  • Improve poor soils with garden compost and fish, blood and bonefertiliser.
     
  • Hydrangea paniculata ‘Limelight’ will grow well on alkaline oracidic soils unless they are extreme
     
  • April to May or mid September to October are the best times to planthydrangeas. Make sure they are well watered.
     
  • The best position is one which receives sun in the morning and lateafternoon, however this particular variety will tolerate full sun verywell.
     
  • Dig a hole twice the width of the rootball. Sprinkle in a handful of
    blood, fish and boneand work into the ground.
     
  • Place the plant into the hole.

CARE OF HYDRANGEA PANICULATA ‘LIMELIGHT’

Each spring apply a mulcharound the plant to lock in moisture and provide a wide range of low levelnutrients as the mulch rots down.

Each spring and autumn scatter a couple of handfuls of
fish, blood and bonearound the shrub and work it in gently with a trowel.

There are more expensive fertilisers but this one is very cheap andideal. It provides nutrients over a long period of time and avoids releasingtoo much nitrogen. Do not apply a nitrogen rich plant fertiliser, it willencourage weak stems and foliage at the expense of flowers.

Although this shrub will tolerate drought it will reduce its floweringability. It’s best to water the plant well in summer during extended dryperiods or where the soil drains very easily.

HOW TO PRUNE HYDRANGEA PANICULATA ‘LIMELIGHT’

Your Hydrangea paniculata ‘Limelight’ can be pruned in two ways. The firstis to simply cut off all dead flower heads to just above a healthy set ofbuds. After four to five years this will result in a shrub which will be3.5m / 11ft in height and spread.

Most gardeners however prefer to keep this shrub to a more manageable 2m /6ft 6in which results in the best display of flowers. Prune as follows toachieve this:

  • Prune during mid March in warmer parts of the UK to mid April incooler areas.
     
  • Prune back stems to four buds above the base of the shrub. Thissounds quite harsh but it will bounce back with vigour.
     
  • Cut out, as low as possible, any diseased or damaged stems.

     
  • Feed with two handfuls of fish, blood and bone and apply a mulch asdescribed in the previous section.
