  1. Thanks! This has really helped me plan out my permaculture olive grove. My only issue with all this underplanting is whether it makes harvesting the olives very challenging. We have only done one harvest last year and were sold the most enormous unwieldy nets (that’s the norm here in Italy – is it how its done in Greece too?). It was pretty hard getting them around the trees and then making sure all the olives were caught by the net. I’m trying to imagine how you could do it with other plans grown close by. Thanks!

  2. Hi Cleona, yes we use the same enormous nets here in Greece. The thing about companion plants for olive trees that it works perfectly for single trees planted in the backyard or potted olive trees for decoration purposes. However, even if you want to underplant olive grove you can use seasonal plants such as lavender, other herbs that will be in a dormant state when you harvest olives in late autumn and shouldn’t be huge harm if you put a net or step on them during olive collection time.

    Hi
    I am looking for ideas of what to plant under our very old large olive trees that are at least 100 years old. Their bases are nearly 2 m across and and the trees are approx 20 m high, so underneath is in heavy shade. We have hot dry summers and cold frosty winters. Annual rainfall is approx 350mm / year. (Southern Australia) Any ideas would be appreciated. Thankyou

  4. Greetings from Cyprus and thank you so much for your helpful list! I am not sure however I have seen any references to any Dacus repellent plants? I am planning on planting a couple of olive trees in my backyard for personal consumption (both for green and black olives and some olive oil down the road, to sustain my family of four) and considering that dacus is the most severe problem of the olive tree in our area, I would appreciate any tips you may have. I was considering planting a hedge of lavender coupled with some other Mediterranean herbs (for example: thyme, lemon thyme, oregano and rosemary), based on the plants’ same water needs and on how majestic it would look. But, after talking with some professionals and realising how severe the dacus problem has been in the recent years, I am willing to try anything to avoid the need for spraying and/or using traps.
    I am working with an empty plot so no limitations there :)

  5. Hi Michelle, ideally you should look for local plants that grow in shade or partial shade. Some examples of shade-tolerant plants with deep green foliage are Mona Lavender, Sweet Box, Winter Daphne, Silver Spurflower, New Zealand Rock Lilly. All these plants like well-drained soil, so you can implement an irrigation system to keep them saturated during the driest season. You can try to grow different species and expand the one that is the most tolerant of environmental conditions in your location.
