Care of Indoor Plants
Generally, no indoor plant appreciates being sited in a cold or draughty position. Many require a minimum temperature of 16 degrees Centrigrade to flourish. They also tend to need more watering than outdoor plants as clearly their roots cannot access ground water and the warmth of home interiors evaporates their water more quickly.
- Repotting. Use a special citrus compost as it is a rich, slightly acidic growing medium. It is essential to add a drainage layer at the base of the pot (broken pots are ideal). Should the roots expand to fill the pot then the plant can be repotted in the growing season.
- Watering. Avoid waterlogging. In Summer keep the compost fairly moist with lime-free water and remove any excess.
- Feeding. Use a citrus feed and follow the growers’s recommendations. Both Winter and Summer feeds are available.
- Pruning. Keep the shape with regular clipping of top shoots. Wait until Spring for the occasional and more radical pruning.
- Position. In Summer citrus plants may be placed outside in a sunny, sheltered position. In Winter place in a cool porch or conservatory but at a minimum temperature of 5 degrees Centrigrade.
- Pollination. If your citrus tree bears flowers, but no fruit, this might be because it is not being pollinated. Ensure that pollinating insects can reach the trees, by leaving conservatory and greenhouse doors open occasionally on fine days and moving trees outside once summer has arrived.
- Flowering. Amaryllis tend to flower from Christmas through to the end of May. Once it has flowered, cut off the faded flowers and let the leaves continue to develop.
- Watering. Once the plant has finished flowering it will need more watering but stop watering it in September until it flowers.
- Position. Keep in a warm room in sunlight at about 20 degrees Centrigrade or in a sheltered spot in the garden from May to September.
