Follow these steps to plant your window box:

Step Action
1 Remove plants from their pots and gently loosen the roots
2 Create a planting layout, ensuring plants have enough space to grow
3 Create a hole in the soil for each plant, slightly larger than the root ball
4 Place the plant in the hole, ensuring the base of the stem is level with the soil
5 Fill in around the plant with soil, pressing down gently to remove air pockets
6 Water thoroughly until the soil is evenly moist

Care for Your Window Box

Regular care will ensure your window box thrives:

  • Water consistently, allowing the top inch of soil to dry out between waterings
  • Fertilize monthly with a balanced, water-soluble fertilizer during the growing season
  • Prune plants as needed to maintain shape and encourage bushiness
  • Monitor for pests and diseases, treating promptly if necessary

With proper care, your window box will transform your window into a beautiful, living display. Enjoy the process and watch your green thumb grow!
