Jiaogulan questions.

16 years ago

I've been growning Jiaogulan (Gynostemma pentaphyllum) from seed for the past few months. I started under lights in a seed starting kit with peat plugs where they grew fine until I re-potted them into a cheap six quart rubbermaid-type container with plenty of large drainage holes drilled in the bottom.

The soil is a mixture of miracle-gro organic choice potting soil (mostly bark and sphagnum peat) with gypsum and a large amount of perlite. (Only temporary until I can find a source for pine/fir bark fines... proving difficult.)

I water when the soil is almost thoroughly dry, being careful not to over-water due to the large amount of peat. I've only fertilized once with a half-strength miracle-gro liquid 12-4-8 mixed with epsom salt.

Now, on to the actual question. The newer growth is a pale yellow-green where as the original growth is a dark, healthy-looking green. A few leaves on all six plants have brown tips on both old and new growth.

I can't for the life of me find any information on this plant aside from a few suggestions which all seem to be contradictory. I was just wondering if anyone knew if this is normal or might just be due to the somewhat poor soil/container I'm using, and anything I could do to remedy the problem temporarily until I can find some pine bark and re-pot into a more suitable pot.

Thanks in advance,

-Troy

    I would fertilize again and leave the Epsom salts out of the solution. I would also try adding an ounce of vinegar to each gallon of water every time you irrigate.

    Some new foliage simply emerges lighter than mature foliage, or even a different color entirely. Pale new leaves do often suggest a deficiency of the nutrients considered relatively immobile in the plant, or a general lack of fertility. Sometimes, micro-nutrients are actually present in the soil in adequate amounts, but unavailable because of high pH. The vinegar will help neutralize alkalinity and hopefully lower pH.

    Thank you, it's much appreciated. The next morning I did just that and it might only be my eyes playing tricks on me but now it does look a healthier shade of green.

    The only problem is I dissolved the epsom in the 12-4-8 so I am stuck with it until I buy another quart. I could not find any analysis showing the MG 12-4-8 or MG organic choice potting mix containing any amount of magnesium, but the fields were normally just left blank. From what I've read, It also seems Magnesium doesn't change soil pH much, either.

    So basically, would I be okay just using the 12-4-8 + epsom or should I really buy a new quart?

    Thanks again,

    I'm very sorry - I misread your original post and missed the fact that you'd added gypsum to the mix you're using. The Epsom salts in the 12-4-8 is appropriate if you didn't add more than about 1/4 cup to the quart. You might not want to use it on soils that contain lime, though.

    That's good to hear. I only added about 2 1/2 tablespoons, so I should be alright.

    Hi Troy, how is your Jiogulan doing? I am new and been looking for this plant, and wondering if yours has produced seed and if you would like to trade. Hope to hear from you/B

    The Label states 2 Months Fertilization from Poultry Manure added to Soil. Poultry Manure,Sometimes can cause problems when in contact with root system.

    Addition: Chlorosis and Brown Flecking of Leaves can also be signs of Ammonia Toxicity. This soil might be releasing ammonia quickly due to the Poultry Litter.

    Hello. Forgive me for reviving a kind of old post, but I'm really interested in growing Jiaogulan also. There's really not much info out there on growing it, that I have found. How does Jiaogulan do in a container? Is part shade best? Would it make an OK indoor plant, for in wintertime?

    By the way, Michigan Bulb has Jiaogulan plants 50% off today. I just ordered one (first time I've ordered from them). Looking forward to growing it for tea.

    I'm planning to put it in a container, using Daddy Pete's Potting mix.
