How many petunias are in a window box?
Likewise, how many plants should be in a window box?
Generally I would use 3 or maybe 4 plants in 10 or 12-inch planters, 4 to 6 plants in a 14 to 16-inch planter and Six to 8 plants in an 16 to 20-inch planter and so on. With the traditional planting, you need to have a bit of patience to get a completely full planter.
Additionally, what should I plant in my window box? Petunias, geraniums, zinnias, nasturtiums, and begonias are good choices for main-theme flowers. Fill in with things like wandering jew, ivy, euonymus, heather, or vinca, which will cascade over the edge of the box. Impatiens do well in shady locations. More subtle choices include coleus, heliotrope, and salvia.
Keeping this in consideration, how many impatiens can you plant in a window box?
The most common variety in the United States, Impatiens walleriana, is easy to maintain, grows well in containers, and comes in a wide range of colors like pink, red, purple, orange, and yellow. Available on Burpee; $6.29 for 30 seeds and $25.99 for 12 plants.
Why is the color of plant pots important?
These colors absorb heat and will get very hot, which can damage tender roots. Light colored containers reflect the heat and keep the roots cool.
