Going away for a week doesn't mean your urban garden has to suffer. With some simple preparation, you can ensure your planter boxes stay perfectly hydrated. The best method is to set up a passive self-watering system before you leave.
For a reliable DIY solution, try wick irrigation. Place a large water reservoir, like a jug or bucket, slightly above your planter boxes. Insert one end of a cotton rope or a specially designed watering wick deep into the soil near the plant's roots, and place the other end in the water reservoir. Capillary action will draw water steadily to the soil as it dries out. This method is excellent for most container plants.
Alternatively, create a slow-drip system using recycled plastic bottles. Poke small holes in the cap of a clean bottle, fill it with water, and quickly invert it into the soil. The water will seep out slowly. For larger planters, use a wine bottle filled with water and inserted neck-down into the soil.
For less hassle, consider commercial options like self-watering planters with built-in reservoirs or terracotta watering spikes that attach to standard bottles. These provide consistent moisture with minimal setup.
Before you depart, give your plants a thorough deep watering. Move planter boxes out of direct, intense sunlight to a spot with bright, indirect light to reduce water evaporation. A light layer of mulch on the soil surface can also help retain moisture. With these smart strategies, you can return to vibrant, healthy plants after your week away.
