Germination

Here’s an easy guide to help your seeds germinate and grow strong:

Chill the Seeds for Better Growth: To boost germination, keep seeds with a slightly damp paper towel in a Ziploc bag in the refrigerator for 7 days. Alternatively, soak the seeds in warm water for 24 hours.

Plant Seeds Directly Outdoors: After treatment, plant seeds outdoors in spring or summer, no later than August 1. Place them 1/4 inch under loose soil and about 12 inches apart.

Transplant Seedlings at the Right Time: If starting seeds indoors, transplant them when they’re 4 to 6 weeks old. At this stage, they haven’t yet developed a long tap root, so they’re easier to move.

Prepare the Soil for Transplanting: When transplanting, dig a hole twice as wide and 1/2 inch deeper than the seedling’s container. Place each plant about a foot apart for the best growth.

How To Grow

Soil and Location Needs:

Lupines thrive in moist, sandy soil that drains well. They prefer moderate temperatures.

For heavy soil, loosen it to make room for their long taproots.

Plant in a spot with full sunlight or partial shade.

Watering Tips:

Water regularly during the first few months to help roots grow, letting the soil dry out between waterings.

After that, water only during very dry periods or droughts.

Care Tips:

Step 1: Feed the plants with fertilizer every four weeks during the summer.

Step 2: For taller lupine types, you may need to stake them for support.

Step 3: Remove wilted flowers to encourage more blooms.

Step 4: Collect seeds when the pods turn yellow.

Step 5: In spring, cut back any dead spikes.

Step 6: Add mulch around the plants for winter protection.

Pests & Disease

Here’s what to watch for to keep your lupine plants thriving:

Prevent Powdery Mildew: Lupine plants can get powdery mildew, especially in hot, humid areas where they don’t adapt well. Keeping the plants in cooler, well-ventilated spots can help prevent this.

Watch Out for Birds: Birds might eat uncovered seeds, so cover them lightly with soil when planting to keep them safe.

Beware of Pill Bugs: Seedlings and seeds can attract pill bugs (roly-polys), which may nibble on them. Keep an eye out for these bugs if they’re common in your area.
