I alternate between a couple of them; always with added vinegar due to my irrigation water pH of 9+. Most often it is Liquid Gold (Master Nursery/EBStone) [15-6-3] Then, Foliage Pro [9-3-6] And lastly once every 2 months (and because i bought a bunch of it years ago-cheap) Miracle Grow - very weak solution. this is not a cheap method, but its the only way i have found to feed the citrus during the heat season and keep it growing without using excessive water. [there are improvements and changes that i need to make to the irrigation, but unable to attack that project at this time. So i am stuck with what i have for now]. I used to mix it all in a watering can and apply to pre-wet soil. I mixed for a 1 gallon amount, but in a full 1.5 gallon can (so a bit weaker solution). 1 can per tree (or more if taller than 6ft.). Today i tried a sprayer and believe it worked well. I used a Hudson hand-held sprayer that has a metering knob. I could turn the liquid addition off, and then adjust up to 1 Tbsp /gal. This turned out to be a much faster and more convenient method (45 citrus trees) so i think i will stick with it. -George

depends how many. it is normal for lower leaves to yellow and fall off as they age. Is there still growth on top of the plant? Does it otherwise look healthy? john

Hi Barb, you can use NEEM for the common red spidermites or two spotted spidermites. That is the one that is most commonly seen and NEEM will work pretty good on those. There are more rarely a broad mite which is more resistant to most pesticides that is better sprayed with Avid or other specific miticides. Are you new to growing angel trumpets? You can visit the brugmansia forum here on GW for more specific info on brugmansia and datura. I have over a hundred varieties now and they never cease to amaze me.

I'm thinking underwatering for the pots is the culprit, although overwatering can also cause the yellow leaf symptoms, though usually not so quickly here. Agree with Mad, going with heat stress & find it nearly impossible to overwater a potted rose in active growth as long as the pot size is adequate, the potting mix good & drainage holes functioning. Like Valrose, potted roses here are watered at least once a day & often twice when the day temps get to 80 & above. I water each one & then go back & water each again to make sure they're thoroughly watered each time. If we get a soaking rain, I skip the watering. Hot days after cooler ones increase water needs here. And it's not only the warmer temps, but the greater intensity of sunlight every year that affects plants whether potted or planted. In the last few years, plants that were formerly happy in part sun part shade conditions have needed more shade as well, which I also chalk up to the intensity cranking up. With such frequent watering of pots, I subscribe to the "weakly weekly" fertilizing routine, using Neptune's Harvest liquid at half rates for larger plants & quarter rates for younger ones, on a second watering of the day. A good bit of rain usually falls here year round, with cloudbursts & storms frequent over the growing season. Though the land is clay based loam, the roses were never more lush & happy than a recent Summer when storms came by daily. Agree with Mad here again, in those circumstances, even with the soil saturated to puddles, no roses (or other plants) seemed to mind at all. What we see as red pigments in rose leaves, such as apparent in new leaves, actually protect the leaf by dissipating heat. Mildew can be brought on by underwatering in heat here, but it's opportunistic, does't bleach leaves & treated by washing the leaves with water wand & making sure the roots have adequate water. Occasionally see older leaves bleach out quickly right ahead of or at the same time as a growth spurt occurs. Just some random thoughts over a late lunch break & likely not well organized, but hopefully food for thought. Are your pots protected from heating up in the sun? I'd water the pots a good bit more, the planted out roses too, and start them on the Neptune's once satisfied their water needs were met daily. The Neptune's also great as a foliar spray applied in early evening when the temp's below 75 & leaf stoma open to absorb it completely. Sue
