Light appears to inhibit germination. Seeds can survive submersion in water for at least 8 months and can remain viable for several years in semi-arid soils. Viability decreases rapidly after 1 year in cool, moist soil conditions. Moving livestock that has browsed on fruits can disperse seeds to new locations. Lack of soil moisture during the warm growing season discourages seedling survival.
Mechanical removal can encourage clonal reproduction and spread.
Plants colonize sites by producing new shoots from lateral roots. Digestive scarification may increase seed germination. Despite the thorny stems, A. pseudalhagi leaves and seed pods are highly palatable and readily eaten by livestock. Preventative measures such as the use of certified weed free hay and restricted grazing where A. pseudalhagi is present are recommended. Severed rootstocks may also be spread to new areas by tillage equipment.
