fertilizing and watering bulbs

mid to late fall

Fertilize established beds in mid to late fall at the time when bulbs are establishing deeper roots and preparing for winter. The best ratio of fertilizer is a 9-6-6 of N.P.K.  To understand this ratio, you can link here to Fertilizing Lawns.

Use a slow release formula and sprinkle over the ground about a rate of one pound per 100 square feet.

If you fertilize your beds regularly this additional feeding isn't really necessary but if you don't fertilize at all, this fall fertilizer will produce the best results. It gives your plants a great head start in spring and helps keep them comfortable if you have encouraged deeper roots for over wintering.

Putting down mulch in the fall also creates an environment that's healthier for the root systems.  If you already have mulch, double check to see that there is a good thick layer; at least 2 inches thick.

early spring

Composting your beds in early spring gives your bulbs a good source of natural, organic fertilizer with a slow release effect. If the soil was not amended at planting time, topping off with some organic rich material like compost creates a nutrient rich, moisture retaining soil.

If you experience long dry periods especially during your bulbs active growth times, give them at least 1 inch of water per week.  And the best watering as is with most plants, best done at a long and slow soaking.

Try to water at the ground level.  Overhead watering encourages fungus diseases. Watering in the mornings also prevents damage from the sun's reflecting rays and loss of moisture from evaporation.
