Wow - that white one is stunning! Very spectacular. I also agree that the red and white striped one is xjohnsonii. Looks just like mine. It should be very fragrant. Chuck, the true johnsonii is valuable, mostly because they almost never set seed, so the only way to get them is by getting offsets. Your image is too blurry for me to see properly. But I'm sure you could find a great trade. The plant trade forum on gardenweb is great - just post what you have and what you are looking for. Or I'm sure you could sell on ebay. Thanks for sharing the beautiful pictures - I love seeing garden heirlooms!

Amber, check with your local ag agent, or one of the well respected citrus tree growers/nurseries in your area, Maybe not the person you bought the trees from, as their knowledge sounds a little wanting. New citrus don't need a lot of fertilizer the first year, but after that year, you should start fertilizing in the early spring (after any chance of frosty temps have passed), then 4 applications during your growing season, which would be roughly February through Sept/early Oct. The spots - not sure, can't really see them up closely enough. Doesn't look like an insect. Looks more fungal in nature to me, which I find odd since you're in such a dry area of the country. The damage to the leaves in the first photo could be from snails, earwigs or other leaf-eating bugs. I try not to treat (except for snails, which I use an iron phosphate snail bait versus a metaldehyde snail bait, as metaldehyde is very poisonous to dogs, and dogs are attracted to it. No so for iron phosphate snail bait.) You can also use Sluggo Plus, which is iron phosphate and spinosad, which will kill sails, slugs and earwigs. Patty S.

Ronald: Yes, I have two seedling abiu trees. One has fruited one time, but I never got to tatse the fruit as we went away on vacation just before they were ready to be picked and they were gone when we returned. Here are some pictures I posted previously in another thread on this forum. Unforunately this bloom pictured, was only on one of the trees, and no fruit set. Actually, this particular tree has bloomed several times over the past few years (and multiple times per year) and has never set a fruit. I may have to take the chain saw out and let it rest by the trunk of the tree for a few days to see if that gets any rise out of the darn thing. There is a wide range of quality of fruit on Abiu, just like in Star Apple. How did your's compare?

Oy yes...I'll take a pic for you..In fact I'd be glad to send you a bottle if you can't find it or if it not the pure oil... I really have not had to use that much since the plants in the warm room and regular houseplants don't get mites lately...But if they did, that is exactly what I would do... When you lay that plastic down, make sure it is the 4m or thicker so that when you step on it it won't rip, even double up on a layers...Put enough down so that you can fold the plastic up at the end of your pots making like a huge cup...You know what I mean...It will catch the water and you can water as much as you want too without it leaking on to your floor...It will most definitely keep that area humid as it dissipates and the fan on the floor blowing across it towards the bottom of your leaves will make the area most hostile to mites for sure! Use the window box fans you can get for 12 bucks..It will be your life saver! Please, let me see your set up once you have it..).. Only spray with Neem, half strength since it will still smother bugs without smothering your fruitlets and buds...You will be able to spray as often as you want without ruing the floors and your trees...You will be so happy you did this..Just watch out for your walls...If you have windows, you can just windex the solution off them. Give your trees a good rinse of water before you bring them in especially under the leaves and let me know what your set up looks like...You might not even want a greenhouse if you can get this right..I know you can! It is what I would do and it is what always worked for me...
