Welcoming Spring: A Guide to Caring for Spring Bulbs

by: VickiS

One of the most enchanting signs of the changing season is the emergence of spring bulbs, heralding the end of winter dormancy with their vibrant blooms. Whether you’re a seasoned gardener or a novice enthusiast, caring for spring bulbs can be a rewarding and relatively straightforward endeavor.

Selecting the Right Bulbs: Before you can revel in the beauty of spring blooms, it’s essential to start with high-quality bulbs. When selecting bulbs, opt for those that are firm, plump, and free from blemishes or mold. Larger bulbs often produce more robust flowers, so choose the biggest ones available. Additionally, pay attention to the specific requirements of each bulb variety, ensuring they are suitable for your climate and soil type.

Planting Time and Location: Timing is crucial when it comes to planting spring bulbs. Aim to plant them in the fall, ideally six to eight weeks before the first hard frost. This allows the bulbs to establish roots before winter sets in. When selecting a planting location, choose a spot with well-drained soil and ample sunlight. Most spring bulbs thrive in full sun to partial shade, so avoid areas with dense shade or standing water, which can cause bulbs to rot.

Planting Depth and Spacing: The depth at which you plant spring bulbs depends on their size. As a general rule of thumb, larger bulbs should be planted deeper, while smaller bulbs can be planted more shallowly. A good guideline is to plant bulbs at a depth that’s roughly two to three times their diameter. Proper spacing is also essential to allow bulbs room to grow and expand. Aim for a spacing of two to three times the bulb’s width between each planting.

Watering and Fertilizing: Once planted, spring bulbs require minimal maintenance, but proper watering is crucial, especially during their active growing period. Keep the soil evenly moist but not waterlogged, as excessive moisture can lead to bulb rot. During dry spells, water bulbs regularly, aiming to provide around one inch of water per week. Additionally, a light application of balanced fertilizer in early spring can help nourish the bulbs and promote healthy growth and abundant blooms.

Post-Bloom Care: After the spectacular display of spring blooms has faded, it’s important to provide proper care to ensure the bulbs’ longevity and future flowering. Allow the foliage to wither and yellow naturally, as this signals the bulbs are replenishing their energy reserves for the next growing season. Avoid cutting back or removing the foliage prematurely, as it provides essential nutrients to the bulbs. Once the foliage has died back completely, you can gently remove it from the garden bed.

Dividing and Transplanting: Over time, spring bulbs may become overcrowded, leading to decreased flowering and overall vitality. Dividing bulbs every few years can help rejuvenate them and promote better bloom production. Wait until the foliage has died back in late spring or early summer, then carefully dig up the bulbs. Separate any offsets or daughter bulbs from the parent bulb, ensuring each division has its own roots intact. Replant the divisions in a well-prepared bed or share them with fellow gardeners to spread the joy of spring blooms.

Protecting Against Pests and Diseases: While spring bulbs are relatively low-maintenance, they can fall prey to pests and diseases if not properly cared for. Keep an eye out for common pests such as aphids, slugs, and bulb mites, and take appropriate measures to control them if necessary. Avoid planting bulbs in areas prone to waterlogging, as this can increase the risk of fungal diseases such as botrytis and fusarium rot. Proper sanitation practices, such as removing and disposing of any infected plant material, can help prevent the spread of disease.

In conclusion, caring for spring bulbs is a labor of love that rewards gardeners with a stunning display of color and fragrance each year. By selecting high-quality bulbs, planting them at the right depth and spacing, providing adequate water and nutrients, and practicing proper post-bloom care, you can ensure your spring bulbs thrive and delight for seasons to come. So, roll up your sleeves, dig in the dirt, and prepare to welcome spring with open arms and a garden bursting with blooms.

Transplanting Daffodils

4eb015c098194a88800061c2c8073efd--flower-gardening-organic-gardeningMoving to a new location? Or, maybe your daffodils have spread beyond the intended space? Or, maybe you want to share with others? The ideal time to dig up daffodils is about eight weeks after flowering, when the foliage has just started to yellow — and while you’re at it, you might as well divide the large-flowered ones. Small-flowered types can be left alone indefinitely, but most large-flowered daffodils must be divided every three to five years or you’ll end up with nothing but leaves.

