Gloriosa Planting & Growing Guide

Where to Plant

Plant your Gloriosa where the soil drains well, and it will receive partial sun to light shade. In warmer climates where the sun is strong, a spot with a bit more shade is preferable. If you notice water puddles in your outdoor site 5–6 hours after a hard rain, scout out another site or amend the soil with organic material to raise the level 2–3" and improve the drainage. They will grow well in most moderately fertile soil but will not survive in soggy conditions or standing water.

When to Plant

Plant your Gloriosa Lily bulbs in the spring after the soil has warmed and the danger of frost has passed. You can also give them a jumpstart earlier in the season by planting indoors to move outside after the final frost.

How to Plant

• For outdoor landscape planting, find a location where the soil drains well, and your plants will receive partial sun. Dig holes and plant the bulbs 3–4" deep and 8–12" apart, taking care not to touch the bulbs' growing points. Simply lay the bulbs on their sides in the holes and gently cover them with soil.
• For container planting, choose a large container with adequate drainage holes and fill it with good quality, well-drained soil. Site your plants where they will receive partial sun to light shade. Dig holes and plant the bulbs 3–4" deep and 8–12" apart, taking care not to touch the bulbs' growing points. Simply lay the bulbs on their sides in the holes and gently cover them with soil.
• Water generously, soaking the soil to settle it around the bulbs.

How to Grow

• Water periodically during the growing season if rain does not occur, keeping in mind that weekly deep waterings are better than lighter drinks every day or two. About 1" of water per week is a good estimate of the amount needed during active growth periods.
• Apply half-strength fertilizer to the water every two weeks to keep your Gloriosa blooming vigorously throughout the summer (and sometimes into early fall!).
• Leave the foliage in place after flowering has finished for the season. The leaves will gather sunlight, create food through photosynthesis, and strengthen the bulb for the future.
• Remove leaves and stalks when they turn yellow.
• Lift the bulbs for storage if you garden in a region cooler than zone 9. Place them in lightly damp peat moss and allow them to rest for a few months before replanting and beginning the next growing cycle in the spring.

Gloriosa Tips & Tricks

• Amend the soil with compost, finely ground bark, or decomposed manure to raise the level 2–3" and improve the drainage.
• Expect roots and sprouts to form a few weeks after planting, with flowers following shortly behind.
• Wait until the soil warms, if it's still cool in your region, before planting.
• Be mindful to avoid the growing points on the bulbs when planting, as bumping and abrading this area tends to reduce sprouting.
• Add some support structure for your vines to clamber up after planting.
