Delphinium Requirements

Delphiniums grow equally well in both bright sunlight and shadier areas. Good air circulation will provide for optimal growing conditions, and help to prevent mildew. Well-drained soil is a must, since wet roots will destroy your plants. Taller varieties require staking. Soil that is heavy or poor quality should be aerated and amended with organic matter such as peat moss or compost.

Starting Your Seeds

Delphinium seeds can be started at almost any time, since they can be transplanted between April and September. During the winter and very early spring, delphinium can be started indoors. To guarantee blooms the first year, delphinium should be started in the winter and transplanted early in the year. Delphinium started outside once it gets warmer will bloom the following year.

Sowing Delphinium Seed

Seeds can be sown either inside or outside, once the weather is warmer. It’s important to not cover the seeds with more than 1/8 inch of soil that is damp, but not soaking wet. Water that is too wet will kill the seeds and cause root or seed rot in the seedlings. Delphinium seed is no long viable after one year, so always use fresh seeds. It can also be helpful to store the seeds in the freezer for two days before planting. Before transplanting, add a non-burning fertilizer to the soil you have prepared for best growing results.
