What are the guidelines on the seed pack? You should follow them for containers too. If it were me, just 4 or 5 about 6" apart. Most types I grow tend to stay low and wide. If too crowded, it leads to disease, lack of sun and fighting for food, regardless of where planted. I hate thinning, so plant sparse. It's less painful...lol.. Have you grown it before? How are you planning to use it? Fresh or cooked? You may want to start a few more pots. If cooked , fresh spinach wilts down to nothing and takes a lot for a meal. JoJo

A 10" pot should be quite full with 4-6 of the plants you mentioned. I like to pack my purely annual pots; the habit of the plant is as important as the height. If you've got plants that will trail over the edge, you can get more in there. And it depends on the shape of the pot as well; you can get more into a 10" square than a 10" round. I'll take greylady one further - if the packet says space 12" apart, for a pot, figure more like 3" apart. PV

If I container plant, just as the others have suggested I put one herb type per container. Depending upon the herb, it may also be just one plant in the container or it may be multiple. It really depends upon the plant and how I intend to use it. But since plants all like different amounts of water, different amounts of light, different soil preferences, etc. having only one per container works out best. You can always try putting a variety of different plants in the same container. See how it fares versus single plant/species pots. Gardening is a great thing to learn experientially. Eventually though, I think you'll come to the same conclusion we already have. ;) FataMorgana

Hi Jay, Voodoo Child is a H. polyrhizus HYBRID. Please check the link below for more info about H. Polyrhizus. H. Polyrhizus is not a self-pollinating variety, so it needs hand-pollinating. Voodoo Child variety is self pollinating. Also you can look at the thorns on the stem. Voodoo Child has single thorns, H. Polyrhizus has single thorns and many multi-thorns. My uncle got 2 plants from Home Depot 3 years ago, 1 red flesh (H. Polyrhizus) and 1 pink flesh (H. Untatus). The pink one has a lot of fruits but the red one doesn't have any fruit. He told me the problem of the red one a few weeks ago and I told him the H. Polyrhizus needs hand-pollinating. So just wait a few months to see if he get any fruit. Home Depot gets dragon fruit plants (and many other plants, & trees) from La Verne Nursery (please see the label on the pot). You might call La Verne Nursery and ask about your dragon fruit plant.
