Jacarandas and the Hollandsche Waterlinie

6 Jacaranda's and a Delonix Regia (Flamboyant, Poinciana), and 4 bougainvilleas need planting. The holes are basically already dug by machine (thanks Antonio). The soil dug out needs to go back into the holes, mixed with compost and fertilizer. After the rains that is hard work. (Again! Who's a pensioner then? Well?)

A bit of a challenge is to initially water 7 big holes, and not resort to watering cans. Well, we have two quite long hoses, but we need about 70 meters here. Lucky there are three lengths of black plastic irrigation tubing. They can be interconnected using bits of the bigger blue hoses, while the blue hose fits the regular Gardena. All in all I can just about reach the last planting hole. Which is rather funny, as that is about 10 meters from the balsa, where the water is actually from:

Here is a movie of the Hollandsche Waterlinie, so you have an idea:

As we'll have a lot of wind coming days I extended the supporting bamboo sticks. Else the tops of the young trees are a meter above the end of their stick, and will possibly snap.
