    Gary can you tell me if you think that all bio matter from a banana tree (lLeaves stems} would be a good substance to mulch in to a garden bed also if so would this provide a total spectrum of NPK values,,? Thanks in advance

    This is a really useful video.  Too many YouTube vids just tell you to do something, without telling you why.  I need to know why I'm doing something, and this video has all the info I need to understand my plants' nutritional needs.  Thanks for making it.

    I wanted to drop in a note to say thank you to you! Nobody explains things quite as well as you do and I find myself coming back to your tutorials pretty often. From a "brown thumb" urban gardener starting off a small patio garden – thank you !

    I just used that miracle gro 24-8-16 last night to water my veggie plants.  You said that is too high, did I damage my plants and what can I d to correct it?  Is there anyway I can dilute it more to lower the nitrogen?  Or just stop using it all together and use water.  So if not good for veggies what can I use this high value fertilizer for?  Thanks for this video its just what I was looking for!!  I also have k gro 15-30-15 is that ok to use on veggie plants?

    for the nitrogen you said to plant lot of bean and chop them and keep the root, so it will make slow nitrogen into the soil. But are been root really that rich in nitrogen?

    Lower the nitrogen unless you want the leaves such as lettuce, swiss chard etc. Correct?

    Few questions:
    How to apply a pee as nitrogen for the plants? Shoud it stay few days mixed with a water or to use it immediately ?
    Banana peel will it raise the acidity? I planted tomatoes in too acidic soil and the leaves turned yellow so i added an ash.Can i use banana peel compost tea if the soil is acidic?

    Hi Gary, so if I use the remnants of a barbecue with a wood mixture of a hardwood and also of a charcoal briquettes, would that ash be usable where if I added it to the Banana trees that are growing as a supplement to potash or should I add it to the compost for distribution ?  Thanks!

    Excellent video. I use AZOMITE in good quantity but still learned a lot from this video.  I try to keep it all organic and this info will help me big time.

    Thanks again, Gary, for another great video I've been searching the web for potassium help. I've had problems with my tomatoes the past two years, they have had orange or sometimes green shoulders and someone suggested I add  some extra potassium to the plants. Now I know what I need to do, thanks

    Good vid, have to disagree about inorganic Potassium however. Having started up a series of raised beds, filled with poor clay soil from around my yard I found the potassium deficiency signs you described in my tomatoes, As this was not fully understood until (as a K deficiency) until the plants were fairly mature.
    The soil is VERY heavy clay Potassium sulfate was used quite successfully to correct the K issues, however a double dressing was required to do this due to the very heavy nature of the clay (similar in structure to oxford clay.)

    As 200g of 50% K fertilizer was used per bed I would have had to have used 1.25kg per bed of an 8% K fertilizer to reach the same correction?

    sorry gary, one more question. I am trying organic next year. Do I need to filter the water to go in to the garden. I am on city water with all the chemicals they put in it. thanks,gary

    gary, do you ever use the little peat pots to start your transplants? my question is I have several left over from last year, either the plant died or did not do well so I saved the little peat pot. They are rock hard. I submerged them in water both cool and warm and planted some seeds. Do you think the seeds will come up. I just did it today. thanks,gary
