How to grow sea holly (celery)? Planting methods and attentive problems of sea holly

Marine holly (thorn head) can adapt to drying and salinity. Special attention needs to be paid in cold and humid areas in winter. Next, let's take a look at the breeding methods and key points of sea holly.

Hyholi plants have green or silver-blue stems. Leaves can be long and thin, look small, shallow, or even round. It all depends on the variety. These flowers are unique, with silver, white, green or blue-purple bracts "collar" green or blue cones. The color usually looks almost metallic and changes in the sun.

Growth

Most sea holly species are reliable perennials in USDA Cold hardened Zone 4-9. More sunlight is beneficial to the growth and flowering of marine holly. Plants become soft in the cool shade.

Generally small varieties of sea holly grow to 15-60 cm high. Giant sea holly can grow to more than 1 meter tall. The giant sea holly is also known as the ghost of Miss Wilmot because of its shaded color. It is named after Ellen Wilmot, an English gardener.

Flowering

It begins in summer and will last until autumn. Frequent dead branches of flowers will prolong their flowering time.

Some skills to make more flowers bloom

Soil: sea holly has no special requirements for soil pH value. Anything that surrounds the neutral range will be fine. However, these plants need good drainage, or they will die. Sea holly has a long root. This makes it very drought-resistant, but it also means that it gets water from the depths of the soil, while surface moisture will only rot the crown.

Start with seeds: most marine holly varieties can start with seeds. If they layer first, they will do the best. The easiest way is to sow seeds directly in autumn and then wait patiently for spring to sprout. But if you freeze them in the refrigerator for about 4 weeks and then remove them to germinate within 2-3 weeks, you can start the sea holly seeds indoors.

Reproduction: because the sea holly has a leading root, it is not easy to split. But you can take root in the spring.

Planting: sea holly is easy to transplant seedlings, but becomes more difficult as plants mature, which is why they are not seen in plant nurseries. If you want to move planting, do it as soon as possible.

Fertilizer and water treatment

Water: once established, sea holly is very drought-resistant and does not need extra water unless it is subjected to a long period of heat and drought.

Fertilizer: do not require much fertilizer, so make sure you have a lot of organic matter in your soil. If not, you need to compost in the middle of the season.

Maintenance: after blooming, sea holly will bloom longer, but they grow beautifully in winter, so autumn flowers stay on the stem.

Pests and problems

The problem of sea holly is usually caused by moist conditions in the soil or air.

Slugs are the only insects of sea holly. If your plant is in a dry, sunny place, it won't be a problem.

Sea holly is prone to root rot and powdery mildew. Rotting roots can be controlled if you have well drained soil. Powdery mildew is hard to control, but you can try baking soda spray.
