When can I sow these seeds?

[Anto989]

Hi all,i collected seeds from fresh fruits of:
-carica quercifolia
-moringa oleifera
-malpighia punicifolia
-sapindus mukorossi
-eugenia pitanga
-annona cherimola

can I wait next spring or some variety will not be still viable until then?

people say Moringa seeds go bad in a year
i planted some that were 4 years old, and got a over %50 germination.

Cherimoya and also carica should be good several years as well.

im no expert, but i would guess sapindus seeds will last a long time.
i would either use sandpaper or cutters to nick the seed. (very hard)
and it may take several months to germinate.
It takes about 10 years for the Sapindus mukorossi to produce its first fruit

ive sown a few fresh seeds of Acerola, and none came up so far.

Malpighia
Seeds are generally very slow and difficult to germinate, usually requiring from 6 to 12 months at minimum. Seeds should be kept in moderately moist soil at 70-85F. Plant seeds at 1/4-1/2" deep. Do not overwater. Use well-drained soil. Germination rates widely vary and germination is sporadic.
