|I installed several leather leaf mahonias last fall. The foliage on the plants (not all the leaves, but many) has changed from green to a yellowish tone. Is this normal, or is the plant experiencing stress? How should I treat the problem if there is one? Thanks
The plants seem to be stressed. Droughty soil or soggy wet soil both can kill roots and cause stress. Dig down a few inches and feel the soil to see if it is dry or soggy or just right. Spread one cup of lawn fertilizer (NOT a weed and feed) in a 4X4 foot area around each plant and water it in well. Then apply a mulch around the plants to hold moisture and keep weeds away.
Nilipanda mahonia kadhaa za majani ya ngozi vuli iliyopita. Majani ya mimea (si majani yote, lakini mengi) yamebadilika kutoka rangi ya kijani hadi rangi ya manjano. Je, hii ni ya kawaida, au mmea huo una mkazo? Ninapaswa kushughulikiaje tatizo hilo ikiwa lipo? Shukrani mimea inaonekana kuwa alisisitiza. Udongo wenye ukame au udongo wenye unyevunyevu waweza kuua mizizi na kusababisha mfadhaiko. Chimba chini kwa sentimeta chache na ukapige udongo ili uone kama ni kavu au umejaa maji au ni sawa tu. Kueneza kikombe kimoja cha mbolea ya nyasi (KWA KUWA si magugu na chakula) katika eneo la futi 4 × 4 karibu na kila mmea na maji vizuri. Kisha weka mulch kuzunguka mimea ili kuhifadhi unyevu na kuzuia magugu.
