Dragon Fruit Cactus Grow Instructions

Dragon Fruit Grow Instructions

    Soak the seed — Although fresh seed (no more than a few months old) can be sowed without pre-soaking the seed, the germination rate of older seed can be greatly improved by pre-soaking the seed. Place the seeds in pure water (distilled, rain or reverse-osmosis water, not tap water). Older seed that has become dehydrated (has dried to some extent) will float. Soak the seed until most of the seeds sink rather than float, soaking for up to several days if necessary. The seeds can be separated from the water either by pouring the water onto an absorbent surface (such as a folded paper towel) or through a porous surface (like a folded paper towel). Soaking is especially important if you have doubts about how fresh or old the seed may be, as many sellers don’t say. Soaking It is an important first step to produce the best germination possible. Expect seed that is more than a year old to take at least a few more days to germinate than fresh seed would, despite rehydration, but even seed that is two or more years old can have a surprising germination rate if the seed is pre-soaked before sowing.

    What kind of soil? — The “soil” should be a growing medium a very low-nutrient mix based on sphagnum peat moss, with other ingredients such as silica sand or perlite optionally added. No “potting soil” (usually has nutrients added) and no Miracle-Gro brand because they enrich their sphagnum peat moss and perlite with plant food. My favorite mix is 50% by volume of sphagnum peat moss (which is dark brown; not light-brown long-fiber sphagnum moss) to 50% silica sand (not beach nor river nor children’s sandbox “play sand”).What about coir instead of sphagnum peat moss? Although desalinated coir can be used in a growing mix for reasonably mature, using coir for germinating and the initial growing of Dragon Fruit seedlings (instead of a traditional sphagnum peat based medium) can be problematic. Coir is so spongy and springy that after watering, the mass of growing medium heaves upward as it dries, especially near the top surface, and often partially uproots tiny Dragon Fruit seedlings or makes it difficult for them to establish their first roots.

    Do not bury the seed — However, it’s OK to gently press the seed into the surface of the growing medium with a thumb or finger, or to sift a little fine dust of sphagnum peat moss (ground between the fingers, for example) onto the growing medium to settle around the seeds, to help retain moisture and keep the emerging root from drying out and becoming calloused and stunted. This also helps give the seed something to push against as the root emerges and seeks to dig itself into the medium instead of merely pushing itself along the soil surface, but it is not strictly necessary.

    Water — Use only rain water or distilled water (or reverse-osmosis water). To water the seeds, use a spray bottle to gently wet the soil surface or continue to spray to saturate the medium until some water drains out, or water from below, allowing the soil to suck water upward through the drain holes from a tray or bowl of water. While germinating seed the soil should be fairly moist. Later when the plants begin to grow well the water content should be lowered and the plants allowed to have more air and less water in the soil. Dragon Fruit, once they are past the tiny seedling stage, grow very healthy in just moist rather than soggy or saturated soil, although care must be taken so that the soil never completely dries out.
   
    Heat — Yes, keep the seeds and growing container warm. A temperature above 78 degrees Fahrenheit or fluctuating up to 90 degrees Fahrenheit (24-32 or more degrees Celsius/Centigrade) will greatly help to stimulate more rapid germination and early healthy growth.
   
    Keep moist and avoid direct sunlight — Don’t allow the soil surface to dry out completely, and try to keep humidity high during germination, although it can be lowered once the plants are growing. If you live in a dry climate, it helps to germinate Dragon Fruit Seeds in a covered container. A disposable plastic food storage container makes a fine germination chamber. Cut or punch holes in the top for heat escape and air circulation, and poke some tiny holes in the bottom of the container to drain excess water. Place some growing medium inside (an inch or two (4-8 centimeters) in depth), sprinkle the seeds on top, and moisten thoroughly. Lift the lid of the container at least once a day and fan the air for a change of fresh air. The germination chamber should not be placed in direct sunlight because it will overheat both the air and soil inside and may damage or kill the seeds and germinating plants. Bright indirect light is best. Alternatively, the seeds may be sown in any regular pot or planting container, and temporarily covered with a clear plastic bag in indirect light. As with the germination chamber mentioned above, it is important to keep any covered container out of direct sunlight because of the rapid buildup of heat inside or beneath the covering, which can literally bake and kill seeds and seedlings. Once most of the seeds have germinated (within 4-6 weeks) the covering can be permanently removed and the seedlings then placed in direct sunlight.

    How long to wait? — Be patient. The freshest seed, sown only days or a few weeks after harvest, can often begin to germinate in as little as 10-13 days. Older seed usually takes 15-20 days or more before it begins to germinate, and seed that is more than a year old may require 25-days or more, and the germination rate (percentage of seeds that sucessfully germinate) is usually reduced as the seeds age. Soaking the seeds in water for a day or two before sowing, as mentioned above, can help to rehydrate dry, old seed and increase its germination rate. Warmth greatly increases the speed of germination of Dragon Fruit seeds. When the growing medium and air around the seeds are somewhat warmer than most humans find comfortable, seeds often germinate more quickly. Don’t give up too soon, and don’t let the soil surface dry and kill a newly emerging root from a just-germinated seed!
   
    Transplant — If grown in a germination container, Dragon Fruit can be transplanted after germination to a more permanent home, uncovered. The best stage to transplant them (this is merely my own preference) is after 2-3 weeks of growth in the germination container, when the cotyledons (the two first leaves, the “seed leaves”) are almost fully extended out of the seed and the first tiny true trap leaf is forming. At this stage the plant has a base and tiny root that can be transplanted, which helps to anchor the plant in its new growing medium and helps it to adapt to conditions of lesser humidity and more light. An easy way to transplant is to use a moist wooden toothpick. Poke a tiny hole in the new home of the plant, gently dig the plant with the tip of the toothpick, transfer the plant to the tiny hole in its new growing container and gently orient it properly (leaves up, base and root down) then very gently settle it into the new hole with the toothpick or a very light touch of a finger.
   
    Storing seeds — To store excess seed for later germination, place them in a small plastic bag or–if very fresh–in a paper envelope inside a plastic bag, and store them in the refrigerator. Keeping them cold helps prevent them from trying to germinate prematurely (warmth stimulates germination) and helps keep them fresh, and keeping them from drying out too much keeps them fresh longer and keeps their germination rate (percentage) higher. Placing them in a plastic bag and squeezing out most of the excess air keeps the seeds from drying out too much, and placing them in a paper envelope helps overly-moist fresh seed to dry just a little and keeps them from developing mold in long term storage. The plastic bag enclosing the paper envelope keeps them from drying out too much.

    If harvesting your own seed, allow them to dry in a small open container for 2-3 days before storage in the refrigerator.
