Arrowhead plant grow and care – herbaceous vine epiphyte of the genus Syngonium also known as Arrowhead philodendron or Syngonium podophyllum, Arrowhead plant perennial evergreen used as ornamental plant, can be used in ground cover plant and also grow it as water plant, can grow in tropics, mediterranean or subtropics climate or as houseplant and growing in hardiness zone 11b+, also can grow in 10b-11a but need little protection in the winter.
Leaves color green can be variegate green with pink, yellow or white, leaves shape mostly in heart shape but there are varieties that it’s elliptic shape.
Humidity, moist soil, when grow as vine the plant need support trellising and better to spray the leaves, more than 15C (better grow more than 18C) and in summer better not 25C, but can survive 40c in deep shape and a lot of water (or as water plant), can grow as air plant or water plant, prefer rich soil with hummus and organic matter, better to use soil that absorb water and keep like perlite and peat moss, coco soil, and to keep moist in the soil with mulch.
What is the best way to start growing? Plant / Seeds sowing in the spring in temperature of 20C possible until 25, better to sow indoor because the temperature more stable, moist soil don’t let it dry / Vegetative reproduction from cutting it’s the easiest way, better to take stem with fresh root, but possible any other stems, possible to grow roots on the water or in soil need to keep the soil wet.
Is it necessary to graft or use vegetative reproduction? No, but it easy, for specific
Difficulties or problems when growing: Toxic plant
Planting season: All year, if planting outdoor in hardiness zone 11b better in the spring to summer, and in hardiness 10b-11a planting in the spring
Pests and diseases: Aphids, spider mites
Pruning season: All year
How to prune: Dead leaves and bloom stems, if grow as groundcover in pot better reduce the old stems and old roots in order to let it grow or switch to bigger pot
Size of the plant: Usually grow as small plant 20-60cm, but can grow as vine 1-10 m, 3-30 feet, need high humidity or to spray water on the air roots
Growth speed in optimal condition: Fast growing in well fertilize soil with big amount of water / Medium growing
Water requirement: Average amount of water / Big amount of water, watering need to be regularly and better not let it dry
Light conditions in optimal condition for growing: Half Shade (might be burn by the sun) / Full Shade with light, colored leaves require more light than darker leaves
Is it possible to grow indoor as houseplant? Yes, mostly grow indoor as houseplants the color pattern of the leaves disappear in bad light condition and dark varieties can grow with less light
Growing is also possible in a planter /flowerpot / containers: Yes, grow well in contained, it depend the way that has be chosen to grow if it’s as vine enough small pot, if as crowded plant ( like groundcover) better shallow pot and wide as long as possible, better start with a small pot and mover to bigger, this plants like water and over time the water destroy the viability of the soil in the pot, so highly recommend when switch the pot to bigger take part of the old soil out.
Growing as aquatic plant Root inside the water and the leaves outside, possible to put soil in the water and treat it as water plant in pond, grow the best on the hedge of the pond, fertilizer need to add few time a year and be aware that fish will eat the roots.
Growing as aquatic plant It is not recommend but possible, need to keep the plant in high humidity, spray that plant few times a day (or just to use in a cold mist machine) important to fertilizer the roots by spray
Bloom season: Can bloom all year, but mostly in spring to summer
