Growing Crocosmia

Luckily, Crocosmia plants are among those ornamental flowers that you do not have to think about much once you plant them in their new home. In fact, these stunning companions can basically take care of themselves with minimal effort on your part. As long as you provide them with environmental conditions that mimic their natural habitat, it will be almost impossible to hurt these low-demanding plants.

In general, your Coppertips will grow at their best if you are growing them under full sunlight exposure. These plants will become somewhat floppy in shaded locations. However, in regions with hot summer months, they will actually benefit from some afternoon shade.

Coppertips tend to strain towards the sun and, after a while, they will begin to grow a bit crooked. In case you notice this, you can dig your plants out of the soil then relocate them for optimal results. If you want to keep them indoors in pots, we recommend you rotate their containers occasionally to ensure straight growth.

When it comes to temperatures, Crocosmia plants are hardy in the USDA zones 5 to 9. While these flowers can withstand high heat and humidity, they will not do so well in drier climates with mild temperatures. If you live in a much cooler area, it is wise to grow your plants in pots and bring them inside in the fall.

Coppertips are typically pest- and disease-free when they are growing in proper conditions. Still, if your Coppertips experience poor soil drainage, they will become prone to pest infestations. The most common intruders that may bother your flowers are spider mites, especially during the dry summer months. You can get rid of these pests by misting your plants regularly until you stop to notice their presence.

Planting Crocosmia

Knowing how and when to plant Crocosmia species is vital for them to grow healthy and happy. As a general rule, you must plant your flowers in spring, but only after all danger of frost has passed. If you want to plant them in groups of 12 or more, make sure you space each specimen at 6 to 8 inches (15-20 cm) apart from the other ones. Near other species, we suggest you plant them at 18 to 24 inches (45-60) away.

In terms of growing medium, Coppertips can do just fine in a wide variety of soils. However, it is mandatory to plant your flowers in a fertile, hummus-rich substrate that comes along with very sharp drainage. If your garden soil is on the heavy clay side, you should grow your plants in pots or raised beds. For potted specimens, choose containers that have one or more drainage holes at the bottom.

Because Crocosmia plants can perform well in almost any type of soil, they do not usually require supplemental fertilizing. In fact, when these flowers receive too many nutrients, their foliage will overgrow at the expense of the bloomings.

During their flowering season, you can remove all spent blooms to make room for new, healthy ones to flourish. Once this period has ended, keep the leaves of your Coppertips so that the plants can give enough energy to the bulbs for the next year’s blooming. If some of the leaves begin to wither, however, you can simply cut their foliage back almost to ground level.

To avoid this unpleasant experience, make sure you always check their growing medium before watering them again. When the top layer of soil feels dry to the touch, you can safely provide your Coppertips with a nice, deep drink.

In spring, dig your flowers out of the soil, then cut their roots in two or three sections using a sharp garden tool. After this process, you can just transplant the tiny specimens in their permanent spots. You can also remove the small offsets from their bulbs with bare hands and plant them wherever you feel like it.

To propagate your Coppertips by seeds, you must first wait for the autumn to show its presence. During this season, you can collect the seeds from capsules and save them until next spring. Once the last sign of frost has passed, soak the seeds in water for a week or so before sowing, then plant them directly in the ground in sandy loam soil.
