It can be difficult to water hanging plants due to their location, so you may need a step ladder or stool to get up to the height required. A long-neck watering can is often the best option, such as this watering can with a removable long sprout at Amazon, while alternative ways for watering hanging baskets include getting self-watering baskets or using drip irrigation. When watering hanging plants there can be wastage from watering draining out of the bottom, so consider using something to catch that excess water in the vein of self-watering baskets that catch it in their reservoir.
