  • water dropWater

    For the Geranium 'Sirak', commonly known as cranesbill, it is important to water the plant moderately, ensuring that the soil is kept evenly moist but not waterlogged. During the active growing season in spring and summer, watering once a week with approximately 16 ounces of water per plant should be sufficient. During the cooler months, reduce watering to every other week as the plant's water needs decrease. Always check the top inch of the soil; if it feels dry, it's time to water. Avoid overhead watering to prevent leaf and flower diseases and water at the base of the plant instead.

  • sunLight

    Cranesbill Geraniums thrive in conditions where they can receive full sun to partial shade. A spot that provides morning sunlight and some afternoon shade would be ideal. Ensuring adequate light can help the plant produce the vibrant blooms it is known for. The best lighting scenario is to place your Geranium 'Sirak' in a location where it can enjoy at least 4 to 6 hours of sunlight daily.

  • thermometerTemperature

    Cranesbill Geraniums prefer temperate conditions and thrive best in temperatures ranging between 65 and 75 degrees Fahrenheit. They can tolerate temperatures as low as 50 degrees Fahrenheit and as high as 80 degrees Fahrenheit. It is crucial to avoid exposure to temperatures below 32 degrees Fahrenheit, which can cause severe damage or kill the plant.

  • scissorsPruning

    Pruning Cranesbill Geraniums is done to encourage bushier growth, remove spent blooms, and rejuvenate the plant. It's best to prune in early spring to shape the plant and remove any dead or damaged foliage. Deadheading, or the removal of faded flowers, can be done throughout the blooming season to promote continuous flowering. Cut back the entire plant by one-third after the initial wave of flowering to encourage a second bloom period.

  • circleLife cycle

    The life of the Geranium 'Sirak', also known as Cranesbill 'Sirak', begins with seed germination, which is influenced by temperature and light conditions; however, many gardeners prefer vegetative propagation for uniformity. The next stage is seedling growth, where the plant develops its root system and initial leaves. As it grows, the plant enters the vegetative stage, producing a rosette of leaves and eventually branching out. The plant then reaches maturity with the onset of flowering, presenting delicate blooms that attract pollinators and aid in reproduction. Following pollination, the plant produces fruit, each containing seeds that can disperse to produce new plants. Finally, in perennial climates, the Geranium 'Sirak' enters dormancy during the colder months and re-emerges in spring; in annual or biennial scenarios, the plant would complete its life cycle and die after seed production.

    • Propogation time

      Spring-Early Summer

    • Propogation: For Geranium 'Sirak', the most popular method of propagation is through stem cuttings. This process is ideally carried out in late spring to early summer when the plant's growth is most active. To propagate, select a healthy stem and cut a 4 to 6 inch section just below a node, ensuring there are at least two sets of leaves on the cutting. Remove the bottom leaves to expose the nodes and dip the cut end into rooting hormone. Then, plant the cutting in a pot filled with moist, well-draining soil or a mixture of peat and perlite. Covering the pot with a plastic bag can help maintain humidity levels. Place the pot in bright, indirect light and keep the soil consistently moist until the cutting roots firmly, which typically takes about 3 to 4 weeks.
