better to water less frequently but deeply rather than small amounts too often.

• Generous watering allows water to reach deep roots.
• Space out watering to avoid excess moisture causing root rot.
• Adjust seasonally: More water in summer, less in winter.

Tip: If water runs off without soaking in, do a light initial watering, wait a few minutes, then water again.

How to Water Effectively?

• Water at plant base to prevent water pooling on leaves, which encourages disease.
• Use the right tools:
  • A watering can with rose attachment for seedlings and young plants.
  • A hose or drip system for gardens.
  • A spray bottle for humidity-loving houseplants (orchids, ferns).
• Mulch the soil: Apply mulch (straw, bark, grass clippings) around plants to retain moisture and reduce watering frequency.

Good to know: Mosquitoes breed in stagnant water without predators to control them. This includes water reserves, abandoned buckets or saucers under pots. Remember to empty them to prevent proliferation!

Water-Saving Tips

• Collect rainwater for natural, economical watering.
• Use self-watering pots to limit evaporation.
• Group plants by water needs to optimise watering.
