First look for aphids inside the rolled leaves, then give it a shoot of nitrogen at least.

Rooted cutting to me.

Weather can cause this effect on tender new leaves. Nothing to fear at this moment. Just assure that you keep it warm and never stand freeze

Aphids will cause a much bigger curling effect, but in the opposite direction, producing convex leaves. Dry spell and some and deficiencies can cause concave leaves but would be much more pronounced..

As you are in a very cold climate, maybe you should eval to regraft it in a Yuzu to achieve a better cold resistance of roots and a more forgiving indoor plant. You can't culture it in the garden in any case. Oranges aren't hardy.

Next time: caught and identify first, smash later. Your only sample is probably unidentifiable at this moment, so you'll never know if it was the real stuff or a similar native species.

> topping and heavy pruning shortens the lifespan of trees

It depends on species of tree, but basically is true, yup. Heavy pruning is bad for trees and can kill it at long term.

Is a very good candidate also...

Looks a normal behaviour to me in any young plant growing new roots. As long of the provided soil and culture   procedures are accurate for the species, it will probably survive.

No need to kill it. This caterpillar is clearly different from the Citrus eating species of Papilio. Definitely neither cresphontes nor thoas or aegeus fit. I did some research and it seems that European swallowtail is present in all Northern Hemisphere including also USA, therefore: Papilio machaon.

In America will feed on some wild Asteraceae (Petasites, Artemisia) and Apiaceae, and can eat also Ruta. No problem with any of those (Here are my free poisonous Hogweed, take all you can eat, thanks).

You can put it in a quiet box with some branches to pupate and wait.

Almost identical to Papilio machaon caterpillar (many good memories breeding this common European species). Therefore probably in the same genus (or in the same species) and most probably will turn into a big and beautifuly butterly.

P. machaon does not eat citrus, but can feed on other Rutaceae if its main nutritious plant (Foeniculum) is unavailable

If you provide your pond with this contaminated underground water, you'll probably kill the trouts

You need to make this water analyzed looking for metals if you plan eat this fishes

Is a single leaf composed by three parts (or a multiple cotyledon?), not three. Therefore some thing is sure: Your seeds are neither from Musa velutina nor any other Musaceae. Not even a Zingiberal. Is impossible with this leaf and this kind of venation.

Tri-arranged is not frequent in dicots, but monocots can have this arrangement in several families. Is common in Liliaceae and related families. Multiple cotyledons are not common in monocots, by definition.

Take in mind that your plant has a very high possibility to be poisonous at this moment. Don't eat any part  from this plant (even if eventually produces showy blue or red berries).

Temptatively, reminds me a forgotten Trillium bulb. I don't see any cotyledon so, probably not coming from those seeds. Mature Musa seeds are big, glossy and black in any case. Not like yours

If not Trillium, some Araceae would be my second option. And a mutated dicot, the third.

Lilium martagon is not like those and Fritillaria is unlikely. Trillium starts with a one leaflet phase that is not seem in the photos. Maybe Araceae with compound leaves like Amorphophallus should deserve a higher position in the rank of candidates. They start often with five leaflets but the number of leaflets in your plants could increase in some weeks

Dwarfism in herbaceous using plant hormones is not complicated to achieve. Has been done since decades, specially for 'one use' flower plants. Gigantism is easy also but fruit's taste don't worth the effort.

Tropical Fruit Discussion / Re: Fruit thieves
« on: June 13, 2019, 06:20:28 AM »
There are three kinds of fruit thieves. 1) People picking one or two fruits one day, for hungry or curiosity, 2) people stripping the entire tree for selling the fruit and 3) non human fruit thieves.

I'm more forgetful about two of them than the other. Children are children and foxes patrolling the fig tree all night deter rats (and erradicate vermin the rest of the year) so they pay several times the fruit with environmental services. I imagine that living in a tropical country with wild monkeys could be a different situation.

I'll not report a new mailman without talking with he/she before; and my advice would be to not disclose the presence of cameras still and see if the mailman deserves a confidence vote or not.

If it grows over the fence anybody is welcomed to pick it, unless breaking branches or thinking that I'm stupid. There is a lot of english and french backpackers traveling and I couldn't care less. I'm happy to share my fruits with neighbors also. If it grows towards the inner side, is for my family.

I had a lot of elders making noise with umbrellas and even a "very white" man descending from a expensive car, dressed as golfer (shorts, cap and all the stuff) pretending to exercise its swing in the street, with the very obvious purpose to hit my walnut with the golf stick when nobody is looking. The little man smiling defiant to me was so ridiculous and annoying that I stand in place until he got tired of waiting, and I removed all fruits hanging over the street in the very next day.

