GROWING GUIDE

Sow at any time of year.
Pre-sowing Treatment: Soak the seeds until the seed coat splits (this can take several weeks or even months) changing the water every few days preferably in a heated propagator, or on a sunny windowsill or above a radiator.
Sowing Instructions: When the seed coat splits, place in small pots of moist seed compost mixed 50:50 with vermiculite. The seeds should be half buried lengthwise with the split just visible at soil level. Place in a propagator or cover with a polythene bag and place in any other warm place (eg. on a windowsill above a radiator). Palm seeds often make a large root before a shoot so carefully check seeds regularly. When a root appears, pot up individually into 9-11cm pots. Germination can be erratic but should take place in 1 – 3 months.

Growing Instructions: Grow the seedlings on, re-potting as necessary and protect from frost for the first couple of winters. Harden off completely before planting out in a sunny, sheltered position away from strong winds which can tear the leaves. Protect with bubble wrap and/or a fleece jacket for the first few years and in very cold temperatures.

How to Propagate Sago Palm from Seeds

1. Selection of Sago Salm Seeds

You can obtain sago palm tree seeds from a nursery or collect them from flowering trees in early fall. Always wear gloves before touching a sago palm, as all parts of the plant are toxic. Its fruit has a similar size, similar to a walnut, with an orange or red color. To check which seeds are pollinated, place them in a bowl of warm water. Seeds that begin to float (as they lack endosperm, necessary for reproduction) discard them. Pick seeds that sink in water, as they are good for use.

2. Cleaning Sago Palm Seeds

Soak the seeds in water for 24-hours, as they’re are wrapped with a fruit wall, which should be taken off before planting. If you find it hard to remove the coating, submerge them again for a longer period. To prevent bacterial growth, wash the seeds in a solution (10-parts water to 1-part bleach) and clean them with water.

3. Planting Sago Palm Seeds

Plant the seeds in well-drained, sandy soil, using a 4-inch diameter container, sowing them sidelong in the soil. Retain one-third of the seeds above the soil and level it by tamping. When done, moisten the soil with water. Lastly, cover the pot with a plastic wrap to maintain the moisture.

Sago Palm Seeds Germination

Sago seeds start to germinate in the temperature between 70-100 F (21-37 C). Maintain the moisture of the soil during the entire germination phase. You can also place the pot on a heating mat to supply a constant temperature. The seeds will begin to germinate in about one to three months. When they do, remove the plastic wrap and move the pot to a warmer place with 75F (23 C) temperature.

Transplant the plant to a large container, when you notice at least three to four sets of leaves emerging. Though young palm seedlings do not need fertilizer in the beginning growth stage, but start nourishing the plant with a liquid fertilizer when it reaches its active growth phase.

The sago palm tree can be grown from saplings or seeds. However, before you plant the seeds, you have to prepare the soil and check if it is viable to grow the same.

  • The seeds of the sago palm are usually reddish-orange in color and feature in the size of walnuts. Before planting the seeds, you must check for the viability of the seeds, in order to produce healthy plants.

  • Take a large bucket and soak these seeds in it. Some of the seeds may float on the water. Remove these seeds and discard them as they are not likely to germinate.
  • Let the seeds soak in the clean water for approximately two days for the outer cover to soften. Changing water, twice or thrice in a day, will prevent fungal growth on the seeds.
  • Once the seeds are completely soaked, remove their outer cover with the help of a peeler. But make sure you wear gloves before you get to the task of peeling the skin, since the seeds contain certain toxins that may cause harm. Dry the peeled sago seeds for about two to three days before planting them.
  • Next, prepare a pot with a starter mix, which consists of coarse sand, peat moss, and perlite. This allows excess water to drain off and yet keep the soil moist. The indoor sago palm is a smaller variety of the sago palm and grows well in pots.
  • Place the seeds into the soil, with their flat sides facing upwards. Do not bury the seed completely into the soil, but keep a part of it exposed. With the help of a sprayer, water the seeds and press them deeper into the soil.
  • The pot should be kept in a shady place till the seeds germinate and let out small shoots. It may take approximately five months for the germination process. Once the leaves appear, transfer the germinated seeds to a larger pot.
  • It can take another eight to nine months for the roots to grow. Place these young plants into a larger pot, till the roots develop further. It will take three to four years. After the plant has reached a height of one foot, transfer it to the garden. Choose a bright, sunny place with well-drained soil, to plant the palm.

Planting sago palms in your yard will have an effect of a tropical place and make your house look more beautiful. With proper care and nourishment, you can enjoy the beauty of this plant for many years to come.

Accelerating germination time for sago palm seeds

Q. Is there a method to accelerate the germination time for sago palm seeds? Two seeds I planted required more than a year to sprout.

— J.M., Missouri City

A. Sagos, Cycas revoluta, are not palms, but members of the Cycad family. They do not bear flowers to produce seeds, rather they bear cones. The male cone appears on one plant, and the female cone is found on a separate plant. The sago female cone develops across the center head of the plant and is a fawn-colored fluffy-looking ball. The male cone is upright in the center of the plant. Sagos produce cones one year, leaves the next.

You can propagate sagos from offsets from the mother plant or from fertilized seeds. Clean and store seed in a cool place before sowing and allow them to age about three months. If you have old, dry seeds, soak them in water for 24 hours.

Sow seeds in moist sand in pots deep enough to accommodate a long root. When sowing, avoid burying sago seeds. Simply press them into the soil surface so that about a half of the seed is still above the surface. Keep seed pots warm.

Germination may occur in two or three months.
