ok, I'll admit to being a "scroller" but it was only to catch up and so I could post! (Forgive me??
)
My avatar (<<<<<) is actually a dwarf, but not from The Dwarf Project. It's from the collaboration of a private individual (in Quebec Ontario) and a University in Canada introduced in 1991 - hence its name: Quebec 309. Although described by Tatiana as an OP 5' determinate, it has rugose leaves (fairly supple) and the steady production until a killing frost of 4-6 oz very tasty, juicy red globes. My production notes (2020-2022) states "highly productive, very tasty juicy fruit on a problem-free plant".
My other diminutive favorite (only grown one year, as I've been trying to find a VERY small support system for it........pssssttt
@NewYorkRita would you share that Amazon link to those 12" square cages?) is a native dwarf called Mountain Princess. It grows wild in the Monongahela mountains in West Virginia. it is a heirloom, 18-21" tall plant with regular leaves and produces round, red fruit averaging 5 oz. My production notes for 2020 state "lacy, highly branched plant; profuse flowering but when fruit grew it collapsed like an umbrella and diseases set in, ruining very tasty, juicy fruit". I DID stake it when transplanting it to my garden. . . and again after it started to collapse under its fruit weight, but it was futile.
In trying to find a manageable cherry tomato plant (to replace my unruly indeterminate behemoth with many local fans/friends of its fruit) I tried Tiny Tim in 2021. It wasn't a suitable replacement. Its DESCRIPTION said it didn't need staking; it did. And the flavor of its fruit wasn't even close to my indeterminate: so my search continues.
Oh, I aalmost forgot! I've grown dwarfs, determinants and even indeterminants (once only!! I learned!) in 5 gallon shop buckets (readily available at: orange, Home Depot; white, Lowe's and blue, Walmart. . . ). I drill two quarter-sized drainage holes (one on the opposite side as t'other. . . and BOTH just above the INSIDE bottom of the bucket!!) When I didn't like its color, I swung by the paint department and got a can of spray paint meant for plastic/outdoors. And I used paint pens (from a local Arts & Crafts store) to draw designs and stick figures on them!
Homer buckets (my choice from Home Depot) has a 5 gallon/20 dry quarts andor 2/3 cubic feet capacity; its dimensions are 18" tall and 12" wide. Cost? Less thaan $2. . . . AAND (for an additional low cost) you could buy the matching lid!
