Here at Pikaplant we have a soft spot for Coffea arabica. It was one of the first species we ever used in our Jars and our oldest specimens have been with us for over five years!
The Coffea is a robust, hardy plant that thrives in the Jar environment. It is also resilient and will recover well if you need to remove sick or damaged leaves and stems. Check our tips below for advice on what to do should you run into an issue.
Condensation is part of the natural water cycle inside of the Jar and is a great indicator of how suitable the position of your Jar is. Ideally, one side of the Jar will be fogged up during the day. The plant will need about a week to acclimatise to a new spot.
If the Jar is completely foggy after 2 weeks, it is probably because the temperature in that spot changes often. Try moving the Jar somewhere with a more stable temperature.
If this does not do the trick, leave the Jar slightly open for a day or two to balance the humidity. Or open and lift off the top to wipe away the moisture with some clean paper towels.
Dry brown spots on leaves can develop over time as a result of diminishing resources within the Jar. For the overall health of the plant some brown spots on the leaves are no problem at all, so you can just leave it the way it is!
If one or more leaves develop black spots, it is a sign of a disease infecting the entire stem. This infection might spread to other stems if not dealt with. Simply open your jar and remove the stem to prevent this happening.
If a Jar Coffea isn’t getting enough light, some leaves may turn an olive green colour and start drooping or falling off. This can affect several stems of the plant at the same time, but if you catch it early enough only a couple of leaves might be affected. If a stem starts to show these symptoms, get in there, remove the entire stem, and move your Jar to a brighter spot.
Fungus is always present in the soil whether you can see it or not. Some fungi can be a threat but others are harmless or even essential! A plant’s natural defences are usually enough to protect it.
If the stems or leaves are sick however, this can be an ideal opportunity for fungus to infect a stem. Harmful fungus often looks white and fluffy. If you see this, you should remove the stem it appears on.
Small insects can sometimes emerge from the soil. Little flies or spiders usually do not cause any harm. You can open the Jar and let them out if you want.
Caterpillars, however, have a huge appetite and will damage the leaves. If you spot half-eaten leaves there, you should keep an eye on your Jar. Find and remove the caterpillar, and remove any damaged leaves to prevent disease.
We do our best to prepare your Jar for the dangers transport poses to a fragile product. However, if your Jar has been jostled or shaken too much, soil can spill onto the glass. It would be a shame to let that spoil your view! This can easily be resolved by opening up the Jar and wiping the inside with some clean paper towels.
