Hi Mathias. Planting windowboxes is so much fun. It provides a mini garden right outside your window. If you include some scented flowers, wafts of fragrance will fill the room. Planting the windowbox requires broken pots or clay chards, multipurpose soil mix, plants and a watering can. First, windowboxes need good drainage if they are to do well; place a layer of broken pots (or even small rocks) in the base of the windowbox. This prevents the soil mix from becoming waterlogged. Half-fill the box with moistened soil mix and firm it down. Remove the plants from their containers. Loosen the root balls of the plants without damaging the roots. Plant them closely, but leave some space between each plant. Continue to plant, putting them where ever you want. Usually tall ones in the middle, shorter ones on the outside. Fill in holes with planting soil, especially between the plants. Water thoroughly when done, letting the excess water run out the bottom. Fill in any sunken areas with soil mix. Remember to water, fertilize and deadhead regularly. Some fun ideas are:
Christmas boxes: fill boxes with fake holly, mini trees, and garlands for the holiday season.
Shade boxes: fill with impatiens, lobelia, coleus, or begonias.
Sunny boxes: any bright annuals that catch your eye making sure to add hanging plants.
Herb boxes: plant oregano, parsley, thyme, lemon grass and any other herbs you like.
Have fun!
