If you’re looking to add some color to your garden or simply want to brighten up your home with some fresh flowers, planting gladiolus bulbs is a great way to do it. With their tall, showy spikes of flowers in a variety of colors, gladiolus bulbs are a popular choice for gardeners and flower enthusiasts alike. In this article, we’ll go over everything you need to know about how to plant gladiolus bulbs.

Choosing Your Gladiolus Bulbs

Before you can start planting your gladiolus bulbs, you’ll need to choose the right ones. When selecting your bulbs, look for ones that are firm and plump. Avoid bulbs that are soft, moldy, or have any signs of damage. You’ll also want to choose bulbs that are large enough to produce a good-sized flower spike.

When to Plant Gladiolus Bulbs

The best time to plant gladiolus bulbs is in the spring, after any danger of frost has passed. In most areas, this will be sometime in late April or early May. If you live in a warmer climate, you may be able to plant your bulbs as early as March.

Where to Plant Gladiolus Bulbs

When choosing a location to plant your gladiolus bulbs, look for a spot that gets full sun for most of the day. The soil should be well-draining, as gladiolus bulbs don’t do well in soggy soil. If your soil is heavy or clay-like, you can amend it with some compost or peat moss to improve drainage.

How to Plant Gladiolus Bulbs

To plant your gladiolus bulbs, dig a hole that’s about six inches deep and six inches wide. Place the bulb in the hole with the pointed end facing up, and cover it with soil. Space your bulbs about six inches apart to give them room to grow.

Caring for Your Gladiolus Bulbs

Once you’ve planted your gladiolus bulbs, there are a few things you’ll need to do to care for them.


During the growing season, your gladiolus bulbs will need regular watering. Aim to keep the soil moist, but not waterlogged. If you’re not sure if your bulbs need water, stick your finger into the soil to check – if it feels dry, it’s time to water.


To help your gladiolus bulbs grow strong and healthy, you can fertilize them once a month during the growing season. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.


As your gladiolus plants grow taller, they may need some support to keep them from falling over. You can use stakes or bamboo poles to prop them up.
