Windowsill Growing.


A windowsill if often a great place to grow a plant. Many of the current commercial houseplants are suitable for growing on windowsills.

You can feed your windowsill plants quickly and easily just with Tgrowbags.

Many shade loving orchids will grow and flower on windowsills, these include Phalaenopsis hybrids, Paphiopedilums, Zygopetalums, and various intergeneric hybrids. We suggest you give them a go and see how they respond!

However there are a few watch points.

  • Not all windowsills are the same and some care should be taken with plant selection.

  • In the northern hemisphere a north windowsill have little sunshine, in contrast to many southern windows which will receive far more sunshine.

  • Net curtains or blinds can limit the amount of sunshine received by your plants

  • Modern double glazing considerably reduces the amount of usable sunshine a plant will receive compared to simple single glass panes

  • Care should be taken in winter months that plants are not chilled during the nighttime if curtains are closed. Sometimes it may be necessary to move plants into the room at night to avoid chills.

  • A radiator under a window can cause plants to dry out more when they are giving out large amounts of heat.

Feed your plants only when they are growing well. Sometimes they will grow quicker in the winter months when the central heating is on.


Plants need sunshine and light to live and thrive. Many modern houseplants are low light plants, however that does not mean they like dark gloomy rooms. In most cases you will get better growth if your plant receives light. This is why plants do well on windowsills. Remember the green leaves need sunshine to produce photosynthetic generated food.

Plants are not generally very good at adapting to quick changes in light intensity. A plant grown in the shade, inside a room, may burn if it is suddenly put on a sunny windowsill. To achieve a safe transition, simply put some shading up to protect it for 7-14 days or increase the hours of sunshine exposure over a similar time period.

Watch out for sunburn indicators such as marks on the foliage, dying cells and pigment changes. A quick removal from any sun may resolve the problem, However if the plant leaves have burns there may not be any remedy other than allowing the plant to grow new leaves. Sometimes damaged leaves should be removed.