Dig the new planting holes before you start, figuring that each old clump is probably getting overcrowded, should be divided, and so will need about three or four times as much space in the new location(s). Have extra soil and sod ready to fill in the old holes. Choose an overcast day, or work in the evening. Using a digging fork, putting it deep into the soil, cut a line around the clump about 2 inches from its outside edge. Keep working your way around, loosening the lifting, following the line you cut, until the whole clump is free. Lever it out, gently break it apart, and then work the sod away from the stems and set it aside for lawn repair.

Separate the bulbs, letting them fall naturally into smaller clumps that still have dirt 100_5200attached. Don’t tear the roots — you can hose off the roots, disentangle them, and do a more thorough job of dividing. Plant in the prepared holes, and water well.

Save the fertilizer for the fall. By the time daffodils (genus Narcissus) bloom, their leaves are almost finished transferring the carbohydrates they’ve made into the bulb for storage. As the chlorophyll breaks down and the leaves turn yellow, the plants need only sunlight, air, and water to finish up.

If you need to fertilize daffodils, do it in early spring just as new growth pops up, or in the fall when roots are growing and daughter bulbs are being formed. Use a balanced fertilizer or well-rotted compost to maintain nutrition in situations where the bulbs are crowded or are permitted to set seed, which takes a lot of energy.

Many gardeners also hedge their bets by mixing a bulb booster into the bottom of the hole when planting bulbs, because it is high in phosphorus, which does not move much in the soil. Phosphorus encourages root growth, the first order of business for a newly planted bulb.

Forcing Bulbs for Winter Color

by OCMGA Master Gardener Tammy Borden

Who says gardening has to wait until spring? By forcing bulbs you are convincing a 5af4ee4d3b54cd5096b5ab4cfa505ee1--indoor-flowering-plants-indoor-flowersspring bulb that it has slept through the winter months and are encouraging it to bloom early. It’s wonderful to have bright blooms and sweet scents during the grey and drab days of winter.

Forcing bulbs is not too difficult. It just takes time, patience, and a little advance planning. It may be a little late to start forcing some types of bulbs for this winter, but some bulbs are ready to go and need no advance planning! Here are some easy steps to getting your own beautiful indoor blooms.

Step #1 – Select Your Bulbs

Many bulbs require pre-chilling in order to grow indoors (35-40ºF is recommended – like in your refrigerator!). The catch here is that many ripening vegetables and fruits, especially apples, release ethylene gas, which can kill or damage the flowers, so if you store produce in your refrigerator, try a partially heated garage instead or use bulbs that do not require pre-chilling. Here are some suggestions for bulbs that work well for indoor forcing:

  • Amaryllis (requires no chilling)
  • Hyacinth (12-16 weeks of chilling)
  • Tulip and daffodil (12-16 weeks of chilling)
  • Crocus and grape hyacinth (12-14 weeks of chilling)
  • Paperwhite narcissus (Requires no chilling)
  • Autumn crocus or Colchicum autumnale (Requires no chilling)
  • Dutch Iris or Iris reticulata (Requires no chilling, but should be fed every 2 weeks)
  • Bluebells or Scilla (Requires no chilling)

Step #2 – Prepare Your Bulbs

There are several methods for growing bulbs indoors. Here are the most common:3d91d4169f8171f5f69d4648f30c4da9--amaryllis-bulbs-tulip-bulbs-in-a-vase

Pebbles & Water: Simply take a clear glass bowl, fill it with gravel or decorative stone. Firm the base of the pre-chilled bulbs into the pebbles until they stand firmly on their own. Next, fill water up to the base of the bulbs, but not high enough that it touches them (about 1/8 away). Keep it in a cool, dark location for a few weeks until they’re ready to bloom to help maintain strong stems and encourage root growth.

Water Forcing: There is an hourglass-shaped vase you can buy called a ‘Hyacinth Glass’. Simply fill the container with water, up to the tapered neck, set the pre-chilled bulb on the widened mouth of the container and it’s ready to grow. Again, do not let the bulb touch the water. Place bulbs in a dark, cool place for a few weeks before blooming.

