Geranium How to Plant, Cultivate And Take Care Of Them

Here's how to grow geraniums in your home and garden!

Note: This page is about plants of the genus Pelargonium, commonly known as geraniums or storks. Plants of the genus Geranium are also commonly used in gardens, but are usually called sturdy geraniums or cranesbill.

Although they can be kept outdoors during the hottest part of the year, geraniums are usually kept indoors for the winter. If they have enough light, they can bloom indoors all year round.

Geranium or pelargonium? Don't be mistaken anymore

Generally, flowering annual perennial plant, fragrant, native to South Africa that grows in sunny climates.

And, this star of balconies, blooms from May until December and beautifies terrace, bed, border or garden.

Geranium plantation

When buying geraniums, pay close attention to color and size. Healthy leaves will not have any discoloration on or underneath and the stems will be strong, not irregular. Also be sure to avoid any plant with obvious signs of pests.

Place plants in pots with drainage holes to prevent root rot.

Use well-drained soil (not heavy clay soil) when planting in pots. Geraniums do not like to stay in wet, compacted soil.

For maximum flowering, place the plants in a place where they will benefit from 4 to 6 hours of sunshine.

Geranium maintenance

Allow the soil to dry to some extent between waterings, then water thoroughly.

During the winter, water much less, but don't let the roots dry out completely. Geraniums work best when they are given a dormant period during the winter months when they use less water and do not grow much.

  • To encourage flowering, dead flowers are removed.
  • To encourage bush growth, pinch the stems.
  • During the months of active growth, fertilize every 2 weeks. Use a half-concentrated water-soluble fertilizer. Do not fertilize in winter.
  • Geraniums can be repotted as needed in the spring to be refreshed.

Geraniums in winter

Geraniums that have spent the summer outdoors can be kept as houseplants, provided they get plenty of sunshine. In northern climates, the sun may not be strong enough in late winter to stimulate buds on some varieties.

Before the first frost in the fall, lift the plants and, using a clean, sharp knife, cut the stems into a curved shape about 15 to 20 cm.
  • They should not have to support large masses of leaves in the low sunlight environment they are about to enter.
  • Keep a few stems as rooting cuttings, an easy way to propagate your plants.
  • Transplant the "mother plant" into the smallest pot possible, but large enough to fit the roots, using ordinary potting soil.
Keep the plants in the shade for a week, then place them in a sunny spot (they need all the sun they can get) and keep them cool.

During winter, geraniums grow best with night temperatures of 10° to 16° C but survive if they fall to 0° C) and/or rise above 27° C, as long as they are kept relatively dry.

When new shoots appear, cut off all old leaves.

The only thing more difficult than making new growth appear is to keep it. And here's some help with that:
  • Water only when the leaves show signs of falling and only provide small amounts. Do not fertilize or feed the plants. It is essential that the plants rest.
  • Once the warm weather has returned and any danger of frost has passed, put the plants outside and transplant them into the garden or pots as you wish.
  • Geranium plantation: Disease and pest
  • Common problems can be low light or too much or too little water. Leaves will yellow to indicate that you are watering too little or too much.

If this happens, try to even out the watering and move the geraniums to a brighter spot.

Geranium Planting: Cuttings

Most geraniums root easily from stem cuttings in soil, coarse sand, water, perlite or other rooting material, but not with fertilizer.
  • 1 - Using a clean, sharp knife, make an oblique cut 10 cm below the end of the stem, above a node where the leaves emerge. Cut the cut just below a node. Remove all buds, all but two or three leaves, and the leaf-shaped stipules at the base of the leaf stems.
  • 2 - Roll the cut stem in newspaper or put it in the shade for 24 hours, so that the cut end heals and does not rot.
  • 3 - Put the stem in a damp rooting medium pot and store it in a warm and shady place for 2 days. After that, give it some indirect sunlight. Moisten the medium only if necessary.

Further information :

  • For minor cuts, apply crushed geranium leaves to stop bleeding.
  • In the language of flowers, scarlet geranium means stupidity.
  • Geraniums are known to be toxic to Japanese beetles, so you won't have to worry about these annoying pests.
