"In many ways it's been a trouble-free build - the difficult part has been sourcing the plants.
"We're using a lot of species that people won't have seen before, including some that are new to cultivation. Some are so rare that we have gone for near-relatives for elsewhere, such as Cyathea tree ferns from New Zealand.
"If you want roses, you have 200 different suppliers to choose from. But something like a 7m strangler fig takes a lot of travelling around to find and that's what has taken the most time."
James Wong, broadcaster and designer (Tourism Malaysia Garden)
"The sheer amount of stuff we had to bring down from Scotland was a problem - we had two lorryfuls.
"Although it's a courtyard garden, the build was quite complicated, and it took the full ten days. Everyone's been very helpful though.
"The planting also has to look naturalistic, which actually takes a lot of tweaking. The plants are also finding it a bit hot after Edinburgh - we have been out with the watering can when no-one's around."
Amber Goudy, garden design student, Scottish Agricultural College (Sustainable Highland Garden)
"Apart from the Fritillaria, which was a bit late, it's been trouble-free.
"We have a good relationship with a glasshouse manufacturer over the way who let us keep some plants there for three days to bring them on - and we have daffodils still in bloom now because the bulbs were frozen in January.
"This year Gateshead is the European City of Sport and after the show the garden will be rebuilt on the quayside, on the route of the Great North Run in September."
Bob Davison, horticultural manager, Gateshead Council
"The most challenging part has been how late everything has been. When we originally came up with the design, we didn't think it would be a problem.
"We then put things like the climbing rose in the polytunnel to push them along, but it hasn't worked.
"However, the important bit for us is the educational angle - on how plants can be used to cut crime while also benefiting communities."
