What’s more, Edithcolea grandis indoor care is the same as caring for it outdoors.
Persian carpet flowers can grow in USDA hardiness zones 10b to 11b. With much more effort, you can grow the plant in zone 9b, but it is hardier in 10b to 11b.
– Getting Your Edithcolea Grandis
You can start your Persian carpet flowers by seeds, cutting, or seedling. For first-time growers, you should purchase edithcolea grandis seedlings from a nursery or garden shop.
Seedlings are easier to care for than seeds and cuttings, and the process of transplanting seedlings is very easy.
When your edithcolea grandis seedlings become large enough, you can get cuttings from them. After successful pollination, your Persian carpet flowers will produce seeds that you can start other plants with.
You should provide a well-drained potting mix for your Persian carpet flower. The substrate of this plant should be more porous than the regular succulent potting mix. You can buy a regular cactus mix and add grit or river-washed sand to it.
The potting mix of edithcolea grandis should not hold water for more than six hours if you want your plant to thrive. It should have good drainage abilities.
When you have purchased edithcolea grandis seedlings from the shop, you should carefully remove them from their pots and leave them exposed for 24 hours before you plant them in their new pots. After planting the seedlings, you should wait a day or two before watering them.
Edithcolea grandis needs as much light as you can provide. Give your Persian carpet flowers access to more than six hours of direct sunlight daily. Edithcolea grandis can also grow in partial sun, which means that they should be exposed to sunlight for four to six hours, but you should make sure that your plant is not showing any sign of light deficiency.
As an indoor plant, you should place your edithcolea grandis pot on the south or east-facing windowsills of your home. In winter, you can grow your edithcolea grandis plants by placing them under 12 or more hours of grow lights.
Water your edithcolea grandis just like other succulents, so only water it when the soil is dry. Make sure that you planted your edithcolea grandis in well-drained soil.
You should water your plant in the morning so that any droplets remaining in the stem or topsoil evaporate because of the heat of the sun that it gets during the day. In the growing season (spring and summer), water your Persian carpet flower weekly or when the soil is dry completely. You do not need to water the plant in the fall or winter.
Fertilize your edithcolea grandis monthly during the growing season. You can also use diluted (to half strength) succulent fertilizer. Another thing you can do is use organic materials to boost the nutrients in the potting mix. Eggshell and other dry organic materials are suitable for edithcolea grandis.
If you must use compost or other organic fertilizer such as rotted manure, make sure that you do not use too much of it so that it does not change the properties of the potting mix (i.e. the mix starts to hold water instead of draining water quickly).
If you have some Persian carpet flowers, you do not have to go back to the nursery for more. All you have to do is propagate the ones that you have. There are several ways to propagate edithcolea grandis.
– Stem (Cutting)
You can use pruning scissors to cut at least three inches of stem from the plant. When you cut the stem, place it on the new potting mix and continue to mist it with water daily for 10-15 days. In time, you will notice that the cutting is rooting from the bottom. When the stem starts growing, water it just like matured plants. so once weekly.
This method of propagation is the easiest, but there are other methods that you can try.
The fruit of edithcolea grandis has a lot of seeds that you can plant. Simply spread the seeds (not too many) on the potting mix and cover them with a thin layer of potting mix or pre-washed river sand. In 15-25 days, you should see that some edithcolea grandis have germinated.
You should re-pot some seedlings if you feel that they are too many for their pot.
This method of propagation is the least common method as edithcolea grandis rarely produce offsets or shoots. If your edithcolea grandis produces offsets, brush off the top layer of the potting mix to reveal the point where the offset is attached to the mother plant. Carefully twist the offset and pull it from the mother plant.
Keep the offset exposed for one to two days before planting. Remember that you should wear your garden gloves to prevent the plant spines from harming you.
Here are some common challenges that you can face when growing edithcolea grandis:
Rot is caused by overwatering. When you give your edithcolea grandis too much water, it becomes susceptible to fungal attacks. Fungi and other microbes acting on the roots of your edithcolea grandis cause the plant to rot.
You should wait until the soil is dry completely before watering your plant again. Also, cut off healthy parts of the plant, wait for a few days, and then plant them into a well-drained potting mix, if rot is starting to appear on it.
As a tropical plant, the Persian carpet flower is not winter-hardy. Edithcolea grandis requires a temperature of 71-80 F. If the temperature is too low, your plant may die. You should take the pots indoors and give them 12 or more hours of grow light daily to sustain them during the winter.
The flower of edithcolea grandis has a smell that attracts flies and other insects. These insects may be pests for you, but they help to pollinate the plant. Aside from flies, aphids and mealybugs can be disastrous to your Persian carpet flowers too.
