Inside Our Nursery: How a Seedling Gets Ready for the Street

Every tree along Donholm's green corridor started the same way: as a seed, usually collected by our youth nursery team from a healthy parent tree already growing somewhere in the estate. Collecting locally matters, because seed from trees already thriving in Donholm's soil and rainfall tends to produce seedlings that do the same.

Once collected, seeds are sorted, and viable ones go into germination beds or polythene tubes filled with a soil mix the nursery team has refined over several seasons. Germination rates vary a lot by species, from a couple of weeks for fast growers to a couple of months for some of the slower indigenous trees.

The next stretch is the longest: months of watering, weeding and gradual hardening off, moving seedlings from shaded nursery beds into more direct sun as they strengthen, so they are not shocked by full exposure on the day they are actually planted.

A seedling is generally considered ready for the street once it has a firm stem, a healthy root system that holds the soil together when lifted, and enough height to survive the first accidental knock from a passing vehicle or careless boda boda. Getting a seedling to that point typically takes ten to twelve months from seed.

None of this is glamorous work, and most of it happens with no audience at all, which is part of why we started the youth nursery programme: it gives the people doing this quiet, repetitive work real recognition and a stake in every tree that eventually gets planted.
