My pear gets attacked by pear slugs(saw fly), they don’t seem to care about my other fruit trees. Japanese beetles attacked my raspberries. Flea Beatles attack my eggplant. Vine borers my zucchini, cucumber Beatles…. You get the point. Are they all at different brixs? Or do they know what they like? Can I just feed the plant sugar?

@Orchardpeople 3 месяца назад

Great questions! You can test the brick and see what they need! Nigel’s book will help you: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HQirgcu6lJY.htmlsi=JMqIj3nDa8as_3uo and www.nigel-palmer.com/

I can buy into some of this, but explain if you can. I grow lush, beautiful, aromatic Basil and yet they get ravaged by Japanese Beetles at one point or another. And it seems like it's mostly on one or more plants while right next door is another perfect looking Basil that is untouched. Could this be a Brix difference even though the plants look exactly the same state of health?

drj Westfield Wisconsin what can you do to make your apple tree fruit not to be deformed? Can you over do jobs fruit tree spikes? Thank you for your time and help.

@Orchardpeople 11 месяцев назад

Sorry for the delay. I avoid those fertilizers! I would do a soil test snd only amend if necessary. Instead feed by mulching with compost in the spring! If the fruit is deformed it may be pests, diseases or nutritional. I’d need to see a picture

@Bigdadzhousegainz 3 месяца назад

If your compost is made via a couple bags of top soil that was thrown ontop of 6 months worth of grass clippings a year then added to yearly after that and table scraps daily then it only gets mixed when I throw some bones in there’s and raccoons do all the turning of compost pile and all is in a shaded area, woul this compost be ok to put on top of fruit trees in spring or is there a special compost needed?

@Bigdadzhousegainz 3 месяца назад

Thank y’all for this, I’m 30 minutes into this but before I forget are y’all saying the lower the Brix score the less nutritional value is going to be in the food? (Based on my common sense and taste buds I can tell the difference between let’s say Krogers/publix and the farmers market or dudes selling out the back of their trucks) But then based off of other webinars I think it’s 3-7 brix is the max score any gmo fruit will be capable of. So is eating a low brix fruit idk how to word this but is it similar to eating celery where there’s no nutritional value but your body uses energy to process it?

@Orchardpeople 2 месяца назад

Great question! Yes, a lower Brix score often indicates less sugar and potentially lower nutritional value in the fruit. Higher Brix scores generally mean sweeter and more nutrient-dense fruits. While low Brix fruits aren’t quite like celery in terms of nutritional value, they might not provide as many benefits as higher Brix fruits. Aim for fresh, locally grown produce for the best quality!

@Sarrett.Studios 15 дней назад

Let’s say you have a low brix, how do you increase it

@Orchardpeople 10 дней назад

It's helpful to use regenerative sprays: orchardpeople.com/homemade-fruit-tree-fertilizer/

@ChristopherPisz 9 дней назад

By increasing soil health. Get microbes in there by doing things like adding organic matter, perhaps in the form of compost. Try JADAM JMS an similar methods. Healthy soil takes time and effort, it is not something you can buy or fix with a credit card. Life needs to increase in the soil and as a gardener, you have to do everything you can to promote it.

@@ChristopherPisz Absolutely! I love what you said: "It's not something you can fix with a credit card." Slow and steady.
