It is essential to ensure the soil is adequately drained to avoid rotting of the roots. The plant should be watered deeply to encourage deep rooting and reduce the frequency of watering.
Fertilization
Adding fertilizer to the soil can help ensure quality growth and blooming of the Ranunculus acris L. var. aestivalis plant. The plant requires adequate nitrogen, phosphorus, and potassium. The best time for fertilization is during early spring, before the blooming period. A balanced fertilizer with an NPK ratio of 10-10-10 or 12-12-12 should be used. The plant should be fertilized every four to six weeks until late summer.
Pruning
Pruning is an essential aspect of maintaining the Ranunculus acris L. var. aestivalis plant. The plant should be pruned after the blooming period to promote new growth. Remove any dead or damaged leaves and stems from the plant using pruning shears. This helps increase the plant's aesthetic value and promotes air circulation, reducing incidences of plant diseases.
Propagation of Ranunculus acris L. var. aestivalis (L. Benson) Welsh
Ranunculus acris L. var. aestivalis (L. Benson) Welsh, commonly known as Meadow buttercup, is a herbaceous perennial plant. It is easy to propagate and can be propagated by seed or division.
Propagation by Seed
The best time to sow seeds of Ranunculus acris L. var. aestivalis (L. Benson) Welsh is in the fall. The seeds can be sown directly into the garden bed or started indoors and transplanted later.
If you are starting seeds indoors, sow the seeds in moist soil in flats or cells. The seeds should be covered lightly with soil, and the container should be kept in a warm, sunny location.

To divide the plant, dig up the clump of plants and separate the crowns. Each crown should have several healthy roots and shoots. Plant the divisions in a prepared garden bed or in containers with well-draining soil.
Keep the soil moist and provide some shade until the plants are established. Ranunculus acris L. var. aestivalis (L. Benson) Welsh should start flowering in their second year.
Disease and Pest Management for Ranunculus acris L. var. aestivalis (L. Benson) Welsh
Ranunculus acris L. var. aestivalis (L. Benson) Welsh, commonly known as meadow buttercup, is a perennial plant that blooms in late spring and early summer. While this plant is generally hardy, it can be susceptible to certain diseases and pests that can affect its growth and overall health. Here are some common diseases and pests that may affect Ranunculus acris and ways to manage them:
Diseases
1. Root Rot: Root rot is a fungal disease that affects the roots of the plant and can cause wilting, yellowing, and eventual death of the plant. It thrives in moist soil conditions and can spread quickly. To manage root rot, make sure the plant is not overwatered and has well-draining soil. Remove any infected plants promptly to prevent further spread.
2. Rust: Rust is a fungal disease that produces orange or brown spots on the leaves of the plant. It can also cause the leaves to fall off the plant, ultimately stunting its growth. To manage rust, remove affected leaves and discard them. You can also use a fungicide to prevent further spread.
3. Crown Rot: Crown rot is a bacterial disease that affects the crown of the plant. It can cause the leaves to wilt and turn yellow or brown, and it can also cause root damage. To manage crown rot, remove any infected plants promptly and improve drainage in the soil.
Pests
1. Aphids: Aphids are small insects that suck the sap out of the plant's leaves, causing them to deform and turn yellow. They are also known to transmit viruses that can kill the plant. To manage aphids, use insecticidal soap or neem oil to control their population.
2. Slugs and Snails: Slugs and snails can cause extensive damage to the plants by feeding on the foliage and leaving behind slime trails. To manage slugs and snails, remove any debris or clutter around the plant, and use slug and snail bait or traps to control their population.
3. Spider Mites: Spider mites are tiny, brown or red pests that suck the sap out of the plant's leaves, causing them to turn yellow and drop off. To manage spider mites, use an insecticide specifically designed to control their population. You can also increase humidity around the plant to deter them from settling.
By following these tips, you can prevent disease and pest problems from ruining the health and beauty of your Ranunculus acris L. var. aestivalis (L. Benson) Welsh plants.
