Place a tag where you have moved a plant since you may not remember that you put it there in the spring. Bulbs can be planted as you divide and transplant perennials. Consider the flowering time and colour of the perennial and plant a bulb which would be a good companion to that. Evening primrose, a rapid spreader in need of constant dividing, can be under-planted with crocus or daffodils to give an early flower show. The primrose leaves will then disguise the foliage of the bulbs after they have ceased flowering.
Ornamental onions are perfect companions to peony or artemisia.
It is very important to mow the grass short for the final cut of the year. Long grass will promote a disease call snow mould, as well asprovide a likely habitat for mice, voles or moles. The damaged caused by these rodents will appear as unsightly tunnels throughout the lawn in the spring. Daisy Moore, 1999.
