container fruits for the summer
I posted something very similar to this in the Southern forum (no replies yet), before realizing that the Container forum existed (which seems more pertinent to my question), and it seems more active in here.
With the new year underway, I've (of course) been thinking about spring and summer gardening. I have very little in-ground space that gets good sun, and my residence is temporary, so I use ground for annuals; I've actually only just recently gotten into gardening, so the vast majority of my experience involves annual veggies and herbs. The best sun is on my large deck. It is south-facing and gets full sun most of the day. I received a 'Meiwa' kumquat and have been learning about caring for it here on the forums (first step: gritty mix transplant). This has gotten me pretty excited about growing more perennial plants (particularly edibles, a category which I guess is dominated by fruits) in containers.
My reading indicates that there are a LOT of fruit tree/shrub varieties that can be grown in pots. I've been looking at Raintree Nursery, Almost Eden, Pine Island, and some others, and everything looks so great, I want it all! But it's expensive, and I'm quite the novice, so I must be wise in my purchases. I'm interested in blueberries, raspberries (really any berry, I'd guess), as well as various apples and citrus (meyer lemon looks promising, and 'Moro' blood orange!), not to mention the much smaller strawberries. Unique things like avocados, pomegranates and honeysuckle (apparently some have edible fruits?) are also exciting to me. Some of these listed take years to start fruiting, though, and that's not ideal for me yet. I'm just having a hard time figuring out which plants take how long to mature, not to mention how old the plant will be when I purchase it...
All of the available information is overwhelming, much of it seems conflicting, and I don't know which fruits would actually be best for my situation. For instance, I plan to move away from here (Louisiana, zone 8b) in August, which is kind of prime time for fruiting for lots of plants (very frustrating!); therefore, I would much prefer fruits that will produce this year, and the earlier, the better (May-July harvest would be beautiful). The smaller, the better, too, since I'd like to bring most of my perennials with me when I move. However, smaller means less fruit, so I guess I mean 15 gallon pots are really pushing it. Also, I'll probably move somewhere slightly cooler than here, but only zone 7ish coastal areas, and I'm willing to bring any containers inside for winter months as necessary. I'd like to eventually grow plants that may require a few years of growth before production, but not until after moving.
So, with all of this in mind....
What fruits/food do you grow in containers? What are your favorites, and why? Any suggestions for my situation? (extra points for tastiness, bounty, and hardiness). Any other advice you'd give a novice gardener, like other (cheaper, but reputable?!) online nurseries, what NOT to plant, whatever?
I'm interested in other beautiful plants, but would like to keep this thread limited to food, please.
Thanks in advance for your help!
