Daifen Plant Care

Delphinium has some specific care requirements to meet. Once the ideal growth conditions are provided for them, this perennial plant will get cut flower rewards from the garden at least in the next 2-3 years!

Sunshine and temperature

Delphinium flowers need sufficient sunlight, at least 6-8 hours a day. In hot and dry areas in summer, this plant can benefit from light shadows in the hottest afternoon of the day.

Delphinium performs best in USDA planting areas 3-7 because they prefer not too hot and not too cold weather, and they prefer temperatures of 70-75 degrees Fahrenheit. The flower heads are frost tender and will wither in the winter garden. They can be cut back to the ground, and this perennial plant will come back in spring.

Water and humidity

The ideal time to water Delphinium is in the morning or late afternoon after the heat of the day has passed. They need at least 1-2 inches of water a week. They are a little drought tolerant, but can't stand long time without water, especially in the high temperature period, when they are planted in sufficient sunlight.

It is best to water Delphinium plants at the bottom to help keep the leaves dry and avoid possible fungal problems. Soaking hoses or drip lines at the bottom of plants can help you achieve this easily. Once the flower stems die and the plants are sown in early autumn, you can stop watering. In spring, when seedlings appear, watering will be resumed again.


Delphinium flowers perform best when they are planted in well drained soil. They prefer a light loam mixture of fertile soil. Adding compost to the soil during planting can help increase drainage of poor or heavy soil. Delphinium can survive in neutral soil, but prefers slightly acidic soil with pH range of 6.5-7.

Fertilize plants

As mentioned above, Delphinium benefits from adding compost or other organic substances to help increase drainage, which can be used as fertilizer for these heavy feeders. Yellowing leaves or slow growth usually indicate that plants need more fertilizer.

If you want to give them extra lift, add 10-10-10-10 balanced liquid fertilizer every 2 to 3 weeks throughout the flowering season. Fertilizing will help ensure that you make the most of your flowers.

Pruning parrot plants

Although this is not absolutely necessary, many gardeners choose to prune their flowers to prolong their flowering time. Twigs after flowering of main panicle. This can be achieved by cutting the main stem to the lateral buds to encourage them to bloom.

As the parrot flower has a columnar upright growth habit of high panicles, it may also need to place piles at this stage. They can grow up to several feet high and can easily be blown down by strong winds without some support.

Molybdenum plant propagation

Flowers will self sow year after year and become perennial plants in the garden. However, these seedlings are rarely true types - meaning that the seed may not produce flowers of the same color or type as the parent plant.

Many popular Delphinium are hybrids, which lead to instability of their offspring. If you want to better control which Delphinium appears in the garden, it is your best choice to start from seeds indoors.

Sow delphinium seeds 8-10 weeks before the last frost. These seeds need a period of time to germinate, ranging from 21 to 28 days. In order to obtain the highest germination results, a period of cold stratification is required. Put the seeds in the refrigerator for 2 weeks before planting.

Once all the frost threats in spring are over and the temperature at night is reliably above 50 degrees, you can transplant delphinium flowers into the garden. Dig a hole twice the diameter of the root ball and bury it in the same depth as the original pot. Keep watering well until your seedlings are set up.

Troubleshooting of manganese plant

Unfortunately, dogwood flowers may be full of pests and diseases. Fortunately, there are some very simple precautions that can keep your Delphinium plants healthy and happy.

The most common problem in planting eleocharis tuberosa flowers occurs when the seeds have not gone through an appropriate cold stratification period. This is especially important in warm climates.

Cyclamen mites are translucent, very small, and invisible to the naked eye, so they can only be identified before their damage is visible. They thrive in warm and humid environments, so they are common in greenhouses. Their damage will cause new growth to sag, twist or blister, and the appearance will be moist.

These mites can be killed by immersion in 110 degrees Fahrenheit water. This should not kill plants, but it will kill mites. A good precaution is to keep the humidity level low. For this reason, madder is grown in warm areas where the weather is dry.

Slugs and snails can also be a problem in humid environments. The damage of slugs and snails will show up as large holes in the leaves of plants. You may even see traces of mucus near Delphinium plants. Slugs and snails are particularly active in early spring before other insects become active.

Snail bait and slug bait made of iron phosphate are selected and can be safely used around wild animals and pets. Snail traps can also be made by burying a glass or a can of beer on the ground. Snails and slugs are attracted by it, fall in, and then cannot climb back.


Powdery mildew, southern blight, bacterial and fungal spots, mold, crown and root rot, white rot, rust, white and black head disease and leaf smut disease are all bacterial and fungal problems caused or aggravated by excessive water and humidity.

Provide good air circulation for your plants and keep the area around the flowers free of plant materials and debris to help prevent these problems. Most fungal problems can be treated with copper fungicides, although success varies, and it is usually best to remove infected plant material before it spreads.
