Plant supports come in many shapes and sizes, from fancy willow cages and small trellises, to shiny metal canes. A simple and effective way that also blends in unobtrusively is to use pea sticks - small branches cut from any shrub or plant stuck into the ground around the plant to be supported. The new branches will grow up around and through the pea sticks and be supported gently without having to be individually tied in. Lawn care - you may need a slight trim at this time, but make it a gentle one with the mower settings as high as possible. They can be lowered later as growth gets more vigourous.
Lawns benefit from a raking to remove winter debris such as old leaves and moss.
Prune back stems of hellebores and primulas that have finished flowering. If you want the plants to set seed, leave one or two stems to finish maturing. This will tidy the area, save the plant some energy and prevent too many unwanted seedlings spreading around. Harvest rhubarb now by gripping stems firmly at the base and pulling away from the crown sharply. Try to remove any flowering stems completely.
