Hi everyone. I'm posting from Manila, and hope to get some advice on my lemon and calamansi plants.
Please see pictures attached.
I got them about 6 months ago, they were small plants at the time. And they have grown taller since. I've been trying to grow them organically, using only epsom salts, coffee grounds, pee, and worm castings. I fertilize using any of those once a week. The soil is a mix of organic potting soil, some sandy soil, and compost. It is well draining. The plants are in my roof deck garden, where it gets full sun. Since we have El Nino right now, it sometimes gets quite hot, and there is also some wind. But it's not anything too strong I think. The smaller plants like my basil seem to do ok in the sun and wind there. I water as soon as the soil looks dry. Usually every other day.
My concern is that my plants, both the lemon and the calamansi, just don't look their best, or even really healthy. The leaves are pale green only a few of them are dark green. Some of the leaves are deformed from the start. They often just drop. The remaining leaves seem somewhat dry to me, and kind of brittle to touch (actually they feel "crispy" almost). They often get quite dusty up there, so I tried hosing the leaves every now and then to get them clean. And also I thought it might have been some kind of pest so I've been spraying them at night using a simple Ivory soap spray, that I leave overnight and hose of in the morning before the sun gets too hot.
Some of them have actually started to flower, but you only see a couple of flowers. And then they just turn brown and fall off. No fruits ever.
I'm new at this, so would appreciate your advise. I'd really like to stick to organic too.
Thank you very much
