Taking Care Of Mammillaria Nejapensis “Silver Arrows”

Ideal conditions

Mammillaria Nejapensis “Silver Arrows” thrives in warmer temperatures and requires partial to full sun. This cactus does best outdoors, though it may also be kept indoors if you have a window sill that receives sunlight all day.

Watering

Silver Arrows requires little watering – only water the plant when its soil gets dry to the touch. If keeping the cactus outdoors, rainwater may be enough for it. But make sure to check the plant out often and water it if the soil is dry and no rain is expected.

Do not overwater the plant – standing water at its root level will cause root rot.

In winter, the Silver Arrows cactus requires little to no water since it enters a dormant state. The cactus should do well without any water at all, but you may also lightly mist it occasionally. If misting the Silver Arrows cactus in winter, be very careful since root rot is much more likely in colder months.

Where to plant

Silver Arrows should be planted in a fast-draining cacti soil mix. For increased drainage, you may add perlite or pumice to the soil in a 1:1 ratio to the cactus mix.

Whether keeping the cactus indoors or outdoors, you should probably plant it in a pot. This will make moving the cactus around much easier, especially in winter when you should bring the cactus inside. 

Due to its light needs, the Silver Arrows cactus should be kept outdoors. This cactus likes partial to full sunlight and will do best under direct sun. But during heatwaves or on hot days, move the plant to a shaded location to prevent sunburn.

The Silver Arrows cactus may be kept inside as well, but you’ll need to have a brightly lit indoor location for successful growth. A sunny window sill would be the best option for this cactus. Again, on very hot days, move the pot to a shaded location.

In winter, you may want to move the cactus inside. Though Silver Arrows is somewhat cold hardy, it shouldn’t be exposed to frost for too long.

General care information

Mammillaria Nejapensis “Silver Arrows” tends not to be a heavy feeder, so it can grow pretty well without any fertilizer. But you may feed the Silver Arrows cactus a cactus fertilizer diluted to 1/4-1/2 strength once a month during spring and summer.

You will also need to repot the cactus at some point. It’s a fairly fast grower and will probably outgrow its pot soon, so you may want to repot it every spring.

Before repotting, allow the soil to dry. Once you get the plant out of the pot, check out its roots and cut away any parts that are rotten or damaged. After repotting, don’t water the cactus for about a week to allow it to recover.
