Dela-Plast specialises in the manufacturing of high-quality seed trays through plastic injection moulding. As a trusted wholesaler, we supply plastic seed trays—also known as Unigro seed trays—to major nurseries across South Africa and the African continent.

Our durable polypropylene seedling trays are designed for reuse, offering a lifespan of at least 10 years. They can be disinfected with ease, making them a cost-effective and environmentally friendly solution. The loose inserts or cells allow for the optimisation and consolidation of seedlings after germination or rooting. Underperforming seeds or cuttings can be replaced easily, ensuring uniform growth and maximising space—leading to higher plant yields per square metre and increased revenue for nurseries.

Our seed trays are specifically developed for forestry applications, making them ideal for tree species such as Pine, Eucalyptus, Wattle, fruit trees, nut trees, and various indigenous species. We also supply berry nurseries and support a wide range of plant types requiring deep root systems, including lavender, sugar cane, and even flytraps. The propagation tubes/inserts are available individually or with our plastic or galvanised propagation trays.

We are proud suppliers to industry leaders such as SAPPI, KLF, York, and PG Bison, with other valued clients including Sunshine Seedlings, CPS, and numerous large nurseries throughout South Africa. Our products are exported to countries across Africa, including Mozambique, Zimbabwe, Zambia, Namibia, Kenya, Uganda, Ghana, and as far as Sierra Leone. Our propagation tubes have even reached New Zealand!

At Dela-Plast, we are proud to support reforestation and carbon-building initiatives across Africa. Our seed trays play an important role in the cultivation of trees and plants that contribute to environmental restoration. We are honoured to be part of this mission and committed to helping grow a greener future for the continent.

Our South African distributors are Plasgrow (White River), Algoa Plastics (Gqeberha), and Growrite (Cape Town).
