FAQ About Window Box DIY
Q: What is the best wood to use when building window boxes?
A: Cedar and redwood are ideal because they are naturally resistant to rot, insects, and decay. Avoid using treated lumber which can leach chemicals.
Q: How can I make DIY window boxes on a budget?
A: Use inexpensive materials like pine boards and exterior plywood. Opt for smaller boxes that need less material. Recycle plastic containers or wood scraps when possible.
Q: How do I mount a window box securely?
A: Use sturdy cleats, brackets, or corbels attached to strong points on the house framing. For heavier boxes, place supporting brackets every 12-16 inches along the length.
Q: Should I put drainage holes in my DIY window boxes?
A: Yes, drilling several drainage holes in the bottom allows excess moisture to escape, preventing root rot. Line the boxes with landscape fabric or plastic sheeting first so soil doesn’t wash out.
Q: What kind of soil or mix should I use in window boxes?
A: A quality potting mix amended with compost provides the drainage and nutrients plants need. You can also use soilless media like peat and coir. Add perlite or vermiculite to improve drainage.
