A Detailed Guide to Selecting and Raising Lark's Tongue (Delphinium) Seeds

Lark's tongue, also called little larkspur, blooms with dense pale purple flowers that give an incomparably luxurious feel, and it is often used as a flowerbed flower. If you want to plant lark's tongue, the first step is buying seeds. So how do you select lark's tongue seeds? What seedling-raising methods are there? Let's find out together below.

How do you select lark's tongue seeds?

1. Purchasing channels

To buy lark's tongue seeds, go to a legitimate agricultural supply store, or a distributor of a legitimate seed company, or a legitimate flower and nursery stock market. When buying, look carefully, check whether there is a business license, whether the operator patiently explains the cultivation techniques and precautions for this variety, and whether an invoice can be provided. In addition, do not buy bulk seeds, and carefully check whether the packaging shows any signs of having been opened; at the same time, pay attention to information listed on the packaging bag or inner label, such as the variety name, approval number, production and operation license number, production date, and suitable regions.

2. Look at the price

Many unscrupulous traders "hang out a sheep's head but sell dog meat," selling the same variety at a "low" price. In fact, "there is no such thing as a free lunch"; the lark's tongue seeds they sell are either inferior or counterfeit. Once bought, you will definitely "lose more than you gain." Therefore, when buying, you must seriously think about "why is the price so low" before deciding whether to buy.

What seedling-raising methods are there for lark's tongue?

1. Sowing time

The best sowing times for lark's tongue are early September in autumn and March to early April in spring, while in regions that are warm all year round there is no seasonal restriction, and it can be sown as long as the temperature can be 15-22 degrees.

2. Seed treatment

Soak the seeds in warm water for 10-12 hours, then take out the seeds and let the moisture dry naturally; especially for purchased flower seeds, soaking until they swell and then sowing can increase the germination rate.

3. Seedling management

For the seedling-raising substrate, peat soil is recommended; it is loose and breathable and can increase the germination rate. When operating, first fill the seedling tray with the substrate and press it firm, which helps with later transplanting, then water the substrate with a 500-fold dilution of carbendazim to sterilize the soil. After the substrate is ready, use an ear pick or small plastic tweezers to place the seeds in the middle of the seedling tray, one seed per cell, then cover them with 0.2-0.5 cm of vermiculite. After sowing and raising the seedlings, use a spray bottle to moisten the vermiculite, cover with a transparent seedling tray lid or directly wrap with plastic wrap, and place it in a shaded, cool place at 15-22 degrees; it can sprout in at most two weeks.

4. Temporary planting and transplanting

After the seeds sprout, the lid can be removed, and then appropriately increase some scattered light. When the seedlings grow 2 pairs of leaves, temporary planting and transplanting can be carried out. For the temporary planting pot, a breathable plastic pot with a diameter of about 10 cm and many drainage holes is recommended. When transplanting, first lay a gauze net at the bottom of the pot, then fill it with an equal-proportion mixed substrate of peat and perlite, and you can mix in a tiny bit of slow-release fertilizer. After filling about 8 parts full and pressing firm, dig a small hole in the middle, and use a plastic seedling lifter to transplant the seedling together with its soil as a whole. Finally, continue filling with substrate, press lightly and firm, water thoroughly to settle the roots, place in a cool place for 3 days to recover, then move to a place with scattered light for care.