Potting in Soil: Shallow pots are usually used for forcing, but you can use most anytp6kchcx1mts4wbeafa0 container, if it has holes for drainage. Fill the pot about 3/4 full with a peat based potting mix. Squeeze in as many bulbs as you can fit. You can use all one type or mix and match, but choose bulbs with a similar bloom time. Plant the bulbs flat side down and cover with potting mix. Leave the shoot tips poking out slightly above the soil line. Water until it comes out of the drainage holes. Next, chill the pot and all for the recommended time (above). You can do this by burying it in the ground outside, placing it in your garage, or in a refrigerator. When you bring the pot indoors, keep it in cooler temperatures for a few weeks until it’s ready to bloom.

Step #3 – After the Bloom

Unfortunately, forcing takes a lot out of a bulb so it may not bloom again for many seasons. Still, bulbs can be planted outside when the weather permits just as with any perennial. Do not remove the foliage until it has turned yellow. The bulbs should never be forced a second time, always start with new bulbs.

Have some fun this winter and give forcing a try!

Spring Bulbs

We’ve been blessed with some fairly warm weather for this late in the year, and I suddenly remembered that I haven’t put my bulbs into the ground yet! Project for tomorrow!

RX-DK-HTG04001_spring-bulbs_s4x3_lgFlowering bulbs are one of the brightest spots of spring when you live in the north and enjoy a long winter. Such a dazzling display arising from such homely beginnings is truly miraculous. A minimal amount of time, effort, and money in the fall is rewarded spring after spring with a spectacular tapestry of color, texture, and fragrance.

In addition to true bulbs (daffodils, tulips, hyacinths, and lilies), this plant category includes corms (crocuses and gladioli), tubers (begonias, anemones, and cyclamens), tuberous roots (dahlias and foxtail lilies), and rhizomes (irises and trilliums). When selecting bulbs, choose those that are big, firm, and plump — generally the bigger the bulb the bigger the bloom. Avoid bulbs that are soft or have moldy spots.flower-bulbs-494399_960_720

When planting, choose a spot with rich, sandy, well-drained soil that is easily viewed from your window and plant bulbs in abundance, en masse, and in natural free-form drifts. Prepare the ground by digging a wide trench and working in compost or leaf mold. A good rule of thumb is to plant the bulbs three times as deep as they are high. Remember that anything too studied looks artificial – then throw caution to the wind and toss a handful of bulbs up in the air. Plant them, root-end-down, wherever they land. This landscaping method is a great stress-buster, and you will be pleased with the results of your no-design-is-the-best strategy.

87701Or, use a bulb planter to make 6- to 8-inch holes for large bulbs, and 2- to 4-inch holes for smaller bulb species. Space small bulbs 3 to 4 inches apart and large bulbs 5 to 6 inches apart. Topdress with any commercial bulb fertilizer.

With either method, cover bulbs with top soil and water them thoroughly. In cold zones, bulbs can be left in the ground. In warm and temperate zones (where temperatures remain above 20ºF/6ºC), chill the bulbs in a brown paper bag in the refrigerator (away from fruit) for 8 to 10 weeks before planting.

Select bulbs with different bloom times for a show of color from late winter through summer. Left undisturbed, the bulbs will colonize and produce profusely for years to come.

Early bloomers: Snowdrops (Galanthus), Winter Aconites (Eranthus hyemalis), and Crocuses. Crocus tommasinianus, in Easter-egg shades of pale lavender and deep purple, is usually the first to appear (and the corms are squirrel-resistant).

Mid-season: Daffodils and Jonquils (Narcissus), Siberian squill (Scilla), Grape Hyacinth (Muscari)

Late spring: Tulips, tulips, tulips! Colors range from brilliant red to deep maroon, from snowy white to bright yellow, and from beautiful shades of orange to variegated varieties in all colors. Shapes include the scalloped parrot, the pointed lily, and the artistic fringed tulip. Extend your tulip time by growing varieties bred for early, mid, and late blooming.
