“Bulbs for planting now” depends on the season and your local climate. Spring-flowering bulbs, such as tulips and daffodils, are generally planted in autumn; summer-flowering bulbs, such as dahlias and gladiolus, are usually planted in spring after frost danger has passed. This guide helps you choose what suits the current conditions and plant it successfully. Before buying, check the bulb packet for planting dates and your area’s expected frost dates—timing varies by region.
What You’ll Need
- Healthy, season-appropriate bulbs, corms, or tubers, with their labels
- A sunny or appropriately shaded planting spot with soil that drains well
- A trowel or bulb planter and, if needed, a garden fork
- Compost for improving poor soil, plus mulch for winter protection where appropriate
- Water and gardening gloves
Step-by-Step
- Work out what can be planted now. In autumn, plant hardy spring bloomers such as daffodils, crocuses, hyacinths, and tulips. In spring, plant tender summer bloomers such as dahlias, begonias, and gladiolus once the soil has warmed and hard frost is no longer expected. Some hardy bulbs have different schedules, so follow the packet and local advice. If the ground is frozen, waterlogged, or too hot and dry to work, wait for suitable conditions.
- Choose a suitable variety and location. Match the plant to the amount of sun, soil, and space you have. Most flowering bulbs do best in full sun or light shade and well-drained soil; woodland types may prefer partial shade. Check the expected height and flowering time, and group varieties with similar needs. Avoid spots where water pools after rain, since persistently wet soil can rot bulbs.
- Check the planting material. Choose firm, sound bulbs or tubers without soft, mushy, moldy, or badly damaged areas. Keep them cool, dry, and ventilated until planting, and plant promptly rather than leaving them in a warm room or sealed plastic bag. Do not peel away healthy outer skins. Discard material that is clearly rotten.
- Prepare the bed or container. Remove weeds and loosen compacted soil. Mix in compost if the soil needs improvement, but avoid adding fresh manure directly beneath bulbs. For containers, use a pot with drainage holes and fresh, free-draining potting mix. If your garden soil is heavy clay, improve drainage across the bed or choose a raised bed or container; a layer of gravel at the bottom of a planting hole does not fix poorly drained soil.
- Plant at the right depth and orientation. Use the packet’s depth and spacing as the main guide. For many hardy bulbs, a useful starting point is planting at about two to three times the bulb’s height, measured from the base to the soil surface; some types need different depths. Put pointed tips upward when visible and roots or basal plates downward. If a bulb has no obvious tip, plant it on its side. Dahlias and other tubers should be planted according to their specific instructions, not treated like small spring bulbs.
- Space bulbs for the display you want. Follow the label’s spacing for healthy growth. For a natural-looking patch, plant small groups or loose drifts rather than precise rows; keep bulbs close enough for a full display but not touching. In pots, they can often be placed closer together than in a border, provided they do not press against one another and the container is deep enough for the chosen variety.
- Backfill and water appropriately. Cover the bulbs with soil and gently firm it without crushing or compacting it. Water after planting if the soil is dry to settle the soil around them. Do not keep the area saturated. Autumn-planted bulbs in cool, damp ground may need little extra water, while containers can dry more quickly and should be checked regularly.
- Label and protect the planting. Mark the variety and planting location so you can avoid digging it up later. Add a light mulch where helpful to moderate temperature and retain moisture, but do not bury shoots under a thick layer. If squirrels or other animals disturb bulbs, use a suitable physical barrier, such as securely anchored mesh, or choose less vulnerable varieties.
- Maintain the planting as it grows. Check containers and beds for drying or standing water. After flowering, let foliage remain until it yellows naturally; leaves replenish the bulb for future blooms. Remove spent flowers if you want to discourage seed formation, but do not tie, braid, or cut healthy leaves early.
Common Mistakes
- Planting the wrong group for the season: Tender summer bulbs planted into cold, wet soil may rot or be damaged by frost. Hardy spring bulbs planted too late may have little time to root. Use the plant label and local frost guidance.
- Guessing at depth: Shallow planting can leave bulbs exposed or unstable; planting too deeply can delay or prevent flowering. Check the label and use the height-based guideline only as a starting point.
- Choosing a waterlogged site: Poor drainage is a common cause of bulb loss. Change the site, improve the bed, or grow bulbs in a draining container rather than watering more.
- Cutting foliage too soon: Green leaves are feeding the bulb. Wait until they turn yellow and die back naturally before removing them.
- Keeping bulbs in unsuitable storage: Warm, damp, or airtight storage encourages drying, mold, and rot. Store unplanted bulbs in a cool, dry, ventilated place and follow any specific storage directions.
Tips
- For a low-maintenance spring display, plant several varieties with staggered flowering times and similar growing requirements.
- When planting a lawn, choose bulbs suited to naturalizing and avoid mowing the area until their foliage has yellowed.
- Use containers to control drainage and make tender varieties easier to protect from cold. Ensure pots do not sit in water-filled saucers during wet weather.
- Keep the packet or record the variety, planting date, and location. This makes it easier to identify shoots and adjust next season’s planting.
- Check whether bulbs are toxic to pets or people before planting, especially if children or animals may dig or chew them. Store bulbs out of reach.
Troubleshooting
Nothing has sprouted: Check the variety’s normal emergence time and the weather before digging. Some bulbs take weeks or longer, and cold conditions can delay growth. If the expected period has passed, carefully uncover one bulb. A firm bulb may still be viable; a mushy or foul-smelling one has likely rotted. Improve drainage before replanting.
Shoots appeared before winter: Mild weather can trigger early growth in some bulbs. A cold spell does not always kill them. Apply a loose mulch for protection, and avoid walking on or cutting the shoots.
Leaves grow but flowers do not: Possible causes include planting too shallowly or deeply, insufficient light, overcrowding, premature foliage removal, or a bulb that has not matured. Let leaves die back naturally, then review the location and planting depth. Lift and divide crowded clumps after foliage has died back if the variety allows.
Bulbs are soft or rotting: Remove affected material and do not compost diseased bulbs. Reduce excess watering and improve drainage; replace the planting site or use fresh potting mix if needed. Avoid replanting sound bulbs in the same persistently wet hole.
Bulbs have been dug up: Replant undamaged bulbs at the correct depth and firm the soil. Protect the area with anchored mesh or another suitable barrier, ensuring emerging shoots can pass through.
Frequently Asked Questions
Can I plant bulbs at any time of year?
No. Planting time depends on the type of bulb and local climate. Hardy spring-flowering bulbs are usually planted in autumn; tender summer-flowering types are generally planted in spring after frost risk has passed.
What bulbs can I plant right now?
Check the current season, soil temperature, and local frost forecast. Use labels from reputable suppliers or a local gardening service, since planting windows differ by region and by variety.
How deep should I plant bulbs?
Follow the packet. For many hardy bulbs, planting at two to three times the bulb’s height is a useful guide, but some types—including tubers—need different treatment.
Do bulbs need watering after planting?
Water once if the soil is dry, then keep it lightly moist as appropriate for the plant and weather. Avoid waterlogged soil, which can cause rot; check containers more often because they dry out faster.
Can I plant bulbs in pots?
Yes. Choose a container with drainage holes, use fresh potting mix, and follow the variety’s depth and spacing guidance. Protect pots from severe cold if the bulbs are not reliably hardy in your area.
Should I remove leaves after the flowers fade?
Not while they are green. Leave foliage in place until it yellows naturally so the bulb can store energy for next year.
