Lobelia Glow Electric Blue Rooted Cutting Liner

For best results with Glow Electric Blue, use well-drained soil with low feed (100-150 ppm N), a pH of 5.6-6.2, and an EC of 1.0-1.2. Plant two or three rooted liners per 4-inch container or 5 plugs per 10-inch basket. Maintain temperatures between 65-68 degrees. This plant doesn't have major pest or disease problems, but does need full sun and regular water to thrive. You may see aphids, whiteflies, or thrips. 

Small blue flowers bloom from early spring until frost.

We recommend that you first pinch Glow Electric Blue 5-10 days after transplanting to your final container. Pinch early and soft to promote good basal branching.

Lobelia should be spaced adequately to allow airflow and light penetration between the foliage. Usually 2’ centers on baskets will be enough.

B-Nine, A-Rest and Bonzi have all been tested on Lobelia and are effective. In our experience, pinching is sufficient to create a well-shaped basket. If you decide to use PGRs, follow the label’s instructions. Danziger recommends a 2 ppm drench of Bonzi as needed to combat stretching.

Aphids, whiteflies and thrips are the primary pests attracted to Lobelia.

Glow Electric Blue isn't disease prone but avoid oversaturating the soil. If the plant sits in moist soil at length, you could end up with root rot or botrytis. Botrytis grey rot tends to occur in wet or humid conditions. Take these steps to prevent botrytis: water in the morning and allow the plant to dry out between waterings; provide good airflow in your greenhouse; space plants so the sun can penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.

1. We recommend planting 5 starter plants per 10-inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, completely covering the ellepot with the soil. If you are planting 4-inch pots, use 2-3 plants per pot. When using 3 starters, plant them in a triangle in the middle of your pot.
2. Pinch Glow Electric Blue 5-10 days after transplanting to your final container. Additional pinches every couple of weeks may be required to shape your final pot.
