Help! Bonsai Needles Drying up!

11 years ago

Hello,
Recently I have repotted all my bonsai. All seem to be fine besides my black pine. The issue is that from the middle of the pine needle it starts to dry up and turn yellow. Also when i touch them they are Very weak and feel like are going to fall off. Could someone please help me as soon as possible I dont want my bonsai to die. Also please be specific with your awnser like if it might be a issue with watering, The area i put it, or the type of soil i should have.

Details: My soil is made of gravel, pumice, Manure, And a bag of bonsai mix which is missing rocks and such from it. I have placed my japanese black pine outside and it has sun light but not directly underit. I water my bonsai about 1-2 times every 2 days. Some one please help Thankyou!!

    Hi - First rule of bonsai - leave manure out of it, it's too strong and not necessary. Second rule :), don't water so often - pines like their soil to be more dry than wet in between waterings and especially in winter (it would help if you could post a pic so we could see the relative size of the tree/pot next to something like a pen, etc) and it would be easier to advise re watering - pine needles will appear to have dried when they're actually getting water too often. And why is the mix missing rocks?

    Hi - I can't see how large the pot or tree are relative to anything else (too close up), but the tree has to live outdoors for life, and no tree should be watered according to a schedule, but when needed... which is what we all have to learn when doing this (and it's not easy!). Let most of the soil dry out between times, though water well (til it drains out hole) when you do it. That wouldn't apply to most tropical plants, especially outdoors in CA, but pines don't like wet feet. You'll have to learn what your tree likes, and sometimes we lose trees while learning, so don't get too attached :). Find a local bonsai club and bring your tree to a meeting... get some hands on advice as it's the best way to go. Again, why is the mix 'missing rocks'?

    Thank you For helping Again and the mix was missing rocks because when i bought the bag online it was showing that the mix included rocks but when i got it all it had was some manure pumice sand. And my final question is Could you tell me how many precent of each item and what item i need to use to create really good bonsai mix. Thanks

    and... from

    is -

    "PINUS THUNBERGII/ JAPANESE BLACK PINE

    P. thunbergii is a native of Japan and is arguably the classic bonsai pine species. The Black Pine is a very vigorous tree commonly grown Japan in parks and ornamental gardens where heights of anything up to 25metres are commonly reached. Black Pines are very tolerant of poor conditions, surviving in nature on barren, stony soils. P. thunbergii has thick, dark grey-green needles up to 7-15cm long, though quite long, the needle-size can be reduced in length with the use of bonsai pruning techniques. Bark is purplish-grey and becomes very craggy and fissured with age.

    White pines are frequently grafted onto the more vigorous Black pine/ Pinus thunbergii rootstock to improve vigour and growth-rate."

    You water when the tree needs it. JBP's generally like to be kept on the dry side but anytime you put something on a schedule you run into problems.
