Tips for Keeping Your Plants Healthy
- Globe thistles are relatively carefree plants, but there are a few things you can do to keep them looking their best.
- First, make sure they’re planted in well-drained soil. If your soil is heavy or compacted, consider amending it with some sand or organic matter before planting.
- Once they’re established, globe thistles are drought tolerant; however, they’ll produce more flowers if given regular water during extended periods of dry weather.
- If you live in an area where deer are a problem, rest assured that globe thistles are one of the few plants they’re not likely to eat.
Lighting and Temperature
Globe thistles prefer full sun, but they’ll tolerate partial shade. If you live in a hot climate, planting them in an area that gets some afternoon shade will help prevent the leaves from scorching.
As long as the soil is well-drained, globe thistles aren’t picky. In fact, they’ll even grow in sandy or rocky soil.
Fertilizing isn’t necessary, but if you want to give your plants a boost, use a slow-release fertilizer formulated for perennials in early spring.
To keep your globe thistles from getting too leggy, cut them back by a third in late spring. This will also encourage bushier growth.
During the first growing season, water your globe thistles regularly to help them establish deep, extensive root systems.
Once they’re established, they’re drought tolerant; however, they’ll produce more flowers if given regular water during extended periods of dry weather.
Globe thistles can reach up to five feet tall and four feet wide.
Globe thistles produce blue, purple, or white spherical flowers that bloom from summer to fall.
Common Pests & Plant Diseases
As any gardener knows, maintaining a healthy crop is essential to protecting against pests and diseases. However, even the most well-tended plants can be susceptible to infestations if conditions are ideal for pests.
Globe thistles are particularly susceptible to Aphids and four-lined plant bugs, which can cause damage to the plant without killing it.
The best way to reduce the population of these pests is to blast them with a garden hose, repeating the procedure multiple times. This will help to dry out the soil, which is ideal for these types of pests.
Crown rot is another type of fungus that can spread in humid conditions, but it is less common and can be eradicated by drying out the soil.
By taking these simple steps, gardeners can protect their globe thistle crop from pests and diseases.
Propagating Globe Thistle
Globe thistles are beautiful, spiky flowers that make a great addition to any garden. These striking plants are also relatively easy to care for and can be multiplied by division.
Divide globe thistle in the spring by digging up the entire plant and removing the taproot. Next, place the plant upside-down in the garden so that the roots are exposed.
Sterilize a sharp knife with alcohol wipes and then use it to slice a portion of the taproot. The plant should be divided into two halves, with a portion of the taproot, lateral roots, and above-ground development on each side.
Make a new hole for each half of the plant, being sure to replant at the same depth that it was originally growing.
Water well and fertilize monthly. You won’t be able to see new plants at the base until the plant is at least three years old, so wait until then to divide globe thistle again or give it away to friends.
Types of Globe Thistle
Globe thistle comes in a wide variety of cultivars, providing gardeners with a wide range of color options to choose from. One popular combination is to pair yellow flowers or rudbeckia with green globes of one variety.

When the weather warms and all danger of frost has passed, transplant the globe thistles into the garden. Give them plenty of room to grow, as they can spread up to 4 feet wide.
Once established, globe thistles are quite drought tolerant. Pinch back the tips of young plants to encourage bushiness. Globe thistle blooms appear in summer and last into fall.
