Malabar spinach also requires constant water, it has a high moisture content, in its native environment it has adapted to warm and very rainy climatic conditions. A lack of moisture will cause the plant to bolt / blossom which turns the leaves bitter and unpalatable.
Propagation - Malabar Spinach
Malabar spinach can be started from cuttings or seeds. Stem cuttings easily re-root in soil or water. Seeds can be saved for up to 4 years.
If starting from seed rough up the seed coat a tad with a nail file, sandpiper or some mildly abrasive material. It has a tough seed coat and the 'scarifying' will expedite germination and increase the success ratio. Germination is somewhat slow - taking about 3 weeks and unless you live in a warm region, at least USDA hardiness zone 7 or warmer they should be started indoors. Seeds started indoors should be planted at least a month before transplanting outdoors, preferably longer. Transplanted seedlings should be spaced roughly one foot apart.
If you live in a suitable climate the Malabar Spinach can be direct seeded about 2 weeks after the last frost date. You should still scarify the seeds when direct seeding. Soaking them overnight before planting is also a good idea.
Germination Temperature: 65 F to 75 F
Germination Time 14 to 21 Days
Soil Conditions Damp - Consistent moisture will prevent flowering, which will render the leaves bitter.
Requires High Nitrogen fertilizer to produce abundant Leafy Foliage. Apply a thin layer of high nitrogen fertilizer at the base of the seedlings. Wash the fertilizer into the soil. Some well rotted manure wouldn't hurt either.
A support such as a trellis is needed, it will grow successfully with peas on the same trellis but avoid cucumbers and squash as they are not compatible.
Well suited to higher temperature, flourishes in the the 90s F. Progress is retarded in cooler temperatures.
