Seed Starting:

*If using cell packs, Sprout Island is recommended for use in cell packs sized 72 or larger.

Thoroughly moisten the mix with warm water before use.

Make sure it is well mixed so that there are no dry areas but be sure not to make it too soggy.

Fill the planting container to within 1/4 inch from the top and tap container to slightly settle the soil.

Plant your seeds according to the directions on the seed packet.

Water-in the seeds lightly without saturating the entire soil volume.

Place in lighting and temperature conditions as per the seed packet.

After the seeds have germinated, provide them with 12-14 hours of light per day, keeping them close to the light source to prevent leggy growth.


Root Cuttings:

Choose green, non-woody stems for taking tip cuttings.

Use a scissor or razor blade that has been sterilized in alcohol to make a clean cut.

Place the cutting on a flat, hard surface and make a clean slice through the stem on a slant.

Remove all but 1 or 2 leaves.

With a pencil or pointed object, poke holes into the moistened seed starting soil.

Dip the node end of the cuttings into water and then rooting powder if desired.

Carefully place the cuttings into the holes you made in your Seed Starter soil and gently firm the soil around them.

Place the container of cuttings into a plastic bag but don’t seal the bag completely, to allow some air flow.

Place the bagged cell pack, tray, flat or other container in a warm spot in the house but don’t put them into full sun until new growth appears and they can be removed from the bag.

Check regularly to be sure there is not so much condensation on the top of the bag that it is dripping onto the seedlings. If this happens, the seed starter soil is probably too wet.

Replace the bag and allow the Seed Starter soil to dry out a bit.

Check your cuttings regularly in case they start to rot before they root.

Remove any suspect cuttings as soon as you see evidence of rot.

Keep the cuttings moist and in a few weeks check for roots by tugging gently on the cuttings and testing for resistance. Once the cuttings have developed roots, they are ready to be removed from the bag and planted into pots of their own.
