Handy Tips

Question: Should I use fertilizer when planting new trees?

Answer: No fertiliser or manure is to be mixed with the soil at planting, as this may cause root damage. Apply fertiliser to the soil surface and water in. Use compost instead of manure.

Fertilize your tree in spring and autumn. Slow release general garden fertiliser or Nitrophoska Blue is recommended. Rates of application vary according to the tree size and ground area to cover. Only apply fertiliser as per manufacturer’s instructions.

Question: How big should the hole be?

Answer: Dig a hole twice the size of tree’s container, removing clay into a separate pile. Keep sides of hole straight & bottom of hole flat.  If soil in hole is dry, soak with water before planting. Backfill the hole with good soil or compost. Finished height for the root ball should be flush with existing ground level.

Question: When and how do I best mulch the garden?

Answer: Mulch gardens to retain moisture at dry times of the year.  This is especially applicable in Christchurch and other areas of New Zealand that have watering restrictions.

Use pea straw, bark mulch or even old newspapers (several layers) and then cover with old compost or bark.
