Grow Plants For Window Boxes and Troughs

Window boxes are a lifesaver for gardens and houses, especially when it’s too busy to do anything else. They’re also a great option if you’re in the middle of building work. Troughs and window boxes provide some sort of garden, no matter what the land is like, with a cheerful view from both indoors and outside. If you have to work near the window, the plants can be easily removed.

Types of Window Boxes and Troughs

  • Ready-made available in many sizes, shapes, and materials.
  • You can make your own box out of timber or marine plywood. You can also make a brickwork trough to support the foundation of your house.
  • or, if find more inspirations from the 10 reusable household items that I listed previously.

Siting and Fitting a Window Boxes For Evergreen Plants

It is better to have a removable box so that you can access the window and ledge, and for maintenance and repairs. Boxes are heavy and likely to be broken away. To ensure your peace of mind, attach side brackets to hold them in place. To prevent sills from sloping dramatically, wedges can be used (homemade or purchased) to hold the box level.

How to set up evergreen plants for window boxes

Support a box underneath the window ledge to allow for windows to open. Use right-angled brackets or metal brackets. To screw the brackets into place, simply drill holes in the wall and use a spirit level. You can also choose a window box that is suspended from screws from the wall. These are only suitable for lightweight plastic boxes. However, a row of them under a large window is as effective as one large container and easier to move.

Planting Window Boxes and Troughs

Place the pots in the trough or box. They can then be easily steamed out, either for house maintenance or swapping plants. To disguise pots, fill the box with compost before you plunge them. You can also place the pots first and then cover them with bark mulch, stone chips. You can also fill the container with compost, and then plant it directly.

General Plant Care for Evergreen Plants Growing in Window Boxes or Troughs

Plants in boxes or troughs require more attention than garden plants. There is only a small amount of compost that can hold in moisture during dry spells and heat in colder weather.

Watering evergreen plants in window boxes

  • Watering is essential – either by hand or automatically by using a patio drip irrigation kit or a system from Gardena, Hozelock or an automated system.
  • Before planting, add a water retention gel. The gel slowly releases water as the plants require it.
  • Self-watering containers can be useful, provided you remember to refill the reservoir frequently.

Drainage and insulation

  • The roots will die if they are suffocated by waterlogged compost.
  • Waterlogged compost in Winter would freeze solid, killing the plants growing in it.
  • If drainage holes are not present, you can add them.
  • Insulate winter boxes or troughs. Use bubble plastic or polystyrene packing chip to line the containers or wrap the pots around them.

Feeding and Other Care

  • Composts are quickly depleted of fertilizer. A tomato fertilizer can be used to fertilize your plants for fruiting and flowering.
  • For more flowers, please contact Deadhead.
  • For bushy growth, pinch out the tips.
  • If you want to plant permanent plants, trim your trailers in spring. To keep shrubs compact, remember to shear them in summer.
