Tip: If your soil is heavier (has more clay vs. sand), does not drain and/or stays wet for days at a time, the frequecy (how often you water) should be reduced but not the duration (length of time).
This is meant to be a guide only. As plants mature they may need more water. With overwatering new growth will be small, yellow and have weak stems. With underwatering, no new growth will appear, leaves will yellow and fall. Organic material is alwys recommended as it will improve drainage in clay soil and will aid sandy soil in holding moistue. |
