Cadence - Lucky you having a south/east baconly location. I am in the Okanagan, B.C. I am on a third floor condo too, but I face north east - which is alot more shady and leaves little choices but for shady plants. The first plant I thought of was the Honeysuckle They are valued for their pretty flowers, which are sweetly scented, and their decorative fruits, which birds find delectable. The climbing Honeysuckles are suitable for growing over a trellis, arch, or pergola, while the shrubby kind are great for growing in borders and rock gardens, and as hedges. Their trumpet-shaped flowers are borne from late winter or early spring to late summer and range in color from cream and light yellow to vivid scarlet and purplish-rose. They are followed by pretty fruits that may be white, yellow, orange, red, blue, and black. POTTING: These plants will live in almost any soil, though they prefer a moist loam enriched with organic matter. They will benefit from being mulched, except with manure, which promotes the growth of foliage at the expense of the flowers. Their roots should be in shade and most prefer part or even full shade, although some flower best with their heads in full sun. This should be perfect on your balcany if you can have the root base protected from the sun. The stems of young plants should be shortened to encourage early branching and produce a full, bushy plant. Once this is achieved, pruning should only be done to keep the plants in bounds and to thin them out once there is a lot of old wood. This pruning should be done right after flowering; Honeysuckles that flower in late summer should be pruned in early spring. Shrubby Honeysuckles should have their old flowering shoots thinned out and cut back to within a few inches of the old wood right after flowering. Another little [annual] plant I thought of for filling bare spots in containers and also for their fabulous scent is alyssum. The tiny white flower variety seems more hardy than the maulve/purple/blue - just my humble opinion. These tiny florals love sun or partial shade. They multiply fast, so fill in is quick! If you plant them near your sitting area, the fragance is so pleasant....

One problem could be that even "full sun" plants (needing 6+ hours of direct sunlight) are not acclimated to being placed in intense sunlight after we buy them. Many times they are grown in greenhouses during the autumn and winter months receiving sufficient light for growth, but this is nothing like the "el scorcharoo" hot spring/summer sunlight we situate them in. They probably are being in a shaded in a garden centre for weeks afterward too. I'm embarrassed to say as a professional horticulturist that I killed half of my CACTI collection one year by placing them in hot sunlight during the spring months, after they had been indoors receiving sunlight in a south facing window. Since they were no longer under a ceiling and surrounded by walls, that made all the difference. They burned up. Oh me, oh my. Take Jenny's suggestion and slowly over the weeks bring full sun plants into full sun.

Hello Tin The easiest way to prevent insect damage in your garden is to discourage them from coming in the first place. A healthy garden is the best defense. Pull out any weak plants.They may already be infected. If not, they will attract predators. Pull the plant and dispose of it away from the garden area. Build healthy, organic soil.Natural composting methods, mulching and top-dressing your soil with compost or natural fertilizer is the best way to develop strong, vigorous plants. Keep foliage dry. Water early so foliage will be dry for most of the day. Wet foliage encourages insect and fungal damage to your plants. See our page on drip-irrigation for methods of delivering water to the root systems without wetting the foliage. Disinfect. If you've been working with infested plants, clean your tools before moving on to other garden areas. This will reduce the speed of invading insects. Hope it helps! :)

I think the sky's the limit for you in your location if you are willing to move them now and then. You could even put them on those little rolling plant dollies (some even double as a tray) to make the occasional move a cinch. Of those you mentioned, passion fruit and avocado probably would not even need to be moved at all... I'm truly envious, as I was doing the indoor/outdoor potted fruit tree thing for a number of years, but my climate only allowed them to be outside for five months and I eventually gave it up. I did have some tasty tropical fruit from the plants now and then... Hopefully others will chime in from your area, and also those with knowledge of potted fruit trr culture/varieties...
