tamarillo tree is starting to bear small fruit for the first time.
The past five days have been very hot and half the young fruit
have fallen off the tree. Could this be due to lack of water,
suspect your problem is lack of water. Tamarillos do not tolerate
long droughts and must be well watered when it is dry. Mulching
can be helpful. Many plants lose fruit when they are stressed,
and it sounds like this may be the explanation for your fruit loss.
Other things to watch
for include protecting your tamarillo from frosts, not cultivating
the soil too deeply around your tree (the roots are very shallow)
and making sure your tamarillo has perfect drainage.
Having more than one
tamarillo plant may improve fruit set you could try two different
Soil deficiencies are
unlikely, but you can add fertiliser (NPK 5:6:6, look for products
with this ratio or similar) in early spring and mid-summer.
Individual trees rarely
last more than five or six years, so don't be too disappointed
if your tamarillo does die after this time period.
