Aat a window provides plants with strong indoor light, whichever way the window faces. Plants on an east-facing windowsill will receive good light to promote healthy growth without suffering from sun scorch.
Light from the east
Early morning sun, when it shines, is less hot than the mid-day or afternoon sun. This means that plants in an east-facing window receive a more even light throughout the day. A north window, which receives no sun, has the least variable light of all.
Place a plant at the side of a window and the light it receives drops surprisingly. Buildings blocking out sun and light in cities, and trees in the country, will also affect the amount of light available to plants on a window sill, no matter which way the window faces.
If you have a favourite plant which does not suit the light of the window, net curtains or semi-opened blinds over the glass will filter through the light, reducing its impact. It is then safe to let the plant rest there, providing you ensure that it does not get too hot and that itsrequirements are closely observed.
The plants you choose to use will, to some extent, be governed by the size and shape of your windows.
Full-length windows are usually also walk ways, so need to be at least partially unobstructed. In winter, when french windows anddoors are in less frequent use, this is a good position for exotic plants brought indoors to protect them from the frost. They will need nighttime protection, however. Identical plants placed on either side of the window look very effective but in this position they will receive much less light than those placed in front of the glass. All will need turning regularly so that all sides of the plant receive their share of direct light.
Small windows usually need small plants, unless the view would be improved by hiding it. In this.case, glass shelves across the window or trellis placed over at least part of it can give you an attractive curtain of plants. Screw a shelf slightly below a small window so plants displayed on it will receive necessary light for growth but thewill not stop light or hide the view. A neat effect will be created if you place plant pots in an indoor window-box screwed on brackets to the wall below the window. Set the containers on a tray with a layer of pebbles and surround them with peat and you will provide necessary too.
Wide windows give you a chance to mix plant sizes and shapes. A group of plants, backed by a climber growing up one side of the window, would still leave space for plenty of light to enter the room and a view to be enjoyed. Strategically placed, the plants could be used to obliterate an ugly object outside.
Tall, narrow windows provide space for taller plants. A plank of wood screwed across the bottom of the window can hide pots and protect plants from being knocked off the sill. If the window is over-tall use a climber, placed on the sill or on a ledge above the window, rather like a café curtain, training it on wires or trellis across the window to create a squarer shape.
Turn plants regularly, as they are receiving a lot of light from only one direction and this can result in uneven growth.
Don’t sandwich plants between curtain and glass in winter. This is the coldest position in the room at night. Try rather to pull curtains or blinds behind the plants to protect them. If this is difficult, use a small table in front of the window as a plant stand instead of the sill.
On cold winter days the window sill can be a cold spot, unless you have double glazing. Make sure that plants are not pressed against the glass.
