Need Serissa help - yellow leaves, black tips

[news.utanet.at]

Hello friends,

Approx. 6 weeks ago, I bought a 20 years old Serissa.

Our problem: Since 1 week some leaves become completely yellow and fall off.
Some leaves - up to now less than 10 - get black tips.

How I took care so far:

Water: Every 2nd day as much as it drips out of the pan a little bit.

Fertilizer: Once a week Floragard Bonsai fertilizer (dosis as indicated 3 ml
for 2 l water, but not every 2nd day as indicated).

Position: Very bright with no direct sun, currently at around 26 degree C.

Cutting: Some days ago the first time. Had some new branches, looking OK.

Couldn't detect any insects or something similar.

Who can help me and my Serissa? Is expecially my method of watering and
fertilizing OK?

Best greetings and thanks in advance,
Manfred

P.S.: Can send photos on e-mail request, if helpful...

Your tree is getting too much water & not enough sun or air. It should be
outdoors for the summer in part sun. Leave it out until temperatures go well
below freezing, probably November. Don't water it until the soil starts to dry
out. Don't give it any more fertilizer until it recovers.

I'm not an expert, but I do keep a Serissa and it is in very good
health.

One thing I notice is that you fertilize every week, and I think that
every two weeks is generally considered best by a lot of people. I
fertilize mine every two weeks by soaking the pot in water that has
Superthrive and a bonsai fertilizer in it.

Once each month, I use Miracid in a 1/2 dose to keep the soil acidic.
The yellow leaves falling off is pretty normal from what I understand
when the serissa changes environments. It is my understanding that
they are very picky and when you change the amount of light or water
they get, the tree often drops many leaves.

Again, I'm not an expert, but I do have a very happy and healthy
Serissa that blooms a LOT and often, and that is the care I give it.
I'm sure those with more experience than I have will be able to give
more information or correct me if I've made any mistakes.

Good luck!