Not ladybug, but a Golden Tortoise Beetle!, probably from genus Aspidimorpha. They eat plants but are incredible beautiful creatures mimicking poisonous frogs.

Temperate Fruit Discussion / Re: The endangered butternut
« on: June 03, 2019, 07:12:23 AM »
As this is a local problem, many people in Europe hadn't heard about it probably.

In resume: Juglans cinerea (an american tree relative to walnut) is declining fast, killed by Ophiognomonia clavigignenti‐juglandacearum, an asian fungus with three strains in USA. Other problem is that the original species could be being replaced by hybrid trees undistinguisable but more resistent to pathogen

A non virulent strain of the fungus were present before 1960s and a different strain much more virulent was introducted in MInessota and Wisconsin around 1967.  In some places more than 75% of the trees were wiped and natural regeneration is not going well.

The mortality is patched showing that the kind of ecosystem is important. Optimal habitats for restoration may be different from habitats where butternut has historically occurred. Trees survive better in dry upland places and inside bigger mixed forests, but saplings aren't shade tolerant so need some disturbance of the forest to stablish.

This is a common error. Many of the "dead by poison" caterpillars were dead zombies yet. Poison kills the caterpillar and the parasitoid wasps that were inside many caterpillars. Result, "Y" caterpillars dead plus "20 Y" butterfly killers dead.

Unless everybody uses poison there, less wasps and more caterpillars will survive in the next years.

But If everybody uses malathion, some people will fall ill by chronic exposition. And if you just stop using poison, will suffer a exponential increase in butterflies by lack of predators the next years, forcing you to use poison again. Is a vicious circle.

I'm tired to explain this again and again, but frustrated people will do it anyway. Outraged people loves the idea of fair revenge and will spend money in tools for that.

Poison means that they are supporting, promoting, increasing the plague suffered in they own plants. Predators are hugely influential. First course of Basic ecology.

Is a short palm with horrid spines, therefore they need space (will turn into a nuissance in small gardens or greenhouses), and will have the common palm problems and requirements

Tropical Fruit Discussion / Re: Australian Finger Lime Culture
« on: May 28, 2019, 06:13:02 PM »
UPDATE. A couple of lime finger misteries solved.

1) The 60g fruits is not a myth. Lime fingers definitely can make much bigger fruits. I had seen one last weekend, in the middle of a shrub loaded with standard fruits. More than double of the standard width.

2) I did some research about the strange RodneyS plant with leaves very different from Microcitrus australasica. Definitely NOT the common australian finger lime...

I was given an Australian Finger Lime from a friend.  I belive it's the green kind.  Can't wait to try those citrus pellets


... BUT, can be still a finger lime.

Probably one hybrid from the species Citrus wintersii (formerly called Microcitrus papuana). If that, RodneyS could expect mint-green finger lime fruits with whitish green crystals.

Wow, such a beautiful creature in any case

Yup, definitely could sacrifice gladly some fruits for that:

A longer harvest period (and fruits mature in the right months), could be more important than a big production.

Clementines are more sweet than acidic, small, easy to peel and seedless. Children love all of those traits, but take in mind that this trees are vigorous and have thorns and a relatively short harvest period. Clemenules is a good standard variety.

Navel oranges are seedless, much bigger, stand better in the tree without losing a lot of quality and can be more versatile. All navel oranges are good to eat. Some are better for juice than other. Cara Cara is a nice curiosity but Washington is perfect, as Lane Late (late) or Navelina (early)

White Oranges are specially good for juice, but have seeds, and sometimes vicious thorns. Are also more yellow orange than the Navel group. I would pick the former.

Tangerines and Tangors are more acidic than Clementines (a more interesting mix of flavours for some people) and have seeds (that is often a problem with small children). Alternaria is a problem often with Tangerines. The variety Safor is resistant.

Try to provide as many manure as possible in any case and choose carefully the rootstock.

After a spanish book, seeds are the edible part when cooked.

In any case I don't have direct experience with it, and those seeds could be from other species, so be careful.

Other uses: Has some healing effect, Spoons are made from its wood. Leaves are used as cattle fodder and eaten by deer, and flowers attract birds

A narrow tree that stands shadowed spots, fits in small spaces with a splendid massive floration in spring and a second floration in fall sometimes (less profuse). Just for the flower this jewel from the Antarctic flora would deserve a space.

I dont have direct experience with, but some could be more vigorous than the other. I suppose that you could put a permanent mark of some type (paint?, tags?, engraving?) before to mix it Just in case some variety starts overshadowing the less vigorous ones.
