How to Grow Larkspur? Detailed Guide to Cultivation Methods and Precautions

Today, the editor will talk about larkspur. Larkspur, also known as pigeon flower. With brilliant colors, alternating purple and white, and a very unique flower shape, it is deeply loved by people. Most people like flowers with beautiful appearances and want to grow some larkspur at home. So, how should larkspur be cultivated? What needs attention? Let's take a deeper look together with the editor!

How to Grow Larkspur

1. Sowing

Larkspur can be sown in both spring and autumn. If sown in autumn, it must be done in mid-September. If sown in spring, the flowering period is in September; if sown in autumn, the flowering period is in May of the following year. For flowers sown in spring, the timing should be estimated to avoid blooming during the scorching heat of midsummer.

2. Repotting and Care

When larkspur grows 2 true leaves, it needs to be transplanted with soil into a small pot, and after the seedling grows larger, it should be repotted 1 more time. Because larkspur has few roots, extra care is needed when repotting to avoid damaging the root system, which can cause slow growth or even death of the plant. After sowing larkspur, the soil must be kept moist. The simplest method is to cover it with some grass, and gradually remove the covering after the seedlings emerge.

3. Water and Fertilizer Management

Watering larkspur should follow the principle of watering when dry and stopping when wet, keeping the soil moist but avoiding waterlogging. During the flowering period, water appropriately more to avoid the soil becoming too dry, which can cause poor flower form. Fertilizing: during the growing period, apply fertilizer once every half month to larkspur, and add 2-3 applications of phosphorus and potassium fertilizer before flowering. Keeping the soil moist during the flowering period of larkspur can prolong the viewing period of the flowers. According to the growth condition of larkspur, apply cake fertilizer water 1-3 times per month.

4. Light

Larkspur likes light. Full-sun care helps promote flowering, prevents the plant from becoming leggy, and keeps the plant shape compact and attractive.

5. Height Control

After repotting larkspur, paclobutrazol can be used to control plant height. The specific method is: apply 0.5% paclobutrazol once every 2 weeks.

Larkspur Cultivation Methods and Precautions

I. Larkspur Cultivation Methods

1. Light

It needs light, so usually let it get some sun, and in October let lights illuminate it, so it will bloom a bit earlier.

2. Watering

Watering also has requirements; it needs alternating dry and wet conditions. If it is during the flowering season, it can be watered a bit more.

3. Fertilizing

When repotting, some fertilizer needs to be applied, such as dry manure. After that, depending on the growth condition, apply cake fertilizer water about 1 to 3 times per month. Before flowering, nitrogen fertilizer can be applied, but after flowering, more phosphorus and potassium fertilizer must be applied. When fertilizing, water moderately.

II. Larkspur Cultivation Precautions

1. Care

After sowing it, what we need to do is keep the soil moist. It is best to cover it with some grass, then wait for the seedlings to grow and gradually remove the covering.

2. Transplanting

If it is to be moved into a pot, first make sure it has grown two leaves. At this time, a relatively small pot is fine, and when it grows larger, it can be changed to a larger one.

3. Height Control

It is not a good thing if it grows too tall. At this time, we can use paclobutrazol to stabilize its height. Generally, apply it about twice a month, with a concentration of 0.5% each time.

4. Diseases

It has some common diseases, such as black spot and chrysanthemum leaf blight nematode disease, etc. These can be treated with some reagents.

5. Pests

It can also suffer damage from some aphids or noctuid moths. At this time, deltamethrin EC can be used.

What Are the Propagation Methods of Larkspur

1. Larkspur Propagation Method: Sowing

The suitable germination temperature for larkspur is about 15°C, and the soil temperature is best below 20°C. It sprouts in about two weeks. Autumn sowing is from late August to early September. First sow in an open-field seedling bed, and before winter enter a cold frame or cold room to overwinter, then plant out in warm spring. In the south, direct sowing in open fields in early spring, with thinning to maintain a plant spacing of 25~5 cm. In the north, seedlings are generally raised in advance, planted out in mid-April, transplanted when there are 2~4 true leaves, and planted out when there are 4~7 true leaves. Pay attention to drainage on rainy days. After sowing, the soil must be kept moist. The simplest method is to cover it with some grass, and gradually remove the covering after the seedlings emerge.

2. Larkspur Propagation Method: Cuttage

Larkspur cuttage propagation is carried out in spring. When new branches grow more than 15 cm, cut cuttings and insert them into sandy soil. After inserting into sandy soil, do not rush to water; after 2-3 days, water appropriately.

3. Larkspur Propagation Method: Division

It can be done in both spring and autumn. In spring, divide when new buds grow to 15-18 cm, and transplant after rooting. Alternatively, after flowering, take new branches from the base for cuttage. Division depends on fate: some larkspur does not grow new buds for 3 years, while some larkspur grows many small seedlings in 1 year clinging to the base of the mother plant. Division is generally carried out once every 2-3 years, otherwise it easily consumes the mother plant's vitality. Mother's Day has just passed, so let us also give the larkspur mother plant more care and let her spend more time with her children, so that after the children become independent, their posture will be sturdy!

When to Sow Larkspur Seeds

1. Larkspur can be sown in batches, so its flowers can be seen often. When sowing larkspur, it can generally be sown in both spring and autumn. However, in places where summer temperatures are relatively high, sowing needs to avoid the summer heat.

2. Basically, when sowing larkspur, seedlings need to be raised in advance. Start sowing in late August. By October, the larkspur seeds will germinate and grow, and produce 2——4 true leaves, at which point they can be transplanted. In winter, attention should be paid to keeping warm and supplementing light. By March of the following year, they can be planted out. In this way, larkspur can bloom from May——July.

Friends who like growing flowers, do you understand now? Before growing larkspur, we must first understand its living habits and propagation methods. During the cultivation process, we should also consider problems from many aspects, so that we can grow satisfactory flowers.
