Fruit trees look kinda static, but they’re super dynamic! Hormones, enzymes, sugars – much goes on as they constantly adapt to the wet, dry, windy, hot, cold, pest, pathogens – add to that their innate push to grow you some delicious fruits and there’s a lot going on! Fermented stinging nettle and comfrey tea is a well timed December assist. I’ll walk you through how, in detail below.
Have a quick refresh through Novembers fruit tree to do’s – they all apply to December, especially thinning fruits!, so I wont repeat them here.
Get bird net on at the first sign the birds are getting into your fruits. It’s great to leave the net as long as poss to reduce the amount of shoots that grow through it.
Improve your berry crop
Berries have a small window of perfection – grab them at their best with a daily harvest and you’ll not only be scoring the fruit in it’s prime but also increasing the crop by stimulating new flowers AND (capitals because it’s so cool) breaking cycles of disease and pest. Believe it or not – harvesting is your number one pest management strategy.
Picking a ripe berry with a tiny hole is a small victory. Left another day that tiny hole becomes several and now you’ve invited in a whole new guild of pest. Perhaps begun by a shield bug, taken over by earwigs then fruit flies = berries full of worms.
It’s tempting to harvest only the good and ignore the not so good, but its important to pick them all. Leaving the over ripe, holey, mouldy, funky ones leaves food and nesting sites for pests, and if disease is present – it’ll harbour that as well. I harvest with 2 bowls – one for the chooks and one for me.
Simple huh. Best health and you get to max out on this incredible crop – homegrown, organic, fresh picked berries = super food! Get out every morning and pick, especially if wet weather is forecast.
Stinging nettle and comfrey tea
Fermented herbal teas are the kind of solution I love – easily made at home, deceptively potent and no negative fallout. At this time of year there are 2 in particular that come to the fore – nettle and comfrey, tag teaming to strengthen the foliage which in turn improves disease resilience by strengthening the leaf coating (cuticle).
Leaf cuticle, is a point of entry for pathogens, all of whom arrive in various ways. Some dissolve the cuticle with enzymes and sneak in that way, others are opportunistic – using openings created by wind/ pest/human.
Strengthening the foliage is simply done with the wunderkind duo of stinging nettle (urtica dioica) and comfrey (symphytum x uplandicum).
- Right about now, nettle is gearing up to seed and is at its peak silica content. Fancy silica being the mineral needed for this very job, at this very time. Nature aligns!
- Comfrey brings calcium (amongst other things), a key ingredient for fruit production. Adding it regularly from now on in, greatly reduces the stress that comes with low calcium levels.
Add a cup or 2 of your homemade fermented nettle and/ or comfrey tea, to your regular biological sprays or just use it on it’s own. Monthly if all is well, or as much as weekly if your trees are stressed in any way.
If you have none to hand, never fear – make a brew today. Tis super quick and easy and will be ready in about a week if weather is warm.
Make no mistake, these sprays aren’t the saving grace, rather the cherry on the top of your diverse, living garden. Trees themselves, are equipped with an almighty defence mechanism that kicks into action when pathogens come knocking, as long as the tree’s immunity is in peak condition.
Herbal sprays and other gentle inputs don’t have an instant visible impact, but they do add to steadily building and improving your overall system. Shift your focus in this direction with a few gentle, well timed nudges. That’s all your fruit trees need.
Citrus health check
How are your citrus trees looking? Healthy shows up as a goodly sized canopy of flat, dark green foliage, a strong frame and a lush vibe. Their health has a lot to do with how well you’ve chosen where they live and how well you’ve looked after the soil at their feet.
Can you see fungal threads throughout the mulch, and smell an enticing earthiness? Responding to poorly looking trees with bags of fert or loads of manure only brings sugar rich growths that seduce sucking insects and break the soil web.
If the pest pressure is beginning to build you have many natural options.
- A tree in good vigour can handle a degree of pests. Leaving them be calls in natural predators and strengthens the tree. Squashing or trapping is an excellent option when populations are larger.
- A poorly tree may need extra – spray with Neem.
Stay keyed in on the action. If you choose to intervene, do so in as gentle a way as you can.
Check young trees
Test the soil beneath 1 and 2 year old trees, and water as required. This is such an important time in their lives – they can dry out as adults, but not as youngsters. Let this happen and risk a poorly adult.
Saying that it’s useful to let them dry out a tad between waterings. This encourages their roots to go wide. (I use my calendar to help me remember when I last watered) A lovely woody mulch will help them go the distance, as will leaving the grass to grow up around them.
Oh, how I love your messages, and how brave you are to step out into a new world!
Question: I have put in a new grapefruit tree. It’s still in its first year and is LOADED with flowers. Should I thin those or wait until there are little fruit, and thin those?
Namaste, dear Kath
Dearest Trish – you are feeling the answer already – don’t thin the flowers, there will be a natural attrition and flowers will drop. Await the little fruits before thinning and as its year 1 you’d do well to remove all the fruits (the news no one wants to hear 🙂 ) or its too stressful by far. Lots of love, K x
I am in Wellington on the south coast. I planted a little bear lime last year, it clearly did not get enough sun and the only part that grew was a shoot from the grafting stock. I recently replanted and it looks happier but still only has 2 leaves (tonnes of flowers though). how do I encourage more leaf growth or alternatively do I just give up on this one and plant another in the sunnier spot
Hiya Jean, Limes need warm soil and warm air and once they become so stressed they are down to 2 leaves its time to begin again! If you do have a go with rescuing the lime, knock the flowers off. one lime needs about 7 leaves to support it.
Read through my citrus article https://www.ediblebackyard.co.nz/how-to-grow-great-citrus/ and take care of all the conditions. If your soil is heavy and cold then perhaps plant inside a tyre – a great way to warm things up!
all the best, K
Hi Kath
Thank you for your monthly newsletters, they are fabulous! Just wondering about the liquid feed and if you still recommend both the seaweed or fish choices? I see the fish hydrolysate comes in 2 options either the fish or with add biology. and ifyou have a preference? Im trying to decide which would be best for my home garden in Auckland. I used to collect seaweed from Auckland Harbour and add in EM1 but stopped due to the potential pollution in the harbour.. Regards Monique
Hey Monique, use either seaweed or fish ok. Don’t need both. I like to alternate one to the other as a bottle runs out because they each have their strengths. Others prefer one over the other. The seaweed I like is Agrisea or oceans organics. I just use the organic hydrolysed fish – the plain one! Enjoy, K
