g'day barb_tom,

not sure mate could be lots of variables?

some pic's may help.

but for indoor plants yes watch the watering but most importantly is light level they need good light and what we percieve by eye is not the same thing, also no direct sun through glass.

we used to just add some slow release fertiliser about once a year (buyt the long lasting stuff), so not sure what it is that she has sold you?

could also be that the older leaves are going to be lost as the plant adapts to its new conditions.

if you have white walls or using a say an a4 size piece of paper held flat on the wall you can do a light test.

hold your open hand app' 10"s away from the wall and see how well or not the shadow of you hand is defined, the sharper the shadow the better the light and the fuzzier the shadow the worse the light, the ideal a nice sharp shadow.

and the other enemy of indoor plants air conditioning and central heating. along with the normal dry humidity of indoors humidity can be increased by the addition of say a fish tank or just have some buckets of water around like 1 per room, also spray mist the foliage say every second day, or stand the potted plant on a tray filled with little stones and water added.

Hi, I have two Yucca plants which I transplanted from a neighbors yard about 10+ years ago. They have done fine until today. We were putting a stake in to hold up the flower stalk on one of them and we noticed they both were covered with a black, flying insect. And I do mean covered! We sprayed both plants with a general flying insect spray and they swarmed away or flew into nearby trees. My question is, do you know (without privy of a picture) what these might be? The flower stalks are over 6 feet tall so it was impossible for us to get a good look at them. They did resemble a small stinkbug bug, and they did fly. But other than that I can't say. I have searched the Internet and can find nothing that vaguely resembles what these were under "Yucca pests". Do you think we have rid ourselves of these pests? Any info will be greatly appreciated. Thanks.
