When Should I Plant My Perennial Bulbs?

What is a perennial bulb?

A perennial is a type of bulb that blooms again over several years. Crocuses and daffodils are two excellent examples. It is a plant that returns year after year.

Fall is a common time for planting perennial bulbs for subsequent growth in the spring. Perennials grown in containers can be planted at any time of year.

However, they are often established in the spring, summer, and early fall. Most gardeners blend annual and perennial plants due to the shorter blooming times of perennials.

Annuals die quickly in the garden, but perennials keep giving year after year. They are less expensive than trees and shrubs, and you can easily grow them in large quantities throughout a variety of settings, including as focal points in garden beds, in pots and window boxes, alongside shrubs and trees, and in combination with annuals.

Perennials also grow larger year after year, allowing you to divide and replant them in different flowerbed areas.

When Is Too Late to Plant Perennial Bulbs?

Planting perennial bulbs at the correct dates is the key to a successful harvest. It will take some time for the bulbs to establish themselves. However, difficulties with diseases and fungi can arise if you plant your bulbs too soon.

For optimal results, wait until the average overnight temperature in your area is between 40 and 50 degrees before planting bulbs. When that happens, the soil is at the ideal temperature and revitalized for tucking bulbs underground for the winter.

Plant in September or October in the north because of the cooler weather. December is an excellent month to plant bulbs in warmer conditions.

Don’t put off planting your bulbs until spring or fall if you miss the prime window. A bulb is not the same as a seed. They can’t live above ground for very long.

If you come across a bag of daffodils or tulips in January or February that has yet to be planted, go ahead and take a chance and put them in the ground. They’d be better off putting it in the ground or a cool planting pot than letting it rot in the pantry or garage.

Bulbs intended for flowers are hardy by design. There are always unbelievable tales of bulbs blooming despite being put in the worst places at the worst times.

How deep do you plant perennial bulbs?

Your preparation of the soil is complete. The moment to inquire about bulb planting depth has arrived. The size of the bulb is the most important factor in determining the planting depth.

In general, the planting depth for perennial bulbs should be two to three times their length. Consequently, a tulip bulb, which is huge in comparison to a grape hyacinth bulb, will be set deeper into the ground. Plant your one-inch-long bulbs about three inches underground. That is, gauge the depth of the bulb below ground level.

It’s essential to plant bulbs at the correct depth if you want to see blossoms when the time comes. If you plant your bulbs too deeply, they may send up leaves instead of flowers.

However, if you plant the bulbs too shallowly, squirrels, who enjoy a healthy meal of freshly dug bulbs, are more likely to accidentally dig them up and eat them.

Typical planting depths for these popular perennials:

Daffodils

Daffodils not only have some of the brightest springtime hues but are also exceptionally pest-resistant. Put them in the ground at 6 inches deep.

Lilies

In the springtime garden, lilies stand out as wonderful, spectacular flowers. Depending on the size of the bulb, plant them anywhere from 6 to 8 inches deep.

Irises

Irises are one of the most eye-catching flowering plants due to their distinctive blooms. Irises are developed from rhizomes rather than bulbs and are best planted at the soil’s surface. This makes them a unique plant to cultivate.

Hyacinths

Hyacinths produce beautiful, colorful flower plumes. Put them in the ground between 6 and 8 inches deep. However, planting grape hyacinths 3 to 4 inches deep would be best.

Gladiolus

The gladiolus is a traditional late-spring flower and a great option for flower arrangements. You should plant the corms of these plants between 4 and 6 inches underground.

How long does it take for perennial bulbs to grow?

Bulbs are a terrific choice if you want to make your home look more attractive right away. Depending on your preferences, you may choose from a wide range of sizes and colors while shopping for these beautiful plants.

Additionally, bulbs mature rapidly, typically appearing in stores only 8 to 12 weeks after planting. So hurry up and put in some work, and you’ll soon be able to admire your bloom.

Planting perennial bulbs can be used for a variety of purposes around the house and garden. They vary in size, color, and shape, and each has its own distinct life cycle. You can harvest them after they bloom.

Depending on the bulb type and the surrounding area’s temperature, this can take anything from a few weeks to many months. You can plant them in your garden after harvesting them or bring them inside to enjoy as ornamental plants.

Will perennial bulbs bloom in the first year?

Many amateur gardeners don’t try growing perennials from bulbs for fear of wasting a year’s work. Some perennials are like this, but the ones on this list will reward you by blooming the same year if you start them from bulbs early.

Some perennials take only a couple of months to bloom from the bulb, making them competitive with annuals.

Easy to care for and typically blooming the year after being planted in the fall, perennials are an excellent choice for the home garden.

As their foliage dies back after flowering, you can hide it by planting them 4 to 5 inches beneath the soil line in a border next to other perennials.

How often should I water perennial bulbs?

When planting bulbs, it is important to water them thoroughly so that the soil settles and no air pockets form around the roots.

After the buds have appeared in the spring, water the bulbs if the soil is still dry. As long as the plant is in bloom, water it once a week using a soaker hose to avoid getting water on the leaves.

Your ability to keep your plants flourishing, healthy, and happy depends on your familiarity with their watering requirements. To ensure that water reaches the plant’s roots, it is best to water less frequently but more thoroughly. This will give the plant time to develop deeper, healthier roots, producing a healthier, more robust plant.

Tips

  • After the first frost, prune the perennial and let it rest for the winter. Unless you live in an area with a very dry winter, you shouldn’t have to water it again until the following spring.
  • When you water new perennials, you often waste more water than when you water older plants with deeper roots.
  • During the growing season, you should plan to water frequently.
  • Be sure to give your newly planted perennial plenty of water to help it thrive.

Conclusion

Your ability to keep your plants healthy and thriving depends on your familiarity with their watering needs. If you plant them too deeply, you won’t get any blossoms. The bulbs can be dug out and replanted at the proper depth the following year.
