Here is some information about how to look after you Hazelnuts during the year 


With May almost over and winter fast approaching we are entering our busy season in the nursery and orchard, with this years tree orders preparing to leave and next years stock being propagated as well as our orchard maintenance to see to.

By this stage nuts are safely off the ground and autumn fertilisers are down, leaves are turning and catkins/flowers partly developed.

winter frostIf you are planning to plant a new orchard or extend an existing one this is the time to begin preparation. Hopefully you will have already ordered your trees for this season and will be marking and ripping your rows ready for hole digging and planting when your new trees are delivered.

If your wind breaks are not yet well developed we would suggest the use of individual tree guards, these will help young trees establish without wind stress and have the added advantage of protection from hares and rabbits.

Winter tasks for existing orchards should include a visual check for enlarged buds that may indicate big bud mite, one of the few insect pests hazels are prone to in New Zealand at the moment. Infected buds are easily removed and burned as a means of control. A winter spray with either Kocide and horticultural oil or Mancocide will help control insect pests, bacterial and fungal diseases.

Shaping your orchard trees to a single stem and vase shaped branches in the first few years of growth will aid management later on. Side trimming wind break trees will keep them in shape and encourage bushy growth without encroaching on your orchard space.

The work that you do now will prepare your trees for the next seasons growth and a regular maintenance programme will make future management much easier and more productive.

Flowering and pollination should be completed now and your trees will be producing young tender growth. It is at this time of year that wind protection is most important as young leaves are easily windburnt.

FlowersKeep up with orchard mowing and weed control as it can otherwise become a very big job!

Check your irrigation system thoroughly before you need it in the summer. Blockages can easily go unnoticed and cause problems later.

Many orchards will benefit from an application of a balanced fertilizer around the drip line of the tree base at this time. Spray with Kocide or Mancocide prior to bud burst.

Hazelnut Tree

You should notice small nutlets forming on your trees, at this stage they are green and camouflaged by surrounding leaves. Irrigation through summer will be required if you want your trees to develop strong growth and good sized nuts.

Sucker control either by clipping or a contact herbicide will be required once through the season. Leaf and soil analysis can be done around February 2-3 yearly through a reputable horticultural advisor and laboratory who will provide you with fertiliser recommendations for your property.

Nuts will ripen and drop to the ground when ready over a six week period. They will need to be collected either by hand, a vacuum system or a roller system.

After harvest is a good time to apply another application of fertiliser.

Continue irrigation into autumn if you are in an area which has experienced a dry summer. Spray with Kocide or Mancocide prior to leaf fall.
