What seasonal adjustments do cacti need?

Depending on their respective growth cycles, cacti and succulent collections may have care routines that vary from season to season. To accommodate the environmental changes that occur with each 3-month season, I adjust my care routine accordingly, taking into account changes in temperature and sunlight. For example, summer brings the need for dramatically increased watering, while winter conditions can be close to dormant. The transition periods of spring and fall may be my most critical times to ensure my plants are not stressed and well taken care of.

To facilitate successful transitions into spring, gradual time acclimation is needed. Water 2 x a week, increasing from winter watering amounts. Once it is favorable, move them to brighter locations over a period of 10 days. When new growth starts, begin applying fertilizer. For example, I have certain cacti that become radiant in color from proper spring transitions. Avoid sudden changes, such as those that cause root damage or sunburn, which can cause stress or damage.

Preventing damage from the sun is all about managing summer heat. For the hottest afternoon sun, employ 30% shade cloth. Water early in the morning to prevent loss from evaporation. Common pests, such as mealybugs and aphids, often become pests during these humid conditions. My saguaros love this protection from the heat while remaining in place during the hot Arizona summers, no fertilization during or even just before these extreme heat waves.

To prepare for winter dormancy, start in the fall. Gradually decrease watering by 50%. Do not fertilize at all. Move the plants away from cold drafts by windows. Provide consistent cool temperatures. After winter dormancy, my collection invariably blooms every spring that follows.
