I have a number of different species of eucomis growing in pots and one which has survived a northeast winter in the ground. My question and dilemma involves the potted bulbs. It seems the larger ones like E. pole-evansii become too tall and flop over at this time of year and actually leaves have cracked and broken off. Question is how deep should the bulbs be planted and could shallow planting contribute to the weak foliage? I try not to use to much nitrogen in the fertilizer and generally use a low "N" compared to the "P" and "K". Should the bulb be planted deeper? The growth habit of eucomis makes it a poor candidate for use of with traditional plant supports Arnold New Jersey
