Is Sago Palm Poisonous
You should know that it is poisonous. All parts, but especially the seeds, contain a toxin called cycasin, which irritates the digestive tract, and in high doses causes liver failure.
How to Care for a Sago Palm
Sago Palm is a plant that, if given minimal care, will be beautiful. So, let’s see what they are:
How to Plant Sago Palm
This variety feels better in warm climates although it can withstand temperatures as low as 12.2°F (-11ºC) and also frost if you grow it in the ground. As for the temperature limit, 107.6°F (42ºC) is the maximum recommended, since it will not be able to withstand much after that.
Soil for Sago Palm
It is advisable to use forest soil, especially if it is mixed with organic residues. It needs well-drained soil.
Watering Sago Palm
Water every 5 days during growth.
If it is planted directly outdoors and receives direct sun, water more often.
Stagnant water is very detrimental to the cyca. It needs good drainage.
Fertilizer for Sago Palm
Usually applied in spring or late summer.
Feed it only when it unfolds a new tuft of leaves.
In summer add a fertilizer rich in potassium and trace elements.
It is preferable to apply too little fertilizer rather than too much.
Cycas revoluta Propagation
- By tillers:
The tillers can be harvested in early spring.
It consists of cutting the tillers that come from the base of the mother plant.
Cut as cleanly as possible with a very sharp knife and without a saw.
It is advisable to wash the wounds and apply sulfur powder or a fungicide.
Leave the young shoots in a cool, dry place for 1-3 weeks until the cut heals.
The cut area can be impregnated with rooting powder and then planted.
Seedlings can be planted in well-drained sterile soil once it has rooted it is transplanted into a pot with a suitable substrate for cycads.
- By seeds:
They are dioecious plants, having male flowers and female flowers on separate feet.
Soak the seeds for a couple of days.
Fill a pot with perlite and water well.
Push the seeds on the surface so that they are buried just halfway into the pot.
Do not allow the perlite to dry out.
Leave the pot in a warm place, as a high temperature in the substrate stimulates germination.
Perlite dries out very quickly, so you can use two parts perlite and one part vermiculite.
The germination time lasts several months; afterwards, they will need more time to grow, they are very slow-growing plants.
Sago Palm Care Yellow Leaves
The pruning of the Sago Palm should only consist of cutting the yellow or dry leaves, every time it is necessary. There is a very common practice which is to cut all the leaves to try to make them grow faster, but I discourage it. Let’s remember that plants perform photosynthesis mainly in their leaves. If we remove them, of course, it will grow another crown quickly, but it will do it by a pure instinct of survival.
Also, if this pruning is done in spring or summer, and/or with tools that have not been disinfected, we can weaken it a lot because several potential enemies will not hesitate to harm it. For example, the red palm weevil can kill the sago palm, and this is an insect that is very attracted by the smell of the sap that is exposed as soon as it is pruned.
Pests and Diseases
- Cochineal and fungus attacks are frequent due to excessive irrigation.
- Leaf with brown tips: lack of ventilation. Inadequate location.
- Loss of color in the leaves, tendency to dry out: poorly lit place, cold or excess humidity. Correct environmental conditions.
- Yellowing of old leaves, the lower ones, may be due to excess water or fertilizer.
- The new leaves or upper part (the last whorls emitted) turn yellow due to excess fertilizer or poor soil.
- If it comes from a nursery with screened light and is placed in full sun, it is damaged.
- The combination of heat, sun, and an insecticide can burn the leaves.
- Yellow spots and dry tips may be due to potassium deficiency. Apply a fertilizer with a high percentage of potassium (K).
