So when you’d like strong crops with giant, vigorous bulbs that develop a number of show-stopping flowers, let’s get into the simple steps of when and find out how to fertilize amaryllis crops.

Whether or not you’re potting up bulbs to drive them indoors or rising amaryllis out within the backyard, you may feed your bulbs at planting time by mixing in a little bit of bone meal to their rising medium.
Including bone meal at planting time isn’t necessary and your bulbs will develop tremendous with out it, however I like to offer my bulbs the very best begin potential.
Bone meal is good for encouraging the event of robust, wholesome roots, because it has excessive ranges of phosphorus.
With an NPK (nitrogen, phosphorus, potassium) ratio of round 3-15-0, bone meal not solely helps with root improvement but it surely additionally encourages flowering – precisely what you need with these showy bulbs!
Use one teaspoon of bone meal blended into the soil when potting up bulbs in small indoor pots and one tablespoon for bigger planters or when planting open air.
Look ahead to New Development
After the bulbs are planted, the energetic fertilizing part for indoor potted crops begins with the emergence of latest progress, and never earlier than.
Whenever you first discover new progress sprouting from the highest of the bulb, I recommend utilizing a balanced liquid fertilizer however diluted to half-strength.
I’m a giant fan of the comfort of gradual launch fertilizers, however for bulbs planted in pots – particularly small ones – I want liquid purposes.
With liquid fertilizer, it’s simpler to manage the dosage quantities, to stop overfertilization.
And these merchandise present crops with vitamins rapidly, which is necessary for bulbs pressured to bloom out of season and out of their pure atmosphere.
After the primary feeding, wait three or 4 weeks or when the expansion is six to eight inches tall, earlier than fertilizing for a second time, utilizing the identical half-strength resolution.
When all of the flowers are spent and eliminated, begin fertilizing once more following the feeding schedule outlined beneath within the subsequent part.
Amaryllis might be fed a balanced fertilizer with equal NPK ratio, like 10-10-10, or a flower-boosting system with greater phosphorus ranges, comparable to 4-6-2 NPK.
Gardenwise Liquid Fertilizer
I like to make use of Gardenwise Liquid Fertilizer 10-10-10, obtainable in eight-ounce bottles from Walmart.
Water your amaryllis earlier than feeding so the soil is moist, however not moist – crops are higher capable of uptake vitamins in calmly moist soil than in a dry rising medium.
Feed After Flowering
The interval after flowering and earlier than dormancy is essential for the well being of the bulb and its skill to reflower.
It’s throughout this post-bloom interval that the leaves are actively processing daylight into power via photosynthesis, with the bulbs rising bigger as they convert power into sugars to retailer as meals.
Throughout this “inexperienced plant” part, potted specimens ought to be fed recurrently each two or three weeks with a liquid or water soluble fertilizer.
Water calmly to moisten the soil earlier than feeding, then use a half-strength software of a gentle, balanced fertilizer comparable to 5-5-5, or a flower boosting combine just like 5-10-10.
You too can use the product advisable above, simply you’ll want to dilute it to half-strength.
Proceed to feed your crops recurrently till it’s time to allow them to enter dormancy.
Cease fertilizing container-grown amaryllis across the begin to center of August in order that they cease rising in preparation for his or her relaxation interval.

Within the Backyard
For amaryllis within the backyard, feeding begins as for indoor crops, or as quickly as new progress emerges.
When your crops begin rising in spring, apply a two-inch layer of compost as a prime dressing over the foundation zone.
Or they are often fed with a gradual launch system with a balanced NPK ratio just like 10-10-10 or a flower boosting ratio like 4-6-2, scratching the granules into the floor of the soil.
All the way down to Earth has a wonderful natural product with an NPK ratio of 4-6-2 that’s best for outdoor-grown amaryllis bulbs.
All the way down to Earth All Goal Combine
You’ll find it obtainable from Arbico Organics in quite a lot of bundle sizes to fit your wants.
Vegetation might be given a second software of compost or gradual launch granules in early summer season after the spent blooms have been deadheaded.
You too can use a liquid fertilizer if that’s what you favor.
For liquid feeds, use a full power software after new progress emerges and as soon as once more when the crops are six to eight inches tall.
Don’t feed once more till after the flowers are spent and light, then fertilize month-to-month till the start of August – withhold fertilizers after this level to make sure your crops cease rising earlier than their dormancy interval.
Blooming Brilliance
With their implausible, trumpet-like flowers, amaryllis are a winter deal with when pressured indoors or a spring delight out within the backyard!
And with the proper fertilizing regime, you may get pleasure from their blooming brilliance for a few years to come back.
Bear in mind to attend till new progress seems earlier than you begin to feed your crops and provides them one other dose a couple of month later.
After that, wait till after flowering to feed them once more, then present common purposes till it’s time for them to organize for dormancy.
