No matter how careful you are about moving the plants around your garden you must keep in mind that they were taken out of the ground.
After being removed from their environment the plants enter a state of shock, state determined by the way we manipulate them. Because of that they need special attention.
The replanted plants must have sufficient quantity of water; otherwise they will die for sure. The flower roots will suffer some damage during replanting. That is unavoidable; so you must be aware that the plants will need to work and replace them.
This means that for a week or two after replanting the plants must be watered moderately and the soil must be maintained moist but not muddy. The water excess will drown the already weakened plants.
Under no circumstances should you apply fertilizer on the transplanted plants. The plants should not come in contact with fertilizers at least a few weeks because the damaged roots will grow better with only the natural feeding inside the new bed.
When you replant tall plants, the types of Delphinium, it is better to tie them to a support. By doing this you will help the plant to sustain the flowers during the blooming period.
The best way to discover whether the replanting was successful is to look for signs of new leaves. When the roots have recovered, most of the plants will shed the old leaves while creating new ones. The process is a sign that the plant is back to its natural course and enjoys the habitat.
Of course, after the replanting proved successful there are a few steps which should be followed regularly. You should water the plant so the soil benefits from a continuous humidity. The first week is crucial; so make a note in your agenda to verify the bed everyday.
Remove the buds or flowers if the replanted plant has any. This will make the plants redirect energy to attend the roots. Cover the bed with sawdust to maintain humidity and prevent the intrusion of unwanted weeds.
If the replanting takes place in the hot season, try and shade the plants during the hottest hours of the day. Strong sun rays can damage the feeble plants and the best way to protect the plants is to keep them away from a too concentrated UV exposure.
Two weeks after the plants regain their strength you can try a mild fertilization.
