Look, I am not going to pretend I have got this all figured out. Avocados are weird plants. Beautiful, delicious, but weird. I have killed one already. Learned some stuff though. Hopefully, you can learn from my mistakes instead of making your own.
If you are shopping around for trees, The Plant Company has a solid selection of avocado varieties grown specifically for NZ conditions. They are one of those places that actually tests things locally. I was browsing their fruit trees NZ range last week – Hass, Reed, the good stuff. All grafted too, which matters more than people realise.
Where Can You Actually Grow Them?
Avocados are picky about location. They love warmth. Northland, Auckland, Bay of Plenty, Gisborne, Hawkes Bay, these are prime avocado territory. Nelson and Golden Bay work too. Further south gets trickier. Frost is enemy number one. Young trees will die if you don’t protect them. I learned this the hard way. One cold night, and that is it. Game over.
That Whole Flower Situation
Avocado flowers are honestly bizarre. They open as female at certain times, male at other times. Type A varieties like Hass and Reed open female in the morning. Type B, like Fuerte and Bacon open female in the afternoon. Plant one of each, and pollination goes crazy. They don’t even need to be right next to each other. Just somewhere in the general area. Bees handle the rest.
Planting Without Regrets
You must get this bit right.
- Full sun. All day, if possible
- Shelter from wind. They hate wind
- Soil must drain fast. Root rot kills them
Dig a hole twice the root-ball size. Mix compost and fertiliser. Add gypsum for clay. Mound if drainage is poor.
Spring planting is best. August through October. Gently loosen roots they are sensitive little things. Backfill the water well with seaweed tonic to help them settle.
Looking After Your Tree
The first year is about survival. Let it settle in.
- Water deeply twice weekly, not shallow daily sips
- Feed monthly, spring and summer with citrus and fruit fertiliser
- Mulch to protect shallow roots
- Frost cloth over young trees in winter
Start proper feeding after twelve months. Before that, they are still establishing.
How Long till Avocados?
Grafted trees fruit in 3-6 years, producing up to 200 avocados by year seven. Seeds take 10-15 years. Don’t bother unless you want a houseplant. Learned that the hard way.
Harvesting Is Confusing
Avocados don’t ripen on the tree. They only soften after picking. So, pick one, leave it on the bench. If it ripens within two weeks, the rest are ready. If not, wait and test again later.
Hass goes dark purple-brown when ripe. Reed stays green even when soft. Colour is not everything.
Store at room temp. Want them faster? Paper bag with a banana or an apple. Works every single time.
Is It Worth It?
That first homegrown avocado, though. Warm from the sun. Sliced open perfectly creamy. Tastes nothing like the hard imported ones from shops. Just give them what they want. Sun, drainage, and shelter.
