Pelargoniums are available in many colors from white to red, shades of pink and
purple or salmon. The flowers can be single or double. Just keep in mind
double flowers don't cope with rain as well as the single ones do.
You have the choice between different types of geraniums: the trailing ones also called ivy-leaf Geraniums or the upright
varieties referred to as Zonal Geraniums.
You can grow them outdoors or indoors in conservatories or on sunny
How To Care For Geraniums
Geranium care is not rocket science. Like all other plants they need
regular watering and feeding. Avoid over-watering and keeping the
rootball too wet
as this can cause root-rot. Use a good quality fertilizer
once a week.
Choose a sunny spot for Geranium plants. They like to be in the sun for
most of the day. In a shaded spot they won't produce many flowers and
to become leggy.
Geranium Care Tips
How To Deadhead Geraniums
Deadheading Geraniums is important to keep them looking their best and flowering over a long
period. It also helps to avoid fungal diseases like Botrytis,
particularly in damp
weather. Rainy weather can turn the flowers into unsightly mush! If they are not dead-headed the whole plants can get affected by fungal disease.
A lot of people make the mistake of only removing the actual flower.
This way you will end up with an ugly yellowing stem which can cause fungal diseases to get hold. Instead remove the
of the flower as well. It is usually a couple of inches long. Break them
off where they attach to the plant. They snap off easily so there is
no need to
use scissors or knifes.
Growing Geraniums in Containers
Bedding Geraniums are great container plants. The upright Geraniums can be used as a center piece for a larger container. They combine very well
with trailing annual flowers like Lobelia, Bacopa, Millionbells (Callibrachoa), Bidens or Verbenas.
The trailing geraniums (ivy leaf) can be grown in
hanging baskets, window-boxes or tall urns. Three plants are enough for a
13 inch basket or pot.
You can use a few filler plants like Lobelia, Viola or Alyssum with
And don't forget: regular feeding and watering is a must if you want a great looking summer display!
How To Overwinter Geraniums
For overwintering you need a glasshouse or a cooler but bright
room. They need to be overwintered frost-free. The ideal temperature is
between 41-47°F/5-8°C. Keep the plants drier during the winter
months. If they are kept too damp during the winter they will start rotting and you will loose the plants.
In the spring cut the plants back by about half.
This material can be
used for propagating geraniums. Take cuttings and insert them into
potting compost. Transplant them to individual containers once they have taken root.
Re-pot the overwintered plants in new potting soil in the spring and start feeding and watering
Dealing With Pests and Diseases
Greenflies can become a problem. An organic pest spray
will take care of them. An organic fungicide
will help to protect your plants from fungal diseases which should only occur in damp weather conditions or if it is too cold.
Growing Geraniums Indoors
Pelargoniums are great plants for hot window-sill or conservatories. In these hot spots you often have trouble growing other house plants because they burn
from the sun. Geraniums though tolerate that well and they flower!
Geranium care and maintenance is the same as above. Just keep in mind that the
plants might require a lot of watering if they are placed on a hot window ledge.
Transplant them into a larger container. This will make keeping them watered easier and they will produce more flowers over a longer period.
