Philodendron Hastatum Care in Detail
Philodendrons are tropical houseplants. But Philodendron hastatum may vary to some degree in the optimum care.
1. Sunlight & Temperature
Extreme light can burn the leaf tips due to high temperatures. But low light can spawn a bushy growth as the stems extend in search of light and etiolating leaves.
This Philodendron plant prefers lower temperatures at night, around 60°F to 80°F, but avoids going lower than the optimal range.
In such pitfalls, relocate your plant immediately to an area indoors with a south-facing window dappled with curtains.
Or choose an east-facing window that welcomes soft morning light.
Likewise, keep the plant under a partially shaded shack with a perforated ceiling. But mindfully cover it with a frost blanket to shield it from cold drafts in winter.
Winter is also the ideal time to locate your Philodendron under grow lights for 10-12 hours to nether the risk of cold outside.
2. Watering & Humidity
Philodendrons dislike soggy soil. So keep an adequate watering schedule by sustaining moist soil conditions.
Additionally, Philodendrons require high humidity levels between 50% and 80% due to their tropical habit.
Overwatered Philodendrons may suffer from root rot, and this effect may be seen in the leaves through curling and yellowing.
Contrarily, underwatering makes the soil dry, causing leaves to curl and turn yellow and crispy brown.
Low humidity may cause the leaves to lose their vigor and become droopy.
To fix the issues, use only filtered or distilled water and install a humidifier or group the plants that need moisture.
3. Soil & Fertilization
Silver Swords are fussy about soil requirements and need a balanced blend of soil components.
Wrong soil may harm the roots and interfere with the plant’s mineral uptaking ability.
However, you can also buy trusty commercial aroid mixes from online stores.
|Philodendron Potting Soil Mix||Fast draining and water retentive
Natural and devoid of any synthetic fertilizer
Includes earthworm casting as compost
|Premium Aroid Potting Mix||Contains charcoal, worm casting, and coconut coir for elevating the water retention
Large and chunky orchid barks allow the roots to move freely
Amended with perlite for extra drainage
|Ivymay Redwoods Organic Potting Mix||No need to add additional nutrients while implementing
Contains bark mixture from different trees, keeping a coarse consistency
Imbued with peppermint oil for fragrance and root health
|rePotme Philodendron Imperial Houseplant Potting Soil||Moisture holding elements to prolong the water content in the soil|
To feed Philodendron hastatum, you must supply the soil with a liquid NPK 10-10-10 fertilizer monthly in spring and summer.
This way, minerals remain in the soil for the following year but fertilize once every 1.5-2 months in winter when the plant goes dormant.
Excessive fertilizer cause fertilizer burn in which the leaf tips and margins turn brown and brittle. But less fertilizer makes the plant nutrient deficient.
You can prepare a good fertilizer by amending compost (cow dung), fish emulsions, or coffee grounds with average garden soil.
But if you want to go premium, get one from these links.
|Covington Liquid 10-10-10 Fertilizer||Careful balanced blend of the nitrogen, phosphorous, and potassium
Supports the vegetative growth of the plant
|Triple 10 All Purpose Liquid Fertilizer||Contains sea weed extract and amino acids
Easy to use and comes with a measurable guide
|Bonide Liquid Plant Food||Encourages lush growth of foliage|
|EZ-gro Fertilizer - Liquid Plant Food||Water friendly and contains a blend of macro nutrients|
Also, do not forget to dilute the commercial fertilizers in water to prevent excess salt buildup in the soil.
4. Potting & Repotting
Protrusion of roots from the drainage holes and falling or premature blanching of leaves indicate the time for repotting.
But, wait till spring to properly repot the plant as it will sustain less harm during its peak growing season and can develop new roots.
While repotting, soak the soil 1-2 days early, gently pull the plant out of the container by loosening the soil, and untangle its roots.
Trim off damaged roots with sterilized pruners, fill the new pot with fresh soil, and place the plant in the new pot.
5. Occasional Pruning
Indoor Philodendrons are comparatively safe, but pest strikes are not uncommon.
Thrips, spider mites, scales, mealy bugs, etc., are the usual intruders.
Similarly, diseases like leaf spots are obvious due to improper care.
Thus, maintaining good shape and removing dead or diseased plant parts need pruning occasionally throughout the year.
Leaf spots may also appear as small yellow patches on the leaf’s surface, growing over time and becoming brown or black. Similarly, Blights take over the tender stems, making them wiggly to appear and later dry out. These disease symptoms can progress to other parts.
Thus, keep these diseases at bay by offering your plant a weekly clean-up with water.
If the symptoms are visible earlier, spray with copper-based fungicides.
Also, you must locate the diseased plants separately to avoid the disease extent.
Likewise, dip q-tips in the neem oil and rub at the infection site to remove the pests, or chuck them away using your hands.

Philodendron Hastatum: All About the Growth Rate
Generally, Philodendron hastatum is reputed for its arrowhead-shaped, 3 feet long juvenile leaves.
The plant is also a swift grower attaining a height of 10 to 15 feet and a width of around 6.5 feet.
It can comfortably maintain a tower of 30 to 100 feet in its natural habitat under the right conditions.
Philodendron gains a new flush of leaves every month, and due to its climbing habit, the plant often requires the support of a moss pole to grow.
Besides, the peak foliar season for the plant falls in spring and summer, while the blooming time starts from late spring to mid-summer.
This Philodendron plant requires at least 15 to 16 years to enter a flowering phase, so it may only bloom at maturity.
Likewise, the plant rarely flowers in cultivation. But when it does, its inflorescence becomes well-noticeable with ‘spadix‘ and ‘spathe.’
Similarly, the spathe is a developed bract or leafy light yellow to green structure helping to attract pollinators.
Philodendron Hastatum: Toxicity
Like all aroids, Philodendron hastatum is toxic for humans and pets.
The ASPCA confirms Philodendron hastatum has toxic calcium oxalate crystals like other Philodendrons. So, it is harmful to humans, dogs, cats, and horses.
Nibbling the leaves or other parts can proliferate alarming symptoms in pets.
Your pets also show oral irritation, difficulty breathing, constant drooling, pawing the mouth, hoarse voice, etc.
If these symptoms are obvious, the possible culprit may be the oxalate crystals.
The toxins can also pass to humans while pruning or repotting the plant.
In case of ingestion, have some milk as the calcium helps to bind the oxalate crystals and alleviate the issue.
But if the symptoms are unruly, consider taking immediate medical attention by calling any of the numbers below.
Propagation Method for Philodendron Hastatum
Stem cuttings are a common way to propagate Silver Swords, and spring is the best time to do this.
Also, you can plant the cuttings in fresh soil or encourage the roots to grow in water first. And later, you can retransplant them in the soil.
For this job, you will need gloves, sterilized pruners, a jar and fresh substrate.
Propagation via Stem Cuttings
Start taking a healthy 4 to 6 inches long stem cutting from the mother plant by snipping a stem section with 3 to 4 healthy leaves and 2 to 3 leaf nodes.
- Place the cuttings in a jar filled with distilled or rainwater with rooting hormone. At least one node must stay underwater.
- Locate the setup in an area that receives dappling sunlight for 4 to 8 hours and cover the cuttings with a plastic bag.
- Observe the roots grow within 3 to 4 weeks.
- Remove the plastic bag after the cuttings develop roots.
- When the roots are about 1-2 inches long, place them in a moist potting mix about 2 to 3 inches deep.
- Fertilize and water the plants normally after they develop new leaves.
