Grow Petunia axillaris, aka wild white petunia, or cascading Wave or Surfinia petunias if you want a bushy plant.

Tips On Box Plant Care

1.Effective drainage is crucial. You can choose plant boxes with drainage holes already in them or drill your own. Overly moist soil can cause root rot, so avoid it at all costs.

2.Ensure the stability of the plants by using adequate high-quality potting soil. You can use dirt, coconut coir, sawdust, sand, and bonemeal to make your own potting mix, or purchase one from your local garden centre. Add compost to your plantings if they are edible. Make sure the box is completely filled. 

3.Add water and mix thoroughly. If the soil has settled, stir it again, then add more soil, moisten it, and add more water if necessary. Frequent watering and fertilizing are essential. Direct sunlight will cause plant boxes to dry out quickly!

4.Replace plants that have finished blooming with new ones without hesitation!


In conclusion, there are many great plants for flower boxes, so it is up to the homeowner to decide what will work best in their particular space. With a little research, the perfect plants can be chosen and enjoyed for years.


What evergreen is ideal for a window box?

Norwegian spruce (Picea abies spp.) and creeping juniper are cold-tolerant evergreens worth cultivating in a window box (Juniperus horizontalis). If evergreen bushes overrun the window box, transplant them into the ground. Into the potting soil, insert a couple of blooming bulbs.

What do you always put in window boxes?

Planting evergreens is the simplest, least work-intensive solution. They won’t need to be replanted from season to season and will (nearly) take care of themselves. Also, they are a fantastic option for window sills shaded by the sun.

What kind of plants belong in a planter box?

The rule of thumb is that putting three or four plants in 10 to 12-inch pots, four to six in 14 to 16-inch planters, and six to eight in 16 to 20-inch planters will beautifully fill the containers while giving room for the plants to develop without being overly crowded.
