Tips for Planting Bulbs

FlowersBulbs480x174

No other types of plants will give the gardener more beauty, or a wider range of variety, color and flowering times than flowering bulbs. They produce flowers of incredible colors from one end of the growing season to the other. Nothing else will reward you with so much pleasure for so little effort…at least in your garden.

Plan ahead
Color and time of bloom are two of the most important elements to consider when planning your bulb and garden planting. It can be very helpful to make a sketch of your garden before planting. Consider which bulbs to plant and where based upon height, sunlight, color and blooming time. Remember, most of the bulbs you plant in fall are hardy and can remain undisturbed for years while most of the bulbs you plant in spring are tender and must be dug up and stored before cold weather sets in.

Soil prep
Good soil preparation is the first step to successful bulb gardening. Make sure the soil is loose and porous. Well-drained soil is a must or else bulbs will rot. The soil should be turned over and organic matter, peat moss or a bulb nutrient worked through to encourage root development.

How deep?
The depth of planting for bulbs depends on their size. A good rule of thumb is that the depth should be three times the diameter of the bulb. Small bulbs should be covered with 1-2-in. of soil while large bulbs should be planted 6-8-in. deep (see individual listings for specifics). In the South, plant large bulbs 2-in. shallower than the normal recommendations.

How far apart?
The spacing of bulbs depends largely on the effect you are trying to achieve. The most effective planting technique is to plant most bulbs in clumps rather than in individual lines. Space bulbs according to color with the softer colors in the front and the more vibrant in the background. Group bulbs according to height and in sequential bloom pattern for a long-lasting show of color.

After planting…
Cover bulbs with soil, water well and mulch with shredded leaves. In the spring, when the first shoots appear, remove the mulch and sprinkle again with bulb food. This encourages the flowering and helps rebuild the bulb for the next year.

If the weather is dry, water the bulbs during their growing period. When the flowers begin to fade and before a seed pod forms, cut the flower head…but be careful to leave the foliage to die back naturally.

Storing bulbs
Spring flowering bulbs do not have to be dug and stored in most Hardiness Zones. To store summer flowering bulbs, dig the bulbs when the foliage has withered or turned brown by a light frost. Air dry in a well-ventilated area for a week. Then remove all soil from the bulbs. Bulbs must be dried before storing or they will rot. Dust the bulbs with a fungicide and store in dry peat moss or wood shavings in a brown paper bag, open crate, netted bag or even old pantyhose. Store at 50-55-degrees in a dry location until time to replant.

Bulb Do’s and Don’ts

Some simple things to remember about bulbs:

ALWAYS plant bulbs in borders or beds with good drainage. Planting bulbs in well-drained soil is vital and the most important instruction we can give you.

DO NOT use any strong commercial fertilizer or fresh manure when planting bulbs.

ALWAYS cut as little foliage as possible when cutting flowers from your bulbous plants. The leaves and foliage are essential for storing food for next year’s blooming.

ALWAYS let the foliage die back on its own in the garden before trimming it back or digging up the bulbs. Do not trim back healthy green foliage or the bulb will not perform well next year.

NEVER dry bulbs in the sun, always in the shade in a well-ventilated area.

ALWAYS store bulbs in a dry, well-ventilated area to prevent mold or mildew. Do not store them in an air-tight container.

Bulbs in Bulk- When purchasing bulbs in bulk, check the quality to make sure the bulbs are firm and not moldy or squishy.

Full Sun- For most bulbs, choose a site that gets full sun, though most daffodils can tolerate part shade.

Good Soil- Make sure soil is rich in organic matter and well drained because bulbs are highly susceptible to rot.

Make Them Pop- Give bulbs a dark green backdrop, such as an evergreen hedge, for making their colors pop.

Plant in Masses- Plant bulbs en masse, not in small clusters, to create the biggest impact.

Sweeps of Color- Plant in sweeping drifts of color, not in uniform rows, for a bigger visual punch.

New Heights- Consider hillsides for taking advantage of varying heights of flowers, making a planting bed seem larger.

Color Block- For the boldest effect, plant in masses of one color — and one that complements adjacent plantings of spring annuals or blooming shrubs and trees.

Planting Bulbs- Save time – and your back – by placing bulbs, tip end up, on top of the planting bed, then cover them with a layer of several inches of soil, instead of digging individual holes for bulbs. Don’t worry if the bulbs tip over; they will work themselves upright.

Extend Growth- Extend the bulb bloom season by combining varieties that bloom early, mid- and late spring.

Contrasting Colors- Under plant beds of annuals, such as pansies or violas, with bulbs to create a complementary-color foil and extend the bloom season.

Mix Flowers- Combine container gardens of fall and winter annuals with bulbs for surprise additions next spring.

Avoid Mulch- Don’t mulch very heavily over bulb plantings because that layer of insulation withholds extra moisture in the soil and could cause bulbs to rot.
