| Sowing, Seeds, Planting | Delphiniums love well-drained soil, but are hungry feeders. This means adding plenty of grit on heavy soils to help with drainage, if they sit wet in their dormant winter season, they can die, so make sure you prevent this. To aid quick establishment, sprinkle mycorrhizal fungi (Rootgrow) into the base of the planting hole. Add plenty of organic matter added to their planting holes when they first go in and to aid quick establishment, sprinkle mycorrhizal fungi (Rootgrow) into the base of the planting hole. Correct spacing is also important to help avoid mildew. |
| Care Tips | Feed regularly throughout their growing season. You want to use something slow release such as organic chicken manure pellets. Do this a couple of times in summer and try to repeat once in autumn before the plants die down. The other vital thing with delphiniums is the staking as any strong wind or heavy rain will flatten them and break their hollow stems. Cut flower spikes and leaves right to the ground in July and they will leaf up and flower again in August and September. Unfortunately slugs love delphinium shoots, so a dose of Nemaslug will help protect your plants. |
