Kalmia latifolia (Mountain Laurel) cultivars

This is a genus with the requirements typical of the heather family. The growth of Kalmia latifolia and its cultivated hybrids is slow, typical of the species, and needs pruning to increase its spreading. All Kalmia latifolia hybrids require lighter fertilisation (the salinity of the soil solution should not exceed 0.4 mS) than rhododendrons, and permanent, moderate humidity. The substrate should always be visibly dry before irrigation. They favour well-aerated, sour soil (pH<5.5), with a greater content of limeless sand. Kalmias prefer some shade, they form exposed flower buds in the year preceding blooming. Kalmias are an excellent, evergreen supplement for rhododendrons. Due to some difficulties in propagation they belong to the plants most rarely found in nurseries and gardens. Kalmia latifolia is unjustly thought to be a plant difficult to cultivate, it only requires more patience and precision while fertilising and watering. Our farm is the only one in Poland which propagates and offers cultivars of this species. Kalmia latifolia bushes grow slowly, after 10 years they reach the height of 80-100 cm and are similar in diameter.
