Pruning
  • water dropWater

    For Lesser Spearwort, which is a common name for Ranunculus flammula, maintaining moist soil is crucial. It thrives in wet environments, so water the plant thoroughly when the top inch of soil feels dry to the touch. Typically, this means watering at least once or twice a week, depending on weather conditions. Use about 1 gallon of water each time for a medium-sized plant to ensure the soil is adequately moistened. During hot or windy weather, you might need to water more frequently to prevent the soil from drying out.

  • sunLight

    Lesser Spearwort prefers full sun to partial shade. The ideal spot for this plant is an area that receives at least 6 hours of sunlight a day but is also protected from the harsh afternoon sun, especially in hot climates. A spot that offers morning sunlight and dappled afternoon shade would be optimal for the growth and flowering of Lesser Spearwort.

  • thermometerTemperature

    Lesser Spearwort best grows in temperatures that range between 50°F and 75°F. It can survive in temperatures as low as 20°F but is at risk if the temperature drops below that mark. During the growing season, maintaining an environment within this ideal temperature range will help the plant thrive and bloom.

  • scissorsPruning

    Pruning Lesser Spearwort is needed to remove dead or yellowing leaves and spent flowers to encourage fresh growth and maintain a tidy appearance. Pruning can be done throughout the growing season as needed. The best time to do heavy pruning is in late winter or early spring before new growth begins, cutting back any old growth to make way for new shoots.

  • circleLife cycle

    Lesser spearwort (Ranunculus flammula) begins its life cycle as a seed, often dispersing in close proximity to the parent plant in suitable wet or marshy habitats. Upon germination, the seedling emerges and develops roots and a rosette of leaves at the soil surface. As the plant matures, it produces elongated stems and more leaves, and being semi-aquatic, it adapts well to both saturated soils and shallow water. During the flowering stage, usually in late spring to summer, the plant bears bright yellow, buttercup-like flowers that attract pollinators, leading to the production of fruits called achenes. Once pollinated, these achenes mature and contain the seeds that will disperse to start the next generation. The plant may die back in winter, particularly in colder climates, but can also behave as a perennial, resprouting from the rootstock when conditions improve.

    • Propogation time

      Spring-Early Summer

    • Propogation: Ranunculus flammula, commonly known as Lesser spearwort, is typically propagated through division. The best time to propagate the plant is in the spring as the weather starts to warm up but before the plant has put out a lot of new growth. To propagate by division, carefully dig up the plant and gently separate the roots into smaller sections, making sure that each new section has some roots and some shoots. These sections can then be planted into a mix of soil and compost to encourage good root development. Water the new plantings adequately to help them establish.
