Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continued blooming and prevent excessive self-seeding if desired.

How do I propagate Dame's Rocket?

Dame’s Rocket is most commonly propagated by seed. Collect seeds from dried flower heads in the fall. Sow seeds directly into the garden in the fall or early spring. Alternatively, start seeds indoors 6-8 weeks before the last frost.

Philodendron Selloum

What are the light requirements for Philodendron Selloum?

Philodendron Selloum flourishes in bright, indirect light. Avoid direct sunlight, especially during the hottest part of the day, as it can cause leaf burn. An east-facing window is ideal, or a spot near a south or west-facing window that is filtered by a sheer curtain. If the plant is not receiving enough light, the leaves may become pale or the stems may become leggy. Rotate the plant regularly to ensure even growth on all sides. Artificial grow lights can be used to supplement natural light, especially during winter months.

How do I care for Philodendron Selloum?

Philodendron Selloum thrives in bright, indirect light, avoiding direct sunlight which can scorch its leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Use a well-draining potting mix to prevent root rot. Maintain humidity levels around 60-70% through misting or a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune any yellow or damaged leaves to encourage healthy growth. Repot every 1-2 years as needed, when the plant becomes root-bound. Provide support for mature plants as they grow larger. Protect from drafts and sudden temperature changes.

How do I propagate Philodendron Selloum?

Philodendron Selloum can be propagated through stem cuttings, division, or air layering. For stem cuttings, take a cutting with at least one node and place it in water or moist soil. For division, carefully separate the plant into multiple sections, ensuring each section has roots. For air layering, make a small cut on the stem, wrap it in moist sphagnum moss, and cover it with plastic wrap until roots develop. Plant the rooted cutting or division in well-draining soil. Maintain high humidity during propagation.
