How to Grow Russell Lupins from Seed?
It is very simple to grow the Russell lupins. These perennials will thrive in areas where there is enough sunlight and a well drained soil. If you are planting a lupin from the seed, then you need to either soak the seeds in lukewarm water overnight or scratch the seed surface so that the seed coat can be easily penetrated. You can also chill the seeds of the lupin plant in the refrigerator for about a week before planting them in the soil. It can grow from seeds sown in early spring or even from the plant tubers. You can also plant Russell lupin seeds during the autumn season so that the chilling needed for the seed can be provided by Mother Nature itself. With quality care the lupin plants will produce new seeds that will finally re-produce more flowers in the following season.
If you want to enjoy more Russell Lupin blooms, then you need to give the lupins plant food that is rich in phosphorus. The growth of the foliage can be enhanced by using nitrogen rich fertiliser. The spent blooms need to be deadheaded to encourage more lupin flowers. The spent spikes also need to be pruned to ensure strong plant growth. The propagation of the plant is from the seeds or cuttings or by division that has to be done in early spring. The seedlings of the plant need to be planted in the soil when it is small as it does not like root disturbance when it grows.
- In order to encourage side shoots, you need to cut back the flowers that fade to the next bud. They normally bloom during early spring and last till midsummer.
- To prevent seed pods from developing, you should cut away the stems of the flowers of the plant’s basal foliage.
- If you find white insects on the flowers, leaves or stem, then prune them off immediately.
