When it comes to watering your plants, there are several options. You can use a watering can, which is the most efficient way to water large areas or indoor plants. If you have a small garden and want something that's easier than carrying around a heavy can, try using soaker hoses instead.
If you're looking for something more eco-friendly than plastic bottles or cans of water--which will eventually break down in landfills--you might consider investing in an automatic drip irrigation system (DIY kits start at under £50). These systems use less water than traditional sprinklers because they deliver small amounts at regular intervals instead of all at once; they also don't waste any excess liquid because each plant gets exactly what it needs based on its size and location within your yard or garden bed.
