Pachypodium Horombense i Apocynacia familien er en af de flotteste Pachypodium der kan kultiveres. Den kan få nogle meget unikke og flotte tykke former, men man skal have tålmodighed - den vokser langsomt. Planten vokser i naturen på de høje sletter i det centrale Madagascar - de samme områder som Brevicaule.
Planten bør dyrkes i mineralsk jord, men kan blandes med en smule plantejord, hvis man er god til at styre vandingen. Den tåler ikke at rødderne står i vand, og næsten ikke hvis der er lidt kulde - altså under 10 grader. Den bør stort set ikke vandes om vinteren - men står den ved dansk stuetemperatur om vinteren bør den vandes en smule en gang om måneden, så den ikke tørrer helt ud. Hvis planten skrumper lidt og bliver lidt blød, betyder det ikke at den er rådden og død, men blot at den bruger af sit naturlige vandlager. P. Horombenses vækstmedie bør have en pH værdi på omkring 4.
Pachypodium Horombense kan tåle fuld sol til en smule skygge. Men husk at det er skygge i naturen - ikke i en dansk stue om vinteren - hvor der kan være meget mørkt. Planten kan blive op til 1 1/2 meter i naturen, noget mindre indendørs.
Den har torne på hele kroppen, og blade i en roset i toppen af hver "gren". Blomsterne springer ud om sommeren når det er varmest - de er relativt store og stærkt gule.
General information about Pachypodium There are a number of rules to follow when growing Pachypodium regardless of species. Use small Pots. If you use large Pots , the plant will often have too large a root system, and the plant will use more energy to grow the branches, and you will not get the compact shape that they get in the habitat, which is most attractive. Small Pots means a pot that is not much wider than the caudex and not much higher than the caudex. Use a pure mineral growing medium such as pumice, possibly mixed with some perlite. Both minerals retain a little water, but allow larger amounts of water to pass through a pot and out again. In nature, most Pachypodiums grow directly on granite, quartz, limestone and sandstone. Fertilize with every watering. Use a low concentration of fertilizer and remember that the fertilizer in all the water that comes out of the pot during watering is not absorbed by the plant. Always keep the plant slightly moist - also in winter. It may sound a bit counterintuitive to keep plants dry in winter to avoid rot, but remember that you can also water a very small amount at the edge of the pot, away from the plant. Pachypodium needs a lot of water in summer, preferably every other day. Brevicaule in particular reacts very strongly to drying out. Pachypodium is in dormancy from December to February (approximately), flowers from April to June, and grows from June to November. Most Pachypodium need minimum 4hours of direct Light during the flowering and growing period from February to November. Only Pachypodium should be kept above 10°Celsius in winter - Bispinosum and Succulentum can however tolerate down to 0 degrees. Despite this recommendation, some of the Madagascar Pachypodium grow in places where it gets down to 5°C in winter, and at altitudes where it is likely to get even colder. Most Pachypodium (but not all) grows in nature in soil with a low acidity around ph 4-5. Lime. Lime in the water raises the pH value, so it is recommended to demineralize the water (boil it) before watering, or use rainwater. Some Pachypodium - especially Brevicaule should be sensitive to bacteria, this may be explained by the low pH value of their habitat soil, as bacteria do not do well in acidic environments. |
